dc.descriptionApós o surgimento do foco de leishmaniose tegumentar em Solano, Estado de Cojedes, Venezuela, 5% da população possuíam úlceras parasitadas, enquanto que em Mesquita, Estado do Rio de Janeiro, Brasil, 9% apresentavam a doença. Nos dois focos, crianças com menos de seis anos eram acometidas. Não existe diferença significativa na ocorrência da doença entre sexos ou entre trbalhadores domésticso e agricultores. Em solano, 3% dos cães e 28% dos equinos apresentavam lesões paraditadas; em Mesquita estes índices eram de 19,8% e 30,8%, respectivamente. O parasito isolado de humanos, cães e equinos foi identificado como Leishmania (Viannia) braziliensis, através da análise de zimodema e serodema. Neste foco existe uma evidência sugerindo que a leishmaniose é uma zoonose, onde os equinos e os cães seriam os prováveis reservatórios. Entretanto, o ciclo enzoótico silvestre não foram devidamente avaliados. A transmissão nestes focos é provavelmente peridomiciliar, envolvendo vetores ecléticos como Lutzomyia panamensis, na Venezuela, e Lutzomya intermedia, no Brasil. Dados sobre a origem destes focos sugerem que equinos infectados são importantes na disseminação do parasita em área ecologicamente receptivas.
dc.descriptionAfter outbreaks of cutaneous leishmaniasis in Solano State, Venezuela, 5% of the population had parasitized ulcers while after similar outbreaks in Mesquita, Rio de Janeiro State, Brazil, 9% had the disease. In these foci children, including some under six years of age, wre affected. There was no significant difference in the occurence of the disease according to sex or type of employment. In Solano, 3% of dogs and 28% of donkeys had parasitized lesions, while in Mesquita these indices were 19.8% and 30.8% respectively. The parasite from man, dogs and equines was identified as Leishmania (Viannia) braziliensis, by zymodeme and serodeme characterization. In these foci there is evidence suggesting that leishmaniasis is a zoonosis, possibly with equine and dogs as reservoirs, although both a wild enzootic cycle and the role of man as a source of infection can not be ruled out. Transmission is assumed to occur peridomestically by sandfly vectors such as Lutzomyia panamensis in Venezuela and Lutzomyia intermedia in Brazil. Information about the origin of these foci suggests that infected equines may be an important factor in the dissemination of the parasite in a peridomestic situation where these sandflies are abundant.
