What is Aeromonas hydrophila in humans?
Aeromonas hydrophila is a water-dwelling, gram-negative rod-shaped bacterium, associated with diarrheal illness and, less commonly, necrotizing skin and soft tissue infections, especially among immunocompromised patients.
What does Aeromonas cause?
Aeromonas hydrophila is a motile, Gram-negative, rod-shaped bacterium in the family Vibrionaceae. It causes a broad spectrum of infections (septicaemia, meningitis, endocarditis) in humans, often in immunocompromised hosts, and Aeromonas spp. have been associated epidemiologically with travellers diarrhoea.
How do you identify Aeromonas hydrophila?
Approach to Identification: Aeromonas species are facultative anaerobes that are oxidase and catalase positive. This test must be performed on media without a fermentable sugar (ie MacConkey agar), because the fermentation process results in acidification of the medium and a false-negative result may result.
Is Aeromonas infection contagious?
Aeromonas-induced diarrhea is a contagious disease seen in both industrialized and developing countries in all age groups (3).
Is Aeromonas hydrophila a parasite?
Any bacterium that has a parasitic interaction with another organism is classified as a pathogen. Just like tetanus, C. difficile, and Leprosy, Aeromonas hydrophila is also classified as a pathogen to several organisms. In fact, it is the most common pathogen associated with fish illness.
Which Aeromonas species are associated with Wound infections?
A. hydrophila, Aeromonas veronii, and Aeromonas schubertii are the species most commonly isolated from wound infections [ 4,8,20,48 ].
What is Aeromonas hydrophila?
Aeromonas hydrophila: a type of bacteria commonly found in freshwater or brackish water and in some fish and shellfish. It may cause stomach upset, diarrhea, and vomiting in some individuals if swallowed.
What are the signs and symptoms of Aeromonas infections?
Diarrheal disease is the most common manifestation of Aeromonas infection. The organism has also been associated with a variety of extraintestinal presentations [ 4,8,12,36-38 ]. Diarrhea — Aeromonas spp are associated with a range of diarrheal presentations including:
How common is Aeromonas hydrophila infection in monkeys?
Cases were sporadic and occurred more frequently in New World monkeys than in Old World species. Aeromonas hydrophila infection was diagnosed in a cotton-top tamarin with peritonitis. The tamarin had a history of chronic weight loss and intermittent diarrhea; it presented with abdominal bloating and weakness.
