Escherichia coli strain SD134209

Escherichia coli strain SD134209 is a Gram-negative, rod-shaped bacterium characterized by its mobility and the presence of flagella. This strain is classified as a facultative anaerobe, indicating its ability to thrive in both aerobic and anaerobic environments. It typically resides in host-associated habitats, where it can be found in pairs or as single cells. The optimal growth temperature for this mesophilic organism is 37°C. Strain SD134209 is notable for its extensive range of hosts, which includes Homo sapiens, various livestock such as Bos taurus and Sus scrofa, as well as numerous other vertebrates and invertebrates, including Acanthamoeba and Apis mellifera. This diverse host range highlights its adaptability and potential ecological significance. The strain is associated with a variety of health impacts, particularly in humans, where it is known to cause urinary tract infections (UTIs), gastrointestinal infections, and more severe conditions such as neonatal meningitis and hemolytic uremic syndrome (HUS). These health effects underscore the strain's pathogenicity and its potential to contribute to foodborne illnesses and nosocomial infections. The presence of strain SD134209 in multiple hosts suggests a complex interaction within ecosystems, where it may play roles in both health and disease. Its pathogenic capabilities, particularly in human hosts, emphasize the need for continued surveillance and research to understand its behavior in different environments and its implications for public health.
