The burden and duration of asymptomatic malaria infections were measured in residents of the malaria endemic village of Gonoa, Madang Province, Papua New Guinea. Plasmodium falciparum, P. vivax and P. malariae infections in people aged 4 years to adulthood were compared. Frequent sampling at 3-day intervals for up to 61 days allowed assessment of individual episodes of infection. Statistical as...

We reanalyzed a dataset consisting of approximately 10,700 crepuscular and night-biting female mosquitoes (Culicidae) collected over 12 mo in the canopy and understorey of primary Amazonian rain forest. We investigate whether vertical habitat stratification and rainfall modified major ecological parameters of this mosquito ensemble, combining descriptive and hypothesis-testing statistics with s...

A total of 460 Anopheles funestus s.l. was collected inside human dwellings in Mwea, central Kenya. Of the 414 specimens that were positively identified, 1 was Anopheles leesoni and the others were Anopheles parensis. None of the 373 specimens tested were positive for Plasmodium falciparum or Plasmodium malariae sporozoites by enzyme-linked immunosorbent assay (ELISA). Of the 139 ELISA blood-me...

INTRODUCTION In the past malaria rapid diagnostic tests (RDTs) for self-diagnosis by travelers were considered suboptimal due to poor performance. Nowadays RDTs for self-diagnosis are marketed and available through the internet. The present study assessed RDT products marketed for self-diagnosis for diagnostic accuracy and quality of labeling, content and instructions for use (IFU). METHODS D...

The histological diagnosis in 77 cases of the nephrotic syndrome occurring in Uganda is presented. Plasmodium malariae was detected in 31 cases and all but one of these showed diffuse proliferative or focal glomerulonephritis. Pure membranous glomerulonephritis was seen in nine cases; none of these had parasitaemia. Children (63%) had a higher incidence of parasitaemia than adults (40%) in the ...

This Atomic Force Microscope image shows the surface of a Plasmodium malariae trophozoite-infected red blood cell isolated from a Burmese patient suffering from quartan malaria (top). Of note, the P. malariae-infected cell (bottom left) is covered with dense ‘spike-like’ excrescences (mean height: 7Æ59 nm; mean diameter: 52Æ95 nm), which are morphologically distinct from the larger, more rounde...
