BACKGROUND Antibodies that protect against Plasmodium falciparum (Pf) malaria are only acquired after years of repeated infections. The B cell biology that underlies this observation is poorly understood. We previously reported that "atypical" memory B cells are increased in children and adults exposed to intense Pf transmission in Mali, similar to what has been observed in individuals infected...

BACKGROUND Maternal mortality is high in Mali. Nevertheless, there are few studies on this topic from rural areas, and current estimates are mostly based on studies from urban settings. Our objective was to estimate the maternal mortality ratio in Kita, rural Mali. METHODS Using the "sisterhood method", we interviewed participants aged 15-50 years from 20 villages in Kita, Mali, and thereby c...

seasonal activity and spatial distribution of eoteranychus frosti mcgregor, tydeus longisetosus (elbagouy and momen) and zetzellia mali ewing were studied during 9th july to 22th october 2006 in an unsprayed apple orchard, maragheh region, northwest of iran. also the density dependence interaction between preys and predator was assessed. to estimate the spatial distribution pattern of these spe...

Mali is located in the Sahel region of West Africa, to the south-west of Algeria and north of Burkina Faso and Niger (Figure 1). It has a large area of some 1.24 million square kilometres. The terrain is dominated by flat or rolling sand-capped plains in the north and savannah in the south, although rugged hills occur in the north-east. Elevation varies from the highest point at Hombori Tondo (...

OBJECTIVES Meningococcal meningitis (MM) is still a huge threat in the African meningitis belt. To fight against epidemics, a strengthened health information system, based upon weekly collected data, was set up in Mali. We aimed to study the spatio-temporal dynamics of MM in this country between 1992 and 2003. METHODS We were first interested in the impact of population size on the disease pe...

Previous studies have shown that there is a circadian rhythm of photosensitivity in different rodent species of the Sahel (Burkina Faso) and that, despite the low amplitude of seasonal variations in daylength, the photoperiod may control reproductive function. The present investigation of Arvicanthis niloticus provides additional support for this hypothesis. Populations of Arvicanthis niloticus...

sooty blotch and flyspeck occur on fruit surfaces and result in economic losses due to less attractive appearance. sooty blotch fungi form dark mycelial mats whereas flyspeck fungal agents are well characterized with black, sclerotium-like bodies on fruit surface. whilst more than 60 species have been reported in association with these two fungal diseases, thus far they have not been studied in...
