Toxoplasmosis, leptospirosis and brucellosis in stray dogs housed at the shelter in Umuarama municipality, Paraná, Brazil

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.(AU)

Leishmaniose tegumentar americana em cão errante da região noroeste do estado do Paraná - relato de caso / Cutaneous leishmaniasis in a stray dog in the northwestern region of the state of Paraná - a case report / Leishmaniose tegumentaria americana en perros callejeros de la región noroeste del estado de Paraná - relato de caso

A Leishmaniose Tegumentar (LT) é uma doença parasitária cosmopolita provocada por um protozoário pertencente à Ordem Kinetoplastida, família Trypanossomatidea e Gênero Leishmania e é transmitida por insetos dípteros hematófagos pertencentes à subfamília Phlebotominae. Nos cães a forma tegumentar se manifesta com lesões mucocutâneas, formação de úlceras de fundo granulomatoso e bordas salientes de difícil cicatrização. O objetivo deste trabalho foi relatar a presença de anticorpos anti-Leishmania spp. em um cão errante com sintomatologia clínica sugestiva para LTA na região noroeste do estado do Paraná. O resultado positivo no exame sorológico encontrado no presente trabalho sugere que houve a circulação do agente etiológico e, consequentemente, a exposição deste animal ao parasito, porém novos estudos com cães errantes e domiciliados com ou sem sintomatologia característica para LTA devem ser realizados para esclarecer melhor a participação do cão na epidemiologia da LTA no município local.(AU)

Cutaneous Leishmaniasis (CL) is a cosmopolitan parasitic disease caused by a protozoan belonging to the Kinetoplastida order, Trypanossomatidea family and Leishmania genus, and is transmitted by blood-sucking flies belonging to the Phlebotominae subfamily. In dogs, the cutaneous form manifests with mucocutaneous lesions, granulomatous bottom ulcers and difficult to heal flanges. This study aimed to report the presence of anti-Leishmania spp. in a stray dog with clinical symptoms suggesting LTA in the northwestern region of the state of Paraná. The positive serology found in the present study suggests that there was a movement of the etiological agent and, therefore, this animals exposure to the parasite, but further studies with stray and and domestic dogs with or without characteristic symptoms of LTA should be done to understand the role of a dog in the leishmaniasis epidemiology in the local municipality.(AU)
