Abstract:

Nutritional counseling disseminated by biomedicine during prenatal consultations is of particular importance in the context of reproductive health. These advices are given to the pregnant woman in order to prevent all forms of food imbalances that could harm her as well as the fetus. This is why it is essential for pregnant women to take this into account. But at the Ébrié akouai in Bingerville, pregnant women must also respect traditional food norms. The existence of this traditional diet is not without effects on nutritional counseling. These effects are manifold and result in noncompliance with nutritional recommendations. At the same time, they show the limits of the nutrition education of pregnant. We have tried to discover them through individual conversations, focus group and direct observations.

Abstract:

Eleven samples of Chrysichthys nigrodigitatus and one sample of C. maurus were studied using morphometrics and enzyme polymorphism. Samples from opposite areas in the range of the species were most differentiated morphologically (Dagana in Senegal and Selingue in Mali, on one hand, and Bas Kouilou in Congo, on the other hand). In the sample from Bas Kouilou, most specimens overlap those from Ebrie Lagoon in Côte d'Ivoire. The populations from Côte d'Ivoire are genetically the most variable and have the highest number of alleles in common with the sample of C. maurus (ancestral alleles). The samples from the limits of the species' range (Dagana, Bas Kouilou) are those that have the least polymorphism (both monomorphs) and the fewest alleles in common with C. maurus. On the basis of these results we present a hypothetical scenario for the colonization of basins by populations of C. nigrodigitatus after the last glaciation. Colonization started in the area between Côte d'Ivoire and Benin. From this region of origin, some populations colonized the basins to the west via the coastal area up to Senegal. Independently, other populations colonized the basins to the east via the coastal area up to Zaïre. The colonization of the Niger most likely occurred through its Lower Delta.

Abstract:

Aquatic pollution in Côte d'Ivoire is severe in several places. The Ivorian government therefore requested and later obtained technical assistance from the Danish government for the training of personnel and the equipment of an environmental central laboratory and of a pollution combating unit. The structure CIAPOL (Centre Ivorian Anti-Pollution) in charge of setting up the two components of the project, was created by the government of Côte d'Ivoire in May 1991. A coastal and a continental monitoring network have been implemented. Nutrients, heavy metals, pesticides, hydrocarbons and microbiological methods have been adapted for the survey programs of water, sediment and biota. Results presented in this paper show spatiotemporal variations of the ammonia concentrations in the lagoon waters. Very high concentrations in the Bietry bay of hydrocarbons in sediment and zinc in oysters trace petroleum refinery pollution. The extremely high microbiological contamination of the lagoon water around Abidjan should preclude its use for any purpose. The staff of the centre has been trained in the use of the oil spill recovery equipment. Alert procedures and communications have been introduced. Today the CIAPOL is involved in national conventions and international projects. It is designated to become the Reference Laboratory in the region and will be in charge of training and intercalibration sessions within these projects.

Abstract:

Abstract This study focused on the diversity of fish fauna, its conservation status and its vulnerability in the Aghien freshwater lagoon (southeast of Côte d'Ivoire). For the fish data collection, two sampling approaches were used: experimental fishing and artisanal fishing. As a result, 80 species observed in this lagoon are distributed into 55 genera, 27 families and 10 orders. The best represented orders are the Perciformes, Siluriformes, Osteoglossiformes, Characiformes, Cyprinodontiformes and Pleuronectiformes. The Cichlidae, Mormyridae and Clupeidae represented the best diversified family. With an occurrence of 100%, the most frequent species are: Brycinus longipinnis, Chrysichthys nigrodigitatus, Pellonula leonensis, Schilbe intermedius and S. mandibularis. In the whole fish population, according to IUCN red list, four species where described as Near Threatened (Coptodon walteri, Marcusenius furcidens, Galeoides decadactylus and Cynoglossus senegalensis), four as Vulnerable (B. brevis, Rhexipanchax nimbaensis, Enteromius raimbaulti and Tilapia busumana) and one as Endangered species (Pseudotolithus senegalensis). These categories of species that have a conservation interest according to the IUCN Red List represent respectively 10.26% of the whole population. Fish population of the Aghien Lagoon are divided into seven classes ranging from “low” to “very high” vulnerability, regarding the vulnerability to stress due to fishing pressure.

Abstract:

Coptodon hybride est un poisson issu des croisements naturels entre Coptodon zillii X Coptodon guineensis. La présente étude a pour objectif de caractériser les habitudes et les stratégies alimentaires de ce poisson, en fonction de la taille des individus, des stations d’échantillonnage et des saisons hydrologiques dans la lagune Ebrié (Côte d’Ivoire). Sur un total de 323 individus (65< longueur standard ≤ 225 mm) capturés d’août 2014 à juillet 2015 avec des filets maillants, 236 tubes digestifs contenaient des proies et 87 étaient vides (26,93%). L’Indice d’Importance Relative (%IRI) qui prend en compte les pourcentages d’occurrence, numérique et pondérale, a été utilisé pour évaluer l’importance relative des différentes catégories de proies dans les tubes digestifs. Cinq groupes de proies ont été identifiés : insectes, zooplancton, crustacés, phytoplancton et plantes terrestres. Le régime alimentaire de Coptodon hybride est essentiellement constitué de plantes terrestres, surtout de débris végétaux (91,53% de l’IRI). L’analyse du coefficient de corrélation de Spearman montre une variation du régime en fonction de la taille et des stations. Cependant, il n’y a pas d’influences significatives des saisons sur l’alimentation des individus de petites tailles (65-129 mm) et ceux de grandes tailles (130-225 mm).Mots clés: Habitudes alimentaires, Coptodon hybride, lagune Ebrié, Côte d’Ivoire.

Abstract:

We assessed the infection risks related to the use of wastewater in Abidjan, Côte d'Ivoire, by using quantitative microbial risk assessment (QMRA). Giardia lamblia and Escherichia coli were isolated and identified in wastewater samples from the canal and lagoon. The exposure assessment was conducted using a cross-sectional survey by questionnaire with 150 individuals who were in contact with the wastewater during their daily activities of swimming, fishing, washing, and collecting materials for reuse. Risk was characterised using the Monte Carlo simulation with 10,000 iterations. Results showed high contamination of water by G. lamblia and E. coli (12.8 CFU/100 mL to 2.97 × 104CFU/100 mL and from 0 cyst/L to 18.5 cysts/L, respectively). Estimates of yearly average infection risks for E. coli (90.07–99.90%, assuming that 8% of E. coli were E. coli O157:H7) and G. lamblia (9.4–34.78%) were much higher than the acceptable risk (10−4). These results suggest the need for wastewater treatment plants, raising awareness in the population in contact with urban wastewater and lagoon water. Our study also showed that QMRA is appropriate to study health risks in settings with limited data and budget resources.

Abstract:

Background: Lagoons and wastewater constitute aquatics environments which receive or accounts for most domestic discharges. These waters constitute an important ecosystem for the proliferation of microorganisms. The microorganisms that harbor these waters can provide information on the persistence of certain diseases in the human population, including gastrointestinal infections such as Cholera. The genus Vibrio contains pathogenic aquatic bacteria found in lagoon bays and wastewater. Objective: The main objectives of this work were to confirm the presence of Vibrio spp. in lagoon bays and sewage of the city of Abidjan over the entire interepidemic period, and to evaluate their sensitivity to commonly used antibiotics. Methods: The isolation and identification of the microorganisms were carried out using classical bacteriological techniques (biochemical test, API 20E gallery). When necessary, serotyping was carried out using agglutination tests on slides. Antibiotic susceptibility testing was carried out using the Kirby-Bauer disk diffusion (KBDD) method. Results: This study identified 12 bacterial strains, 9/12 (75%) of which were Vibrio sp. strains. Two Vibrio species, namely Vibrio parahaemolyticus 2/9 (22%) and 7/9 Vibrio cholerae (78%) were identified. V. cholerae was isolated from both sewage and lagoon waters with dominance of serotype O1. The V. cholerae O1 and non-O1 strains showed a high level of resistance to sulfonamides, quinolones, fluoroquinolones, and moderate sensitivity to penicillins and tetracyclines. Resistant V. parahaemolyticus strains were also identified. Conclusion: The increased resistance of these bacteria could pose potential problems in the treatment of epidemics and other communicable diseases. The emergence of these multi-drug resistant strains of the genus Vibrio should prompt the Ivorian health authorities to maintain an epidemiological surveillance network for waterborne diseases throughout the country and to continue bacteriological sampling to monitor Vibrio's sensitivity to antibiotics.

Abstract:

This study is set within the important framework of the imperative need to safeguard traditional knowledge at historical, nutritional levels, and as an element of sustainable management of natural resources. Thus, it aimed to identify, through four ethnobotanical surveys (2007, 2009, 2015 and 2019), the wild edible plants used by the Ehotilé around the Aby Lagoon, on the Ivorian eastern littoral, to evaluate the use, preference and availability related to these plants and to discuss the evolution of food practices since the observations of missionaries three centuries earlier. The level of knowledge was analysed using Smith's Index and the availability of edible fruits was assessed with a new cognitive index. Compared to the era of the first settlement, the diet of the Ehotilé has undergone many modifications. Current observations showed that wild plants were rarely used in the diet which was essentially cassava-based. Thirty-nine edible ethnospecies corresponding to 40 scientific plants species were recorded for 46 uses, of which, wild fruits with 54.17 % were the most important. Edible fruits were available all year round, but irregularly and the availability index suggested that 10 species of the fruits sought were rare in the region. The study has shown that gathering plants are well known by the Ehotilé. However, they are not very present in their diet. In addition, they have a good knowledge of the availability of their edible plants and could therefore be key resource persons in any assessment of the dynamics of plants in their environment.

Abstract:

Abstract The aim of this study was to assess radio activity and elements levels of Ebrié lagoon water in Abidjan, Côte d'Ivoire. Eight bottles of water from Ebrié lagoon were taken for the study. This study was achieved by measuring of the activity concentration of 238U, 40K, and 232Th in Ebrié lagoon water samples using gamma spectrometry. Elements contents were determined too by Absorption Atomic Spectrometry technique. The activity concentrations of these radionuclides show that populations in these townships-villages are permanently exposed to diseases caused by the ionizing rays. The elemental analysis showed that the potential source of the pollutants is anthropogenic, intrusion from industrial and agricultural activities, materials and lubricants used near the lagoon are important factors of the pollution in this lagoon.

Abstract:

Sectors IV and V of the Ebrié lagoon are increasingly experiencing fish mortality. The abundance biomass comparison (ABC) is graphical method use to assess the level of environmental disturbance in this area. The aim of the study were to detect the environmental changes caused by anthropogenic activities using ABC curve of benthic macroinvertebrate assemblages presented in the studied areas. Results of the ABC analyses indicated that stations L, K and M are less stressed with biomass curve above abundance curve. Stations N and A recorded a stressed environment with abundance curve above biomass curve. The ABC plots showed that N and A stations could be classified as moderately disturbed and polluted. The Clarke's W index to the benthic macroinvertebrates data, confirmed this situation; it ranged from -0,129 (N) to 0,224 (L). The results of the present study can be extrapolated to other tropical wetland systems to predict the levels of disturbance and to identify characteristic organisms to predict the environmental conditions in the wetland health assessment program.

Abstract:

The early Miocene palynoflora was recovered from well P1 located in the Aboisso area, about 175 km around of Abidjan (south-eastern Côte d'Ivoire, West Africa). Pteridophyta spores, angiosperm and gymnosperm pollen grains have been identified. The main objective of this work is to inventory all the palynomorphs encountered, to propose a local palynostratigraphy and to reconstitute the paleobotany of our study area during the Tertiary formations north of the lagoon fault. The samples were processed according to the classical procedure of extraction and concentration of palynomorphs. The lithology contains brown to black clays, coarse to fine sands, and reddish to motley clays. This study showed that the dominance of freshwater ferns such as Verrucatosporites usmensis, Laevigatosporites ovatus, Polypodiaceiosporites simplex, Cingulatisporites pseudocicatricosus and leiotriletes adriensis which evokes a swampy environment. Also the development of Bombacaceae (Bombacacidites annae), and the abundance of Pteridophyte spores of the Polypodiaceae family (Verrucatosporites usmensis, Laevigatosporites ovatus, and Polypodiaceiosporites simplex) indicate the climate was tropical with alternating dry and wet periods. Early Miocene sediments are placed in a continental type environment.
