Serological survey of Leishmaniainfection in blood donors in Salvador, Northeastern Brazil
BACKGROUND Visceral Leishmaniasis is endemic to Brazil, where it is caused by Leishmania infantum (syn. Leishmania chagasi). Following parasite inoculation, individuals may experience asymptomatic infection, raising the possibility of parasite transmission through the transfusion of contaminated blood products. In the present work, we evaluated the prevalence of asymptomatic Leishmania infectio...

Several phlebotomine sand fly species have been regarded as putative or proven vectors of parasites of the genus Leishmania in Brazil, but data for the northeastern region remains incipient. In this study, a total of 600 phlebotomine sand flies were grouped in pools of 10 specimens each and tested by a Leishmania genus-specific PCR and by a PCR targeting Leishmania (Leishmania) infantum. Fourte...
متن کاملStrategies for reducing the risk of transfusion-transmitted leishmaniasis in an area endemic for Leishmania infantum: a patient- and donor-targeted approach.
BACKGROUND In the Balearic Islands, as in other areas of the Mediterranean basin, there is a significant proportion of asymptomatic Leishmania (L.) infantum-infected blood donors, who may represent an important threat to transfusion safety. The Balearic Islands blood bank, located in an area endemic for L. infantum, carried out a study of donors and patients to investigate the impact of this in...
متن کاملCharacterization of Leishmania (L.) infantum chagasi in visceral leishmaniasis associated with hiv co-infection in Northeastern Brazil
Visceral leishmaniasis, associated with HIV/AIDS coinfection, is becoming a more aggressive disease, complicating an accurate prognosis. A 21-year-old HIV-positive female presenting with clinical features of visceral leishmaniasis was enrolled in this study. Bone marrow cytology, Novy-MacNeal-Nicolle culture and kDNA PCR of peripheral blood were all positive. Typing methods, multilocus enzyme e...
متن کاملOccurrence of Leishmania infantum parasitemia in asymptomatic blood donors living in an area of endemicity in southern France.
Visceral leishmaniosis (VL) due to Leishmania infantum (L. chagasi) is a lethal disease if untreated, but asymptomatic L. infantum infections have been reported previously. A better understanding of parasite transmission, dissemination, and survival in the human host is needed. The purpose of this study was to assess whether L. infantum circulated in peripheral blood of subjects with no history...
