Abstract As part of a United Nations Children's Found (UN¬ICEF) study, an analytical method is proposed for routine analysis of vitamin A in milk and flour consumed by 1- to 4-year-old children in Côte d'Ivoire. The method involves liquid-liquid extrac¬tion of sample followed by reversed-phase liquid chromatography (LC). The method has been vali¬dated and used to analyze various samples col¬lected at different locations and stored under unfa¬vorable conditions. Average vitamin A content was 575 μg/100 g for milk powder and 1350 μg/100 g for millet flour. Lower contents were found in corn flour (40-240 μg/100 g), and no vitamin A could be detected in rice flour

AbstractThis article examines international responses to the post-election crisis in Côte d'Ivoire, where two distinct governments were established due to contradiction between the election results proclaimed domestically and those certified by the internationally entrusted authority observing the election. Between two competing authorities, the international community stood firmly in favour of the internationally recognized president-elect as ‘legitimate authority’ while acting against the opponent whom they considered to hold ‘illegitimate authority’. Considering the principle of democracy as the underlying rationale grounding the international responses, this article identifies three mechanisms that incorporate and thus promote the principle of democracy: international election monitoring as setting mechanism, international representation as consolidating mechanism, and international intervention as enforcing mechanism. In accordance with these analyses, the current stage of democracy in international legal discourse is queried, particularly the democratic entitlement of a government in relation to determination of its international legitimacy.

Aims: The aim of this work is to assess the level of aflatoxins contamination in maize produced in five regions (Poro, Hambol, Gontougo, Gbêkê, Indénié-Djuablin) of Côte d'Ivoire. Place and duration of study: In this study 375 samples of maize (grains, cobs, spathes) were taken from February 2016 to January 2017 and the aflatoxin analyses were carried out at the Biotechnology Laboratory, Agriculture and Development of Biological Resources of the Félix Houphouët-Boigny University. Methodology: The aflatoxins (B1, B2, G1 and G2) were extracted and assayed by High Performance Liquid Chromatography (HPLC) according to the AOAC method. Results: The results indicate the presence of aflatoxins B1, B2, G1 and G2 in all forms of maize (grains, cobs, spathes) and in the five regions chosen for the study. The mean concentrations of aflatoxins B1 (AFB1) and the total aflatoxins (AFT) varied from 0.79 ± 0.04 µg/kg to 130.31 ± 22.56 µg/kg and from 2.63 ± 2,35 µg/kg to 169.13 ± 40.39 µg/kg respectively. samples from Indénié-Djuablin, Hambol and Gountougo regions showed the highest proportions of non-compliance with the european Union limit of 5 μg/kg and 10 μg/kg. Regarding AFB1, these proportions vary from 0% to 46% in the regions of Gbêkê, Poro and Hambol, while they are between 54% and 96% in the regions of Indénié-Djuablin and Gontougo. For total aflatoxins, the proportions of non-compliant samples were between 0% and 40% (Gbêkê and Poro), 12% and 56% (Hambol), 56% and 96% (Indénié-Djuablin and Gontougo). Conclusion: These results demonstrate a need for monitoring of maize production by stakeholders in the sector who should adopt good agricultural practices.

In an ecosystem where ferrallitization is the dominant pedogenetic process, brown soils of a particular character are observed. They are dominant clay texture, very often spotted, and heavily loaded in coarse elements consisting of ferromanganic nodules and concretions. This paper focuses on highlighting the morphopedological and geochemical characteristics, determining the originality of the brown soils observed at Anikro and Kahankro, in the region of Toumodi, in Côte d’Ivoire. In the field, the toposquencial approach has been adopted. Soil pits have been opened and described. The samples taken were then analyzed by the triacid method in view of the determination of the content of total elements horizon by horizon. The results obtained show that the brown soils observed at Anikro and Kahankro are generally regosols and cambisols. They are subject to phenomena of reworking and rejuvenation and were affected by a phenomenon of hydromorphy at the bottom of the slope. The oxidation-reduction spots that occur in soil profiles and which predispose them to concretion are more abundant in topographic top and bottom position. Chemical analysis shows that at Anikro, the silica content decreases as the depth increases. Also, iron (Fe2O3) and aluminum (Al2O3) have an antagonistic character on the midslope. While at the bottom of slope, the MgO, MnO, Al2O3 and Fe2O3 contents increase in the BfeC depth horizon, with respective values of 3.6%, 2% and 20% for each of the last two. In Kahankro soils, the antagonism exists between silica and iron. Magnesium and manganese accumulate only in the surface horizons. At the lower slopes, the highest levels of iron (30%), aluminum (20%), magnesium (1.2%) and manganese (0.4%) in the Bg horizons begin with horizon A3. These high grades are obtained due to pseudogleyic to gleyic characters of soils located at this topographic position. The various oxides measured sometimes show a dispersed character according to the locality in relation to the nature of the rock formations whose alteration has been given to the soil. The various characteristics of the soils described reveal their particular characteristics. These soils deserve to be referred to as browned soils.

ThermophilicCampylobactersare major causes of gastroenteritis in human. The main risk factor of infection is consumption of contaminated or by cross-contaminated poultry meat. In Côte d’Ivoire, gastroenteritis is usually observed but no case of human campylobacteriosis has been formally reported to date. The aims of this study were to determine prevalence and antimicrobial resistance ofCampylobacter jejuniandCampylobacter coliisolated from chickens ceaca in commercial slaughter in Abidjan. Between May and November 2009, one hundred and nineteen (119) chicken caeca samples were collected and analyzed by passive filtration method followed by molecular identification (PCR). From these 119 samples, 76 (63.8%) were positive toCampylobactertests. Among the positive colonies, 51.3% wereC. jejuniand 48.7% wereC. coli. Of the 39C. jejuniisolates, 79.5%, 38.5%, 17.9%, 10.3%, and 7.7% were, respectively, resistant, to nalidixic acid, ciprofloxacin, amoxicillin, erythromycin, and gentamicin. Among the 37 isolates ofC. coli, 78.4%, 43.2%, 13.5%, 8.1%, and 0% were resistant, respectively, to the same antibiotics. In conclusion, we reported in this study the presence of highCampylobactercontamination of the studied chickens. Molecular identification of the bacteria was performed and determination of high resistance to antimicrobials of the fluoroquinolone family was revealed.

This research work was carried out on the species Nephrolepis biserrata (Sw.) Schott (Nephrolepidaceae), a fern from Côte d’Ivoire with the aim of establishing its phytochemical, antioxidant and biological profile. The results obtained from the phytochemical screening show that said species contains alkaloids, coumarins, flavonoids, polyphenols, sterols, terpenes, and tannins. The antioxidant activity was evaluated spectrophotometrically against the DPPH radical in comparison with that of vitamin C. The determination of the antibacterial parameters indicates that N. biserrata doesn’t exhibit any bactericidal action against the bacterial strains tested. Regarding the vermicidal activity against earthworms, decocts of N. biserrata showed an anthelmintic effect, which however remains less pronounced than that of albendazole, the anthelmintic antiparasitic taken as a reference. Keywords: Nephrolepis biserrata, phytochemical screening, antioxidant, antibacterial, vermicide.

Aims: This study aims to determine the fatty acid, sterol and total polyphenol composition of Ricinodendron heudelotii, Terminalia catappa, Moringa oleifera, Cyperus esculentus, Sesamum indicum and Coula edulis oils. Study Design: Plant material consisting of almonds of Ricinodendron. heudelotii, Terminalia catappa, Moringa oleifera, rhizomes of, Cyperus esculentus, seeds of Sesamum indicum and hazelnuts of Coula edulis were collected in different producing areas of Côte d'Ivoire in 2017. Place and Duration of Study: This study was conducted between November 2017 and June 2018 at the Laboratory of Industrial Processes, Synthesis, Environment and New Energies, National Polytechnic Institute Félix Houphouët-Boigny, Côte d'Ivoire. Methodology: The extraction of oil from the oil-bearing organs of different plants was carried out by maceration of the crushed parts of these organs in hexane at a crushed/solvent ratio of 1:10 (grams/volume) for 6 hours at cold temperature. These oils were analyzed by gas chromatography for the determination of fatty acid profile, then by gas chromatography coupled with a mass spectrometer for the determination of sterols and Ultraviolet-visible spectrophotometer for the quantification of polyphenols. Results: The results show a fatty acid composition of the different oils dominated by four fatty acids: oleic (18.89 - 93.93%), linoleic (1.03 - 43.2%), palmitic (2.65 - 35.6%) and stearic (1.09 - 11.66%). We also note average unsaponifiable matter (0.5 - 1.71%) and sterols dominated by sitosterol, stigmasterol and campesterol. Concerning polyphenols, the values obtained range from 52.09 to 863.67 µg gallic acid equivalent/g oil. Conclusion: The presence of sterols, phenolic compounds and unsaturated fatty acids in interesting proportions show that these oils are important sources of edible oils beneficial to human health.
