Escherichia coli 113303

Escherichia coli 113303 is a Gram-negative, rod-shaped bacterium that exhibits a cell arrangement primarily in pairs and singles. This strain thrives optimally at 37.0°C, reflecting its adaptation to a host-associated habitat, which is typical for many members of the Escherichia genus. As a facultative anaerobe, E. coli 113303 can grow in both aerobic and anaerobic environments, allowing it to exploit diverse ecological niches within the host. The ability to switch between aerobic respiration and fermentation pathways is a significant metabolic advantage, facilitating survival in fluctuating oxygen conditions typically found in the intestinal tract of hosts. Furthermore, this adaptability may also play a role in the microbe's interactions with the host's immune system and other microbial inhabitants of the gut. Understanding such traits enables researchers to better appreciate the ecological roles of E. coli strains like 113303 in host-associated environments, as they may contribute to nutrient cycling and influence the overall microbiome composition.
