Two hundred fourteen adult individuals were selected for studies to assess their immune responses against the malaria vaccine candidate ring-infected erythrocyte [...] to be age dependent. Total anti-RESA IgG antibodies were not correlated with protection against malaria as measured by parasite prevalence, parasite density, or health center attendance. In contrast,

We assessed health worker malaria treatment practices after [...] received training on how to perform RDTs for patients 5 years of age or older with fever or suspected malaria. Children < 5 years of age were to be treated empirically per national guidelines. Among the 30,195 [...] 195 patients seen at these 12 health facilities, 10,737 (35.6%) were...
Quality assurance of rapid diagnostic tests for malaria in routine patient care in rural Tanzania (Publications)
Histidine-rich protein II (HRP2)-based malaria rapid diagnostic tests (RDTs) have shown high sensitivity and specificity for detecting Plasmodium falciparum malaria in a variety of study settings. However [...] their use in field settings. We evaluated sensitivity and specificity of RDTs during routine use for malaria case management in peripheral health facilities. From December 2007 to October 2008, HRP2-based ParaHIT-f [...] thick blood smear. Job aids, Integrated Management of Childhood...

IgG, IgG1 and IgG3 responses generally increased [...] required for protection from malaria. Our results suggest that in...
Histone methyltransferase inhibitors are orally bioavailable, fast acting molecules with activity against different species causing malaria in humans (Publications)
antimalarials are under continuous threat due to the relentless development of drug resistance by malaria parasites. We previously reported promising in vitro parasite killing activity with the histone
