Escherichia coli O104:H4 str. 2011C-3493

Escherichia coli O104:H4 str. 2011C-3493 is a Gram-negative, rod-shaped bacterium that typically occurs in pairs or as single cells. This strain thrives at an optimal temperature of 37.0°C, which corresponds to the human body temperature, suggesting its adaptation to host-associated environments. As a facultative anaerobe, E. coli O104:H4 str. 2011C-3493 can grow in both aerobic and anaerobic conditions, allowing it to exploit a variety of ecological niches within the host, such as the intestinal tract. The association of this strain with host environments highlights its potential interactions with the host's microbiome and immune system. Given its capabilities, E. coli O104:H4 str. 2011C-3493 may play a role in nutrient absorption and microbial competition within the gastrointestinal tract, contributing to the complex dynamics of gut microbiota. Understanding its growth characteristics and habitat preferences can provide insights into the ecological roles of E. coli in health and disease contexts.
