AB  - We tested the effects of early‐life probiotic treatment on the induction of colitis in female and male adult rats. Rat pups were fed an aqueous solution of Lactobacillus rhamnosus (from 
day 4  to day 30). Feces were collected  for microbial analysis. Colitis was induced at day 85. Seven days later  rats were graded  for histological damage in colon, and samples of 
mesenteric lymph node (MLN) and peritoneal exudate cells were analyzed. Female rats developed slightly less severe symptoms of colitis than males, whereas early‐life probiotic 
treatment had a more pronounced effect on males in nearly every analyzed parameter. Namely, it increased fecal bacterial diversity and ameliorated colon tissue damage, as well 
as increased percentage of resident peritoneal macrophages (CD163+), decreased peritoneal monocyte (HIS48+CD43+) influx, reduced production of IFNγ and IL10 by MLN cells, 
attenuated NO production in stimulated peritoneal macrophages and unstimulated MLN cells of male rats. Our findings reveal that effects of probiotic treatment are sex‐specific to an 
extent. While microbial diversity was impacted by probiotic treatment in both sexes at an early age, the effect was more pronounced in young males, and it lasted to their adulthood. 
The change in microbial diversity correlated with improved outcome of TNBS‐induced colitis, confirming the importance of microbiota for local inflammatory processes. It remains to 
be elucidated whether the sex differences in the effect of probiotic treatment on development of colitis may be a consequence of sex differences in early‐life microbial diversity and 
severity of colitis symptoms in untreated rats.

AB  - The aim of this review was to summarize the data regarding diversity of non-starter lactic acid bacteria (NSLAB) isolated from various artisanal dairy products manufactured in Western Balkan Countries. The dairy products examined were manufactured from raw cow's, sheep's or goat's milk or mixed milk, in the traditional way without the addition of commercial starter cultures. Dairy products such as white brined cheese, fresh cheese, hard cheese, yogurt, sour cream and kajmak were sampled in the households of Serbia, Croatia, Slovenia, Bosnia and Herzegovina, Montenegro, and North Macedonia. It has been established that the diversity of lactic acid bacteria (LAB) from raw milk artisanal dairy products is extensive. In the reviewed literature, 28 LAB species and a large number of strains belonging to the Lactobacillus, Lactococcus, Enterococcus, Streptococcus, Pediococcus, Leuconostoc and Weissella genera were isolated from various dairy products. Over 3000 LAB strains were obtained and characterized for their technological and probiotic properties including: acidification and coagulation of milk, production of aromatic compounds, proteolytic activity, bacteriocins production and competitive exclusion of pathogens, production of exopolysaccharides, aggregation ability and immunomodulatory effect. Results show that many of the isolated NSLAB strains had one, two or more of the properties mentioned. The data presented emphasize the importance of artisanal products as a valuable source of NSLAB with unique technological and probiotic features important both as a base for scientific research as well as for designing novel starter cultures for functional dairy food.

AB  - The current study investigated a potential modulating effect of orally applied Lactobacillus rhamnosus 64 (LB64) during the early postnatal period (day of life: similar to 3-30), during young adult period (day of life: 31-70) or throughout experiment, on parameters of trinitrobenzenesulfonic acid (TNBS)-induced colitis in adult rats. Treatment with LB64 during early postnatal, but not during young adult period reduced clinical damage score, neutrophil and macrophage infiltration into colon, the level of cytokine and myeloperoxidase (MPO) activity, but had no influence on other parameters of oxidative damage. Early postnatal treatment with LB64 also increased the diversity of fecal Bifidobacteria and Eubacteria, and improved maturation of ileal villi in 30-days old rats. When LB64 is applied during a critical period early in life, it affects immune system functioning of adults, probably by interactions with the mucosal immune system of the gastrointestinal tract that provides immune system maturation and shapes the overall immune response.

AB  - Despite the number of studies on antibiotic-resistant enterococci from Serbian clinical settings, there are no data about environmental contamination with these bacteria. Thus, this study investigated the prevalence of antibiotic-resistant enterococci in Belgrade, Serbia. Enterococcus species collected from ten surface water sites, including a lake, two major river systems, and springs, were tested. Among enterococci, we found single (21.7 %), double (17.4 %), and multiple antibiotic resistance patterns (56.3 %). Vancomycin-resistant strains were not found, indicating that their abundance in Belgrade is tightly linked to clinical settings. The multiple drug-resistant strains Enterococcus faecalis, Enterococcus faecium, and Enterococcus mundtii were frequently detected in the lake during the swimming season and in the rivers near industrial zones. We confirmed the presence of ermB, ermC, ant(6)-Ia, tetM, and tetL and mutations in gyrA genes. The phylogenetic analysis of 16S rRNA gene of E. faecium isolates that harbor esp gene classified them into two groups based on high-bootstraps scores in the tree analysis. Pulsed-field gel electrophoresis analysis of antibiotic-resistant enterococci revealed genomic similarity ranging from 75 to 100 %. This study indicates the importance of anthropogenic impact to the spread of antibiotic-resistant enterococci in environmental waters of Belgrade, Serbia.

AB  - In order to preserve the traditional manufacturing of white pickled (WPC) and fresh soft cheeses (FSC), well-characterized autochthonous lactic acid bacteria (LAB) with advantageous characteristics were applied for the production of the cheeses at small industrial scale under the controlled conditions. Selected LAB for design of defined mixed starter cultures belonged to Lactococcus lactis ZGBP5-9, Enterococcus faecium ZGPR1-54 and Lactobacillus plantarum ZGPR2-25 for FSC production and to Lc. lactis BGAL1-4, Lactobacillus brevis BGGO7-28 and Lb. plantarum BGGO7-29 for WPC production. A sensory evaluation indicated that the cheeses obtained by inoculation with selected autochthonous LAB are similar to the traditional cheese and received the best scores. Viable cell counts of LAB used for the production of both type chesses was high, over 10(6) cfu g(-1). High viability of the surveyed strains was supported with PCR-DGGE, which confirm the retention of selected LAB strains as starter cultures in cheese production. Next, PFGE analysis showed that each single strains, selected in particular cheese mixed culture, revealed unique SmaI PFGE pattern that could enable efficient discrimination and monitoring of the strains in industrial process. As some of the selected LAB strains are attributed as potential probiotics, produced cheeses could be considered as functional food.

AB  - Enterococci represent the most controversial group of dairy bacteria. They are found to be the main constituent of many traditional Mediterranean dairy products and contribute to their characteristic taste and flavor. On the other hand, during the last 50 years antibiotic resistant enterococci have emerged as leading causes of nosocomial infections worldwide. The aim of this study was to determine the diversity, technological properties, antibiotic susceptibility and virulence traits of 636 enterococci previously isolated from 55 artisan dairy products from 12 locations in the Western Balkan countries (WBC) of Serbia, Croatia and Bosnia and Herzegovina. All strains were identified both by microbiological and molecular methods. The predominant species was Enterococcus durans, followed by Enterococcus faecalis and Enterococcus faecium. Over 44% of the isolates were resistant to ciprofloxacin and erythromycin, while 26.2% of the isolates were multi resistant to three or more antibiotics belonging to different families. 185 isolates (29.1%) were susceptible to all 13 of the antibiotics tested. The antibiotic-susceptible isolates were further tested for possible virulence genes and the production of biogenic amines. Finally, five enterococci isolates were found to be antibiotic susceptible with good technological characteristics and without virulence traits or the ability to produce biogenic amines, making them possible candidates for biotechnological application as starter cultures in the dairy industry.

AB  - The aim of this study was to investigate the composition of lactic acid bacteria (LAB) in autochthonous young cheeses, sweet creams and sweet kajmaks produced in the Vlasic mountain region of central Bosnia and Herzegovina near the town of Travnik over a four season period. These three products were made from cow's milk by a traditional method without the addition of a starter culture. Preliminary characterization with phenotype-based assays and identification using rep-PCR with a (GTG)(5) primer and 16S rDNA sequence analysis were undertaken for 460 LAB isolates obtained from all the examined samples. Fifteen species were identified as follows: Lactococcus lactis, Lactococcus raffinolactis, Lactococcus garviae, Lactobacillus casei, Lactobacillus plantarum, Lactobacillus helveticus, Enterococcus faecium, Enterococcus durans, Enterococcus faecalis, Enterococcus italicus, Leuconostoc mesenteroides, Leuconostoc pseudomesenteroides, Leuconostoc lactis, Streptococcus thermophilus and Streptococcus mitis. A wide genotypic and phenotypic heterogeneity of the species was observed, particularly within the Lc. lactis strains. In all of the tested dairy products across four seasons, a significantly positive correlation (r = 0.690) between the presence of lactococci and enterococci and a negative correlation (r = 0.722) between the presence of lactococci and leuconostocs were recorded. Forty-five percent of the lactobacilli and 54.4% of the lactococci exhibited proteolytic activity, whereas 18.7% of the total LAB isolates exhibited antimicrobial activity.

AB  - Soj Enterococcus faecalis BGPT1-10P je izolovan iz domaćeg polutvrdog sira, poreklom sa Stare Planine. Rezultati pokazuju da soj BGPT1-10P sintetiše termolabilan bakteriocin, enterolizin A, sa širokim spektrom delovanja, uključujući patogene bakterije roda Listeria i Candida. EntL gen, odgovoran za sintezu ovog bakteriocina, je hromozomalno lokalizovan. Analiza nukleotidne sekvence entL gena kod prirodnog izolata En. faecalis BGPT1-10P je identična sa entL genom soja En. faecalis LMG 2333, koji je prethodno okarakterisan. Pokazana je jedinstvena sekvenca entL gena i njegove okoline, koju čine orf1, orf2 i orf3 geni, kao i scpE gen. Prvi put je kod prirodnog izolata okarakterisan scpE gen, koji kodira virulentni faktor stafopain peptidazu. Funkcionalna analiza entL gena je pokazala da je kompletna genetička informacija, neophodna za sintezu i aktivnost enterolizina A, sadržana u entL genu. Soj BGPT1-10P osim enterolizina, sintetiše i želatinazu i citolizin i sadrži set različitih virulentnih faktora. Pored toga, BGPT1-10P nosi ermB i tetM gene, odgovorne za rezistenciju na eritromicin i tetraciklin.
AB  - Strain Enterococcus faecalis BGPT1-10P was isolated from artisanal semi-hard homemade cheese from Stara Planina, Serbia. Results showed that BGPT1-10P synthesized a heat labile bacteriocin with a broad spectrum of activity, including Listeria and Candida species. Further analysis revealed that synthesized bacteriocin is enterolysin A. Moreover, the entL gene encoding enterolysin A was found to be located on the chromosome. The entL gene was cloned and sequenced. Analysis of nucleotide sequence showed that the entL gene in natural isolate En. faecalis BGPT1-10P is identical to that of the entL gene described previously in En. faecalis LMG 2333. Within the cloned DNA fragment containing the entL gene, four ORFs were detected. One of them was identified as the scpE gene, which encodes a virulent factor staphopain peptidase. Functional analysis of the entL gene showed that the complete genetic information necessary for the synthesis of enterolysin A were directly linked solely to it. Strain BGPT1-10P also synthesized gelatinase and citolysin, and contained a set of virulent factors. In addition, BGPT1-10P carries the ermB and tetM genes conferring the resistance to erythromycin and tetracycline, respectively.

AB  - Staphylococcus epidermidis strains were isolated from the expressed human breast milk (EHM) of 14 healthy donor mothers. Genetic diversity was evaluated using RAPD-PCR REP-PCR and pulse-field gel electrophoresis (PFGE). PFGE allowed the best discrimination of the isolates, since it provided for the greatest diversity of the analyzed genomes. Among the S. epidermidis strains, resistance to gentamicin, tetracycline, erythromycin, clindamycin or vancomycin was detected, whilst four isolates were multiresistant. The results from our study demonstrate that staphylococci from EHM could be reservoirs of resistance genes, since we showed that tetK could be transferred from EHM staphylococci to Gram-negative Escherichia coli. Most of the staphylococcal strains displayed excellent proteolytic and lipolytic activities. Additionally, the presence of ica genes, which was related to their ability to form a biofilm on tissue culture plates, and the presence of virulence factors including autolysin/adhesin AtLE, point to their pathogenic potential.

Genski klaster bacSJ2-8/bacSJ2-8i prisutan je kod 49 (94.23%), a acdT kod 41 (78.85%) od 52 testirana soja. Četrdeset sojeva (76.92%) poseduje oba analizirana gena. Interesantno je da samo 17 sojeva (32.69%) koji poseduju bacSJ2-8/bacSJ2-8i genski klaster i/ili acdT gen proizvode bakteriocine. Soj L. paracasei BGNK1-62 poseduje bacSJ2-8/bacSJ2-8i genski klaster, ali ne proizvodi bakteriocin BacSJ što je verovatno posledica nedostatka abcT i acc gena. Nakon transformacije soja BGNK1-62 konstruktom pA2A koji poseduje abcT i acc gene ostvarena je proizvodnja bakteriocina BacSJ. Osim toga, utvrđeno je da soj L. paracasei BGGR2-66 proizvodi nov bakteriocin označen kao BacGR, koji je biohemijski okarakterisan, a određena je i njegova N-terminalna sekvenca.
AB  - The aim of this study was to investigate the antimicrobial potential of 52 natural isolates of Lactobacillus casei/paracasei. The incidence of relevant genes encoding BacSJ (bacSJ2-8/bacSJ2-8i gene cluster), acidocin 8912 (acdT), ABC-transporter (abcT) and accessory protein (acc) was also studied. These genes were found to be widespread amongst the analyzed L. casei/paracasei strains. The bacSJ2-8/bacSJ2-8i gene cluster was present in 49 (94.23%) and acdT in 41 (78.85%) of the 52 tested strains. Forty of these strains (76.92%) harbored both analyzed genes. Interestingly, only 17 strains (32.69%) with the bacSJ2-8/bacSJ2-8i gene cluster and/or the acdT gene showed bacteriocin production. Strain L. paracasei BGNK1-62 contained the bacSJ2-8/bacSJ2-8i gene cluster, but did not produce bacteriocin BacSJ possibly due to absence of the abcT and acc genes. Hence, these genes were introduced into BGNK1-62 by transformation with constructed plasmid pA2A, after which BacSJ was produced. In addition, it was found that L. paracasei BGGR2-66 produced new bacteriocin designated as BacGR that was biochemically characterized and its N- terminal sequence was determined.

AB  - Background: Aggregation may play a main role in the adhesion of bacteria to the gastrointestinal epithelium and their colonization ability, as well as in probiotic effects through co-aggregation with intestinal pathogens and their subsequent removal. The aggregation phenomenon in lactococci is directly associated with the sex factor and lactose plasmid co-integration event or duplication of the cell wall spanning (CWS) domain of PrtP proteinase. Results: Lactococcus lactis subsp. lactis BGKP1 was isolated from artisanal semi-hard homemade cheese and selected due to its strong auto-aggregation phenotype. Subsequently, non-aggregating derivative (Agg(-)) of BGKP1, designated as BGKP1-20, was isolated, too. Comparative analysis of cell surface proteins of BGKP1 and derivative BGKP1-20 revealed a protein of approximately 200 kDa only in the parental strain BGKP1. The gene involved in aggregation (aggL) was mapped on plasmid pKP1 (16.2 kb), cloned and expressed in homologous and heterologous lactococci and enterococci. This novel lactococcal aggregation protein was shown to be sufficient for cell aggregation in all tested hosts. In addition to the aggL gene, six more ORFs involved in replication (repB and repX), restriction and modification (hsdS), transposition (tnp) and possible interaction with mucin (mbpL) were also located on plasmid pKP1. Conclusion: AggL is a new protein belonging to the collagen-binding superfamily of proteins and is sufficient for cell aggregation in lactococci.

AB  - A collection of 25 isolates from foods of animal origin (including mainly milk and cheese, together with meat and ham) was studied. Enterococci were identified at species levels as E. faecalis (9 isolates) and E. faecium (16 isolates). Investigation of virulence factors by PCR amplification revealed incomplete sets of cytolysin genes both in E faecalis and E. faecium isolates. Among E. faecalis, PCR amplification revealed a high incidence of genes encoding for enterococcal surface protein esp (7/9 isolates), enterococcal antigen efaA(fs) (6/9), aggregation substance agg (2/9) and sex-pheromone encoding genes ccf, cob, cpd (which were detected in 9, 5 and 3 out of 9 isolates, respectively). By contrast, only esp (7/16 isolates) and efaA(fm) (10/16) were detected among E.faecium. Antibiotic resistance detected at higher frequencies included rifampicin, nitrofurantoin, ciprofloxacin and levofloxacin. Vancomycin resistance was also detected among E.faecalis and E.faecium. E.faecalis isolates showed decarboxylating activity mostly for tyrosine (5/9 isolates), while E faecium isolates showed a broader decarboxylating capacity, involving tyrosine (11/16 isolates) ornithine (6/16), lysine (4/16) and histidine (3/16). Six isolates produced bacteriocins, and genes encoding for enterocins A, B, P, L50, and 1071 were detected. Many isolates tested positive for several of the traits investigated, which raises concerns about their possible role as reservoirs for dissemination of antibiotic resistance and virulence traits in foods.

In total, 253 Gram-positive and catalase negative lactic acid bacteria (LAB) were isolated. Results showed that 70 out of 253 analyzed isolates produced antimicrobial compounds known as bacteriocins. Most isolates from genera Lactococcus and Enterococcus, and isolates belonging to species Lactobacillus plantarum and Lb. brevis, do not synthesize extracellular proteinase. In contrast, isolates from subspecies Lb. paracasei subsp. paracasei showed very good proteolytic activity. It was observed that good proteolytic activity of isolates was not in correlation with their good antimicrobial activity in the most of isolates.
