<em>Plasmodium falciparum</em> sexual commitment rate variation among clinical isolates and diverse laboratory-adapted lines (Publications)
Asexual blood-stage malaria parasites must produce sexual progeny to infect mosquitoes. It is important to understand the scope and causes of intraspecific variation in sexual commitment rates, particularly [...] variation of this key reproductive trait that likely affects transmission. IMPORTANCE Only sexual-stage malaria parasites are transmitted from human blood to mosquitoes. Thus, it is vital to understand variations

insecticide-treated nets (ITNs) delivered to malaria-endemic countries is conducted by measuring physiochemical parameters, but not bioefficacy against malaria mosquitoes. This study explored utility of
Socio-cultural factors explaining timely and appropriate use of health facilities for degedege in south-eastern Tanzania (Publications)
BACKGROUND: Convulsions is one of the key signs of severe malaria among children under five years of age, potentially leading to serious complications or death. Several studies of care-seeking behaviour [...] that facilities did not provide diagnosis. CONCLUSION: The findings from this sample from a highly malaria-endemic area give support to the more recent studies showing that children with convulsions are more
Comparison of molecular quantification of <em>Plasmodium falciparum</em> gametocytes by <em>Pfs</em>25 qRT-PCR and QT-NASBA in relation to mosquito... (Publications)
BACKGROUND: Quantifying gametocyte densities in natural malaria infections is important to estimate malaria transmission potential. Two molecular methods (Pfs25 mRNA quantitative reverse transcriptase

requires further investigation in natural infections where it is under immune selection. IMPORTANCE: Malaria parasites in the blood are remarkably variable, able to switch antigenic targets so they may survive [...] developed specific immune responses. This is one of the challenges in developing vaccines against malaria. MSPDBL2 is a target of naturally acquired immunity expressed in minority proportions of schizonts
