Characterization and Classification of Leishmanial Parasites from Humans, Wild Mammals, and Sand Flies in the Amazon Region of Brazil

Fauna de flebotomíneos (Diptera: Psychodidae) em um foco de leishmaniose tegumentar americana na área periurbana de Manaus, Estado do Amazonas

“…Para o gênero Psychodopygus destaca-se Psychodopygus davisi, cuja distribuição geográfica abrange toda a Amazônia, é uma espécie envolvida na transmissão de Leishmania naiffi, da qual também já foi isolada Leishmania (Viannia) braziliensis 19 A importância do padrão periflorestal de transmissão na Cidade de Manaus já foi ressaltada anteriormente 2 10 . Guerra e cols 23 sugerem que na localidade do estudo ocorrem dois diferentes padrões epidemiológicos de transmissão de LTA.…”

Phlebotominae sand flies (Diptera: Psychodidae): potential vectors of American cutaneous leishmaniasis agents in the area associated with the Santo Antônio Hydroelectric System in Western Amazonian Brazil

“…The anthropophilic behavior and widespread distribution of these insects in the Amazon basin (25) and previous records of natural Leishmania infections with this species suggest that this species is a potential vector of ACL agents in the studied region. This species has been shown to carry L. (V.) braziliensis and L. (V.) naiffi Lainson and Shaw in Serra dos Carajás (26) (Southern State of Pará, Brazil) and L. (V.) braziliensis in State of Rondônia (14) (27) . Recently, two females of this species from the area associated with the Belo Monte Hydroelectric System in State of Pará were found to carry peripylarian Leishmania -like fl agellates (unpublished observations).…”

First human cases of Leishmania (Viannia) naiffi infection in Ecuador and identification of its suspected vector species

“…Leishmania (V.) naiffi was originally described as a parasite of armadillos in the Amazonian area of Brazil . Although it is less common, human infection with L. (V.) naiffi resulting in CL has been reported in Brazil (Lainson et al, 1990;Naiff et al, 1991;Grimaldi et al, 1991;Felinto de Brito et al, 2012) and other Latin American countries such as French Guiana, Martinique, Guadeloupe, and…”
