Year: 2025
Type: article
Abstract: Feline Viral Leukemia (FeLV) is a highly contagious infectious disease that affects domestic and wild felines worldwide and is not transmitted to humans.It is caused by the Gammaretrovirus, which is responsible for causing immunosuppression and oncogenicity, associated with concomitant infections that can lead to the death of the animal.The main source of infection is viremic cats, being transmitted through saliva, oronasal route and by indirect contact.The purpose of this study was to carry out a retrospective survey to analyze the risk factors that predispose to the incidence of FeLV in the region of Uberlândia-MG.A total of 162 medical records of domestic cats were examined between June 2023 and March 2024.Laboratory tests were analyzed by Chromatographic Immunoassay for qualitative detection of FeLV p27 antigens.The results indicated 26 reactive animals, obtaining a prevalence and morbidity percentage of 16.04%, 2 of these animals presented co-infection for (FIV+ and FELV+).The calculation of the average rate of accumulated prevalence, a variable of 12.85% was noted.Regarding the indicators regarding sex, 14.90% males were observed, against 9% reactive females, the proportion between male/female was 1.89:1, without a significant proportion in the data.Regarding prevalence, it was observed that for every 100 animals examined, 16 were reactive to the virus.It was noted that the lack of data collection and storage makes it difficult and impossible to perform a more assertive and expressive analysis of the true situation, justifying the high rate of variation in the prevalence of infection in the city.
