Wallis CV, et al. - Researchers sought to understand the degree of conservation in phenotypic characteristics of salmonellae isolates across host species. In pathogenic Salmonella isolated from humans and dogs, differential carbon source utilisation and antimicrobial sensitivity profiles were noticed, suggesting distinct reservoirs of infection for these hosts. Despite these findings not precluding zoonotic or anthroponotic potential in salmonellae, the separation of carbon utilisation and antibiotic profiles with isolate source was suggestive that infectious isolates were not part of a common reservoir shared frequently between these host species.
