“…An enzootic cycle of VL and accidental transmission to humans was suggested for this sand fly vector . There are similar reports from San Vicente Ferrer in the State of Pernambuco, Brazil, and the natural infection of this species by L. (L.) infantum chagasi has been documented (CARVALHO et al, 2007(CARVALHO et al, , 2010.…”

“…A similar pattern has been demonstrated in San Vicente Férrer, State of Pernambuco, in northeastern Brazil. In this study, the natural infection of L. migonei with L. (L.) infantum chagasi was documented, highlighting the potential role of this vector for parasite transmission in these areas (CARVALHO et al, 2010). The objective of this study was to gain insight into the transmission of L. infantum in Fortaleza by studying the ecology of L. longipalpis and L. migonei through the evaluation of entomological indicators of VL and discussing whether these sympatric species may share the role as vectors for L. infantum in urban areas.…”

The main vector for visceral leishmaniasis (VL) in Brazil is Lutzomyia longipalpis. However, the absence of L. longipalpis in a region of autochthonous VL demonstrates the participation of other species in the transmission of the parasite. Studies conducted in La Banda, Argentina, and São Vicente Férrer, Pernambuco State, Brazil, have correlated the absence of L. longipalpis and the presence of L. migonei with autochthonous cases of VL. In São Vicente Férrer, Pernambuco, there was evidence for the natural infection of L. migonei with Leishmania infantum chagasi. Thus, the objective of this work was to assess the ecology of the sand flies L. longipalpis and L. migonei in Fortaleza, an endemic area for VL. Insect capture was conducted at 22 sampling points distributed across four regions of Fortaleza. In total, 32,403 sand flies were captured; of these, 18,166 (56%) were identified as L. longipalpis and 14,237 (44%) as L. migonei. There were significant density differences found between the vectors at each sampling site (indoors and outdoors) (p <0.0001). These findings confirm that L. migonei and L. longipalpis are distributed throughout Fortaleza, where they have adapted to an indoor environment, and suggest that L. migonei may share the role as a vector with L. longipalpis in the transmission of VL in Fortaleza.Keywords: Lutzomyia longipalpis, Lutzomyia migonei, visceral leishmaniasis, Fortaleza.

The present study reports the first outbreak of autochthonous canine visceral leishmaniasis in Florianópolis, Santa Catarina, southern Brazil. Following the report of two cases of CVL, the Control Center of Zoonotic Diseases conducted a serological survey by ELISA and IFAT assays in seven districts of the Santa Catarina Island. Eleven seropositive dogs of autochthonous transmission were used in the present study. Infection by Leishmania sp. was confirmed by parasitological examination of bone marrow, liver, spleen and lymph nodes, culture in Schneider's medium and PCR. Leishmania sp. isolates were characterized by PCR-RFLP and hybridization with specific probes, allowing for the identification of Leishmania infantum. Autochthonous transmission of this disease in an area with high tourist traffic presents a major public health concern and signifies the emergence of an important zoonosis in southern Brazil. Therefore, the implementation of surveillance and control measures is imperative to prevent the spread of the disease among the canine population as well as transmission to the human population. infecção por Leishmania sp. foi realizada pelo exame parasitológico da medula óssea, fígado, baço e linfonodos, cultura em meio Schneider e PCR. Os isolados de Leishmania sp. foram caracterizados por PCR-RFLP e hibridação com sondas específicas, permitindo a identificação de Leishmania infantum. A transmissão autóctone da LCV em uma área com grande fluxo turístico como Florianópolis representa um preocupante risco à saúde pública e o surgimento de uma importante zoonose no sul do Brasil. Neste contexto, a implementação de medidas de vigilância e controle da doença são fundamentais para evitar a propagação da doença entre a população canina, bem como a transmissão para a população humana.TERMOS DE INDEXAÇÃO: Leishmaniose visceral canina, Leishmania infantum, zoonose, doenças negligenciadas, saúde pública.

“…Aguiar et al 21 highlighted the high anthropophily of L. migonei, its adaptability to modified environments, and its low occurrence in wild environments, which also was observed in the study area. Moreover, the vector role of L. migonei has been suggested in areas of autochthonous cases of VL where L. longipalpis, the classic vector of Leishmania (Leishmania) infantum, is not found 6,22,23 . Lutzomyia complexa, the predominant species in forest remnants, which presents considerable distribution in Pernambuco, also has been reported in Recife, Paudalho (northern rainforest area) and Amaraji (southern rainforest area) 24 .…”

Introduction:In the last decades, a considerable geographic expansion of the leishmaniases in all regions of Brazil has been observed. The present study was carried out to identify the composition of the phlebotomine sandfly fauna and verify the seasonal variation of the main species after environmental changes occurred in São Vicente Férrer Municipality, State of Pernambuco, Brazil. Methods: Captures were carried out during four consecutive nights of each month using Centers for Disease Control and Prevention light traps from September 2009 to September 2010. The correlation between the number of phlebotomine sandflies captured and climatic factors (temperature and rainfall) was evaluated. Results: A total of 13,872 specimens belonging to 20 species were captured, of which, 6,247 (45%) were females, and 7,625 (55%) were males. Lutzomyia migonei was the most abundant species with 9,964 (71.8%) specimens, being predominant in the intradomicile and peridomicile areas with 108 (86.4%) and 9,746 (97%), respectively. In the forest remnants, Lutzomyia complexa 2,395 (65%) and Lutzomyia sordellii 770 (20.8%) predominated. The correlation analysis between the total number of sandflies captured and climatic factors did not show a significant influence on population density. Conclusions: The high abundance of Lutzomyia migonei and Lutzomyia complexa indicates the possibility of new cases of cutaneous leishmaniasis (CL). Keywords: Leishmaniases. Sandflies. São Vicente Férrer. RESUMO Introdução: Nas últimas décadas tem se observado uma considerável expansão geográfica das leishmanioses em todas as regiões do Brasil. O presente estudo foi realizado para identificar a fauna de flebotomíneos e verificar a sazonalidade das principais espécies após mudanças ambientais ocorridas no município de São Vicente Férrer, Estado de Pernambuco, Brasil. Métodos: As capturas foram realizadas durante quatro noites consecutivas por mês usando armadilhas luminosas CDC, no período de setembro de 2009 a setembro de 2010. A correlação entre o número de flebotomíneos capturados e fatores climáticos (temperatura e umidade) foi avaliada. Resultados: Foi capturado um total de 13.872 espécimes pertencentes a 20 espécies, sendo 6.247 (45%) fêmeas e 7.625 (55%) machos. Lutzomyia migonei foi a espécie mais abundante com 9.964 (71,8%) espécimes, sendo predominante no intradomicílio 108 (86,4%) e peridomicílio 9.746 (97%). Nos resquícios de mata primária, predominaram Lutzomyia complexa 2.395 (65%) e Lutzomyia sordellii 770 (20,8%). A análise de correlação entre o número total de flebotomíneos capturados e os fatores climáticos não mostrou uma influência significativa na densidade da população. Conclusões: A elevada abundância de Lutzomyia migonei e Lutzomyia complexa indica a possibilidade de novos casos de leishmaniose cutânea (LC). Palavras-chaves:Leishmanioses. Flebotomíneos.
