Aim The objective of this study was to determine a formula for estimating the liveweight in West African donkeys. Materials and Methods Liveweight and a total of 6 body measurements were carried out on 1352 donkeys from Burkina Faso, Mali, Niger, and Senegal. The correlations between liveweight and body measurements were determined, and the most correlated body measurements with liveweight we...

This paper reports on some sea cucumbers (Holothuroidea) in the collections of the NHMUK, taken off the coast of Ghana. Most result from collections around Accra during the years 1949-52. A couple of other species are included. Altogether six species are here reported, viz. Holothuria (Holothuria) dakarensis Panning, 1939; Holothuria (Semperothuria) imitans Ludwig, 1875; Holothuria (Vaneyothuri...

The aim of this study was to provide standards for the assessment of birthweight, head circumference and crown-heel length for normal, singleton newborns of predominantly West African descent. Data were collected for 10 482 or 94% of all recorded births in Jamaica during the two-month period September 1 to October 31, 1986. After editing procedures, data were available for 6178 (birthweight), 5...

These proceedings summarize the results of research on dwarf sheep and goat production in humid West Africa. Among the topics discussed are disease profiles of village sheep and goats; feed intake, growth and reproduction rates of West African Dwarf goats; integration of the small ruminant enterprise into the wider farming system of the zone; and the economics of the improved production systems...

The primary Afrotropical malaria mosquito vector Anopheles gambiae sensu stricto has a complex population structure. In west Africa, this species is split into two molecular forms and displays local and regional variation in chromosomal arrangements and behaviors. To investigate patterns of macrogeographic population substructure, 25 An. gambiae samples from 12 African countries were genotyped ...

Since the 1988 World Health Assembly resolution to eradicate poliomyelitis, three World Health Organization (WHO) regions (Americas, European, and Western Pacific) have been certified polio-free, and the number of countries with endemic polio has decreased from 125 in 1988 to six in 2003 (Afghanistan, Egypt, India, Niger, Nigeria, and Pakistan). During January 2003-March 2004, importations of w...

Many indigenous West African plants have been employed as local remedies for various human ailments in the traditional medicine of the region, and as nutritional sources for countless generations [1-3]. Isolation and characterization of the chemical structures for phytochemicals from useful indigenous plants have however been undertaken only for a minimal fraction, largely because the modern te...

BACKGROUND The West African Health Organization (WAHO) implemented a research development program in West Africa during 2009-2013 using the Knowledge for Better Health Research Capacity Development Framework, developed by Pang et al. (Bull World Health Organ 81(11):815-820, 2003), on strategies used to improve the research environment. The framework has the following components: stewardship, fi...

[1] A suite of satellite data are used to study the near surface westerly winds developing during peak months (July–September) of the West African monsoon in the Atlantic Intertropical Convergence Zone. These new data show that the westerlies appear in the form of a westerly jet. During peak years the daily near-surface westerly wind speed may exceed 10 ms . The amplitude of the jet displays su...
