[Clinical and diagnostic characteristics of Aeromonas strains].

We studied the taxonomic, clinic, microbiological diagnostic and therapeutic characteristics of Aeromonas strains. Eleven geno-species have been isolated in human. They can be enterotoxigenic or enteroinvasive. These bacteria can be easily confused with other Gram negative bacilli (the Aeromonas are oxidase positive). They produce diarrhea but can only colonizer. In others localizations they are always diagnostic. Their detection in stools can be realized with the blood agar plus ampicillin or cefsulodin-novobiocin-irgasan agar. The treatment of extraintestinal infection is similar to the Gram negative infections. The Aeromonas are resistant to erythromycin, streptomycin and first generation cephalosporin. The beta-lactamic antimicrobials aren't the election treatment because the are positive beta lactamase. The diarrhea in children and immunocompromised or chronic patients will be treated with cotrimoxazole or fluorquinole.
