| Description | Aeromonas caviae is a gram-negative, rod-shaped bacterium that thrives in moderate temperatures, classifying it as a mesophile. As a chemoheterotroph, it derives energy from organic compounds, making it reliant on external sources for both carbon and energy. This versatile microbe exhibits facultative anaerobic behavior, allowing it to grow in the presence or absence of oxygen, although it prefers aerobic conditions. Aeromonas caviae is commonly found in aquatic environments, including freshwater, brackish water, and marine ecosystems. It is present in the gastrointestinal tracts of various animals, particularly in the intestines of fish and amphibians, but it is also noted in humans, where it can inhabit the gastrointestinal tract and sometimes the skin or wounds. This broad habitat range reflects its adaptability and ecological significance. In terms of pathogenicity, Aeromonas caviae can be associated with gastroenteritis, particularly in individuals with compromised immune systems or underlying health conditions. The bacterium can produce virulence factors, including enterotoxins, which contribute to its ability to cause disease. Symptoms of infection may include diarrhea, abdominal pain, and in more severe cases, septicemia. Beyond its pathogenic potential, Aeromonas caviae plays a role in wastewater treatment processes, contributing to the breakdown of organic matter. Its presence in aquatic environments can also serve as a bioindicator for assessing water quality. The organism's ability to survive in diverse habitats underscores its ecological flexibility and importance in microbial communities. |
