Multi-country evaluation of the durability of pyrethroid plus piperonyl-butoxide insecticide-treated nets: study protocol (Publications)
distributions of long-lasting insecticidal nets (LLINs) have contributed to large reductions in the malaria burden. However, this success is in jeopardy due in part to the increasing pyrethroid-resistant mosquito [...] containing pyrethroid and piperonyl-butoxide (PBO) have shown a greater reduction in the incidence of malaria than pyrethroid LLINs in areas with pyrethroid-resistant mosquitoes. However, the durability (attrition
Expansion of artemisinin partial resistance mutations and lack of histidine rich protein-2 and -3 deletions in <em>Plasmodium falciparum</em>... (Publications)
BACKGROUND: Emerging artemisinin partial resistance and diagnostic resistance are a threat to malaria control in Africa. Plasmodium falciparum kelch13 (k13) propeller-domain mutations that confer artemisinin [...] provide early detection of partner drug resistance, which would likely compromise control and increase malaria morbidity and mortality in East Africa.
Co-infection of the four major <em>Plasmodium </em>species: effects on densities and gametocyte carriage (Publications)
BACKGROUND: Co-infection of the four major species of human malaria parasite Plasmodium falciparum (Pf), P. vivax (Pv), P. malariae (Pm), and P. ovale sp. (Po) is regularly observed, but there is limited [...] (95% CI: 0.95, 1.79) for gametocytes. This excess co-infection risk was partially attributable to malaria infections clustering in some villages. Pf-Pv-Pm triple infections were four times more frequent
Sub-lethal exposure to chlorfenapyr reduces the probability of developing <em>Plasmodium falciparum</em> parasites in surviving Anopheles mosquitoes (Publications)
BACKGROUND: Pyrethroid resistance in the key malaria vectors threatens the success of pyrethroid-treated nets. To overcome pyrethroid resistance, Interceptor(®) G2 (IG2), a 'first-in-class' dual insecticidal [...] the intensity of the P. falciparum infection. This will likely also contribute to the reduction of malaria in communities beyond the direct killing of mosquitoes.
Adherence to standard treatment guidelines among prescribers in primary healthcare facilities in the Dodoma region of Tanzania (Publications)
in 2872 cases. The nine most prevalent conditions were upper respiratory tract infections (25%), malaria (18%), diarrhoea (9.9%), pneumonia (6.1%), skin problems (5.8%), gastrointestinal diagnoses (5%) [...] of cases that did not adhere to STG was highest with patients with skin problems and lowest for malaria. Conclusion: Prescribers' general adherence to national STG in primary HCF in the public sector in
Peri-domestic vector control interventions using attractive targeted sugar baits and push-pull strategies (Publications)
Great challenges to sustained malaria and arbovirus control remain, including transmission by vectors that occur outdoors or outside of sleeping hours, the enormous scale of larval breeding in urban centres [...] finding could potentially be due to the size of these studies, because community-level protection from malaria using removal trapping has been demonstrated.
Evaluation of ethnobotanically selected Benin medicinal plants for their in vitro antiplasmodial activity (Publications)
Twenty extracts from nine Benin medicinal plants, traditionally used to treat malaria, were screened for in vitro antiplasmodial activity towards Plasmodium falciparum K1 chloroquine resistant and 3D7
Imidazolopiperazines: lead optimization of the second-generation antimalarial agents (Publications)
mice. The optimized compounds were found to be more efficacious than the current antimalarials in a malaria mouse model. They exhibit moderate oral exposure in rat pharmacokinetic studies to achieve sufficient
The pharmacokinetics and drug-drug interactions of ivermectin in <em>Aedes aegypti</em> mosquitoes (Publications)
Mosquitoes are vectors of major diseases such as dengue fever and malaria. Mass drug administration of endectocides to humans and livestock is a promising complementary approach to current insecticide-based
Phytochemical study and antiprotozoal activity of compounds isolated from <em>Thalia geniculata</em> (Publications)
Thalia geniculata L. (Marantaceae) is an African medicinal plant traditionally used in Benin to treat malaria and other parasitic diseases. There is little ethnobotanical and almost no chemical information available
