“…In 2005, the first and only VL human case of Ilha Grande was recorded in a fisherman’s village at Enseada das Estrelas, approximately 20 km away of Praia Vermelha, where L. (L.) longipalpis had been detected in the late 1970s by Araújo Filho & Sherlock [ 13 ]. Following the notification of this VL case, the Health Department of Angra dos Reis Municipality (FuSAR) performed sand fly surveys on the area, as part of the entomologic surveillance activities.…”

BackgroundThe south coast of Rio de Janeiro State, in Brazil, is endemic for cutaneous and visceral leishmaniases and is frequently visited by tourists from different parts of the world. Since the complex epidemiology of leishmaniases demands local studies, the goal of this study was to investigate the phlebotomine sand fly fauna and leishmaniases transmission in Ilha Grande, an ecotourism area of Angra dos Reis municipality.MethodsSand fly fauna was sampled in three monitoring stations using HP light traps in domiciles, peridomiciles and forests. Species abundance was evaluated by the Index of Species Abundance. A Leishmania natural infection survey was done using multiplex PCR and dot blot hybridization.ResultsDuring 15 consecutive months of sand fly monitoring, 1093 specimens from 16 species were captured. The potential leishmaniases vectors found were Lutzomyia (Nyssomyia) intermedia, L. migonei, L. (N.) flaviscutellata, L. (Psychodopygus) ayrozai and L. (Lutzomyia) longipalpis. Five species were new records in Ilha Grande: L. (Sciopemyia) microps, L. termitophila, L. firmatoi, L. rupicola and L. (P.) ayrozai. Higher species richness was found inside forest areas, although potential leishmaniases vectors were present in deforested areas, peridomiciles and inside houses. Lutzomyia (N.) intermedia and L. migonei were the most abundant species. Females of L. migonei showed a high rate (10.3%) of natural infection by Leishmania (Viannia) sp., probably Leishmania (V.) braziliensis.ConclusionsThe detection of leishmaniases transmission and potential vectors in Ilha Grande is of public health concern, especially because tourists are frequently visiting the island. Besides reinforcing the epidemiological importance of L. (N.) intermedia in Rio de Janeiro State, the role of L. migonei in cutaneous leishmaniasis transmission is highlighted with its high rate of Leishmania natural infection. The finding of L. (L.) longipalpis confirmed the human autochthonous case of visceral leishmaniasis from the island. The presence of L. (N.) flaviscutellata in peridomestic areas is also an important finding, since the species is involved in the transmission of diffuse cutaneous leishmaniasis. Health education practices directed to the local community and tourists are important control actions that can be taken in Ilha Grande to reduce the burden of leishmaniases.

Introduction:The sand fly, Lutzomyia longipalpis, is the main vector of Leishmania infantum in the Americas, primarily occurring in areas of apparent anthropomorphic modifications in several regions of Brazil. Methods. Sand flies were captured using light traps. Results: Out of all captured species, Lu. longipalpis numbers had increased within the park. Conclusions: We report the occurrence of Lu. longipalpis in an area of Atlantic Forest, possibly representing the first sylvatic population of Lu. longipalpis in an area absent of peridomestic captures, but with the risk of L. infantum transmission in the areas of Niterói and Maricá.

Introduction:The presence of American cutaneous leishmaniasis (ACL) in the communities of the Campus FIOCRUZ Mata Atlântica (CFMA) in the City of Rio de Janeiro initiated the investigation of the Phlebotominae fauna in the Atlantic Forest to determine the occurrence of putative ACL vectors associated with the enzootic cycle. Methods: For 24 consecutive months, sand fl ies were captured inside the forest and in the border area near the communities. Results: The following sand fl y species were identifi ed: Brumptomyia brumpti, Brumptomyia cunhai, Brumptomyia nitzulescui, Lutzomyia edwardsi, Lutzomyia pelloni, and Lutzomyia quinquefer. Other identifi ed sand fl y vectors, such as Lutzomyia intermedia (the predominant species), Lutzomyia migonei, Lutzomyia whitmani, Lutzomyia fi scheri, and Lutzomyia hirsuta hirsuta, are associated with ACL transmission, and the vector for American visceral leishmaniases (AVL), Lutzomyia longipalpis, was also found. Conclusions: All sand fl y vectors were found in both studied environments except for Lutzomyia whitmani, which was only identifi ed in the forest. This study represents the fi rst identifi cation of Lutzomyia longipalpis in the CFMA, and the epidemiological implications are discussed.Keywords: American Cutaneous Leishmaniasis. American Visceral Leishmaniasis. Rio de Janeiro City. Lutzomyia longipalpis. Lutzomyia intermedia.All the Brazilian states currently report human cases of American cutaneous leishmaniasis (ACL) in a significant number of municipalities. ACL is transmitted from a complex parasitosis that involves multiple parasites, vectors and vertebrate hosts in restricted ecologic niches (1) .In the State of Rio de Janeiro, the occurrence of ACL has been recorded since the beginning of the previous century. In the last few decades, ACL has been observed in epidemic outbreaks in different municipalities, including the economically developed City of Rio de Janeiro. In the capital of the state, the disease is particularly prevalent in the western areas (2) of the region around the Pedra Branca massif in the neighborhood of Jacarepaguá where the Campus FIOCRUZ da Mata Atlântica (CFMA) is located (3) .Approximately 55% of the CFMA consists of the Pedra Branca State Park, a preserved environmental area of the Atlantic Forest. Six communities comprise the remaining 45% of the CFMA: Vianna do Castelo, Nossa Senhora dos Remédios, Faixa Azul, Fincão, Sampaio Correa, and Caminho da Cachoeira. Cases of ACL from these communities historically represent approximately 8% of all human ACL cases recorded in Rio de Janeiro with evidence of intra-and peridomiciliary transmission (3) . The current study aims to improve the understanding of the eco-epidemiology of ACL at the CFMA by studying the Phlebotominae fauna, potential vectors in the forest environment associated with a zoonotic cycle, and the interface between ACL and the community of Caminho da Cachoeira. METHODS Study areaThe CFMA is located in part of the former hospice Colonia Juliano Moreira in the neighbor...
