Resumo
Este estudo teve como objetivo determinar a soroprevalência e variáveis epidemiológicas associadas à LVC em área indene no interior do Estado de São Paulo - Brasil. Fizeram parte deste experimento 500 cães (n=500) provenientes da rotina de clínicas veterinárias de 11 municípios das microrregiões de Ourinhos e Avaré. Para isso, as análises sorológicas de ELISA e RIFI foram realizadas pelo laboratório TECSA®. Este estudo foi pioneiro em realizar este levantamento. Foi registrado soropositividade em cães onde o diagnóstico de LVC ainda não havia sido realizado. Dos 500 cães avaliados, 3,2% foram soropositivos para LVC no ensaio ELISA e 14,6% (12,2% reagentes 1:40 e 2,4% reagentes 1:80) na RIFI. Os resultados obtidos indicam que o município de origem dos cães, sexo, estado de saúde, vacinação e a presença de carrapatos são variáveis epidemiológicas inerentes aos cães capazes de influenciar na soroprevalência da LVC nas microrregiões estudadas, em contrapartida, a idade, o porte, a cor e o comprimento da pelagem, o ambiente e o método de prevenção contra ectoparasitos não se demonstraram como fatores de risco à LVC neste estudo.
This study aimed was to determine the seroprevalence and the epidemiological variables related to CVL in dogs of an undamaged area of São Paulo State countryside, Brazil. Were included 500 dogs (n=500) from the routine of veterinary clinics in 11 cities assigned to the microregions of Ourinhos and Avaré. The serologic analyzes of ELIZA and RIFI were performed by the laboratory TECSA®. This was a landmark study to assess this topic. Seropositivity was registered in dogs not previously diagnosed with CVL. From the totality of dogs, 3.2% were seropositive to CVL in ELISA and 14.6% (12.2% reagents 1:40 and 2.4% reagents 1:80) in IFI assay. The data suggest that the city of origin of the dogs, their gender, health status, immunization and the presence of ticks are capable to interfere in the seroprevalence of CVL at the surveyed microregions. On the other hand, age, size, color and length of the coat, environment and method for prevention of ectoparasites were not identified as risk factors for CVL. Keywords: leishmaniasis,
