FERNANDEZ ABREU, Anabel et al. Isolation and identification of Aeromonas and Plesiomonas in "Niña Bonita" dam in City of Havana province, Cuba. Rev Cubana Med Trop [online]. 2008, vol.60, n.2, pp. 0-0. ISSN 1561-3054.

Objective: A study on "Niña Bonita" reservoir waters located in City of Havana province was conducted to find out the circulation of Aeromonas and Plesiomonas genus microorganisms. Methods: Ten Moore swabs were placed at different points of this reservoir in 2002, which were examined in the National Reference Laboratory of Diarrheal Diseases of "Pedro Kourí" Institute. Aeromonas species were determined through Aerokey II and Aeroesquema schemes, being the latter also used for Plesiomonas detection. Serotyping was performed according to the International Serotyping Scheme. Results: twenty three strains were isolated from the swabs of which 18 (78 %) belonged to the Aeromonas genus and 5 (22 %) to Plesiomonas genus. In order of frequency, the identified Aeromonas species were A. veroniir bv sobria (33 %), A. trota (28 %), A. jandaei (22.5 %), A. hydrophila (11 %) and A. caviae (5.5 %). Out of the 5 Plesiomonas shigelloides strains, 3 were non-typable and 2 corresponded to serotypes O9:H2 and O76:H39, being the latter detected for the first time in our country. Conclusions: The circulation of Aeromonas and Plesiomonas strains in "Niña Bonita" reservoir was confirmed, which could pose a risk for human health.
