Whole-genome analysis of the colonization-resistant bacterium Phytobacter sp. SCO41T isolated from Bacillus nematocida B16-fed adult Caenorhabditis elegans.

Colonization resistance is an important attribute for bacterial interactions with hosts, but the mechanism is still not completely clear. In this study, we found that Phytobacter sp. SCO41T can effectively inhibit the in vivo colonization of Bacillus nematocida B16 in Caenorhabditis elegans, and we revealed the colonization resistance mechanism. Three strains of colonization-resistant bacteria, SCO41T, BX15, and BC7, were isolated from the intestines of the free-living nematode C. elegans derived from rotten fruit and soil. The primary characteristics and genome map of one of the three isolates was investigated to explore the underlying mechanism of colonization resistance in C. elegans.…
