epidemiological studies on american leishmaniasis in ceará state, brazil. molecular characterization of the leishmania isolates.two methods of molecular characterization, using monoclonal antibodies and enzyme electrophoresis, were employed in the identification of 36 stocks of leishmania isolated from human and canine cases of american visceral (avl) and cutaneous (acl) leishmaniases in the northern part of ceará state, brazil. molecular homogeneous strains of leishmania donovani (chagasi) isolated from both human and canine hosts were detected in 14 municipalities. two more parasite species, l. braziliensis braziliensi ...19883256276
identification and distribution of new world leishmania species characterized by serodeme analysis using monoclonal antibodies.five hundred thirty stocks of leishmania isolated from human and domestic and wild reservoir hosts, representing a wide geographic distribution of endemic foci of american cutaneous (acl) and visceral leishmaniases (avl) were characterized and identified at species and/or subspecies levels based on their reactivity to a cross-panel of specific monoclonal antibodies using a radioimmune binding assay. this study confirms and extends our preliminary results on the high specificity of some of these ...19873826486
[cutaneous parasitism by leishmania (leishmania) chagasi during south american visceral leishmaniasis].eighteen patients from the northeastern brazilian state of ceara with proven kala-azar were studied for evidence of skin parasitism: two had ulcerative or papular skin lesions and 16 had clinically normal skin. punch biopsies (3 mm) of intact paraspinal subscapular skin were performed on all patients; in those with papular or ulcerative lesions biopsies also were taken from an active site. one of each of the subscapsular biopsies and half of each biopsy from an active lesion were studied; the ot ...19938353466
leishmaniasis in brazil: xviii. further evidence incriminating the fox cerdocyon thous (l) as a reservoir of amazonian visceral leishmaniasis.major endemic areas of visceral leishmaniasis in brazil are located in the drier, poorly forested regions, principally in the northeastern states such as ceará and bahia. cases of the human disease in the amazon region are rare, very sporadic, and seldom present opportunities for epidemiological study. following the report of a fatal case near salvaterra, the island of marajó, pará state, a preliminary investigation has resulted in the isolation of a parasite regarded as leishmania donovani chag ...19827164150
leishmaniasis in brazil. xix: visceral leishmaniasis in the amazon region, and the presence of lutzomyia longipalpis on the island of marajó, pará state.sporadic cases of visceral leishmaniasis in amazonian brazil appear limited to pará state, in the lower amazon valley and principally near the atlantic coast. the fox cerdocyon thous (l.) has been incriminated as a natural host of the causative parasite, leishmania donovani chagasi, but past doubts have existed over the identification of the most likely vector as lutzomyia (lutzomyia) longipalpis (lutz & neiva, 1912). investigations on two of five recent cases of visceral leishmaniasis of man in ...19836623589
