| Resumo: |
Las especies Yersinia ruckeri y Edwardsiella sp. son patógenos de importancia económica por la alta morbiletalidad que provocan en la acuicultura. En este trabajo se analiza la frecuencia de aparición y el comportamiento epizootiológico de ambos patógenos en los peces de cultivo en Cuba, en diferentes regiones del país y en sistemas de cultivo extensivo en embalses e intensivo en estanques y jaulas flotantes, del 2006 al 2008. Del total de brotes analizados, estas especies se encontraron en 18 eventos epizoóticos, cuatro en el 2006, 12 en el 2007 y dos en el 2008. Edwardsiella sp. se aisló en 16 de ellos, mientras que Yersinia ruckeri se encontró en nueve. Las especies afectadas fueron Oreochromis sp., Clarias sp. y Micropterus salmoides floridanus. Estos resultados indican que ambos patógenos provocan enfermedadades con importantes pérdidas económicas en Cuba y afectan con más frecuencia a las especies en cultivo intensivo.
Within Enterobactereaceae family only Yersinia and Edwardsiella genus are considered as fishes pathogens. Yersinia ruckeri and Edwardsiella sp. are the most important pathogens for aquaculture because their high morbility. In this study the frequency of apparition and the epizotiologic behavior of these bacterias in different regions of Cuba and in extensive and intensive culture system during the years 2006-2008 were analized. From the total of the epizootiologic events, these pathogens were found in 18: four in 2006, 12 in 2007 and two in 2008. Edwardsiella species were isolated in 16 and Yersinia ruckeri in nine. The affected species were Oreochromis sp., Clarias sp. and Micropterus salmoides floridanus. These results indicate that both pathogens cause illness with important economic looses in Cuba and that they affect species in intensive culture more frequently.
