A surgery for American cuteneous and visceral leishmaniasis among 1,342 dogs from areas in Rio de Janeiro (Brazil) where the human diseases occur

Abstract

There are areas in the periphery of Rio de Janeiro city where human cases of Visceral and/or Cutaneous Leishmaniasis occur. The parasites have been identified as Leishmania donovani and Leishmania braziliensis braziliensis respectively. A survey for Leishmaniasis was done among 1,342 dogs from those areas using an indirect immunofluorescent test. From the dogs, 616 came from areas where only human cases of Visceral Leishmaniasis occurred, 373 from an area where all human cases were of Cutaneous Leishmaniasis and 353 from a third area (Campo Grande) where both visceral and cutaneous human cases were detected. The prevalence of parasite antibody titers among dogs from areas of Cutaneous Leishmaniasis was significantly higher than that of Visceral Leishmaniasis (8.6% vs. 4.3%, p less than 0.02). The highest prevalence was observed among dogs from the area where both diseases are present (12.7%).

Investigação sorológica em cães de área endêmica de leishmaniose tegumentar, no Estado do Paraná, Sul do Brasil

“…A presença de cães infectados em áreas endêmicas de leishmaniose tegumentar tem sido investigada, considerando seu papel como reservatório na cadeia de transmissão de Leishmania sp. nos ambientes domiciliar e peridomiciliar (Falqueto et al, 1986;Barreto et al, 1984;Coutinho et al, 1985;Sessa et al,1994). Na região Noroeste do Estado do Paraná, Lonardoni et al (1993) registraram a presença de cães infectados por Leishmania (Viannia) braziliensis.…”

“…(Coutinho et al, 1985;Falqueto et al, 1986) e os flebotomíneos são muito freqüentes no peridomicílio (Teodoro et al, 1993 …”

Space-time cluster analysis of American visceral leishmaniasis in Bauru, São Paulo State, Brazil

“…The study area comprises the city of Bauru which has a total area of 673.49km 2 Confirmed case counts were arranged in monthly distributions across the five year period. The method is described as:…”

Dogs are considered important reservoir hosts in urban areas as they carry the agent for long periods of time, favoring biologic vector-borne infections and, as a result, maintenance of protozoa 2,3 . In human begins, AVL is described as a serious disease and early diagnosis and treatment are vital to avoid fatalities 4,5 .…”

Tentativa de controle da leishmaniose tegumentar americana por meio do tratamento dos cães doentes

“…Nessas áreas, onde a doença acomete indistintamente adultos e crianças de ambos os sexos, também os cães estão freqüentemente parasitados (Falqueto, 1984;Coutinho et al, 1985;Aguilar et al, 1989). A população de flebotomíneos é sempre maior no ambiente peridomiciliar do que nas florestas remanescentes (Mattos, 1981;Gomes et al, 1982).…”
