Régénération sexuée de Boswellia dalzielii Hutch., un arbre médicinal de grande valeur au Burkina Faso

A. OUEDRAOGO

Résumé Boswellia dalzielii Hutch. est une plante principalement utilisée en pharmacopée traditionnelle. Elle compte parmi les espèces les plus menacées à l'est du Burkina Faso. L'espèce subit un écorçage intensif, qui la met en péril, et sa régénération est faible. Une collecte de fruits a été réalisée dans plusieurs peuplements pour étudier l(...)

Congenital malformations and medical conditions associated with orofacial clefts in children in Burkina Faso

K. NAGALO

Orofacial clefts are usually isolated cases but can be associated with other congenital malformations that are either recognised or unrecognised syndromes. The reported prevalence and pattern of such associated malformations, however, vary among studies. Objectives: To assess the frequencies and aetiologies of congenital malformations and asso(...)

Distribution of Bemisia tabaci (Homoptera: Aleyrodidae) biotypes and their associated symbiotic bacteria on host plants in West Africa

1. The whitefly Bemisia tabaci is a pest of many agricultural and ornamental crops worldwide and particularly in Africa. B. tabaci is a complex of more than 20 biotypes. Effective control of B. tabaci calls for a greater knowledge of the local biological diversity in terms of biotypes or putative species. Information is available about biotype(...)

Evaluation of the sensitivity of Aedes aegypti and Anopheles gambiae complex mosquitoes to two insect repellents: DEET and KBR 3023

A. BADOLO

We conducted laboratory tests to assess the sensitivity to the insect repellent 1‐piperidinecarboxylic acid, 2‐(2‐hydroxyethyl)‐, 1‐methylpropylester (known as KBR 3023 or Picaridin, trade name Bayrepel®) of West African strains of the yellow fever mosquito Aedes aegypti and of malaria vectors of the Anopheles gambiae complex, in comparison wi(...)

Infective endocarditis in sub-Saharan African children, cross-sectional study about 19 cases in Ouagadougou at Burkina Faso

N. YAMEOGO

INTRODUCTION: Infective endocarditis is a transplant of a microorganism on a most often injured endocardium. It is rare in children. This work aimed to determine the frequency of endocarditis of the child, to describe clinical presentation, data from echocardiography, microbiological profile and clinical course. PATIENTS AND METHODS: From May(...)

Association mapping by pooled sequencing identifies TOLL 11 as a protective factor against Plasmodium falciparum in Anopheles gambiae

A. GNEME

The genome-wide association study (GWAS) techniques that have been used for genetic mapping in other organisms have not been successfully applied to mosquitoes, which have genetic characteristics of high nucleotide diversity, low linkage disequilibrium, and complex population stratification that render population-based GWAS essentially unfeasi(...)

Utilisations, état des peuplements et régénération de cinq espèces ligneuses utilitaires dans l’est du Burkina Faso

A. OUEDRAOGO

La raréfaction des espèces à importance économique et les besoins croissants en produits végétaux constituent de nos jours des facteurs d'aggravation de la pression sur les espèces utilitaires. L'exploitation abusive est la cause majeure de la destruction de nombreuses espèces végétales (Ozenda 1982). Dans les conditions climatiques précaires(...)

Association between sickle cell trait and low density parasitaemia in a P. falciparum malaria holoendemic region of Western Kenya

A. BADOLO

Aims: The frequency of the mutant gene for sickle cell is widely distributed in the sub-Saharan Africa, the Middle East, and the Indian subcontinent. There is epidemiologic evidence that sickle cell trait confers a survival advantage against malaria and that the selection pressure due to malaria has resulted in high frequencies of the mutant g(...)

The influence of termite-induced heterogeneity on savanna vegetation along a climatic gradient in West Africa

A. THIOMBIANO

Termites are renowned ecosystem engineers. Their mounds have been described as an important element of savanna vegetation dynamics, but little is known about their large-scale impact on vegetation composition. To investigate the influence of termite-induced heterogeneity in savannas along a climatic gradient in West Africa termite mound vegeta(...)

Plasmodium species occurrence, temporal distribution and interaction in a child-aged population in rural Burkina Faso

A. GNEME

Malaria can be caused by five Plasmodium species. Due to their higher prevalence, much of the research concentrates on Plasmodium falciparum and Plasmodium vivax. In Burkina Faso, where P. falciparum co-exists with Plasmodium malariae and Plasmodium ovale, there is not much data about the prevalence of the latter two species across human popul(...)
