Aeromonas salmonicida subsp. salmonicida strain M16474-11

Aeromonas salmonicida subsp. salmonicida strain M16474-11 is a Gram-negative, rod-shaped bacterium that thrives in aquatic environments. This organism is classified as a facultative anaerobe, allowing it to adapt to varying oxygen levels while utilizing organic compounds as a heterotrophic energy source. It possesses flagella, contributing to its mobility in water. The strain M16474-11 is mesophilic, indicating it flourishes within a moderate temperature range, which is typical for many aquatic bacteria. Its cellular structure includes two membranes and a single replicon, characteristic of the Proteobacteria phylum to which it belongs. This bacterium exists as a free-living organism in aquatic habitats and has been associated with several host species, including Oncorhynchus mykiss (rainbow trout), Scophthalmus maximus (flatfish), and Anguilla japonica (Japanese eel). Its presence in these host species suggests a potential role in aquatic ecosystems, possibly influencing fish health and dynamics within food webs. The strain's ecological significance may be linked to its interactions with both the environment and aquatic organisms, indicating its importance in nutrient cycling and the microbial community structure in freshwater and marine systems. Understanding its behavior and interactions can provide insights into the ecological balance in aquatic habitats, particularly in relation to fish populations and their health.
