cutaneous leishmaniasis of man due to leishmania (viannia) shawi lainson, de souza, póvoa, ishikawa & silveira, in pará state, brazil.leishmania (viannia) shawi lainson, braga, de souza, póvoa, ishikawa & silveira, 1989, was originally recorded from monkeys (cebus apella and chiropotes satanas), sloths (choloepus didactylus and bradypus tridactylus) and coatis (nasua nasua) and the sandfly, lutzomyia whitmani. with a panel of leishmania specific monoclonal antibodies, it was found that 30.5% of the leishmania strains from patients, who had contracted cutaneous leishmaniasis in pará state, were similar, but not identical to l. ...19911822654
variation between geographical populations of lutzomyia (nyssomyia) whitmani (antunes & coutinho, 1939) sensu lato (diptera:psychodidae:phlebotominae) in brazil.phylogenetic analysis of morphometric and biological characters indicated that there are two distinct forms of lutzomyia whitmani in brazil: one is present both north and south of the river amazonas in the state of pará while the other occurs in northeast brazil, in the state of ceará, and further south, including the type locality in state of bahia. the amazonian form is reportedly neither strongly anthropophilic nor synanthropic, and it is the vector of leishmania shawi; whereas the southern f ...19968734947
characterization in vivo and in vitro of a strain of leishmania (viannia) shawi from the amazon region.the present study analyses complement resistance, cell surface carbohydrates expression, lipidic composition and morphology in vivo and in vitro, of leishmania (viannia) shawi, a parasite identified in the amazon region, pará state, in 1989. we demonstrated that promastigotes in the stationary (stat) growth phase are more resistant to complement lysis than in the logarithmic (log) growth phase. ultrastructural analyses and imidazol technique showed accumulation of lipids in stat growth phase pro ...200919567230
phenotypic characterization of leishmania spp. causing cutaneous leishmaniasis in the lower amazon region, western pará state, brazil, reveals a putative hybrid parasite, leishmania (viannia) guyanensis × leishmania (viannia) shawi shawi.we phenotypically characterized 43 leishmanial parasites from cutaneous leishmaniasis by isoenzyme electrophoresis and the indirect immunofluorescence antibody test (23 mcabs). identifications revealed 11 (25.6%) strains of leishmania (v.) braziliensis, 4 (9.3%) of l. (v.) shawi shawi, 7 (16.3%) of l. (v.) shawi santarensis, 6 (13.9%) of l. (v.) guyanensis and l. (v.) lainsoni, 2 (4.7%) of l. (l.) amazonensis, and 7 (16.3%) of a putative hybrid parasite, l. (v.) guyanensis/l. (v.) shawi shawi. m ...201425083790
