Resistance to antibiotics most especially third generation cephalosporins has assumed a worrisome dimension globally. Genes conferring these resistance which are mediated by enzymes known as extended spectrum beta-lactamases (ESBLs) now wide spread among several Enterobacteriaceae species. However there is paucity of data regarding the distribution genes in Burkina Faso. Hence this prospective study aims determine prevalence and ESBL encoding producing strains isolated from clinical samples...

The diversity of a highly variable RNA plant virus was considered to determine the range virulence substitutions, evolutionary pathways virulence, and whether intraspecific modulates propensity. In all, 114 isolates representative genetic geographic Rice yellow mottle (RYMV) in Africa were inoculated several cultivars with eIF(iso)4G-mediated Rymv1-2 resistance. Altogether, 41 virulent variants generated from ten wild analyzed. Nonconservative amino acid replacements at five positions...

Antimicrobial resistance (AMR) is a global public health threat. Quality data are needed to address the rise of multidrug-resistant clones, particularly in sub-Saharan Africa. In this study, we analysed prevalence, antimicrobial profile, and presence genes encoding extended-spectrum β-lactamase-producing Escherichia coli (ESBL-Ec) Klebsiella pneumoniae (ESBL-Kp) environmental samples from Ouagadougou, Burkina Faso. Of 264 collected, 95 (36%) 74 (28%) contained ESBL-Kp ESBL-Ec, respectively....

Vibrio cholerae is a human pathogen and natural inhabitant of aquatic environments. In this study, we surveyed the occurrence V. in fish harvested from reservoir that receives discharges population Ouagadougou through several channels.A total 238 80 water samples were analyzed for presence cholerae.Altogether, 13 strains isolated. They all identified as non-O1/non-O139 without ctxA gene. The mostly susceptible to antimicrobials tested.Although no epidemic serotypes encountered, it important...

This study presents an innovative analysis of the complex interplay between narcoterrorism and fanatical insurgency in Sahel region Africa. adopts a compartmental mathematical modeling approach to understand how these two phenomena influence each other they evolve. By making some data estimations simulations, we explore possible scenarios for evolution this difficult situation. The results our model provide essential information policy-makers security analysts. They allow us better...

Vegetable production in urban gardens of Ouagadougou contributes to food security, but water for irrigation is often low quality. This particularly acute if taken from wastewater polluted channels. study aimed at (i) verifying what degree quality correlated with contamination lettuce Escherichia coli, total coliforms, and Salmonella spp., (ii) assessing effects post-harvest handling on pathogen development during the trade chain. We tested removal efficiency by applying washing. Irrigation...

Abstract 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 these poorly documented Burkina Faso. study aims to determine prevalence resistant coding for broad beta-lactamases quinolones rural Methods Multiplex PCR assays were...

The presence of diarrheagenic Escherichia coli (DEC) in drinking water, is a grave public health problem. This study was aimed at characterization isolated from water and faecal samples diarrheic patients Ouagadougou, Burkina Faso.A total 242 consisting 182 potable sachets 60 boreholes were collected the period between October 2018 April 2019 city Ouagadougou. Faecal also 201 visiting National Public Health Laboratory for biological diagnosis by coproculture. virulence genes associated with...

Objectif: l’objectif de l’étude est contribuer au diagnostic du dessèchement manguier Burkina Faso. Il s’agit d’une part d’évaluer l’incidence et la sévérité maladie sur cinq variétés commerciales provenant Nahouri, Sissili, Houet, Comoé, Kénédougou Léraba d’autre d’inventorier les espèces champignons associées aux symptômes maladie.Méthodologie résultats: Une échelle 1 à 5 a été utilisée pour l’évaluation desséchement dans six provinces Sa prévalence évaluée pays. Les taux d’infections des...

Background and objective: In recent years, carbapenemase-producing Enterobacterales (CPE) resistance to antibiotics has dramatically increased leading limitations of their treatment options. the present study, we investigated occurrence Escherichia coli Salmonella in rural Burkina Faso.Materials methods: isolates were serotyped according Kauffman White scheme. Diarrheagenic (DEC) strains was identified using 16-plex Polymerase Chain Reaction (PCR), whereas antibiotic susceptibility realized...

The bollworm Helicoverpa armigera is cotton plant main pest in most parts of the world. mechanisms resistance to pyrethroid deltamethrin were studied by comparing field strains reference and susceptible strain (BK77). Resistance was using bio-assays. Results showed that collected had susceptibility 11 43 fold lower than standard BK77. Activities two types enzymes i.e., oxidases Glutathione-S-Transferases (GST) significantly higher strains, whereas esterase activities compared strain....

The CABRI facility is an experimental nuclear reactor of the French Atomic Energy Commission (CEA) designed to study behaviour fuel rods at high burnup under Reactivity Intitiated Accident (R.I.A.) conditions such as scenario a control rod ejection. During phase, element generates acoustic waves which can be detected by two microphones placed upstream and downstream from test device. Studies carried out on last fourteen tests showed interest in carrying temporal spectral analyses these...

In this paper we study a linear population dynamics model. model, the birth process is described by nonlocal term and initial distribution unknown. The aim of to use controllability result adjoint system for computation density individuals at some time T.

A strongly energetic spectral component has been observed in the operating noise of a research reactor before beginning reactivity-initiated accidents (RIAs). We identify source this by means analytical derivations torsional wave propagation test device. Numerical simulations, performed with spectral-element method, confirm that is resonant frequency device, and allow to evaluate impact travelpath device on acoustic emission (AE) signals recorded during RIA experiments. The transfer function...

Introduction: Enterobacteria are among the most frequent isolated strains in hospitalized patients. Currently, carbapenems have a broad spectrum of activity and considered to be last resort for treatment nosocomial infections. However, overuse these valuable compounds has led rapid increase antimicrobial resistance. The aim was study genetic kinetic profiles IMP NDM bacterial resistance enzymes Gram-negative pathogenic bacilli.
 Methodology: used strain susceptibility testing consisted...

This work explores some aspects of modeling and controlling narcoterrorism in the Sahel. We examine multidimensional factors underlying this dynamic, identifying interactions recruitment within narcoterrorist class. then develop a preventive model decision-support tools to optimize resource allocation formulate more effective counter-narcotics brigandage policies. research will certainly contribute fight against Sahel by proposing solutions based on rigorous scientific approaches assessing...

Terrorist activity in the Sahel region has been on increase for almost a decade. Groups advocating extremist ideologies with political or religious base are carrying out attacks against states aim of imposing totalitarian ideology, sometimes backdrop crisis and famine. In this state communal conflict, it is questionable whether ideological terrorism can really be eradicated Sahel. study, we develop model dynamics based situation particular, incorporates popular resistance to through class...
