Plesiomonas shigelloides strain MS-17-188

Plesiomonas shigelloides strain MS-17-188 is a Gram-negative, aerobic bacterium with a vibrio shape. This strain is classified as a chemoheterotroph, indicating that it derives energy from organic compounds. It is motile, possessing flagella that enable movement, which is essential for its ecological interactions. The optimal growth temperature for strain MS-17-188 is 30°C, placing it within the mesophilic temperature range. This suggests that it thrives in moderate temperature environments, which may be reflective of its natural habitats. Strain MS-17-188 has three replicons, indicating a complex genomic structure that could support various metabolic capabilities or adaptations. Its primary host is catfish, suggesting a potential ecological role in aquatic environments where these fish are present. Notably, Plesiomonas shigelloides is nonsporulating, which means it does not form spores as a means of survival under adverse conditions. This trait may limit its resilience compared to sporulating bacteria but highlights its dependence on specific environmental conditions for survival and reproduction. Ecologically, the presence of Plesiomonas shigelloides in catfish habitats may influence microbial community dynamics and nutrient cycling within these aquatic ecosystems. Its role as a chemoheterotroph could also affect the decomposition processes and interactions within the food web, particularly in environments where it serves as a pathogen or symbiont.
