Resumo: In order to evaluate the occurrence of Toxoplasma gondii infection in cats infected with feline immunodeficiency virus (FIV), 22 serum samples obtained from diseased cats harbouring FIV were submitted to an indirect immunofluorescence antibody test to Toxoplasma. Another 58 ill cats, but that were negative for FIV antibody test and 35 healthy animals, also FIV negative, comprised the second and the third group, respectively. All cats were negative for feline leukemia virus test. The results showed that cats infected with FIV (Grupo I) presented a higher frequency of Toxoplasma antibody titer when compared to groups II and III. Also, a strong correlation was detected between FIV infection and positive serum reaction for Toxoplasma gondii. On the other hand, there was no difference in the magnitude of Toxoplasma antibody titer between positive and negative cats. Although cats that are seropositive to Toxoplasma rarely excrete oocysts in their feces, it is not well known how this immunity can influence oocysts shedding in cats infected with FIV. In consequence of the high frequency of antibody titer to Toxoplasma in FIV positive cats, these animals should always be submitted to antibody test to Toxoplasma.

Utilizaram-se 115 amostras de soro sangüíneo de gatos negativos ao vírus da leucemia felina que foram divididas em 3 grupos. Os 22 animais do grupo I eram positivos ao VIF. Os 58 animais que compuseram o grupo II eram doentes porém negativos na pesquisa de anticorpos anti-VIF e os 35 felinos do grupo III eram hígidos e negativos ao VIF. Os resultados obtidos permitiram concluir que a freqüência de anticorpos antitoxoplasma foi maior no grupo I do que nos grupos II e III. A análise estatística mostrou forte associação entre a infecção pelo VIF e a presença de anticorpos antitoxoplasma. Não se observou diferença entre a magnitude dos títulos de anticorpos antitoxoplasma nos animais positivos e negativos ao VIF. Embora gatos que desenvolvam imunidade raramente eliminem oocistos, não se sabe exatamente como esta imunidade pode influenciar a eliminação de oocistos naqueles gatos infectados pelo VIF. Em face da alta freqüência de anticorpos antitoxoplasma observada nos animais positivos ao VIF, acredita-se que todos os gatos positivos a esse vírus devam ser avaliados quanto à presença de anticorpos antitoxoplasma.Universidade de São Paulo.
