Escherichia coli O83:H1 str. NRG 857C

Escherichia coli O83:H1 str. NRG 857C is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as single cells. It is a facultative anaerobe, indicating its ability to thrive in both aerobic and anaerobic environments, and it has an optimal growth temperature of 37.0°C, which is consistent with the physiological temperature of the human body. This microbe is primarily host-associated, suggesting that it is commonly found in association with animal hosts, potentially within the gastrointestinal tract. The facultative anaerobic nature of E. coli O83:H1 str. NRG 857C allows it to adapt to varying oxygen levels in its habitat, which is crucial for survival in diverse environments encountered within a host. This adaptability may also confer advantages in competitive interactions with other microbial communities in the gut. Understanding the growth conditions and habitat preferences of this strain can provide insights into its ecological roles, including its potential contributions to gut microbiota composition and function. Additionally, the ability to grow optimally at 37.0°C indicates a specialization for life within warm-blooded hosts, emphasizing its potential interactions with host biology. Further research into this strain may unveil additional ecological or physiological characteristics that could illuminate its role in host-associated environments.
