“…After significant changes in the surrounding environment or insecticide spraying, large numbers of anthropophilic phlebotomine species (such as Lutzomyia intermedia and L. migonei) are frequently observed inside and around dwellings at higher percentages than observed among the previously predominant wild species (DOMINGOS et al, 1998). This demonstrates that these factors exert a large influence on the dominance relationship, population size and biodiversity of the phlebotomine sandfly fauna (TEODORO et al, 1999). Areas that have undergone intense changes as a result of human action and that are densely populated become endemic at different times, and this cannot always be attributed to the occurrence of deforestation prior to the introduction of the disease into the community (MAYRINK et al, 1979).…”

“…The surrounding environment also seems to strongly influence occurrences of leishmaniasis as a result of the interaction of the community with the forest (NERY-GUIMARÃES, 1955;FOLLADOR et al, 1999;UCHÔA et al, 2001) and as a result of human changes that favor the establishment and growth of anthropophilic vectors (TEODORO et al, 1999). After significant changes in the surrounding environment or insecticide spraying, large numbers of anthropophilic phlebotomine species (such as Lutzomyia intermedia and L. migonei) are frequently observed inside and around dwellings at higher percentages than observed among the previously predominant wild species (DOMINGOS et al, 1998).…”

The objective of the present study was to investigate the dynamics and profile of American Cutaneous Leishmaniasis (ACL) in an old colonization area in the State of Rio de Janeiro. Health departments of municipalities in the Central-Southern region that had notified cases to the Ministry of Health's Notifiable Diseases Information System between 1997 and 2002 were contacted to obtain data. Out of the 119 cases recorded, 51 patients were visited for an interview and inspection of the environment. The cases of ACL exhibited a profile similar to that observed in other Brazilian cities, affecting individuals of both genders, all age groups and different occupational categories, especially students. Risk activities were reported by 56.9% of the interviewees and 84.3% had never left their homeland. Water courses, chicken coops, bamboo plantations and different fruit trees including banana plants and mango trees were frequently observed in the surrounding environment. Most of the interviewees had not noted any environmental changes prior to becoming sick. Domestic animals were present in all homes, but only dogs presented lesions suggestive of the disease. These were on different occasions that rarely preceded or coincided with the human cases. The possible existence of distinct transmission cycles, i.e. one for canines and another for humans, was discussed.Keywords: American Cutaneous Leishmaniasis, Leishmania (Viannia) braziliensis, zoonotic diseases, epidemiology. ResumoEste estudo teve como objetivo conhecer a dinâmica e o perfil da Leishmaniose Tegumentar Americana (LTA) em uma área de colonização antiga do Estado do Rio de Janeiro. As secretarias de saúde dos municípios da Região Centro-Sul que notificaram casos ao Sistema de Informação de Agravos de Notificação do Ministério da Saúde entre os anos de 1997 e 2002 foram contactadas para obtenção dos dados. Do total de 119 casos registrados, 51 pacientes foram visitados para realização de entrevista e observação do ambiente. A LTA exibiu perfil semelhante ao de outras cidades brasileiras, acometendo indivíduos de ambos os sexos, de todas as faixas etárias e diversas categorias ocupacionais, principalmente estudantes. A realização de atividades de risco foi relatada por 56,9% dos entrevistados e 84,3% não se deslocaram do município de residência. No ambiente circundante havia, frequentemente, cursos d'água, galinheiros, bambuzais e diversas frutíferas, entre elas: bananeiras e mangueiras. A maioria dos entrevistados não observou mudanças ambientais anteriormente ao adoecimento. Animais domésticos estiveram presentes em todos os domicílios, mas apenas cães evidenciaram lesões sugestivas da doença em ocasiões diversas, raramente antecedendo ou coincidindo com casos humanos. A possibilidade de existirem ciclos de transmissão distintos, um canino e outro, humano, foi discutida.

“…There are indications of higher transmission rates in Pernambuco State, Brazil, where forests are being degraded extensively, and in peridomestic habitats in deforested regions of Brazil. Surprisingly, Teodoro et al (1999) found that despite tree removals and applications of low-volume insecticide along the forest edge, L. whitmani populations continued to increase (originally reported in Brandão-Filho et al 1999).…”

-There are nearly 500 species of sandfl ies in Americas, 30 of which are vectors of leishmaniasis. Evandromyia cortelezzii (Brèthes), E. sallesi (Galvão & Coutinho) and E. corumbaensis (Galati et al) comprise the cortelezzii complex. These species are morphologically similar and many times misidentifi ed. Due to the epidemiological importance recently attributed to this complex, a detailed study was carried out in order to correct wrongful information due to their misidentifi cation, and update their geographical distribution. Evandromyia corumbaensis was found to have a regional distribution, while the other two species are widely distributed in the Brazilian territory. (Galati et al 1989), espécies muitas vezes confundidas, gerando erros em suas identifi cações.Os machos de E. corumbaensis diferenciam-se por apresentarem maior número de cerdas no tufo do basistilo e os dutos ejaculadores mais longos. E. sallesi apresenta a região dorsal do parâmero linear, sem concavidades, dando ao mesmo aspecto mais largo e robusto do que aquele de E. cortelezzii, o qual apresenta região dorsal mais côncava, resultando em parâmero mais estreito. Apenas a fêmea de E. corumbaensis pode ser separada das demais, devido aos dutos individuais mais longos e mais fi nos que nas outras espécies.Segundo Young & Duncan (1994), E. corumbaensis teria distribuição geográfi ca restrita, ocorrendo apenas no Mato Grosso do Sul. E. cortelezzii seria restrita a Argentina e Uruguai, enquanto E. sallesi seria largamente distribuída pelo território nacional e por alguns países sul americanos. Essa distribuição geográfi ca é basicamente a mesma dada por Martins et al (1978), apresentada antes da descrição de E. corumbaensis.Devido à difi culdade de identifi cação das espécies desse complexo, tornou-se rotineiro, com raras exceções (Rangel et al 1990), utilizar a distribuição geográfi ca para a identifi cação das mesmas. Dessa forma, os exemplares provenientes
