Involvement of class 1 and class 2 integrons in dissemination of tet and catA1 resistance genes of Salmonella enterica from children with diarrhea in rural Burkina Faso

With high annual mortality rates among young children, antimicrobial resistant salmonellosis is considered a major public health concern worldwide. Antimicrobial resistant salmonellosis is a worldwide health issue, particularly in low income countries with high microbially-derived food contaminations. As a result, it is important to better understand the biological factors that may control these bacteria’s...

Impact of transgenic conversion on the characteristics of Burkina Faso cotton

Genetically modified cotton (GMC) was compared with two conventional cultivars, using data from trials and commercial farms. Objectives were to highlight disparate agronomic and technological performance parameters and identify perspectives to Burkina Faso comeback to GMC. Results showed that compared materials are similar for most agronomic characteristics, except fiber percent. As this important parameter is...

Effect of two agro-pedo-climatic zones, drying methods and pelleting processes on chemical composition of Manihot esculenta (sp.), Leucaena leucocephala and Cajanus cajan

In tropical and subtropical countries, livestock productivity may be affected by the availability of food resources and the high prevalence of gastrointestinal pathogenic nematodes. The classical method of control using anthelmintic drugs is becoming decreasingly efficient because of a generalised resistance of the gastrointestinal nematodes suppress (GIN) to most of the drugs. In small farms, protein-rich biomasses...

Bacterial and vermi-remediation of soil contaminated with chlorpyrifos insecticide

This study aimed at investigating the effect of consortia of three types of indigenous bacteria (Corynebacterium sp., Sphingobacterium gobiense and Kocuria flava) and earthworm (at 5 and 10 earthworms/kg soil) and their combination on the percentage removal of chlorpyrifos from chlorpyrifos contaminated soil in Sudan. Silt soil (Gerf soil) samples were mixed with known concentration of chlorpyrifos (450 mgkg-1) and...

Studies on some major yield responsive genes in selected rice (Oryza species) cultivars grown in Nigeria using candidate gene SSR-based markers approach

This study was aimed at determining the presence of five major yield responsive genes shown to be among key determinants of rice yield in ten rice cultivars grown in Nigeria using candidate gene SSRs markers (Cg-SSRs). DNAs were extracted from young leaf samples using optimized cetyltrimethylammonium bromide (CTAB)-extraction method. An established gene sequences for high yielding rice Nipponbare cultivar for the five...

Amino acyl tRNA synthetase inhibitors is therapeutics for gliomas at sub nanomolar concentrations

Glioblastoma is the most malignant and fatal of all primary brain tumors. Each year in the United States, about 22,000 cases of glioma are diagnosed and about 70% of these patients die. The current treatment modality options available for glioma patients are limited to temozolomide, radiation, and surgery. The poor outcome with these treatment options has necessitated the search for a better chemotherapeutic strategy to...

Lack of association of toll-like receptor 2 rs3804100 polymorphism with paediatric tuberculosis in South Africa

Toll-like receptor 2 (TLR 2) genetic polymorphisms are important factors that are involved in the development of clinical tuberculosis. In this study, a single nucleotide polymorphism of the immune response protein molecule, toll-like receptor 2 designated as rs3804100 involving T/C polymorphism was carried out by genotypic analysis of DNA obtained from blood samples of the paediatric population in South Africa...

Antiproliferative effect of Amburana cearensis seed extracts on human cancer cell lines

Amburana cearensis A. C. Smith (Fabaceae) is a plant of Brazil, popularly known as umburana or cumaru, and is widely used in folk medicine. The population uses its bark and seeds against many pathologies including cancer. The aim of this study was to examine the antiproliferative effect of A. cearensis extracts on human tumor cell lines of HT-29 colon adenocarcinoma and HepG2 hepatocellular carcinoma, as well as on...
