Plasmodium Calcium Dependent Protein Kinase (CDPK1) is required for the development of sexual stages in the mosquito. In addition, it is proposed to play an essential role in the parasite's invasive stages possibly through the regulation of the actinomyosin motor and micronemal secretion. We demonstrate that Plasmodium berghei CDPK1 is dispensable in the parasite's erythrocytic and pre-erythroc...

This study was conducted to determine the effects of Ficus exasparata (sand paper plant) on albino mice experimentally infected with Plasmodium berghei berghei. The were grouped into four five each. in groups A,B, and C inoculated while those group D not parasite serve as control group. Group A B treated ethanoic leaf extract 100mg/body weight/day 200mg/body respectively for six days after inoc...

Transmission-blocking interventions aim to reduce the prevalence of infection in endemic communities by targeting Plasmodium within the insect host. Although many studies have reported the successful reduction of infection in the mosquito vector, direct evidence that there is an onward reduction in infection in the vertebrate host is lacking. Here we report the first experiments using a populat...

Plasmodium berghei yoelii infection in mice severely depressed the splenic antibody response to sheep erythrocytes but had lettle effect on antibody formation in lymph nodes.

Background & Aim: Antiplasmodial activity of leaf extract of Breynia nivosa was evaluated to ascertain the folkloric claim of its antimalarial activity. Experimental: The crude leaf extract (75 – 225 mg/kg), of Breynia nivosa was investigated for antiplasmodial activity against chloroquine sensitive Plasmodium berghei infections in mice. The antiplasmodial activity d...

In a recent study, SM1-transgenic Anopheles stephensi, which are resistant partially to Plasmodium berghei, had higher fitness than non-transgenic mosquitoes when they were maintained on Plasmodium-infected blood. This result should be interpreted cautiously with respect to malaria control using transgenic mosquitoes because, despite the evolutionary advantage conferred by the transgene, a conc...

Glutathione plays a central role in maintaining cellular redox homeostasis, and modulations to this status may affect malaria parasite sensitivity to certain types of antimalarials. In this study, we demonstrate that inhibition of glutathione biosynthesis in the Plasmodium berghei ANKA strain through disruption of the γ-glutamylcysteine synthetase (γ-GCS) gene, which encodes the first and rate-...

Artemisinin and curcumin show an additive interaction in killing Plasmodium falciparum in culture. In vivo, 3 oral doses of curcumin following a single injection of alpha,beta-arteether to Plasmodium berghei-infected mice are able to prevent recrudescence due to alpha,beta-arteether monotherapy and ensure almost 100% survival of the animals.

BACKGROUND Plasmodium parasites need to cross the midgut and salivary gland epithelia to complete their life cycle in the mosquito. However, our understanding of the molecular mechanism and the mosquito genes that participate in this process is still very limited. METHODOLOGY/PRINCIPAL FINDINGS We identified an Anopheles gambiae epithelial serine protease (AgESP) that is constitutively expres...

Quantitative reverse transcription PCR (qRT-PCR) has been an integral part of characterizing the immunity of Anopheles mosquitoes towards Plasmodium invasion. Two anti-Plasmodium factors of Anopheles, thioester-containing protein 1 (TEP1) and nitric oxide synthase (NOS), play a role in the refractoriness of Anopheles towards Plasmodium infection and are generally expressed during infection. How...
