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.

During 1988, a study was made on 61 microorganisms, genus Vibrio, which were received at the National Reference Laboratory for Acute Diarrheic Diseases. Pedro Kouri Institute of Tropical Medicine. Of them, 46 were from children with acute diarrheic disease and 15 were isolated from the environment. By means of biochemical tests. 61 Vibrio cholerae No. 01. 9 Vibrio parahaemolyticus and 1 Vibrio alginolyticus were identified. Emphasis is placed upon the importance of keeping a systematic surveillance upon these microorganisms in Cuba.

The Quibú River sewages were studied during 9 weeks, in order to isolate and characterize Vibrio genus microorganisms. Twenty Moore's hyssops were placed 2 or 3 times a week on the banks of the river, where each of them was kept in a passive capture stay for 24 hours. In all the hyssops placed, Vibrio cholerae non-01 were isolated.

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.
