Malaria parasite densities also varied [...] to determine the impact of urbanization on the malaria infection (parasite) rate and parasite density, and their consequences on the heterogeneity of malaria transmission in urban Abidjan. Specifically we [...] tly between them. These results confirm the involvement of...
A prospective study of <em>Plasmodium falciparum</em> multiplicity of infection and morbidity in Tanzanian children (Publications)
individuals with substantial previous exposure to malaria, co-infection with multiple clones of Plasmodium falciparum can protect against subsequent clinical malaria attacks. Other studies, mainly of individuals [...] These results provide further evidence that relationships between asymptomatic malaria infections and clinical malaria change with cumulative exposure. [...] multiplicity of infection increased with age. In the first year of life, the incidence of clinical malaria was almost three...
Rapid spread of double East- and West-African <em>kdr </em>mutations in wild <em>Anopheles coluzzi</em> from Côte d'Ivoire (Publications)
decrease of malaria burden. These tools are now threatened by insecticide resistance in malaria vectors, which is spreading dramatically. After two different real-time polymerase chain reaction molecular char [...] resistance in malaria vectors and highlight the urgent need to diversify the methods of vector control in order to avoid the failure of insecticide-based vector control tools which may favor malaria fatalities [...] Malaria morbidity and mortality rates in Sub-Saharan Africa are...
Absence of dry season <em>Plasmodium</em> parasitaemia, but high rates of reported acute respiratory infection and diarrhoea in presschool-aged... (Publications)
epidemiology of malaria in the Senegal River Gorgol valley, southern Mauritania, requires particular attention in the face of ongoing and predicted environmental and climate changes. While "malaria cases" are [...] ons in neighbouring regions point to an absence of malaria transmission in mosquito vectors in the dry season. Because the clinical signs of malaria are non-specific and overlap with those of other diseases [...] diseases (e.g. acute respiratory infections and diarrhoea), new research...
Status febrilis mit Bewusstlosigkeit (Publications)
Cerebral malaria with Plasmodium vivax is uncommon. Normally Plasmodium falciparum is the cause of cerebral malaria. We report about a 18 year old patient from Pakistan with a history of intermittent fever [...] several months. The patient recovered within a few days; however prognosis can be severe when cerebral malaria is complicating the course of Plasmodium vivax infection
Identifying risk factors for <em>Plasmodium </em>infection and anaemia in Kinshasa, Democratic Republic of Congo (Publications)
risk factors for malaria infection in large cities in central Africa and in all age groups. There may be different associations with the risk factors for areas with different malaria transmission intensities [...] (non-rural), collected during a cross sectional malaria survey in 2011. Logistic regression with random effects was used to investigate predictors for malaria and anaemia. Differences in risk factors in areas [...] whereas it increased with malaria infection and reported fever. ITN use...
Global diversity and balancing selection of 23 leading <em>Plasmodium falciparum </em>candidate vaccine antigens (Publications)
leading vaccine candidate antigens of P. falciparum using the MalariaGEN Pf3K (version 5.1) resource, comprising more than 2600 genomes from 15 malaria endemic countries. A stringent variant calling pipeline [...] genes encoding 23 leading and novel candidate malaria vaccine antigens including csp, trap, eba175, ama1, rh5, and CelTOS. Our analysis shows that current malaria vaccine formulations are based on rare haplotypes [...] Investigation of the diversity of malaria parasite antigens can...
Indigenous <em>Plasmodium malariae</em> infection in an endemic population at the Thai-Myanmar border (Publications)
Plasmodium malariae is a neglected malaria parasite. It has wide geographic distribution and, although often associated with mild malaria, is linked to a high burden of anemia and nephrotic syndromes. [...] participants, two were found to be infected with P. malariae. One had an infection that led to acute malaria, but the other was positive for P. malariae at multiple visits during the study and apparently had [...] explain how P. malariae has been able to thrive at very low prevalence and...
Naturally acquired immunoglobulin (Ig)G subclass antibodies to crude asexual <em>Plasmodium falciparum</em> lysates: evidence for association with... (Publications)
subclass antibody activity present before the beginning of a malaria transmission season (preseason antibody levels) against severe malaria has not been tested in longitudinal studies. We measured IgG [...] significantly different between the children who developed severe malaria and those who remained healthy during an observation period of two malaria transmission seasons. However, elevated levels of IgG1 in relation [...] protection from severe malaria (P = 0.02). Conversely, elevated levels...
Vaccine potentials of an intrinsically unstructured fragment derived from the blood stage-associated <em>Plasmodium falciparum</em> protein PFF0165c (Publications)
with its low polymorphism and association with clinical protection from malaria in humans, warrant its further development as a malaria vaccine candidate [...] We have identified new malaria vaccine candidates through the combination of bioinformatics prediction of stable protein domains in the Plasmodium falciparum genome, chemical synthesis of polypeptides [...] assays, and association of an antigen-specific antibody response with protection against clinical malaria.
