Isolation of Aeromonas species from clinical sources

Abstract

In a period of one year, in a general hospital, Aeromonas hydrophila was isolated from 13 patients and Aeromonas shigelloides from one patient. Eight of the patients had superficial infections, two had urinary tract infections, and four had bacteriaemia. The association of Aeromonas bacteriaemia with cirrhosis of the liver and malignant disease, which has been previously reported, was observed in three of the four bacteriaemic patients. The key to laboratory diagnosis of this genus is the routine performance of the oxidase test in bacteriological procedures for the identification of Gram-negative bacilli.
