[cutaneous leishmaniasis in amazonia: isolation of leishmania (viannia) lainsoni from the rodent agouti paca (rodentia: dasyproctidae), in the state of pará, brazil].the isolation of leishmania (v.) lainsoni is recorded for the first time from a wild animal, the rodent agouti paca (rodentia: dasyproctidae), from pará state, north brazil. isolates of the parasite were made from apparently normal skin of 3 specimens of this rodent captured on the island of tocantins, in the municipality of tucuruí, an area subsequently flooded in the formation of the lake associated with the tucuruí hydroelectric dam. no isolations were made from the viscera. identification of ...19911843391
lutzomyia (nyssomyia) whitmani s.l . (antunes & coutinho, 1939)(diptera: psychodidae: phlebotominae): geographical distribution and the epidemiology of american cutaneous leishmaniasis in brazil--mini-review.the aim of the present study, in view of the widespread geographical distribution of lutzomyia (nyssomyia) whitmani s.l. in brazil, in close association with the regions of transmission of leishmania (viannia) braziliensis and l. (v.) shawi, is to investigate the distribution of this sand fly species and american cutaneous leishmaniasis (acl) in relationship to vegetation and landscape ecology throughout brazil. thematic maps were elaborated by the mapinfo programme, giving information on the sp ...200717426877
the phlebotomine fauna (diptera: psychodidae) of guaraí, state of tocantins, with an emphasis on the putative vectors of american cutaneous leishmaniasis in rural settlement and periurban areas.phlebotomine sandflies were captured in rural settlement and periurban areas of the municipality of guaraí in the state of tocantins (to), an endemic area of american cutaneous leishmaniasis (acl). forty-three phlebotomine species were identified, nine of which have already been recognised as acl vectors. eleven species were recorded for the first time in to. nyssomyia whitmani was the most abundant species, followed by evandromyia bourrouli, nyssomyia antunesi and psychodopygus complexus. the s ...023903972
identification and biological characterization of leishmania (viannia) guyanensis isolated from a patient with tegumentary leishmaniasis in goiás, a nonendemic area for this species in brazil.the aim of this study was to characterize clinical field isolates of leishmania spp. obtained from patients with american tegumentary leishmaniasis (atl) who live in goiás state, brazil. the presumed areas of infection were in goiás, tocantins, and pará states. three isolates of parasites were identified as l. (viannia) braziliensis and one as l. (v.) guyanensis. the in vitro growth profiles were found to be similar for all parasites. nevertheless, in c57bl/6 mice, l. (v.) guyanensis infection w ...201526583102
aspects on the ecology of phlebotomine sand flies (diptera: psychodidae) from guaraí, state of tocantins, brazil, endemic area for american cutaneous brazil, american cutaneous leishmaniasis (acl) ecology involves a diversity of leishmania species transmitted by different sand fly species. workers involved in agricultural activities are those mainly affected by acl in some regions from tocantins state (to), brazil, where the disease can be established in new settlements. the objective of this study was to examine the seasonal and hourly frequency of sand fly species, focusing on the potential vectors of acl, in a settlement in guaraí (to), ...201728082651
