Secretion of Yop proteins by Yersiniae.
Yersinia enterocolitica Abstract: Upon incubation at 37 degrees C in the absence of Ca2+ ions, pathogenic strains of the genus Yersinia cease growing and produce large amounts of a series of plasmid-encoded ...
Dietary silver nanoparticles can disturb the gut microbiota in mice.
NP-supplemented pellets showed that freshly prepared pellets released Ag ions faster than aged pellets. STEM- EDX analysis also showed that Ag sulfidation occurred in aged Ag NP-supplemented pellets. CONCLUSIONS: ...
