| evaluation of the micro enzyme-linked immunosorbent assay (elisa) for antibodies in american visceral leishmaniasis: antigen selection for detection of infection-specific responses. | this study was designed to evaluate the elisa for diagnosis of american visceral leishmaniasis (avl) using antigen prepared from different leishmania isolates and from a strain of trypanosoma cruzi. two leishmania donovani chagasi isolates from bahia and maranhão (both states of northern brazil), one l. donovani from sudan, one l. mexicana amazonensis isolate, and one t. cruzi isolate were used. a total of 375 sera were tested, including 119 from avl patients, 96 from nonleishmaniasis hospitaliz ... | 1986 | 3080918 |
| 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 ... | 1982 | 7164150 |
| 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 ... | 1987 | 3826486 |
