Case Reports: Aeromonas Hydrophila Severe Gastroenteritis in Diabetic, Elderly Patients

, , ,


Introduction: Aeromonas hydrophila gastroenteritis is rare in humans and common amongst fish, reptiles and amphibians. In humans, infections caused by Aeromonas species usually occur with increased frequency during warmer months. The organism is frequently isolated from meat products and its transmission is by feco-oral route.

Clinical picture: We report 2 cases of Aeromonas hydrophila gastroenteritis in elderly, diabetic patients. Both patients had severe diarrhea and stool cultures grew Aeromonas hydrophila.

Treatment and outcome: Both responded to intravenous ceftriaxone and were discharged well.

Clinical implication: It is self limiting in immunocompetent hosts. In elderly, immunocompromised or pediatric patients, it can cause bacteremia and high mortality if not treated early.
