Abstract

The transmissible venereal tumor (TVT) is a neoplasm of round cells, infectious character that affects mainly dogs of reproductive age living in areas of humid temperate climate, and coitus their main form of transmission. This study aimed to carry out an epidemiological survey of transmissible venereal tumor INOCOOP neighborhood, Cruz das Almas - BA. And the following objectives estimate the number of neighborhood dogs, quantify the affected animals by the TVT, identify the owners' knowledge about the subject, to correlate the incidence of TVT with animal breeding system and identify what stage of the estrous cycle the females were by cytology. To this end, we obtained the signature of informed consent form and then applied two questionnaires to obtain information such as sex, breeding system, sexual contact, the owner's knowledge about the subject, among others, in 286 (50%) homes in the neighborhood. Among these, 83 (29%) there was no one, 90 (31.5%) did not have dogs, 113 (39.5) had, for a total of 170 dogs, but only 69 (61%) owners agreed to participate research, and were home at the time of the second questionnaire and harvested material, and 34 (30.1%) were not in the property at the time of application of the second questionnaire and harvested material and 10 (8.9%) possessed dogs, but not agreed to participate. Animals were analyzed by cytology genital using the swab technique and females, it was possible to identify the estrous cycle. 81 samples were collected, of which only one (1.2%) positive animals introduced himself to TVT, but this was already in treatment, which hampered viewing round cell. He was not neutered, had a history of sexual activity and was created like dog set free system. Of the 49 females analyzed 22 (44.9%) were in the pro-estrus; 10 (20.4%) in the estrus phase; 9 (18.4%) in diestrus and 5 (10.2%) were in anestrus, and 3 (6.1%) samples were discarded for not having minimum for counting and differentiation of cells. In this study it was concluded that the incidence of transmissible venereal tumor in the neighborhood was low, and most owners reported no knowledge of the disease, the number of neighborhood dogs was estimated based on half of the residences of the district, Cytological analysis of females demonstrated that most was in the proestrus stage.
