AB  - Introduction: Brevibacillus laterosporus is a promising microbiological agent that can be used to prevent and control destructive diseases affecting honey bee colonies. In the presentstudy, the short-termeffect of the B. laterosporus BGSP11 bee diet on microbiota and mycobiota was investigated.Methods: The honey bee diet was supplemented with spores of B. laterosporus BGSP11 at a concentration of 1×108 CFU/mL in sucrose solution. Metabarcoding analysis of the bee microbial community profile was performed based on 16S RNA (bacteriobiota) and Internally Transcribes Spacer (ITS) region(mycobiota) obtained using MiSeq Illumina sequencing. The QIIME2 v2021.4 pipeline was used to analyze the obtained amplicon data library.Results: The results show that the BGSP11 bee diet slightly altered the bee microbiota and did not leadto potentially harmful changes in the bacterial microbiota. Moreover, it can potentially induce positivechanges, mainly reflected in the reduction of opportunistic bacteria. On the other hand, the treatmenthad a greater effect on mycobiota. However, the changesin the bee mycobiome caused by the treatmentcannot be considered a priori as beneficial or harmful,since the interaction between the bee and its mycobiome is not sufficiently studied. The observed positive changes in the bee mycobiome are mainlyreflected in the reduction of phytopathogenic fungi that may affect the organoleptic and techno-functional properties of honey.Conclusion: This pilot study suggests that the introduction of BGSP11 in beekeeping practice as a biological agent could be considered due to no harmful effects observed on the microbiota of bees.

AB  - Among them, bacterial and fungal pathogens Paenibacillus larvae, Melissococcus pluton, Ascosphera apis andNosema ceranae play a major impact on honey bees colonies. Thus, developing alternative prophylactic andcurative strategies are urgently needed. The use of probiotic bacteria in honey bee supplemental feeding istherefore promising to treat or prevent diseases. Brevibacillus laterosporus, Gram-positive endospore formingbacilli, is recognised as one of the promising antibacterial and antifungal agents producer.The aim of this study was to examine the short-therm effects of B. laterosporus supplemented diet on workerhoney bee microbiome.Dry spores of B. laterosporus strain BGSP11 have been administrated through a sugar syrup diet to tencolonies and a representative specimen of worker honey bees was taken before the start of the treatmentand immediately after the syrup was consumed. The microbial diversity was assessed before and after thetreatment using Illumina MiSeq sequencing platforms (ID Genomics service, Seattle, WA, USA). 16s rRNAsequencing for bacterial community profiling and fungal Internally Transcribes Spacer for mycological taxaprofiling were used. The next-generation microbiome bioinformatics platform QIIME2 v 2021.4 was used forfiltering and denoising obtained sequences, calculation of diversity metrics and taxonomy assignment. Thefeature classifier was trained using the Greengenes v 13_8 for bacterial taxa and fungal UNITE database v 8.3.The results obtained in this study indicated statisticaly significant alfa diversity between control and experimentalgroup honey bee microbiota composition. The diversity abundance was higher in control comparingto the group treated with B. laterosporus strain BGSP11 spores. There was no significant diference in Bray-Curtis distance among two groups of analysed samples. Regarding to mycological abundance, compositionwas completely different between two groups; control group had Claviceps as predominant genus, while intreated group of honey bee microbiome Metschnikowia genus was prevalent, indicating that the presence offungal pathogens in treated group is highly diminished.
