Whole genome analyses of toxicants tolerance genes of Apis mellifera gut-derived Enterococcus faecium strains.

ABSTRACT:

Background

Because of its social nature, the honeybee is regularly exposed to environmental toxicants such as heavy metals and xenobiotics. These toxicants are known to exert strong selective pressure on the gut microbiome's structure and diversity. For example, resistant microbial members are more likely to dominate in maintaining a stable microbiome, which is critical for bee health. Therefore, the aim of this study was to examine the Enterococcus faecium strains isolated from bee guts for their in vitro growth and tolerability to diverse heavy metals and xenobiotics. An additional aim was to analyze the genomes of E. faecium isolates to assess the molecular bases of resistance and compare them with E. faecium species isolated from other environmental sources.
