RESUMO
Background : Leptospirosis, toxoplasmosis and brucellosis are diseases with worldwide distribution. Among stray dogs, these zoonoses are facilitated by direct contact with other animal species, by the habit of scavenging garbage and hunting in search of food, drinking standing water, smelling other animals' urine, licking female genitalia and the sexual act itself. The objective of this study was to detect antibodies anti-Toxoplasma gondii, anti-Leptospira spp., anti-Brucella canis and anti-Brucella abortus in stray dogs housed in shelters at Umuarama city, Paraná, Brazil. In order to detect toxoplasmosis, indirect immunofluorescence assay (IFA) was performed, agglutination microscopic (MAT) test for leptospirosis and agar gel immunodiffusion (AGID) and buffered acidified antigen (BAA) tests for brucellosis. Results : Of the 175 serum samples analyzed, 70.85% were considered positive for toxoplasmosis by IFA, 20% by MAT for leptospirosis and 2.85% by AGID for Brucella canis. Conclusions : The serological results of this study showed that stray dogs housed at the private shelter are potential carriers of these three different zoonoses and contribute to the spread and maintenance of these etiologic agents in the urban area of Umuarama (PR), Brazil.

A leptospirose é uma doença de caráter zoonótico, provocada pela Leptospira spp. Na área urbana, os cães errantes possuem 3,59 vezes mais risco de se infectar com esta enfermidade, pelo fato de formarem grupos quando fêmeas estão no cio, além da exposição com água empoçada e revirar lixos à procura de restos de alimentos que podem estar contaminados com urina de roedores ou animais infectados. O objetivo deste trabalho foi detectar anticorpos contra Leptospira spp. em um cão errante assintomático para avaliar seu potencial zoonótico. Foi coletado sangue de um cão errante assintomático de um canil privado da região Noroeste do estado do Paraná para a pesquisa de anticorpos contra Leptospira spp. pela SAM. A amostra foi considerada reagente, apresentando anticorpos contra o sorovar Canicola com título de 3.200. O resultado encontrado neste trabalho sugere a presença da Leptospira spp., entre os cães assintomáticos do referido abrigo, demonstrando a importância de se conhecer a ocorrência desta enfermidade que é uma zoonose de importância para saúde pública.
Leptospirosis is a zoonotic disease caused by Leptospira spp. In urban areas, stray dogs have 3.59 times higher risk of becoming infected with this disease because they form groups when females are in heat besides their exposure to still water and trash when looking for food scraps that may be contaminated by urine of infected rodents or animals. The objective of this study was to detect antibodies against assymptomatic Leptospira spp. in a stray dog ??to evaluate its zoonotic potential. Blood was collected from an asymptomatic stray dog of a private shelter in the northwest of Paraná state for antibodies against Leptospira spp. by SAM. The sample was considered reactive, with antibodies against serovar Canicola title with 3.200. The findings of this study show the presence of Leptospira spp. among asymptomatic dogs of that shelter, demonstrating that knowing the occurrence of this disease is a zoonosis of public health importance.
