Resistencia natural, in vitro, a los virus de estomatitis vesicular y de rinotraqueitis infecciosa en ganado Blanco Orejinegro

ABSTRACT: This report presents the results of a project whose goal was to determine the possible phenotypic diversity in, in vitro, resistance/susceptibility of the Colombian Criollo cattle, Blanco Orejinegro (BON), to the infection with Vesicular Stomatitis Virus (VSV) and Infectious Bovine Rinotracheitis Virus (IBRV). 47 primary fibroblasts cultures belonging to same number of animals were tested by means of viral titration, and the Minimum Infectious Dose 50% by ml (MID50%/ml) was determined by the Spearman karber method. Then the Resistance/Susceptibility Index (RSI) was obtained and the primary fibroblasts cultures were categorized as resistant or susceptible with reference to MDBK cells as susceptible control. For IBRV all primary fibroblasts cultures were susceptible; for VSV serotype Indiana, 37 were susceptible and 10 resistant, and for VSE serotype New Jersey, 41 were susceptible and 5 resistant. Our research group had previously demonstrated phenotypic polimorphism in, in vitro, resistance/susceptibility to foot and mouth disease virus in this cattle breed.
