Cutaneous Leishmaniasis in a horse (Equus caballus) from endemic area in the state of Espirito Santo, Brazil
Leishmaniasis due to Leishmania braziliensis in Espírito Santo state, Brazil: further evidence on the role of dogs as a reservoir of infection for humans
Distribution of sand flies (Diptera: Psychodidae) at different altitudes in an endemic region of American cutaneous leishmaniasis in the State of Espírito Santo, Brazil

Distribution of Sand Flies (Diptera: Psychodidae) at Different Altitudes in an Endemic Region of American Cutaneous Leishmaniasis in the State of Espírito Santo, Brazil
The involvement of different sand fly species in the transmission of
American cutaneous leishmaniasis (ACL) at different altitudes was
evaluated in the municipality of Afonso Cláudio in the State of
Espírito Santo, Brazil, from November 1995 to February 1997. CDC
light traps and Shannon traps baited with human volunteers were hung
simultaneously at three altitudes of a river valley: (a) 650-750 m in
an area of active ACL transmission; (b) 750-850 m in a transitional
area; and (c) 850-950 m in an area where no ACL transmission occurred.
A total of 13,363 specimens belonging to 28 species was collected. The
five most abundant man-biting species were Lutzomyia intermedia, which
constituted 24.3% of the total, Lu. migonei (22.3%), Lu. whitmani
(15.4%), Lu. fischeri (14.9%) and Lu. monticola (5.8%). Analysis of the
distribution of these species at the three altitudes provided evidence
that Lu. fischeri and Lu. monticola were not involved in ACL
transmission, whereas Lu. migonei and Lu. whitmani might act as
secondary vectors of Leishmania (Viannia) braziliensis and Lu.
intermedia was probably the principal vector of the parasite. These
results reinforce those published in the existing literature, which
indicate that Lu. intermedia is the main vector of Le. (V.)
braziliensis in Southeast Brazil, while Lu. migonei and Lu. whitmani
are of secondary importance
Lutzomyia gasparviannai Martins, Godoy & Silva, 1962, probable vector of Leishmania mexicana ssp. in Viana municipality, Espírito Santo State, Brazil
<abstract language="por">Dos flebótomos atraídos pelo Proechimys iheringi numa área onde esse roedor foi achado naturalmente infectado por Leishmania mexicana ssp., 98,1% foram Lutzomyia gasparviannai, o que sugere que essa espécie não antropofílica seja o transmissor entre os roedores mas não habitualmente ao homem
Criadouros de Aedes (Stegomyia) aegypti (Linnaeus, 1762) em bromélias nativas na Cidade de Vitória, ES Aedes (Stegomyia) aegypti (Linnaeus, 1762) breeding sites in native bromeliads in Vitória City, ES
Alguns insetos transmissores de doenças procriam exclusivamente nas proximidades das residências. O Aedes aegypti, responsável por epidemias de dengue em cidades brasileiras, representa sério risco também para a febre amarela. Com o insucesso da campanha de erradicação do inseto, justifica-se a busca de criadouros fora do alcance das medidas de controle atualmente adotadas. Na Cidade de Vitória, ES, investigou-se a ocorrência de criadouros de Aedes aegypti na água coletada em bromélias nativas, sobre as rochas. Paralelamente, avaliou-se a infestação predial nas áreas urbanas contíguas. Em quatro das cinco áreas investigadas foram encontradas larvas de culicídeos nas bromélias, sendo que em duas foi identificado Aedes aegypti. A presença dos criadouros em bromélias não guardou relação com a infestação predial nas áreas próximas. Torna-se necessário definir se os criadouros em bromélias constituem focos primários do Aedes aegypti, ou se representam uma conseqüência da elevada infestação urbana.<br>Some insects that are vectors of human diseases have accompanied man in his migrations throughout the world and breed exclusively in the proximity of human dwellings. The mosquito Aedes aegypti has been responsible for epidemics of dengue in Brazil and its presence also constitutes a serious risk for future outbreaks of urban yellow fever. The failure of campaigns to eradicate this species justifies the search for alternative breeding sites, which may be beyond the reach of present control measures. In this study the occurrence of Aedes aegypti breeding sites in native bromeliads on rocky slopes was investigated in five areas of Vitória, capital of the Brazilian State of Espírito Santo, ES. Water contained in the bromeliads was collected with the aid of a suction apparatus to search for culicid larvae. The degree of infestation of buildings in adjacent urban areas was evaluated simultaneously. Culicid larvae were found in bromeliads in four of the five areas investigated, Aedes aegypti being present in two areas. The presence of breeding sites in bromeliads was not related to indices of infestation of buildings in adjacent areas. Further studies are necessary to define whether breeding sites in bromeliads constitute primary foci of Aedes aegypti, or are a consequence of high infestation levels in urban areas
