| Description | Aeromonas media is a gram-negative, rod-shaped bacterium that falls under the mesophilic temperature preference category, thriving optimally at 25-37 °C. This microbe is classified as a heterotroph, meaning it relies on organic compounds for its nutritional needs rather than synthesizing them from inorganic sources. Furthermore, Aeromonas media is identified as a facultative anaerobe, capable of surviving in both aerobic and anaerobic conditions, making it versatile in various environments. This bacterium is typically found in aquatic environments, including freshwater and brackish waters, as well as in the gastrointestinal tract of various hosts, including fish, amphibians, and mammals. Aeromonas media can also be isolated from soil and sediment, indicating its adaptability and resilience in different ecological niches. The ability to exist across multiple body sites reflects its ecological flexibility and potential role in the microbiome of aquatic organisms. In terms of pathogenicity, Aeromonas media is notable for its ability to cause infections in humans, particularly in immunocompromised individuals. It is associated with gastroenteritis and wound infections, highlighting its significance as both an environmental organism and a potential pathogen. Furthermore, it is known for its enzymatic capabilities, such as producing various exoenzymes that facilitate nutrient acquisition in diverse environments. The presence of Aeromonas media in aquaculture raises concerns about its role in fish diseases, which can impact fish health and aquaculture productivity. This bacterium also serves as a model organism for studying the ecology of aquatic environments and the dynamics of microbial communities in freshwater systems. |
