The prevalence and diversity of intestinal parasitic infections in humans and domestic animals in a rural Cambodian village (Publications)
In Cambodia, intestinal parasitic infections are prevalent in humans and particularly in children. Yet, information on potentially zoonotic parasites in animal reservoir hosts is lacking. In May 2012, [...] al studies will aid characterisation of parasite species and genotypes and allow further insight into the potential for zoonotic cross transmission of parasites in this community. [...] used to confirm hookworm, Ascaris spp., Giardia spp. and Blastocystis spp. Major gastrointestinal parasitic...
Transcriptional profiling defines dynamics of parasite tissue sequestration during malaria infection (Publications)
BACKGROUND: During intra-erythrocytic development, late asexually replicating Plasmodium falciparum parasites sequester from peripheral circulation. This facilitates chronic infection and is linked to severe [...] cells - likewise disappear from circulation. Recent work has demonstrated that these sexual stage parasites are located in the hematopoietic system of the bone marrow before mature gametocytes are released [...] functional modules (clusters) of genes that are co-expressed primarily...
Transcriptional profiling defines histone acetylation as a regulator of gene expression during human-to-mosquito transmission of the malaria parasite... (Publications)
Transmission of the malaria parasite Plasmodium falciparum from the human to the mosquito is mediated by the intraerythrocytic gametocytes, which, once taken up during a blood meal, become activated to [...] to initiate sexual reproduction. Because gametocytes are the only parasite stages able to establish an infection in the mosquito, they are crucial for spreading the tropical disease. During gametocyte [...] of P. falciparum, little is known about this process during human-to-mosquito...
Estimation of malaria parasite reservoir coverage using reactive case detection and active community fever screening from census data with rapid... (Publications)
conducted in southern Zambia to estimate the coverage of RCD or fDA in terms of the population and parasite reservoir as well as the operational requirements of such strategies, using a re-sampling algorithm [...] with search radii over several hundered meters will only yield limited coverage of the RDT positive parasite reservoir during a short period. Long-term use of these strategies may increase this proportion [...] radius. CONCLUSIONS: Reactive strategies in southern Zambia yield improved...
Antimalarial lead-optimization studies on a 2,6-imidazopyridine series within a constrained chemical space to circumvent atypical dose-response curves... (Publications)
resistant malaria parasite strains guided the optimization process to define a chemical space that led to typical sigmoidal dose-response and complete kill of multidrug resistant parasites. After a structure
Sex: how malaria parasites get turned on (Publications)
The mechanisms underlying sexual stage switching in Plasmodium spp. have hitherto remained a mystery. However, two recent studies have revealed that an apicomplexan-specific DNA-binding protein is ess

At a concentration [...] falciparum merozoites, and antibodies against PfCyRPA can efficiently prevent the entry of the malaria parasites into red blood cells. The aim of the present study was to develop a humancompatible formulation [...] concentration of 10 mg/mL, purified total serum IgG from...
Nutritional status and intestinal parasites among young children from pastoralist communities of the Ethiopian Somali region (Publications)
in the Ethiopian Somali Regional State (ESRS) are at high risk for undernutrition and intestinal parasitic infections (IPIs). We assessed the nutritional status and its association with IPIs in 500 children
