Preferential Packing of Acidic Glycosidases and Proteases into
mBio, 2014 Outer membrane vesicles (OMV) are spherical membranous structures released from the outer membrane (OM) of Gram-negative bacteria. OMV have been proposed to play several different roles during both pathogenesis and symbiosis.

Integrative Zoology, EarlyView.Host species emerge as a significant contributor to interspecies variations in the gut microbiota of desert‐dwelling amphibians and reptiles, illustrating phylosymbiosis among the studied species. Geographical factors partially account for interpopulation variations in the gut microbiota of Bufotes pewzowi and Teratoscincus przewalskii, with parallel ...

The search for conjugative transposon in rumen bacterium Prevotella bryantii B14
Acta Agriculturae Slovenica, 2009 Only few plasmids and bacteriophages have been described to date in ruminal prevotella strains, therefore it appears plausible that the genetic exchange in these organisms must exploit other routes.

Molecular Microbiology, EarlyView.A novel TetR‐like regulator (EppR) has been identified to repress genes encoding DNA polymerase V in Acinetobacter baumannii through the direct binding of a conserved EppR motif in their promoters. EppR works with previously identified regulator UmuDAb to serve as co‐regulators of these genes. In response to DNA damage and/or environmental stress, both
