Morganella morganii strain CQ-M7

Morganella morganii strain CQ-M7 is a Gram-negative, rod-shaped bacterium classified as a facultative anaerobe, indicating its ability to grow in both the presence and absence of oxygen. This strain is mesophilic, thriving within moderate temperature ranges typical of many environmental settings. It has a single replicon, which is characteristic of many bacteria within its phylogenetic group. This bacterium is primarily found in natural environments and sewage, suggesting its association with organic matter and potential pathogens in contaminated water sources. It has been identified as a pathogen in humans, with a range of health effects that include intra-abdominal infections, wound infections, endophthalmitis, sepsis, urinary tract infections, cellulitis, post-operative wound infections, infectious ocular disease, summer diarrhea, hepatobiliary infections, abscess formation, and purple urine bag syndrome. Hosts for M. morganii strain CQ-M7 include Homo sapiens and Acanthamoeba castellanii, highlighting its adaptability and potential interactions within various ecological niches. Understanding the pathogenic potential of this strain, especially in relation to its habitat in sewage and natural environments, underscores its role in both clinical and environmental microbiology. As a clinically relevant pathogen, continuous monitoring of this organism in sewage and natural habitats may provide insights into public health risks and inform strategies for infection control.
