Epidemiological and clinical aspects of urogenital schistosomiasis in women, in Burkina Faso, West Africa
BACKGROUND Because infections with Schistosoma Haematobium usually peak in childhood, the majority of studies on schistosomiasis have focused on school-aged children. This study aimed to assess the epidemiological and clinical aspects of urogenital schistosomiasis in women in Burkina Faso, West Africa. METHODS A cross-sectional study was conducted in a mesoendemic region (Kombissiri) and a hy...
متن کاملPopulation genetics of abnormal haemoglobins in Burkina Faso, west Africa.
The gene frequencies of haemoglobin A (HbA), HbS and HbC were studied in Burkina-Faso (BF) and in a neighbouring region of Niger, Ayorou. The frequency of HbS was higher in the Sahel region, (northern part of BF and Ayorou) than in the Savanna region. The reverse was true for the HbC gene. The major findings of this study are: (a) confirmation of a peak of HbC gene frequency in the central regi...
متن کاملComparative study of civic agency in Burkina Faso and Togo
Despite a long-standing controversy about aid-effectiveness in general and the impact of aiddependency on governance in particular, little is known on the effect of donors policies on civic agency for democratization in aid dependent autocratic regimes. In this study it is argued that the long-term effects of double-talk of donors, who openly promote democracy and freedom but covertly follow ov...
متن کاملDivergence with gene flow in Anopheles funestus from the Sudan Savanna of Burkina Faso, West Africa.
Anopheles funestus is a major vector of malaria across Africa. Understanding its complex and nonequilibrium population genetic structure is an important challenge that must be overcome before vector populations can be successfully perturbed for malaria control. Here we examine the role of chromosomal inversions in structuring genetic variation and facilitating divergence in Burkina Faso, West A...
متن کاملMultiple Insecticide Resistance in Anopheles gambiae s.l. Populations from Burkina Faso, West Africa
Malaria control programs are being jeopardized by the spread of insecticide resistance in mosquito vector populations. The situation in Burkina Faso is emblematic with Anopheles gambiae populations showing high levels of resistance to most available compounds. Although the frequency of insecticide target-site mutations including knockdown resistance (kdr) and insensitive acetylcholinesterase (A...
