Twenty two distinct bacteriophages were isolated from sewage water five locations in the city of Abidjan, Côte d'Ivoire over a two-year period, using collection Pseudomonas aeruginosa strains with diverse genotypes. The phages characterized by their virulence spectrum on panel selected P. cystic fibrosis patients and whole genome sequencing. Twelve virions representing observed diversity visualised electron microscopy. combined observations showed that 17 phages, distributed into seven...

Among non-invasive biological samples, feces offer an important source of DNA and can easily be collected. However, working with fecal from highly vegetarians species such as elephant is more challenging because plant secondary compounds have inhibitory effect on PCR reactions. Working forest dung we tested adapted a protocol extraction developed plants based the Cetyltrimethylammonium bromide (CTAB) protocol. The relatively simple yields high concentration. It five-time less expensive...

Abstract Crop wild relatives (CWRs) have barely been used in eggplant ( Solanum melongena ) breeding. However, introgression breeding may help coping with the challenges posed by climate change. During rainy and dry seasons, we evaluated nine accessions of eggplant, seven related species (of which six are CWRs one is a cultivated relative), 12 interspecific hybrids. Drought tolerance scores, calculated as ratios growing rates mean values during were obtained for vegetative growth...

The development and promotion of biofortified foods plants are a sustainable strategy for supplying essential micronutrients human health nutrition. We set out to identify quantitative trait loci (QTL) associated with carotenoid content in cowpea sprouts. contents carotenoids, including lutein, zeaxanthin, β-carotene sprouts 125 accessions were quantified via high-performance liquid chromatography. Significant variation existed the profiles different carotenoids. Lutein was most abundant (58...

Background: Malaria remains a major health problem in sub-Saharan Africa. One of the main challenges that researchers are facing eliminating parasite is chemoresistance to antimalarial drugs. Resistance artemisinin, molecule drug combinations used malaria treatment, has been observed Asia, as well Aims: The aim study susceptibility among rural population Bouna, Côte d’Ivoire, includes Fulani and understand influence mixed infections on this susceptibility. Methodology: This Cross-sectional...

Abstract Two Dioscorea alata populations were generated by hand pollination between contrasted diploid genitors. Population A (74F × Kabusa) was composed of 121 progenies while population B 14M) involved 193 progenies. These two assessed over consecutive years regarding important tuber quality traits. Analysis variance showed that the genotype had greatest influence on phenotypic scores. Also for some traits, effect year_replicate strong. The heritabilities most traits high. Based these data...

Landraces of maize (Zea mays L.) are invaluable sources genetic variability for improving agronomic traits, and they hold great promise in developing new varieties with enhanced resilience to stresses. Even though phenotypic characterization is an inexpensive approach elucidating variation hidden resources, information on the diversity patterns large collections landraces remains limited this constitutes a major impediment their optimal utilization modern breeding programs. We investigated...

Abstract Cowpea [ Vigna unguiculata (L.) Walp] is a globally important food security crop. However, it susceptible to pest and disease; hence, constant breeding efforts based on its diversity are required for improvement. The present study aims investigate the genetic diversity, population structure, linkage disequilibrium (LD) among 274 cowpea accessions from different origins. A total of 3,127 single nucleotide polymorphism (SNP) markers generated using array technology (DArT) was used....

Summary Inbreeding species of hermaphroditic animals practising copulation have been characterized by few copulations, no waiting time (the that an isolated individual waits for a partner before initiating reproduction compared with paired individuals) and limited inbreeding (self-fertilization) depression. This syndrome, which has never fully studied in any species, is analysed here the highly selfing freshwater snail Biomphalaria pfeifferi . We conducted experiment under laboratory...

Teak (Tectona grandis L.f; Verbenaceae) is a diploid species (2n=36). It native to the tropical deciduous forests of India, Myanmar, Thailand and Laos. Snuffed for its aesthetic physical properties qualities, teak becoming increasingly important in forest plantation development Côte d'Ivoire. To preserve genetic resources this ensure supply genetically superior quality germplasm improvement plantations, core collection genotypes with large diversity prerequisite. This paper reports use...

Human African Trypanosomiasis (HAT) or sleeping sickness is a Neglected Tropical Disease. Long regarded as an invariably fatal disease, there increasing evidence that infection by T. b. gambiense can result in wide range of clinical outcomes, including latent infections, which are long lasting infections with no parasites detectable microscopy. The determinants this diversity not well understood but could be due part to parasite host genetic multiple genes, their interactions. A candidate...

Methods Blood samples from 292 aged seven to 15 years were collected four nearby villages located at altitudes ranging 340 883 m above sea level....

Asymptomatic carriers of Plasmodium are considered a reservoir the parasite in humans. Therefore, order to be effective, new malaria elimination strategies must take these targets into account. The aim this study was analyse genetic diversity falciparum among schoolchildren three epidemiological areas Côte d'Ivoire.

Cowpea (Vigna unguiculata (L.) Walp) is a highly nutritious grain legume crop in the world. However, cowpea production constrained by pod borer (Maruca vitrata Fabricius) (LPB), which feeds on various parts of plant, causing complete failure. An analysis existing literature revealed LPB as serious threat to worldwide, with more noticeable damage Africa. Attempts develop and use LPB-resistant varieties have not shown significant results because challenges, such interspecific crossing...

Abstract While many molecular studies have documented arbuscular mycorrhizal fungi (AMF) communities in temperate ecosystems, very few exist which techniques been used to study tropical AMF communities. Understanding the composition of areas gains special relevance as crop productivity typically low fertility soils can be improved with use AMF. We a hierarchical sampling approach we sampled soil from cocoa ( Theobroma cacao L.) plantations nested localities, and localities were within each...

Despite the importance of yam ( Dioscorea spp.) tuber quality traits, and more precisely texture attributes, high-throughput screening methods for varietal selection are still lacking. This study sets out to define profile good pounded provide tools based on predictive models using near infrared reflectance spectroscopy. Seventy-four 216 studied samples proved be moldable, i.e. suitable yam. While with low dry matter (&lt;25%), high sugar (&gt;4%) protein (&gt;6%) contents, hardness (&lt;5...

The Solanum aethiopicum Gilo group, described as homogeneous, shows a high diversity, at least the morphological level. In Côte d’Ivoire, farmers distinguish three subgroups, named “N’Drowa”, “Klogbo” and “Gnangnan”, within this group. Data were obtained from 10 quantitative 14 qualitative morpho-agronomic traits measured in 326 accessions of eggplants, flowering fruiting stages. Univariate multivariate analyses allowed clearly clustering studied into subgroups. Fruit taste, leaf blade...

There is evidence that the knockdown resistance gene (Kdr) L1014F and acetylcholinesterase-1 (Ace-1R) G119S mutations involved in pyrethroid carbamate Anopheles gambiae influence malaria transmission sub-Saharan Africa. This likely due to changes behaviour, life history vector competence capacity of An. gambiae. In present study, performed as part a two-arm cluster randomized controlled trial evaluating impact household screening plus novel insecticide delivery system (In2Care Eave Tubes),...
