Resumo
As leishmanioses são zoonoses que acometem o homem e outras espécies de mamíferos silvestres e domésticos. É uma doença causada por protozoários intracelulares do gênero Leishmania. O agente causador da leishmaniose visceral no Novo Mundo é Leishmania infantum (syn. L. chagasi), sendo Lutzomya longipalpis o principal vetor responsável pela sua transmissão. O gato doméstico também desenvolve a infecção, geralmente de forma assintomática, podendo atuar também como reservatório destes protozoários. Tendo em vista a inespecificidade dos achados clínicos da leishmaniose felina (LF), a ausência de sinais e a semelhança dos aspectos clínicos dessa enfermidade com outras enfermidades em gatos, como a micoplasmose, leucemia felina (FIV) e síndrome da imunodeficiência felina (FeLV), esta zoonose deve ser sistematicamente incluída nas suspeitas clínicas de gatos em áreas endêmicas para leishmanioses canina e humana. Foram utilizadas amostras de sangue de 55 gatos procedentes da Associação Protetora dos Animais (APAISA) de Ilha Solteira, co-habitantes com cães portadores de leishmaniose visceral. À técnica de hemocultura, 16,4% (9/55) dos gatos apresentaram protozoários flagelados. A Reação de Imunofluorescência Indireta (RIFI) para L. infantum (syn. L. chagasi) foi testada em 51 gatos, revelando 62,7% (32/51) de animais reagentes. Testando-se a técnica de RIFI para Trypanosoma cruzi, 54,9% (28/55) dos animais foram reagentes. Pela busca de anticorpos anti-Leishmania e anti-Trypanosoma, pela técnica de ELISA indireto com antígeno bruto, encontrou-se 72,5% (37/51) e 39,2% (20/55) de animais reagentes, respectivamente. Com o teste de ELISA indireto com rK39 para Leishmania infantum (syn. L.chagasi), obteve-se a positividade em 21,6% (11/51) dos felinos testados. Pela Reação em Cadeia pela Polimerase (PCR), das 55 amostras de sangue total testadas, cinco (9,1%) foram positivas...
The leishmaniasis are zoonoses that affect humans and other species of wild and domestic mammals. It is a disease caused by intracellular protozoa of the genus Leishmania. Leishmania infantum (syn. L. chagasi) is the causative agent of visceral leishmaniasis in the New World, Lutzomyia longipalpis is the main vector responsible for transmission. The cat, besides living closely with humans, also develops infection, usually asymptomatic and may also act as a reservoir of these protozoa. Given the specificity of clinical feline leishmaniasis (LF), the absence of pathognomonic signs and symptoms, and the similarity of the clinical aspects of this disease with other very common in cats, as mycoplasmosis, feline leukemia virus (FIV) and immunodeficiency syndrome FeLV (Feline), this zoonosis should be systematically considered in the clinical suspicions of cats in of the areas endemic for canine and human leishmaniasis. Samples of blood from 55 cats coming from the Association for the Protection of Animals (APAISA) of Ilha Solteira, co-inhabitants with dogs with visceral leishmaniasis, were collected. The blood culture technique showed 16,4% (9/55) flagellate protozoa. The technique of indirect fluorescent antibody (IFA) for L. infantum (syn. L. chagasi) was tested on 51 cats, showing 62,7% (32/51) of animals reagents. Testing the technique of IFA for Trypanosoma cruzi, 54,9% (28/55) of animals were reactive. The search for anti-Leishmania antibodies and anti-Trypanosoma, the technique of ELISA with crude antigen, we found 72,5% (37/51) and 39,2% (20/55) of animals reagents, respectively. By ELISA with indirect rK39 for Leishmania infantum (syn. L.chagasi) gave a positive result in 21,6% (11/51) of tested cats. For the PCR, the 55 whole blood samples tested, five (9.1%) were positive for Leishmania spp. Confronting all the results obtained with the diagnostic techniques , is possible to determine the ...
