Escherichia coli strain PNUSAE019581

Escherichia coli strain PNUSAE019581 is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as single cells. This strain thrives optimally at a temperature of 37.0°C, which aligns with the normal body temperature of many warm-blooded hosts, suggesting its adaptation to a host-associated habitat. As a facultative anaerobe, E. coli strain PNUSAE019581 can grow in both the presence and absence of oxygen, allowing it to occupy diverse environments within the gastrointestinal tract of its hosts. The ability to thrive in variable oxygen conditions may confer an ecological advantage, enabling this strain to adapt to different niches within the host. Furthermore, the association with host organisms indicates a likely role in the complex microbiota, where it may contribute to nutrient processing and maintenance of gut health. This adaptability and its specific habitat preference highlight the importance of E. coli strain PNUSAE019581 in the broader context of microbial ecology and host interactions.
