Alternative Title
Frequency of presentation of bacterial agents of shrimp (Litopenaeus vannamei) in farms during two seasons of the year in Cuba.
Abstract
En el presente trabajo se realizó una evaluación de la frecuencia de presentación de agentes bacterianos del camarón (Litopenaeus vannamei) en dos granjas de cultivo durante las estaciones de lluvia y seca en Cuba. Para el estudio se tuvieron en cuenta 14 muestreos realizados en el período comprendido entre los años 2007-2012.Para el cálculo de la frecuencia de presentación de los géneros de las bacterias identificadas se empleó el software Epidat 3.1 recomendado por OPS para análisis epidemiológicos y el test de Duncan con el programa Compapro. Además, se realizó una estadística descriptiva con el paquete estadístico STATGRAPHICS Centurión XV Versión 15.2.05. Los resultados indican que hubo un predominio de crecimiento de Aeromonas spp. y Vibrio spp. en período lluvioso, excepto Pseudomonas spp. que significó el 26,4 % de aislamientos en el período seco. Estos resultados demuestran que la época del año presenta una influencia altamente significativa para p ≤ 0,001 en los aislamientos de especies de microorganismos, lo cual confirma que la época del año hace del ambiente un factor variable de comportamiento cíclico, provocando variabilidad en la presencia y patogenicidad de las bacterias del medio y de los organismos acuáticos.
This paper was carried out an evaluation of the frequency of presentation of bacterial agents of shrimp (Litopenaeus vannamei) in two farms during rainy and dry seasons in Cuba. For the study, there were analyzed a total of 14 shrimp samples during the period 2007-2012. For the calculation of the frequency of presentation of the genera of the bacteria identified, we used Epidat software 3.1 recommended by OPS for epidemiological analysis and the Duncan test with the program Compapro. Besides, it was used a statistical package STATGRAPHICS Centurión XV Version 15.2.05 for a descriptive statistic. As result, there was a predominance of growth of Aeromonas spp and Vibrios spp. in the raining season, except Pseudomonas spp. which represented 26,4 % isolation in dry season. This result demonstrate that in both seasons, a significant influence for p ≤ 0,001 in isolation of microorganism species. And this confirm, that this epoch, makes of the enviroment a variable factor of cyclic behavior, provoking variability in the presence and pathogenicity of the bacteria in the medium and acuatic organisms.
