Cowpea [Vigna unguiculata (L.) Walp.] is a legume whose immature pods are consumed
and marketed. However, it suffers yield losses due to attacks of aphid-transmitted mosaic
disease. The present work is a study of the genetic resistance of twelve (12) varieties of
vegetable cowpea to Cowpea Aphid-Borne Mosaic Virus (CABMV) at Kamboinsé. The(...)

ACUTE AND SUBACUTE TOXICITIES OF THE AQUEOUS EXTRACT OF THE LEAVES OF CELOSIA TRIGYNA (L.)
Sawadogo Touwindséda Aimée, Ouédraogo Youssoufou, Da Filkpièrè Léonard, Ilboudo Sylvain, Sawadogo Paténéma and Bayala Balé
Celosia trigyna (C. trigyna) is a plant which is widely used in Burkina Faso as traditional medicine and human food. The aim of this study is to screen the phytochemical component of the extract and evaluate the safe of C. trigyna by acute and subacute toxicity with Wistar rat. During four weeks daily administration, subacute toxicity was inve(...)

Vasorelaxant effects of Psidium guajava L. (Myrtaceae) aqueous leaf extract on rat aorta
Ouedraogo Youssoufou, Sawadogo Paténéma, Tougouma Larba Colette, Sawadogo Touwindséda Aimée, Da Filkpièrè Léonard, Bayala Balé and Belemtougri G Raymond
Psidium guajava is widely used in the central plateau of Burkina Faso to treat many diseases among which hypertension. Aqueous leaf extract of this plant was evaluated on wistar rat aorta precontracted by Norepinephrine (NE) or 5-hydroxytrytamine (5-HT). The results showed endothelium-independent vasodilation. The plant extract relaxed NE and(...)

Extended spectrum beta-lactamase and fluoroquinolone resistance genes among Escherichia coli and Salmonella isolates from children with diarrhea, Burkina Faso.
René Dembélé, Ali Konaté, Oumar Traoré, Wendpoulomdé A. D. Kaboré, Issiaka Soulama, Assèta Kagambèga, Alfred S. Traoré, Nathalie K. Guessennd, Awa Aidara- Kane, Amy Gassama-Sow and Nicolas Barro
Background: The emergence and spread of multidrug-resistant gram-negative bacteria (MDR) has become a major
public health concern worldwide. This resistance is caused by enzymes-mediated genes (i.e., extended spectrum
beta-lactamases) that are common in certain Enterobacterioceae species. However, the distribution of these genes is
poorly d(...)

Long‐term changes in population size and the age structure and sex ratio of waterbuck in a Sudanian savannah of Burkina Faso
Sidiki Konate, Djidama Sirima, Lankoande Ardjima, Youssouf Sanou, Emmanuel M. Hema, B. Gustave Kabre, Julia E. Fa, Luca Luiselli, Fabio Petrozzi
Abstract The waterbuck (Kobus ellipsiprymnus), though widespread throughout Africa, is suspected to be declining overall. Data on population numbers and structure are lacking for many parts of its range, especially in West Africa, where the subspeciesdefassais found. The aim of the present study was to evaluate the abundance, distribution and(...)

The seasonal distribution of savannah elephants (Loxodonta africana africana) in Nazinga Game Ranch, southern Burkina Faso
Emmanuel M. Hema, R. F. W. Barnes, Wendengoudi Guenda
Elephant wet and dry season distributions were compared at Nazinga Game Ranch in southern Burkina Faso. Dropping counts along line transects provided an index of occupancy at the end of each season: wet 2006, dry 2007 and dry 2008. We expected that the distribution of elephants would differ between the dry and the wet seasons, with elephants c(...)

Age-stratified interview campaigns suggest ongoing decline of a threatened tortoise species in the West African Sahel
Luca Luiselli, Godfrey C. Akani, Edem A. Eniang, Massimiliano Di Vittorio, Fabio Petrozzi, Emmanuel M. Hema, Gabriel Hoinsoudé Segniagbeto, Daniele Dendi, Tomas Diagne, Laurent Chirio, Julia E. Fa
Face-to-face interviews with local populations are often used to determine the distribution and population trends of elusive threatened species. Although interviewee responses may suffer from some bias, historical trends in the status of a species can be investigated from age-structured questionnaires. In this paper, we tested this idea by ana(...)

The redistribution of thorium, uranium, potassium by magmatic and hydrothermal processes versus surface processes in the Saraya Batholith (Eastern Senegal): Insights from airborne radiometrics data and topographic roughness
Makhoudia Fall, David Baratoux, Mark Jessell, Papa Moussa Ndiaye, Oliver Vanderhaeghe, Jean François Moyen, Lenka Baratoux, Wilédio Marc-Emile Bonzi
Potassium (K), thorium (Th), and uranium (U) are incompatible elements, with various degrees of mobility with respect to hydrothermal alteration or weathering and are taken as tracers for magmatic, fluid-rock interactions and mineralization. These elements may be mapped from airborne radiometric surveys revealing their spatial distribution at(...)

Hydrogeochemical and pollution characterization of a shallow glauconitic sandstone aquifer in a peri‑urban setting of Bobo‑Dioulasso, southwestern Burkina Faso
Aboubakar Sako, Sâga Sawadogo, Mamadou Nimi and Mahamadou Ouédraogo
Groundwater resources are often exposed to multiple sources of pollution, which may make them unfit for human consumption. As a result, comprehensive geochemical studies on groundwater status and evolution are required for a sustainable management of water resources. In the present study, 38 water samples from hand-dug wells were collected in(...)

Line-transect data may not produce reliable estimates of interannual sex-ratio and age structure variation in West African savannah ungulates
Emmanuel M. Hema, Yaya Ouattara, Maomarco Abdoul Ismael Tou, Giovanni Amori, Mamadou Karama, Luca Luiselli
Adult sex ratios and age structures are important wildlife population parameters, but they have been poorly investigated in ungulate species in West African savannahs. We used line transects to investigate these parameters in 11 ungulates from a protected area in south-western Burkina Faso during the period 2010-2018. We created an empirical m(...)
