Evidence of diversity and recombination in Arsenophonus symbionts of the Bemisia tabaci species complex
Maternally inherited bacterial symbionts infecting arthropods have major implications on host ecology and evolution. Among them, the genus Arsenophonus is particularly characterized by a large host spectrum and a wide range of symbiotic relationships (from mutualism to parasitism), making it a good model to study the evolution of host-symbiont(...)

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(...)

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(...)

Risques liés à l’utilisation d’insecticides au cours du stockage du niébé (Vigna unguiculata L. Walp.) dans la région centrale du Burkina Faso
ABSTRACT L'utilisation des insecticides par les acteurs de la chaine des valeurs du niébé met à jour la problématique des risques supposés ou réels de ces produits vis-à-vis de l'homme et de son environnement. Pour évaluer les risques sanitaires et environnementaux générés par ces insecticides nous avons mené des enquêtes auprès de 100 product(...)

Contribution à l'évaluation des potentialités d'Encarsia sp.(Hymenoptera: Aphelinidae) comme agent de lutte biologique contre la mouche blanche du cotonnier, Be...
Encarsia sp. is the main solitary endoparasitoid developing on the larvae of the cotton whitefly Bemisia tabaci (Gennadius), in western Burkina Faso. The biological control potential of this parasitoid is currently under investigation. Studies of some population parameters and biological control assays have been undertaken in the laboratory an(...)

Regulation of the Na+‐K+(NH)‐2Cl− cotransporter of rat submandibular glands
E. KABRE
A cellular suspension from rat submandibular glands was exposed to different concentrations of NH4Cl, and the variations of the intracellular concentration of calcium ([Ca2+] i) and the intracellular pH (pHi) were measured using fura‐2 and 2′, 7′‐bis‐(2‐carboxy‐ethyl)‐5 (6)‐carboxyfluorescein. More than 5 mmol/l NH4Cl significantly increased t(...)

Abundance of Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) and its parasitoids on vegetables and cassava plants in Burkina Faso (West Africa)
The whitefly Bemisia tabaci is a pest of many agricultural and ornamental crops worldwide and particularly in Africa. It is a complex of cryptic species, which is extremely polyphagous with hundreds of host plants identified around the world. Previous surveys in western Africa indicated the presence of two biotypes of the invasive MED species(...)

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(...)

Differences in hypertension between informal and formal areas of Ouagadougou, a sub-Saharan African city
B. SOURA
Countries of sub-Saharan Africa are increasingly confronted with hypertension and urbanization is considered to favor its emergence. This study aims to assess the difference in the prevalence of hypertension between formal and informal urban areas of Ouagadougou and to determine the risk factors associated with hypertension in these urban popu(...)

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(...)

Drying of “Amelie” mango (Mangifera Indica L.): Influence of temperature on drying rates and shrinkage curves from 50 to 90 C.
D. BATHIEBO
In this study, drying rates and shrinkage curves of Amelie mango are established from 50 to 90 C and the temperature influence is investigated. Results show that drying rates are greatly influenced by drying air temperature and most of the drying process takes place during the falling drying rate period. From 50 to 90 C, drying kinetics are su(...)

The kdr-bearing haplotype and susceptibility to Plasmodium falciparum in Anopheles gambiae: genetic correlation and functional testing
A. GNEME
Members of the Anopheles gambiae species complex are primary vectors of human malaria in Africa. It is known that a large haplotype shared between An. gambiae and Anopheles coluzzii by introgression carries point mutations of the voltage-gated sodium channel gene para, including the L1014F kdr mutation associated with insensitivity to pyrethro(...)

Evolution of GOUNDRY, a cryptic subgroup of Anopheles gambiae s.l., and its impact on susceptibility to Plasmodium infection
A. GNEME
The recent discovery of a previously unknown genetic subgroup of Anopheles gambiae sensu lato underscores our incomplete understanding of complexities of vector population demographics in Anopheles. This subgroup, named GOUNDRY, does not rest indoors as adults and is highly susceptible to Plasmodium infection in the laboratory. Initial descrip(...)

Huge right atrial myxoma revealed by right heart failure
N. YAMEOGO
Right atrial myxoma is a heart benignant tumor characterized by an important clinical polymorphism. We report a case of a 30-year-old female with a diagnosis of a big right atrial myxoma. The diagnosis has been done by transthoracic echocardiography which showed an important tumorous mass in the right atrium. It was moving, inhomogeneous and t(...)
