Abstract

Abstract Dioctophyme renale is a zoonotic parasite with worldwide distribution, although its occurrence is little known. The objective here was to evaluate the presence of parasite eggs in the environment and in the urine of dogs and cats in an urban area. Soil samples and urine were evaluated respectively by means of the Caldwell-Caldwell technique and urinalysis. Out of the 100 soil samples, 3% presented D. renale eggs, and out of the 43 urine samples, 18.6% were positive, including the feline samples. Thus, D. renale eggs are present in the urban environment, and dogs and cats are parasitized by this nematode, which therefore represents a risk to public health.Resumo Dioctophyme renale é um parasito zoonótico com distribuição cosmopolita, entretanto sua ocorrência é pouco conhecida. Assim, o objetivo foi avaliar a presença de ovos do parasito no ambiente e na urina de cães e gatos de zona urbana. As amostras de solo e urina foram avaliadas, respectivamente, pela técnica de Caldwell e Caldwell e por urinálise. Das 100 amostras de solo, 3% apresentaram ovos de D. renale, e das 43 amostras de urina, 18,6% foram positivas, incluindo a de felino. Conclui-se que ovos de D. renale estão presentes no ambiente urbano, assim como os caninos e felinos apresentam-se parasitados, representando um risco para a saúde pública.
