Epidemiology of canine transmissible venereal tumor in Reynosa Tamaulipas Mexico

Abstract

The CTVT is transmitted mainly through sexual contact, with females being the most exposed to the pathology; vincristine sulfate is currently the most effective therapy. In the present work, 28 canines were analyzed, mostly of indefinite breed. A diagnosis was made by complete physical examination and sur­veys were carried out on their owners to determine risk factors. The proportion of the disease was similar in females and males under 5 years of age, but considerably higher in adult males than in females; only 25% of those older than 5 years were female. The incidence of this tumor in non-sterilized animals was 28% higher than in sterilized ones. The presence of the tumor was considerably higher in non-rescued males compared to females in the same condition (73 and 27%). Finally, 89% of the reported cases presented lesions in the genital region. The objective of this work was to identify factors associated with the persistence of CTVT in the city of Reynosa Tamaulipas.
