Exploring Antibiotic Susceptibility, Resistome And Mobilome Structure Of Planctomycetes From Gemmataceae Family

The family Gemmataceae accomodates aerobic, chemoorganotrophic planctomycetes with large genome sizes, is mostly distributed in freshwater and terrestrial environments. However, these bacteria have recently also been found in locations relevant to human health. Since the antimicrobial resistance genes (AMR) from environmental resistome have the potential to be transferred to pathogens, it is essential to explore the resistant capabilities of environmental bacteria. In this study, the reconstruction of in silico resistome was performed for all nine available gemmata genomes. Furthermore, the genome of the newly isolated yet-undescribed strain G18 was sequenced and added to all analyses steps. Selected genomes were screened for the presence of mobile genetic elements. The flanking location of mobilizable genomic milieu around the AMR genes was of particular interest since such colocalization may appear to promote the horizontal gene transfer (HGT) events. Moreover the antibiotic susceptibility profile of six phylogenetically distinct strains of Gemmataceae planctomycetes was determined.
