Multiple bacteria may be behind elk hoof disease

Treponeme-associated hoof disease (TAHD) in elk is driven by a polymicrobial community rather than a single pathogen

How genes influence the microbes in our mouths

No matter how much they brush their teeth, some people still get more cavities than others, in part because of differences in genetics and the make-up

#Bacterial #plasmids utilize two distinct survival strategies—stealth and manipulation—to drive a "stealth-first" mechanism where #antimicrobial resistance genes are initially acquired by stealthy plasmids before being rapidly disseminated by manipulative ones.
