Factores de Virulencia en Cepas de Aeromonas spp
Abstract: Some species of Aeromonas have emerged as important pathogens associated with the development of gastrointestinal and extra-intestinal infections. The objective of this study was to evaluate the potential virulence of Aeromonas strains from vegetables. Virulence factors were analyzed: DNas...

The objective of this study was to evaluate the potential virulence of Aeromonas strains from vegetables. Virulence factors were analyzed: DNase, lecitinasa, caseinase, gelatinase, hemolysines and hemaglutinies, in 59 strains of A. hydrophila and 61 of A. caviae, isolated from coriander, parsley and lettuce obtained in establishments in Maracaibo city. The results were analyzed through statistics c2. The virulence factors studied were expressed for more of the 80% of the strains. Four of the 6 factors were expressed in greater proportion in Aeromonas hydrophila strains, although the difference between the species only significant in for caseinase expression (94.9% vs 72.1%, p <0.05). All strains exhibited DNase activity. The lecitinasa expression result slightly higher in A. caviae strains (p> 0.05). A significant difference was evident in the number of virulence factors expressed by the two species, being higher for A. hydrophila (p <0.05). The expression of a large number of virulence factors the analyzed Aeromonas strains, allow to attribute a potential of pathogenicity to the strain of human infections. Resumen: Algunas especies de Aeromonas han emergido como patógenos importantes, asociadas al desarrollo de infecciones gastrointestinales y extraintestinales. El objetivo de este estudio fue evaluar el potencial de virulencia de cepas de Aeromonas procedentes de vegetales. Se analizó los factores de virulencia: DNAsa, lecitinasa, caseinasa, gelatinasa, b-hemolisinas y hemaglutininas, en 59 cepas de A. hydrophila y 61de A. caviae, aisladas de cilantro, perejil y lechuga, comercializados en Maracaibo. Los resultados fueron analizados mediante el estadístico c2. Los factores de virulencia estudiados fueron expresados por más del 80% de las cepas.
