Abstract
Bacteroides spp. are prominent gut commensals that are believed to modulate the intestinal environment, in part, by producing outer membrane vesicles (OMVs). Bacteroides OMVs have been ascribed many functions in vitro, but the genetic underpinnings behind OMV biogenesis and regulation are unclear. Understanding the mechanismof OMV biogenesis is required to determine the importance of Bacteroides OMVs in vivo. Here, we describe our methodologyfor screening Bacteroides thetaiotaomicron VPI-5482 to identify genes required for OMV biogenesis and regulation in a high-throughput format. This protocol is easily adaptable and can potentially be employed to further our knowledge of OMV biogenesis in other bacteria.
