Aeromonas hydrophila strain GSH8-2

Aeromonas hydrophila strain GSH8-2 is a gram-negative, rod-shaped bacterium that exhibits a versatile lifestyle as a facultative aerobe and heterotroph. It typically exists in various habitats, demonstrating its adaptability to multiple environmental conditions. The cells can be found in chains, pairs, or singles, and the organism possesses flagella, which contribute to its mobility. This strain thrives optimally at a temperature of 22°C, categorizing it as mesophilic, with the ability to grow across a range of temperatures. A notable feature of Aeromonas hydrophila GSH8-2 is its free-living biotic relationship, enabling it to survive independently without a host. The strain is associated with a wide variety of hosts, including Homo sapiens, various species of fish (such as Oreochromis niloticus and Ictalurus punctatus), insects (like Culex pipiens pallens and Aedes aegypti), as well as amphibians and other vertebrates. This broad host range is significant as it highlights the potential for this bacterium to impact diverse ecosystems and species. Aeromonas hydrophila GSH8-2 is clinically relevant, with documented health effects including meningitis, necrotizing fasciitis, and a range of gastrointestinal and respiratory infections. The presence of this bacterium in both aquatic and terrestrial environments underscores its ecological significance and potential public health implications, particularly in areas where humans and aquatic organisms interact closely.
