LARA, Valéria Maria; TANIWAKI, Sueli Akemi and ARAUJO JUNIOR, João Pessoa. Occurrence of feline immunodeficiency virus infection in cats. Cienc. Rural [online]. 2008, vol.38, n.8, pp. 2245-2249. ISSN 0103-8478. http://dx.doi.org/10.1590/S0103-84782008000800024.
The occurrence of feline immunodeficiency virus (FIV) in Brazil has been previously described. This study aimed to investigate the frequency of FIV infection in 454 blood samples from healthy and sick domestic cats from 13 cities of São Paulo State, Brazil as well as to evaluate the risk factors associated with the infection. The results showed that 14.7% (67/454) of the cats were infected with FIV. The clinical evaluation showed that 29.2% of the FIV-positive animals were sick, while 7.3% did not show any type of clinical manifestation. In addition, the vast majority (23.1%) of positive cases corresponded to free-roaming owned cats. The incidence of FIV infection was higher in males (20.3%) than in females (9.7%). The results suggest that certain characteristics such as gender, health status and lifestyle may be associated with the risk of being infected with FIV in the population of cats studied.
