Parasitic culture of buffy coat for diagnosis of visceral leishmaniasis in human immunodeficiency virus-infected patients

Abstract

Two samples of buffy coat from the peripheral blood of 25 human immunodeficiency virus-positive patients with proven visceral leishmaniasis, as determined with a bone marrow aspirate (stain and culture), were cultured onto Schneider's and Novy-McNeal-Nicolle media. Hemoculture positivity was 67%. The average growing time was 10 days. This is an easy, noninvasive, and sensitive technique.
