Serratia marcescens strain KCTC 42172 36

Serratia marcescens strain KCTC 42172 is a Gram-negative, rod-shaped bacterium characterized as a facultative anaerobe and a chemoheterotroph. This strain is motile, possessing flagella that facilitate its movement. It thrives optimally at 37°C, fitting within the mesophilic temperature range. S. marcescens strain KCTC 42172 is notable for its diverse habitat, which includes associations with various hosts such as Homo sapiens, Viridiplantae, and multiple insect species, including Apis mellifera (honey bees) and Anopheles stephensi (a malaria vector). Its pathogenicity is of particular concern in human health, as it is implicated in nosocomial infections, early onset neonatal sepsis, and white pox disease. The bacterium is nonsporulating and has a single replicon, which is typical for many members of the Enterobacteriaceae family. This genetic characteristic may influence its adaptability and survival in various environments. Understanding its ecological roles and interactions with different hosts can provide insights into its pathogenic potential and the risks it poses in clinical settings. Overall, the presence of S. marcescens in diverse ecological niches and its association with significant health issues highlight the importance of monitoring this bacterium in both healthcare and environmental contexts.
