cutaneous leishmaniasis in western venezuela caused by infection with leishmania venezuelensis and l. braziliensis variants.between 1975 and 1987, epidemiological studies were carried out in several rural and urban communities in the central part of western venezuela, especially in the state of lara. 115 positive cultures were obtained from human cases and identified by their reactivity patterns to a cross-panel of specific monoclonal antibodies using a radioimmune binding assay; 53 were leishmania venezuelensis and 62 were l. braziliensis. most of these stocks were also characterized by isoenzyme electrophoresis, wh ...19921440772
vectors of cutaneous leishmaniasis in north-central entomological survey was undertaken from january 1991 to february 1992 in el ingenio, miranda state, venezuela, an endemic area of cutaneous leishmaniasis: prevalence of 10.7 cases per 100,000 inhabitants. a total of 4863 female sandflies (phlebotominae) of fourteen species were collected in shannon traps, then dissected and examined for leishmanial infections. lutzomyia ovallesi (85.4%) and lu. gomezi (11.2%) were the predominant anthropophilic species of sandfly. fifty-one (1.19%) lu.ovalle ...19947841486
abundance of lutzomyia ovallesi but not lu. gomezi (diptera: psychodidae) correlated with cutaneous leishmaniasis incidence in north-central north-central venezuela lutzomyia gomezi and lu. ovallesi are the main endophilic/anthropophilic species of phlebotomine sandflies implicated as vectors of cutaneous leishmaniasis (cl). lutzomyia ovallesi has been found infected with leishmania braziliensis (1.2%) and less often with le. mexicana (0.07%), while le. braziliensis infections have also been found in lu. gomezi (0.47%). we investigated population densities of these sandflies using two sampling methods with four series of collectio ...19989622364
