The human vaginal microbiome, particularly its symbiosis with lactobacilli, plays a key role in maintaining women’s health. While lactic acid-mediated pathogen exclusion is well known, broader metabolic functions of vaginal lactobacilli remain underexplored. In this study, we analyzed the vaginal...
Depletion of gut commensal bacteria significantly reduced nicotinic acid (NA) levels in the hemolymph and ovaries of Bactrocera dorsalis, leading to impaired ovarian development. This inhibition was reversed by exogenous NA supplementation. We identified Enterobacter hormaechei as a key NA-produc...
The protection of associated microbiota for their animal hosts against pathogen infection has been studied widely over the last 100 years. However, how those microbes protect the animal host is limitedly investigated. In former studies, body surface microbes of one insect, Delia antiqua,...
