Listeria monocytogenes M7

Listeria monocytogenes M7 is a Gram-positive, rod-shaped bacterium that primarily exists in various habitats, indicating its adaptability to multiple environments. It is classified as a chemoorganotroph, meaning it derives its energy from organic compounds. This organism functions as a facultative anaerobe, allowing it to survive in both the presence and absence of oxygen. In terms of cellular arrangement, Listeria monocytogenes M7 typically forms chains or singles, which reflects its characteristic growth pattern. The bacterium is non-motile despite the presence of flagella, suggesting that while it has the potential for movement, it does not utilize this capability in its ecological niche. With an optimal growth temperature of 30°C, Listeria monocytogenes M7 is categorized as mesophilic, thriving in moderate temperature ranges. It has a single replicon and one membrane, which is typical for its classification within the genus Listeria. The organism has a free-living biotic relationship, indicating it does not rely on a host for survival. An ecological insight regarding Listeria monocytogenes M7 is its ability to adapt to diverse environments, which may contribute to its role in various foodborne illnesses. Its survival strategies and metabolic versatility underscore the significance of monitoring this bacterium in food safety and public health contexts. This adaptability enhances its potential for persistence in contaminated food products, raising concerns for food safety authorities. The accession number for further genomic information is NC_017537.1.
