Aeromonas is a genus of bacteria commonly found in freshwater environments, such as rivers and lakes. These bacteria are rod-shaped and can thrive in various temperatures, making them adaptable to different habitats. Some species of Aeromonas are known to cause infections in humans, particularly in those with weakened immune systems. Infections caused by Aeromonas can lead to gastrointestinal issues, skin infections, and, in rare cases, more severe conditions. The bacteria can enter the body through contaminated water or food, highlighting the importance of proper hygiene and sanitation practices to prevent exposure.
