ABSTRACT
The National Laboratory of Reference of Pathogenic Neisserias of "Pedro Kourí" Tropical Medicine Institute studied 58 strains which had been previously identified as Neisseria meningiditis and isolated from nasopharyngeal carriers from 1985-1998. They were applied the knapp detection scheme plus the glutamiltransferase production test. The latter and the polyscharide production based on 5% sacarose allowed to make a differential diagnosis between N. meningitidis and Neisseria polyccharea. It was possible to identify a N. polysaccharia strain, a species that is reported for the first time in Cuba.

70 Aeromonas strains isolated from patients with acute diarrheal disease were classified into species by using the CAMP factor test and the Pyrazinamidase activity. It is stressed the high percent of coincidence between both tests, which are easy to make at the clinical microbiology laboratories.

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.
