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(...)

Dynamics of the invasive Bemisia tabaci (Homoptera: Aleyrodidae) Mediterranean (MED) species in two West African countries
Bemisia tabaci Gennadius is a major pest on cotton and vegetable plants in Africa. It is considered as a cryptic species complex. Identification of the most damaging species such as the Middle East–Asia Minor 1 (B biotype) and Mediterranean (MED)(which contains the Q and Africa silverleaf (ASL) biotypes) species represents an important step to(...)

Detection of genetically isolated entities within the Mediterranean species of Bemisia tabaci: new insights into the systematics of this worldwide pest
BACKGROUND The taxonomy of the species complex Bemisia tabaci, a serious agricultural pest worldwide, is not well resolved yet, even though species delimitation is critical for designing effective control strategies. Based on a threshold of 3.5% mitochondrial (mtCOI) sequence divergence, recent studies have identified 28 putative species. Amon(...)

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(...)

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(...)

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(...)

Physicochemical Characteristics and Composition of Three Morphotypes of Cyperus esculentus Tubers and Tuber Oils
A. OUEDRAOGO
Tuber characteristics and nutrient composition of three morphotypes of Cyperus esculentus tubers and tuber oils were determined. The mean value for length and width of the tuber and one thousand dried tuber weights ranged from 0.98 to 1.31 cm, 0.90 to 1.19 cm, and 598 to 1044 g, respectively. Tubers displayed high level of starch (30.54–33.21(...)

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(...)

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(...)

Pulmonary embolism mimicking acute anterior myocardial infarction: diagnostic trap
N. YAMEOGO
Pulmonary embolism remains the major malingerer of acute chest disease. The clinical and electrocardiographic manifestations may deviate to a diagnosis of myocardial infarction. We report a case of bilateral pulmonary embolism in a patient of 50 years. The electrocardiogram showed ST elevation in anteroseptal and lateral leads. The diagnosis o(...)

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(...)

On the interest of ambipolar materials for gas sensing
Based on the electrochemical properties of a series of metallophthalocyanines this article shows that the phthalocyanine bearing four alkoxy groups and twelve fluorine atoms behaves approximately as those with eight fluorine atoms. This indicates that the electron-donating effect of one alkoxy group balances the electro-withdrawing effect of o(...)
