| Description | Yersinia rohdei is a Gram-negative, rod-shaped bacterium that thrives at mesophilic temperatures, categorizing it as a facultative anaerobe and a chemoheterotroph. This microbe is part of the Yersinia genus, which includes several well-known pathogens, though Y. rohdei is less commonly discussed. It is typically found in various body sites of both humans and animals, particularly in the gastrointestinal tract and the environment, where it may colonize different flora. As a Gram-negative organism, Y. rohdei possesses a thin peptidoglycan layer surrounded by an outer membrane containing lipopolysaccharides, contributing to its virulence and resistance to certain antibiotics. The rod shape enhances its motility and ability to invade host tissues. Being mesophilic, it prefers moderate temperatures, generally ranging from 20°C to 37°C, making it suitable for colonization in warm-blooded hosts. Y. rohdei is classified as a facultative anaerobe, meaning it can survive both in the presence and absence of oxygen. This adaptability allows it to thrive in various environments, including the oxygen-rich gut and anaerobic conditions found in certain tissues. As a chemoheterotroph, it relies on organic compounds for energy and carbon, obtaining nutrients from the host's diet or surrounding environment.Notably, Yersinia rohdei has been studied for its environmental resilience and potential role in the ecology of intestinal microbiomes. Its interactions with other gut biota and the human host's immune system offer insights into the complexity of microbial communities and their impact on health. Moreover, this microbe is of interest in research on emerging infectious diseases, as its genetic makeup suggests the potential for pathogenicity under certain conditions. |
