Aeromonas hydrophila is a member of the Aeromonadaceae family and is found all over the world. It may be separated from a variety of environmental sources, including aquatic environments, fish, and natural soils. Sepsis caused by A. hydrophila infection is more common in immunocompromised hosts, but severe infection has been recorded in otherwise healthy people. Researchers discuss the case of a 40-year-old immunocompetent lady who developed pneumonia and septic shock as a result of A. hydrophila infection. Her clinical progress was exacerbated by acute respiratory distress syndrome, metabolic acidosis, and multiorgan failure, all of which resulted in death. Third- and fourth-generation cephalosporins, piperacillin-tazobactam, fluoroquinolones, and trimotheprim/sulfamethoxazole were all effective against the isolate. According to a review of the literature for prior instances of Aeromonas species infection in previously healthy patients, pneumonia and bacteremia caused by A. hydrophila can be fulminant and deadly. 

Early identification and treatment with suitable antibiotics are critical for minimising morbidity and death in A. hydrophila patients. Physicians should be aware of the problems that might arise from A. hydrophila infection.
