RESUMO
We identified 100 strains of Gram-negative, oxidase-positive bacilli, facultative anaerobes, isolated from different human pathological products by conventional biochemical methods. From the total number of strains studied, 1 corresponded to genus Vibrio, 66 to genus Aeromonas, and 33 to genus Plesiomonas. It is of the utmost importance to conduct surveillance studies of these microorganisms in order to investigate their circulation in Cuba.

Aeromonas hydrophila caused severe disease in a group of 50 Xenopus leavis three weeks after being transferred from their laboratory conditions. The first clinical signs observed were marked pallor, petechiae, lethargy, anorexia, and edema. The duration of the disease was about 48 days, during which 4 animals acquired the disease and 10 died. The study of the bacteriology of the skin and skeletal muscles showed at necropsy subcutaneous edema, hemorrhage, and ascitis. Aeromonas hydrophila was isolated in 14 of the 50 animals studied.
