“…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.…”

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.

“…In an area of American visceral leishmaniasis in Pernambuco state in the Brazilian Northeastern region, Carvalho et al 10 pointed to Mg. migonei as a possible vector of L. i. chagasi, in spite of not having found females infected with L. i. chagasi. For identification of this insect as a vector, the authors took into account mainly their abundance in the intra and peri domiciliary environments of residences in which human cases had occurred.…”

“…Some authors support the participation of other sand fly species in the transmission of American visceral leishmaniasis 10 , based on their coincidental distribution with the disease. There are also those authors that defend the participation of other arthropods in American visceral leishmaniasis transmission, based on findings of natural infection in fleas 11 and ticks 12 .…”

American visceral leishmaniasis dissociated from Lutzomyia longipalpis (Diptera, Psychodidae) in the State of Espírito Santo, Brazil

The occurrence of American visceral leishmaniasis in the State of Espírito Santo, Brazil has always been associated with the presence of the Lutzomyia longipalpis vector. The geographic distribution of this vector in this state is related to the presence of specific geoclimatic characteristics, such as a dry climate, low elevations (< 450m), steep slopes and rocky outcrops. The occurrence of human autochthonous cases of American visceral leishmaniasis in municipalities without these geoclimatic characteristics justifies the present study and our main goal was to test the association between the occurrence of American visceral leishmaniasis and the presence of the Lu. longipalpis. Sand flies were captured monthly from July 2006 to August 2007 using Shannon and CDC traps in two municipalities with records of autochthonous American visceral leishmaniasis and one with no record. We captured 13,112 sand flies, but no Lu. longipalpis was found. The absence of Lu. longipalpis and the possible role of another American visceral leishmaniasis vector in these localities were discussed.

“…They are also notable due to their adaptability to live in a great variety of environmental conditions and their capability to survive for long periods of time without feeding (DANTAS-TORRES, 2008a '' S and 35° 29' 29'' W). This municipality is located in the agreste region of Pernambuco but its environmental features are similar to those seen in the Atlantic rain forest region (CARVALHO et al, 2007). From 2 to 6 June 2008, all but two dogs living in the aforementioned rural community were physically examined for the presence of ectoparasites.…”

“…The present results indicate that dogs from São Vicente Férrer are potentially exposed to vector-borne pathogens. Interestingly, canine visceral leishmaniasis is endemic in São Vicente Férrer, but the presence of Lutzomyia longipalpis has not been confirmed (CARVALHO et al, 2007). Moreover, Leishmania-like forms have been reported in R. sanguineus ticks collected from dogs living in this municipality (SILVA et al, 2007).…”

This article presents the results of a study on ectoparasites infesting rural dogs in Pernambuco, northeastern Brazil. Forty-one dogs from a rural community of Pernambuco were examined and 70.7% were infested by ectoparasites. The prevalence rates of infestation by ticks, fleas, and lice were 58.5, 43.9 and 22%, respectively. Of 24 dogs parasitized by ticks, 15 were exclusively infested by Rhipicephalus sanguineus (Latreille) (32 females, 66 males, 9 nymphs; prevalence, 48.8%; mean intensity, 5.4), four by Amblyomma ovale Koch (33 females, 19 males; prevalence, 22%; mean intensity, 5.8), and five were coinfested by both species. Ctenocephalides felis felis (Bouché) (25 females, 8 males; prevalence, 43.9%; mean intensity, 1.9) and Heterodoxus spiniger (Enderlein) (16 females, 11 males, 10 nymphs; prevalence, 22%; mean intensity, 4.1) were the only species of flea and louse identified. Tick infestation was more frequent than flea or lice infestations (p < 0.05). No statistical difference was found by sex and age group of the dogs studied and prevalence of infestation. Overall, 48.8% (20/41) of the dogs were infested by more than one ectoparasite species.Keywords: Ixodida, Siphonaptera, Phthiraptera, Brazil, dog. ResumoO presente artigo apresenta os resultados de um estudo sobre os ectoparasitos que infestam cães rurais em Pernambuco, Nordeste do Brasil. Quarenta e um cães de uma comunidade rural de Pernambuco foram examinados e 70,7% estavam infestados por ectoparasitos. As taxas de prevalência de infestação por carrapatos, pulgas e piolhos foram 58,5, 43,9 e 22%, respectivamente. Dos 24 cães parasitados por carrapatos, 15 estavam exclusivamente infestados por Rhipicephalus sanguineus (Latreille) (32 fêmeas, 66 machos, 9 ninfas; prevalência, 48,8%; intensidade média, 5,4), quatro por Amblyomma ovale Koch (33 fêmeas, 19 machos; prevalência, 22%; intensidade média, 5,8), e cinco estavam co-infestados por ambas as espécies. Ctenocephalides felis felis (Bouché) (25 fêmeas, 8 machos; prevalência, 43,9%; intensidade média, 1,9) e Heterodoxus spiniger (Enderlein) (16 fêmeas, 11 machos, 10 ninfas; prevalência, 22%; intensidade média, 4,1) foram as únicas espécies de pulga e piolho identificadas. A infestação por carrapatos foi mais frequente que as infestações por pulgas ou piolhos (p < 0.05). Não houve diferença estatística em relação ao sexo e grupo etário dos cães e a prevalência de infestação. No geral, 48,8% (20/41) dos cães estavam infestados por mais de uma espécie de ectoparasito.
