Afegir etiqueta | Sumari: | Bovine tuberculosis (BTB) is a chronic granulomatous disease that affects a wide range of hosts including humans, and the causative agent is Mycobacterium bovis. BTB studies in our country are scarce, random and use different formats. It has therefore been proposed to generate information from southern Ecuador to alert people to the disease hence this research called "Prevalence of bovine tuberculosis (BTB), in the Canton of Loja, during post-mortem inspection in refrigerated slaughterhouses ". Analyses were performed at the Laboratory of Animal Microbiology, of the Biotechnological Center at the National University of Loja, from November 2014 to June 2015 . The variables under study were: Origin of bovine by parish; sex; race; and age of slaughtered cattle. Macro inspection of the ganglia of different sections of the carcass was carried out to establish pathological changes thereof and a smear test subjected to the Ziehl-Neelsen staining method was administered in the laboratory. The sample comprised 630 nodes (cervical, lung, retropharyngeal, bronchial and mediastinal) from 127 slaughtered cattle. The results showed the presence of the BTB disease in herds from the Canton of Loja, with 27.56% of positive cases from cattle emanating from different herds. Higher prevalence was detected in herds from the Sucre, El Valle, San Lucas and Jimbilla parishes. No significant differences in prevalence were perceived between sexes, likewise there was no evidence that race impacted on the prevalence. However, there was an increased susceptibility in animals over 3 years of age highlighting the presence of Mycobacterium in apparently normal glands (with 58.06%), without any significant clinical changes, a fact that becomes a highly dangerous factor in a disease which moreover is zoonotic.
