L'étude a utilisé la technique de PCR-DGGE (électrophorèse sur gel de gradient dénaturant des produits de
réactions en chaîne de la polymérase), pour générer les profils génétiques des procaryotes dans des
échantillons de la colonne d’eau du lac Nyos. Par ailleurs, le clonage et le séquençage des gènes ARNr 16S
ont été effectués sur les(...)

Serotyping and antimicrobial susceptibility of Salmonella isolated from children under five years of age with diarrhea in rural Burkina Faso
René Dembélé, Ali Konaté, Isidore Juste O. Bonkoungou, Assèta Kagambèga, Kiessoun Konaté, T. Serge Bagré, Alfred S. Traoré, Nicolas Barro
Diarrheal infections are an important public health problem worldwide but there is limited information on the molecular characteristics of responsible agents in Burkina Faso, especially in the countryside. The objective of this study was to investigate the prevalence, serotypes and antibiotic susceptibility patterns of Salmonella enterica in d(...)

CK2 accumulation at the axon initial segment depends on sodium channel Nav1
Y.E. Hien, A. Montersino, F. Castets, C. Leterrier, O. Filhol, H. Vacher, B. Dargent
Accumulation of voltage-gated sodium channel Nav1 at the axon initial segment (AIS), results from a direct interaction with ankyrin G. This interaction is regulated in vitro by the protein kinase CK2, which is also highly enriched at the AIS. Here, using phosphospecific antibodies and inhibition/ depletion approaches, we showed that Nav1 chann(...)

Purification and Characterization of Sweet Potato (Ipomoea Batatas) Peroxidase.
Mamounata Diao, Brice N’cho Ayékoué, Crépin I. Dibala, Soumaïla Dabonné and Mamoudou H. Dicko
Peroxidase (POX), a biotechnologically important enzyme was purified from bulb of Ipomoea batatas and characterized for use in the bioconversion of phenolic compounds from industrial wastewater. Purified peroxidase (POXp) was obtained using the gel-filtration chromatography and anion exchange chromatography. A final yield of 18 % was obtained(...)

Isolation and Characterization of hydrocarbondegrading Bacteria from Wastewaters in Ouagadougou,Burkina Faso
Sawadogo Adama, Otoidobiga C.Hamonie, Sawadogo B. Joseph, Kaboré Aminata, Traoré S. Alfred, Dianou Dayéri
Lubricants are very often found in nature under waste-oil forms and represent for the environment a real danger of pollution due to the difficulty of their biodegradation. The situation is especially worrying in most developing countries in particular those of Sub-Saharan Africa due to the absence of regulation or control. The present work aim(...)

Studies in the Evaluation of Unconventional Oils from Burkina Faso Rich in Linoleic Acid, Oleic Acid or Other Unusual Fatty Acids
BAZONGO Patrice, Bassole IHN, Soren Nielsen, Mamoudou H. DICKO and Vijai KS Shukla
A study on unconventional seed oils from Burkina Faso was carried out to determine their potential usefulness. The highest oil content was obtained with Marantes polyandra (55.0%) and the lowest with Detarium microcarpum seed oil (12.0%). Linoleic and oleic acids were the most dominant fatty acids of Balanites aegyptiaca, Combretum aculeatum,(...)

Introduction
Due to the existence of a variety of types of non-venereal syphilis caused by the related T. pallidum, regular serological testing such as Rapid Plasma Reagin (RPR) and Chemiluminescent Microparticle Immunoassay Technique (CMIA) are often unable to differentiate venereal syphilis from the non- venereal one, hence, the interest in(...)

M. Kronborg, J.B. Ilboudo, I.H.N. Bassolé, A.S. Barfod, H.W. Ravn, and A.M. Lykke
Knowledge of the correlates of product quality is a prerequisite for further commercialization of soumbala, a food
product extracted from the leguminous tree Parkia biglobosa (Jacq.) G. Don. In this study qualitative and quanti-
tative data derived from interviews of producers and expert users are used to estimate the influence of P. biglo-(...)
