Previous issue date: 2007-10-16 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / The American Cutaneous Leishmaniasis (ACL) is a no contagious infectious illness caused by Leishmania protozoa genera affecting skin and mucous membranes basically being a zoonotic infection. The aim of this study was to cany out phlebotominic fauna survey in ACL human cases occurrence areas. For sandfly collection monthly systematic captures by Castro trap from 6 o clock p.m. to 10 o clock p.m. for 12 months were performed. The diptera were placed on 70% alcohol bottles and carried to Sergio Arouca Public Health National School Biological Sciences Department Vectors Laboratory, Oswaldo Cruz Foundation, Rio de Janeiro, where they have been clarified and identified, as well. For dogs serology, blood samples from invaded residences animals as well as from a neighbour one, by venous puncture were taken. After serum centrifugation and separation, samples were stored at 20?C till serological assays performance at FIOCRUZ Public Health Nation School Immunodiagnosis Laboratory. The following methods: Indirect Immunofluorescence Reaction (IFIR) and Enzyme-linked immunosorbent assay (ELISA) were used. From October, 2004 to September, 2005, 2390 units from four species were captured. The predominant species was the Lutzomyia intermedia with 97.1% from total collected, followed by L. whitmani 1.6%, L.migonei 1.21% and L.oswaldoi 0.09 %. From 35 dogs serology: 60% (21) no reagent animals were reported, 22.9% just for ELISA, 2.9% for IFIR, and 14.2% (5) reagent animals for both techniques, definitely positive. No correlated evidences between serologies (IFIR+/ELISA+ and other results) in regard to animals residence (ill or neighbour) by Fisher statistical test were reported. It might be suggested that ACL transmission in Serop?dica County has basically been spread by Lutzomyia intermedia specie. The presence of reagent dogs unless suggestive injury may contribute for new ACL reports. / A Leishmaniose Tegumentar Americana (LTA) ? uma doen?a infecciosa n?o contagiosa causada por protozo?rios do g?nero Leishmania que acomete a pele e mucosa, sendo primariamente uma infec??o zoon?tica. O objetivo desta pesquisa foi realizar o levantamento da fauna flebotom?nica em ?reas com ocorr?ncia de casos humanos de LTA. Para coleta dos fleb?tomos foram realizadas capturas mensais sistem?ticas utilizando o capturador de Castro, no hor?rio das 18 ?s 22h, durante 12 meses. Os d?pteros foram colocados em frascos contendo ?lcool 70% e transportados para o laborat?rio de Vetores do Departamento de Ci?ncias Biol?gicas da Escola Nacional de Sa?de P?blica S?rgio Arouca, Funda??o Oswaldo Cruz, RJ, onde foram clarificados e identificados. Para sorologia dos c?es, amostras de sangue foram coletadas por venopun??o em animais residentes nos domic?lios acometidos e de c?es vizinhos. Ap?s centrifuga??o e separa??o do soro, as amostras foram conservadas a -20?C, at? o momento da realiza??o dos ensaios sorol?gicos no laborat?rio de Imudiagn?stico da ENSP, da FIOCRUZ. Empregaram-se os seguintes m?todos: Rea??o de Imunofluoresc?ncia Indireta (RIFI) e o enzyme-linked immunosorbent assay (ELISA). Foram capturados 2390 exemplares de flebotom?neos entre os meses de outubro de 2004 a setembro de 2005, pertencentes a quatro esp?cies. A esp?cie predominante foi a Lutzomyia intermedia com 97,1% do total coletado, seguida pela L. whitmani 1,6% , L.migonei 1,21% e L.oswaldoi 0,09 %. Da sorologia de 35 c?es: 60% (21) animais foram considerados n?o reativos; 22,9% reativos somente para ELISA; 2,9% somente RIFI e 14,2% (5) dos c?es reativos para as duas t?cnicas, conclusivamente positivos. N?o houve evid?ncias de associa??o entre sorologia (RIFI+/ELISA+ e outros resultados) com a propriedade do animal (paciente ou vizinho), segundo o teste exato de Fisher. Aparentemente a transmiss?o da LTA no munic?pio de Serop?dica esteja sendo veiculada pela L. intermedia. A presen?a de c?es reativos sem a exist?ncia de les?o sugestiva pode contribir para novos focos da LTA, funcionando como um animal em potencial para manuten??o da protozoose.
