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
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
application of spatio-temporal scan statistics for the detection of areas with increased risk for american visceral leishmaniasis in the state of bahia, brazil.mirroring the global increase of registered cases of american visceral leishmaniasis (avl), this infection has become a growing public health problem in brazil during the last several years. as the traditional approach to control employed by the governmental health agencies has failed to reduce the incidence and epidemic outbreaks of this illness, we propose a re-evaluation of the national strategy of intervention and monitoring. our thinking is based on a series of spatio-temporal scan statisti ...200718686261
natural infection of the opossum didelphis albiventris (marsupialia, didelphidae) with leishmania donovani, in brazil.an opossum, didelphis albiventris, from jacobina, bahia state, was found naturally infected with leishmania donovani, being the first non-canid wild mammal to be detected with the agent of kala-azar in the new world.19846533423
remote sensing and geographic information systems and risk of american visceral leishmaniasis in bahia, brazil.the spatial distribution of american visceral leishmaniasis (vl) was studied within the context of the environmental characteristics of northwest bahia state in brazil during an epidemic year. geographic information systems (gis) and remote sensing (rs) were used to characterize the landscape epidemiology of vl in order to identify and map high risk areas and endemic zones in a northwestern bahia study area. normalized difference vegetation index (ndvi) was shown to be one of the most important ...200516044686
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 ...19863080918
leishmaniasis in brazil. xxii: characterization of leishmania from man, dogs and the sandfly lutzomyia longipalpis (lutz & neiva, 1912) isolated during an outbreak of visceral leishmaniasis in santarém, pará state.during epidemiological studies on an outbreak of visceral leishmaniasis in santarém, pará state, north brazil, isolates of leishmania from two children, three dogs and six naturally infected specimens of the sandfly lutzomyia longipalpis were compared, biochemically, by starch-gel enzyme electrophoresis. they have proved to be indistinguishable from each other, and from a reference strain of leishmania chagasi cunha & chagas, 1937 from a case of human visceral leishmaniasis from bahia state, nor ...19863726975
