AB  - that can most closely evaluate the biological activity of the drug of interest. For testing the potency
of antivenom, these are the methods used to assess cytotoxicity. The aim of this study was to evaluate
the most commonly used cytotoxicity methods for determining the protective potency of the antivenom
Viekvin, which neutralizes Vipera ammodytes venom.
Material and methods: The selected methods are based on different biological mechanisms: MTT
assay, based on the activity of cell oxidoreductase enzymes; crystal violet staining, based on the degree
of cell adhesion; trypan blue staining, based on cell membrane permeability, and propidium iodide
staining, based on measurement of nucleic acids of dead cells. The pro-apoptotic effect of the venom
was also determined with annexin V staining.
Results: The IC50 value of V. ammodytes venom obtained by these methods was very similar, while
the EC50 values differed significantly.
Conclusions: We concluded that the choice of the method used to measure the anticytotoxic antivenom
potency depends on the immunogenicity of the venom components that cause cell death; for each
venom/antivenom pair, it is necessary to select the appropriate assay separately, and at present, none
of the standard cytotoxic methods can be universally applied to determine antivenom potency.

AB  - Obesity is often accompanied by low-grade chronic inflammation and metabolic syndrome. It has been established that microbiota influences many physiological processes, including the development of obesity, and dysbiosis has been observed in obese individuals. In this study, we aimed to evaluate the impact of a new probiotic formulation, containing two probiotic strains and the bioactive compound octacosanol, on body weight, metabolic parameters, and concentrations of certain adipocytokines and appetite-regulating hormones in obese women. This double blind placebo-controlled supplementary intervention study included twenty-five women in the intervention group and twenty-three in the placebo group, and it lasted 12 weeks. Daily oral supplementation included 7 × 1010 CFU of Lactiplantibacillus plantarum 299v (DSM9843), 5 × 109 CFU of Saccharomyces cerevisiae var. boulardii (DBVPG6763), and 40 mg of octacosanol or placebo. Body weight, metabolic parameters, adipocytokines, and appetite-regulating hormones were assessed before (T0) and after the intervention (T1). After the intervention, significantly lower median concentrations of CRP (p = 0.005) and IL-6 (p = 0.012) were measured in the intervention group than the baseline, while the median concentrations of ghrelin (p = 0.026) and HDL-cholesterol (p = 0.03) were significantly increased. The intervention group had lower CRP levels (p = 0.023) and higher ghrelin levels (p = 0.006) than the placebo group. Significant changes in BMI between groups were not observed. In summary, although the new probiotic formulation showed beneficial effects on IL-6, CRP, HDL, and ghrelin levels, its potential effects on regulating triglyceride, insulin, and glucose levels require further studies before the novel dietary intervention could be considered a useful adjuvant therapy and an effective strategy for the management of obesity and obesity-associated comorbidities.

AB  - Porcine thyroglobulin was important in the discovery of alpha-Gal allergy. Here, the linkage of porcine thyroglobulin-specific IgE with IgE positivity to routinely assessed allergens and to the incoming diagnosis within a population of suspected atopic individuals is explored. IgE, IgA, total IgG and IgG subclasses to porcine thyroglobulin, IgE to bovine, human thyroglobulin and meat extract were measured with ELISA. The following correlations were observed in IgE binding to porcine and bovine thyroglobulin (r = 0.910, p = 1x10−17), porcine and human thyroglobulin (r = 0.635, p = 4x10−6), human and bovine thyroglobulin (r = 0.746, p = 6x10−9) and porcine thyroglobulin and meat extract (r = 0.482, p = 0.0009). Only one out of ten samples which showed binding to porcine thyroglobulin in ELISA tested positive with ImmunoCAP alpha-Gal, implying different epitope/s. Increased IgE binding was detected towards a more electronegative fraction of porcine thyroglobulin separated according to charge and the binding could be partially inhibited by galactose. Anti-thyroglobulin IgE was found in 29.7% of the population, in subjects who were significantly younger, p < 0.0001 and it occurred more frequently in patients referred for testing penicillin specific IgE (OR 2.48, p = 0.0059) and were negative. IgE specific to porcine, bovine and possibly human thyroglobulin may be implicated in post-infectious skin manifestation misinterpreted as penicillin allergy.

AB  - Pertussis or whooping cough is a highly contagious, vaccine-preventable, respiratory disease caused by Bordetella pertussis, and transmitted through the respiratory tract. According to the reports of the World Health Organization and Centers for Disease Control and Prevention, the incidence of pertussis shows periodical variations in certain regions of the world. As humans are the sole reservoir of this bacteria complete vaccination against pertussis and high vaccination coverage is of utmost importance for reducing the incidence and severity of the disease. Two types of pertussis vaccine are available: wholecell (wP) and acellular pertussis vaccine (aP). wP contains whole nonviable bacteria, while aP usually contains two or more protein components. These protein components include inactivated pertussis toxin, filamentous hemagglutinin, pertactin, and fimbriae. The acellular vaccine was developed in response to reports of adverse reactions upon administering the whole-cell vaccine in certain countries. Both vaccines are usually formulated with diphtheria and tetanus toxoids, and more recently a trend of combining more antigenic sources such as Haemophilus influenzae type b, hepatitis B, and inactivated poliovirus vaccine has been accepted in many countries, including Serbia. The wP vaccine stimulates a strong immune response more similar to infection, while the response to aP vaccine differs in this respect. Due to the difference in the types of immune response predominating with different types of pertussis vaccines, there are differences in the duration of protection, and it has been reported that wP induces more durable protection. For countries that have adopted aP increased monitoring is advised as well as the inclusion of booster doses. The special focus is on the vaccination of pregnant women to protect the newborns. Incited by the recent surge in pertussis cases in Serbia here we provide a comprehensive literature overview of pertussis vaccines, covering their historical development, current status, challenges, and potential future directions.

AB  - Introduction: In recent decades, many efforts have been made in laboratories to develop alternative methods that would replace animal tests or reduce the number of animals used. In this sense, the methods for measuring cytotoxicity have proven to be very suitable substitutes for testing toxicity. As each individual substance being tested has its own specificities, it is necessary to carefully select a specific, appropriate cytotoxic method. This is especially important if the investigated substance is complex, such as animal venom. Also, antivenoms are drugs for which it is necessary to correctly determine the protective power.Methods: This study aims to evaluate most commonly methods for evaluating citotoxiciy of Vipera ammodytes venom and protective potency of appropriate antivenom. For this purpose, methods based on different biological mechanisms: MTT enzyme assay, Crystal Violet (CV), Trypan Blue (TB) and Propidium Iodide (PI) staining, were examined on Vero cells. The proapoptotic effect of the venom was also determined with AnexinV staining.Results: The IC50 value of V. ammodytes venom evaluated by MTT, CV, TB, PI (%) methods was similar: 62.5, 55, 66, 87 g/ml, respectively, and the most suitable methods for testing the cytotoxicity of V. ammodytes venom were methods based on the measurement of living cells, which were MTT and CV staining. The same methods were used to test the anticytotoxic potency of the antivenom and each method confirmed significant anticytotoxic potential, but the EC50values obtained by those methods varied significantly.Conclusion: Choice of the method used to measure the anticytotoxic antivenom potency depends on the immunogenicity of the venom components that cause cell death.

AB  - Background: Recent literature data highlights metabolic changes in amyotrophic lateral sclerosis (ALS). To explore possible early metabolic changes, we aimed to analyse the fatty acids (FA) composition of erythrocytes in newly diagnosed als patients and to see whether fatty acid levels correlate with the ALSFRS-R score or disease duration. Methods: The severity of motor function involvement was assessed by the ALSFRS-R scale at the initial evaluation. The fatty acid profile of erythrocyte membranes was analysed by gas-liquid chromatography. The study comprised 26 clinically diagnosed als patients, with mean ALSFRS-R 38±8. The control group included 26 healthy volunteers. Results: Significantly higher levels of palmitic acid and total saturated FAs were detected in als patients. In als patients, total monounsaturated FA, palmitoleic, vaccenic, and oleic acid were also significantly increased. The levels of eicosapentaenoic acid, docosapentaenoic acid, total polyunsaturated FA (PUFA) and n-6 PUFA were significantly lower in als patients. Additionally, a-linolenic acid, the precursor of the n-3 PUFA family, was not detected in als patients. We found no significant correlation between the ALSFRS-R score and the abundance of individual FAs analysed. A moderate negative correlation was found between disease duration and DHA level, and a positive correlation was detected with MUFA. Conclusion: Experimental evidence presented may contribute to shaping a beneficial nutritional intervention.

AB  - U ovom izlaganju biće predstavljeni naši dosadašnji rezultati na temu antimikrobnih antitela kod profesionalnih sportista, odraslih osoba koje se ne bave profesionalno sportom; promene nivoa antibakterijskih antitela pri starenju; poređenje specifičnosti serumskih i salivarnih IgA antitela kod mladih odraslih osoba, kao i nivoi ukupnih i antibakterijskih antitela u Covid-19 virusnoj infekciji i u sepsi. Nivoi i titri antimikrobnih antitela različitih klasa i potklasa određivani su ELISA testom iz uzoraka seruma, plazme ili salive. Ispitivano je vezivanje za izolovane antigene mikroorganizama (lipopolisaharid, peptidoglikan i zimozan) i za cele mikroorganizme, različitih vrsta i sojeva. Vezivanje prečišćenog salivarnog IgA za mikroorganizme praćeno je i protočnom citometrijom. Od rezultata izdvajamo da izlaganje fizičkom naporu visokog intenziteta dovodi do promena na nivou antibakterijskih antitela, i to u pravcu sveobuhvatnijeg prepoznavanja lipopolisaharida1. Suplementacija profesionalnih sportista određenim probioticima dovodi do održanja nivoa ukupnih salivarnih i serumskih IgA antitela, kao i IgG antitela specifičnih prema Enterococcus faecalis, koja su u ovoj populaciji pokazala sezonsku varijaciju. Pri starenju dolazi do smanjenja nivoa antipneumokoknih antitela i to zavisno od pola, pa su stariji mukarci naročito pogođeni ovim smanjenjem3. Salivarna IgA antitela razlikuju se po specifičnosti od serumskih IgA antitela i pružaju nespecifičnu zaštitu. Poređenje pacijenata sa sepsom, hospitalizovanih Covid-19 pacijenta i starosnih kontrola pokazalo je brojne razlike u nivoima kako ukupnih, tako i antibakterijskih antitela. Nivoi antibakterijskih antitela kod pacijentata koji nisu preživeli bili su niži nego kod onih koji su preživeli, što potvrđuje značaj ovih anititela za preživljavanje sepse.

AB  - The size of circulating immune complexes (CICs) in rheumatoid arthritis (RA) could be an emerging criterion in disease diagnosis. This study analyzed size and electrokinetic potential of CICs from RA patients, healthy young adults, and RA patients age-matched controls aiming to establish their unique CIC features. Pooled CIC of 30 RA patients, 30 young adults, and 30 RA group's age-matched controls (middle-aged and oldеr healthy adults), and in vitro IgG aggregates from pooled sera of 300 healthy volunteers were tested using dynamic light scattering (DLS). Size distribution of CIC in healthy young adults exhibited high polydispersity. RA CIC patients and their age-matched control showed distinctly narrower size distributions compared with young adults. In these groups, particles clustered around two well-defined peaks. Particles of peak 1 were 36.1 ± 6.8 nm in RA age-matched control, and 30.8 ± 4.2 nm in RA patients. Particles of peak 2 of the RA age-matched control's CIC was 251.7 ± 41.2 nm, while RA CIC contained larger particles (359.9 ± 50.5 nm). The lower zeta potential of RA CIC, compared to control, indicated a disease-related decrease in colloidal stability. DLS identified RA-specific, but also age-specific distribution of CIC size and opened possibility of becoming a method for CIC size analysis in IC-mediated diseases.

AB  - Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease, affecting motor neurons, which is characterized by the progressive loss of motor function. Sufficient evidence has been gathered, either in the form of experimental results from animal disease models or from the assessment of affected human subjects, which implicates metabolic changes in the course of ALS. Hypermetabolism, abnormal glucose tolerance and dyslipidaemia were reported to have high incidence in ALS patients. In fact, according to published studies, BMI is significantly and inversely associated with ALS progression. Here, we discuss basic principles of fatty acid metabolism, composition and the existing knowledge of metabolic and fatty acid composition changes in ALS patients. Literature data suggest that ALS patients have unfavorable changes in the fatty acid profile, especially because of the low level of long-chain polyunsaturated fatty acids. Nutritional interventions and supplementation with various foods or food supplements are currently not showing conclusive results, implying there is more to learn about potential ways to modify this illness.

AB  - The surface of microorganisms is covered with carbohydrates, which makes them unique, self-sustaining glycan probes. Lectins are able to bind to these probes, and this interaction can be exploited for selecting microorganisms or novel lectins. To examine lectin-microorganism interactions, we have previously developed an enzyme-linked lectin sorbent assay (ELLSA) with whole bacterial cells. To further test the validity of this methodology, here we compare it with flow cytometry. For this purpose, we used biotinylated recombinantly produced lectin from Musa acuminata (BanLec), this lectin’s recombinantly produced chimera with green fluorescent protein (BanLec-eGFP) and a lectin from Ricinus communis (RCA120), both biotinylated and FITC labeled. Parallel testing showed equivalent results for the two methods, in terms of the presence or absence of binding, with signal intensity yielding high Pearson correlation coefficient of 0.8 for BanLec and 0.95 for RCA120. The ELLSA method demonstrated multiple advantages, such as reliability and convenience for high-throughput analysis; it also required less lectin and yielded more consistent results. As such, ELLSA proved to be a useful tool for profiling microbial glycan structures or testing novel lectins.

AB  - S. pneumoniae is an important human pathogen which has a polysaccharide capsule with virulent properties. This work aims to estimate the titres of S. pneumoniae specific IgG and IgA isotypes, with respect to age and sex. An in-house whole bacterial cell ELISA was used for the determination of relative levels and endpoint titres of IgG subclasses and IgA1 subclass specific for S. pneumoniae serogroup 1, and to quantify specific IgG1 and IgG2 levels. Significantly lower anti-pneumococcus IgG1 titres were found in older individuals, which was more pronounced in men. Lower IgG2 titres were detected in men over 50 years of age, in comparison to women under 50 years of age. The levels of IgG3 and IgG4 did not differ between different sex and age groups. Lower IgA1 levels were detected in male individuals in both age groups in comparison to females under 50 years of age. The levels of IgG1 showed a moderate correlation with IgG4 in younger individuals of both sexes (r = 0.61 in men and 0.63 in women) which was not noted in the older age group. We highlight the deficiency in humoral immunity in older people, especially male and suggest immunization of this population with pneumococcal vaccines.

AB  - In vivo animal models can provide worthy information on various aspects of asthma mechanism and pathogenesis. The genetic predisposition and phenotype of mice may affect the immune response itself. Here we compare the early immune response to Der p 2 or HDM allergen extract upon injection and inhalation in BALB/c and C57BL/6 mice. Female C57BL/6 and BALB/c mice were immunized with Der p 2 allergen subcutaneously followed by inhalation of Der p 2 or HDM extract. After challenge, the mice were euthanized; blood, bronchoalveolar lavage (BAL), spleens and lungs were collected. Cells from BAL were identified by May-Grünwald Giemsa staining and lung leukocyte populations were analyzed by flow cytometry. Serum antibody levels of Der p 2 specific IgE, IgG, IgG1 and IgG2a were assessed by ELISA, and cytokine secretion (IL-4, IFN-γ and IL-10) was evaluated upon stimulation with Der p 2 or HDM extract. The Th2 immune response was confirmed by elevated allergen-specific immunoglobulin E (IgE) and the allergic reaction was evidenced by infiltration of eosinophils and/or neutrophils into BAL. We found that BALB/c mice were inefficient in integrating local with systemic immune response, evidenced by almost no IgG or IgE production upon one subcutaneous injection and subsequent inhalation of Der p 2 allergen; also, the bronchoalveolar lavage infiltrate in these mice consisted of neutrophil infiltration, unlike C57BL/6 mice in which eosinophilic infiltrate predominated. The differences between BALB/c and C57BL/6 mice strains could be exploited for generating different types of responses to the Der p 2 allergen.

AB  - Increased interest in microbiota calls for the thorough analysis of antibody reactivity to different microorganisms. As salivary IgA represents the first line of defence against microorganisms contacting mucosal surfaces, we explored the binding and specificity of salivary IgA by testing the binding of purified, FITC-labelled salivary IgA to different microorganisms in flow cytometry and conclude that this kind of analysis enables the differentiation of species/strains with high IgA binding capacity, which should be corroborated on a larger sample size. Further we compare, with in-house ELISA, the binding of polyclonal salivary IgA with the binding of polyclonal serum IgA from the same individuals to whole microbial cells and to purified microbial components. High correlations were obtained in total salivary IgA binding to Lactobacillus rhamnosus and Escherichia coli, very distant bacterial species, as well as to isolated bacterial components (r = .70–.97). The binding of total salivary IgA resembled the binding of both salivary IgA1 and IgA2, with IgA2 predominating. For serum polyclonal IgA repertoire, substantially higher specificity was obtained. Serum IgA binding to E. coli correlated best with serum IgA binding to lipopolysaccharide (r = .86), and serum IgA against L. rhamnosus correlated best with the anti-peptidoglycan IgA levels (r = .88). We have also detected that total serum IgA response is governed by either IgA1 or IgA2 response, depending on the nature of the antigen/s. We conclude that steady state salivary IgA repertoire, unlike serum IgA repertoire, consists of polyreactive antibodies with innate specificity, questioning its capacity to select resident microbiota.

AB  - OBJECTIVE: The aim of this study was to determine any differences in ox- idative stress and inflammation parameters in COPD patients treated with either N-acetyl cys- teine (NAC) alone or with NAC in combination with propolis (NACP). PATIENTS AND METHODS: Forty COPD pa- tients in the exacerbation phase were enrolled into the study and were treated with either NAC (NAC group; n=20) or NACP (NACP group; n=20) twice daily for one month. Redox status was de - termined by measuring superoxide anion (O 2 .– ), advanced oxidation protein products (AOPP), total oxidative status (TOS), prooxidative-anti- oxidant balance (PAB), malondialdehyde (MDA), ischemia modified albumin (IMA) and sever- al other antioxidant markers: superoxide dis- mutase (SOD), paraoxonase 1 (PON1), total sulf- hydryl groups (SHG) and total antioxidant status (TAS). Interleukins 6, 8 and 17 were measured as markers of inflammatory status. RESULTS: Both groups had similar socio-de - mographic and clinical characteristics. Af- ter treatment significantly higher SHG [0.446 (0.395-0.516) vs. 0.292 (0.270-0.325), p<0.001] and significantly lower TOS – 50.6 [49.7-53.4 vs. 73.2 (50.9-84.6), p<0.05] – and IMA [0.650 (0.629-0.682) vs. 0.709 (0.667-0.756), p<0.05] – were found in the NACP group compared to the NAC group. Factorial analysis indicated a larger oxidative stress-inflammatory load in the NAC group after treatment. CONCLUSIONS: From an oxidative stress and inflammatory status perspective, treatment with NACP was more successful than with NAC. The inclusion of propolis into therapy for COPD patients, especially those in the exacerbation phase, could prove beneficial.

abstract = "OBJECTIVE: The aim of this study was to determine any differences in ox- idative stress and inflammation parameters in COPD patients treated with either N-acetyl cys- teine (NAC) alone or with NAC in combination with propolis (NACP). PATIENTS AND METHODS: Forty COPD pa- tients in the exacerbation phase were enrolled into the study and were treated with either NAC (NAC group; n=20) or NACP (NACP group; n=20) twice daily for one month. Redox status was de - termined by measuring superoxide anion (O 2 .– ), advanced oxidation protein products (AOPP), total oxidative status (TOS), prooxidative-anti- oxidant balance (PAB), malondialdehyde (MDA), ischemia modified albumin (IMA) and sever- al other antioxidant markers: superoxide dis- mutase (SOD), paraoxonase 1 (PON1), total sulf- hydryl groups (SHG) and total antioxidant status (TAS). Interleukins 6, 8 and 17 were measured as markers of inflammatory status. RESULTS: Both groups had similar socio-de - mographic and clinical characteristics. Af- ter treatment significantly higher SHG [0.446 (0.395-0.516) vs. 0.292 (0.270-0.325), p<0.001] and significantly lower TOS – 50.6 [49.7-53.4 vs. 73.2 (50.9-84.6), p<0.05] – and IMA [0.650 (0.629-0.682) vs. 0.709 (0.667-0.756), p<0.05] – were found in the NACP group compared to the NAC group. Factorial analysis indicated a larger oxidative stress-inflammatory load in the NAC group after treatment. CONCLUSIONS: From an oxidative stress and inflammatory status perspective, treatment with NACP was more successful than with NAC. The inclusion of propolis into therapy for COPD patients, especially those in the exacerbation phase, could prove beneficial.",

AB  - The predictors of intestinal carriage of vancomycin-resistant Enterococcus spp. (VRE) among high-risk patients in the counties of the Southeast Europe Region are insufficiently investigated, yet they could be of key importance in infection control. The aim of the study was to identify risk factors associated with fecal VRE colonization among high-risk inpatients in university hospitals in Serbia. The study comprised 268 inpatients from three university hospitals. Data on patient demographics and clinical characteristics, length of hospital stay, therapy, and procedures were obtained from medical records. Chi-squared tests and univariate and multivariate logistic regressions were performed. Compared to the hemodialysis departments, stay in the geriatric departments, ICUs, and haemato-oncology departments increased the risk for VRE colonization 7.6, 5.4, and 5.5 times, respectively. Compared to inpatients who were hospitalized 48 h before stool sampling for VRE isolation, inpatients hospitalized 3–7, 8–15, and longer than 16 days before sampling had 5.0-, 4.7-, and 6.6-fold higher risk for VRE colonization, respectively. The use of cephalosporins and fluoroquinolones increased the risk for VRE colonization by 2.2 and 1.9 times, respectively. The age ≥ 65 years increased the risk for VRE colonization 2.3 times. In comparison to the University Clinical Centre of Serbia, the hospital stays at Zemun and Zvezdara University Medical Centres were identified as a protector factors. The obtained results could be valuable in predicting the fecal VRE colonization status at patient admission and consequent implementation of infection control measures targeting at-risk inpatients where VRE screening is not routinely performed.

AB  - Fluorescently labeled lectins are useful tools for in vivo and in vitro studies of the structure and function of tissues and various pathogens such as viruses, bacteria, and fungi. For the evaluation of high-mannose glycans present on various glycoproteins, a three-dimensional (3D) model of the chimera was designed from the crystal structures of recombinant banana lectin (BanLec, Protein Data Bank entry (PDB): 5EXG) and an enhanced green fluorescent protein (eGFP, PDB 4EUL) by applying molecular modeling and molecular mechanics and expressed in Escherichia coli. BanLec-eGFP, produced as a soluble cytosolic protein of about 42 kDa, revealed β-sheets (41%) as the predominant secondary structures, with the emission peak maximum detected at 509 nm (excitation wavelength 488 nm). More than 65% of the primary structure was confirmed by mass spectrometry. Competitive BanLec-eGFP binding to high mannose glycans of the influenza vaccine (Vaxigrip®) was shown in a fluorescence-linked lectin sorbent assay (FLLSA) with monosaccharides (mannose and glucose) and wild type BanLec and H84T BanLec mutant. BanLec-eGFP exhibited binding to mannose residues on different strains of Salmonella in flow cytometry, with especially pronounced binding to a Salmonella Typhi clinical isolate. BanLec-eGFP can be a useful tool for screening high-mannose glycosylation sites on different microorganisms

AB  - Background: The screening for intestinal carriage of vancomycin-resistant Enterococcus spp. (VRE) among high risk patients in the Balkan region and molecular epidemiology of VRE is insufficiently investigated, yet it could be of key importance in infection control. The aim of this study was to provide baseline data on VRE intestinal carriage among high-risk patients in Serbian university hospitals, to determine the phenotypic/genotypic profiles of the isolated VRE, to obtain knowledge of local resistance patterns and bridge the gaps in current VRE surveillance.

Methods: The VRE reservoir was investigated using stool samples from 268 inpatients. Characterization of isolated VRE stains consisted of BD Phoenix system, genotypic identification, glycopeptide and quinupristin-dalfopristin (Q-D) resistance probing, virulence gene (esp, hyl, efaA, asa1, gelE, cpd) detection and MLVA. Biofilm formation was evaluated by the microtiter plate method.

Results: VRE carriage prevalence among at-risk patients was 28.7%. All VRE strains were vanA positive multidrug-resistant Enterococcus faecium (VRfm), harboring ermB-1 (38.9%), esp (84%), efaA (71.2%), hyl (54.5%), asa1 (23.4%), gelE and cpd (11.6%) each. Ability of biofilm production was detected in 20.8%. Genetic relatedness of the isolates revealed 13 clusters, heterogeneous picture and 25 unique MTs profiles.

Conclusion: The obtained prevalence of VRE intestinal carriage among high-risk inpatients in Serbia is higher than the European average, with high percentage of multidrug resistance. The emergence of resistance to Q-D is of particular concern. Close monitoring of pattern of resistance and strict adherence to specific guidelines are urgently needed in Serbia.

in the immediate defense against pathogens, but also in shaping the acquired immune response.
On the other hand, antigen specific, high-affinity antibodies can affect the balance of natural
antibodies and lead to autoimmune diseases. In this study we have analyzed the changes that occur
in the IgM and IgG pool of natural antibodies after immunization with split or whole virion
influenza vaccine. For this purpose, “in-house” developed ELISAs were used. The subjects were
divided, according to the vaccination status, into those who had been immunized with the
influenza vaccine in previous years and those who had been immunized for the first time. The
analysis indicated that the pool of natural antibodies was not impaired by the immunization,
evidenced by the lack of changes in any of the groups, and that certain fluctuations were induced
in order to maintain the homeostasis of the immune system.

AB  - The MTT assay is routinely used to detect the activity of living cells. While working with Vipera ammodytes venom we detected the reduction of MTT without the presence of cells, in a concentration-dependent manner. By combining non-reducing PAGE, L-amino acid oxidase (LAAO) assays, and standard MTT assays, we established and confirmed that venom MTT reduction is catalyzed by only one enzyme, the LAAO. Even though it was previously known that the dimeric and tetrameric forms of LAAO are active, we conclude that the enzyme is also active in the monomeric form. Our results have led to the definition of a new MTT assay in a microtiter plate for in vitro testing of svLAAO activity i.e. from the venom of the V. ammodytes snake. Potentially, this method can be used for testing hemorrhagic venoms of other snakes as well as the LAAO neutralization capability of appropriate antivenoms.

AB  - The surface of microorganisms is covered with polysaccharide structures which are in immediate contact with receptor structures on host's cells and antibodies. The interaction between microorganisms and their host is dependent on surface glycosylation and in this study we have tested the interaction of plant lectins with different microorganisms. Enzyme-linked lectin sorbent assay - ELLSA was used to test the binding of recombinant Musa acuminata lectin - BL to 27 selected microorganisms and 7 other lectins were used for comparison: Soy bean agglutinin - SBA, Lens culinaris lectin - LCA, Wheat germ agglutinin - WGA, RCA(120) - Ricinus communis agglutinin, Con A - from Canavalia ensiformis, Sambucus nigra agglutinin - SNA I and Maackia amurensis agglutinin - MAA. The goal was to define the microorganisms' surface glycosylation by means of interaction with the selected plant lectins and to make a comparison with BL. Among the tested lectins most selective binding was observed for RCA(120) which preferentially bound Lactobacillus casei DG. Recombinant banana lectin showed specific binding to all of the tested fungal species. The binding of BL to Candida albicans was further tested with fluorescence microscopy and flow cytometry and it was concluded that this lectin can differentiate ss-glucan rich surfaces. The binding of BL to S. boulardii could be inhibited with ss-glucan from yeast with IC50 1.81 mu g mL(-1) and to P. roqueforti with 1.10 mu g mL(-1). This unique specificity of BL could be exploited for screening purposes and potentially for the detection of ss-glucan in solutions.
