Frecuencia de tuberculosis mediante la técnica de interferón gamma (IFN- γ) en bovinos del cantón Sevilla de Oro, Azuay

Abstract

Bovine tuberculosis (BBT) is a chronic, zoonotic disease that affects farm animals as well as wildlife. Their frequency is relatively high in developing countries, with a significant economic cost. The present research aimed to characterize the frequency of tuberculosis using the gamma interferon (ifng) technique in cattle. The research was descriptive, with a final sample of 150 cows in milk production from the parishes of Palmas, Sevilla de Oro and Amaluza, in the province of Azuay. Diagnostic analysis was performed using the gamma interferon (IFN-γ) technique to detect Mycobacterium bovis. The ID Screen® Ruminant IFNg ELISA kit was used. For data processing, the statistical program SPSS version 27 was used. Descriptive statistics of central tendency as mean and median were calculated, in addition to OR and the exact Fisher test, to evaluate the association between the frequency of tuberculosis and the variables studied. In terms of results, the median age was 55.5 months. Most of the cows were Holstein (74.7 %) and had between one and three litters (74%). The incidence of bovine tuberculosis was 5.33%. The only affected breeds are Holstein and Norman. Primiparous cows and those that had more than 4 litters were the ones with tuberculosis infection. In conclusion, the incidence of bovine tuberculosis was relatively low and there was no significant relationship to any of the risk factors.
