Physico Chemical

This study examined the distribution of Escherichia coli (E. coli) resistant to eleven antibiotics and possible relationships among physico-chemical parameters and these resistances. It was carried out over two years during four climatic seasons in five lakes of the Yamoussoukro lake system in Côte d'Ivoire. The physicochemical parameters of the lakes studied are temperature, pH, dissolved oxygen (DO), dissolved organic carbon (DOC), turbidity, nitrates, orthophosphates and ammoniacal nitrogen. A total of 744 water samples were collected from five (5) lakes belonging to the lake system, over a two-year period, during four dry and four wet seasons. Escherichia coli loadings were evaluated after isolation on specific chromogenic medium COMPASS ECC Agar and the susceptibility to antibiotics by the agar diffusion method. Physico-chemical parameters were evaluated according to international standards. The physico-chemical results showed that the nutrient contents evolved generally from upstream to downstream of the lake system, independently of the sources of pollution of five lakes of system. However, the lake B, in upstream of the lake system, showed levels of nitrate, orthophosphate and ammoniacal nitrogen often similar to the downstream lakes. This demonstrates a source of chemical pollution in this lake, which flows to lakes D and E, which are themselves subject to other pollution. Bacterial loads and bacterial resistance to antibiotics have strictly evolved from upstream to downstream of the system. Most isolates were resistant to ampicillin (16.46%), tetracycline (12.87%), ciprofloxacin (12.86%) and sulfamethoxazole (10.14%). Antibiotic resistance patterns of E. coli isolates were similar in both years studied, but higher during rainy seasons (GRS and SRS). The spearman rank correlations and the principal component analysis (PCA) revealed significant correlations between bacterial resistance to antibiotics in lakes and water physico-chemical parameters. Turbidity and DOC can help to determine the main resistances in the lake D. Orthophosphates can help to understand the resistance of chloramphenicol and the nitrates can help to understand the resistance of ampicillin in the lake B. Resistance in the lakes A, B and C can be influenced by dissolved oxygen. Overall, this study provided baseline information on bacterial resistance in the lakes of Yamoussoukro in Côte d'Ivoire, showing that these lakes could be reservoirs of antibiotic resistance, potentially dangerous to public health.

Cocoa Tree

The cocoa tree is a very important plant in Côte d'Ivoire (formerly known as Ivory Coast) with a production of 2,15 million  tons. In spite of this performance, cocoa production is attacked by several pests of which the emerging ones are Pseudotheraptus devastans (Distant). These insects  attack  cherelles,  pods, gourmands and young shoots. This study aims to locate these pests and determine their importance in the different cocoa production areas. The device used is total  randomization. The leaching carried out in the orchard revealed the presence of P.devastans in all the cocoa producing districts. The means were 0,02 ± 0,00 to 2,35 ± 0,38 P. devastans  / tree.  The  districts of Sassandra-Marahoué, Comoé and Montagnes recorded  more  P.devastans.  However, the districts of Bas-Sassandra, Lagunes et Lacs had fewer P.devastans.

This article is an attempt to understand and analyze the difficulties encountered by agricultural cooperatives in the marketing of cola nuts. Despite the considerable capital generated by this sector, many difficulties are hampering the agricultural sector, which results in a sharp decline in the profits of cooperatives and producers. For the members, this is due to the lack or little commitment of the Ivorian State to revitalize this promising sector as is the case with the coffee-cocoa pair. In fact, the fact that foreign traders have direct access to growers in their production areas without going through a central structure, in particular the wholesale marketBouake, weakens domestic traders. Similarly, this situation prevents the Ivorian export circuit of Cola from having a substantial tonnage and allowing the entry of foreign currency into the country. All this contributes to devalue the label of the cola nut produced in Cote d'Ivoire.

If the culture of the cocoa in Côte d’Ivoire gives a great satisfaction concerning the production level, the quality of raw cocoa beans remains to be improved. One of the causes of this depreciation is the moulds development in beans. In order to identify responsible fungus, cocoa beens have been collected in the maine production areas which are the East, the Mid-West and the South-West, represented respectively by the localities of Abengourou, Oumé and Soubré. From collected beans, the fungus have been insulated and purified on PDA medium and then, they have been identified by observing their morphocultural and microscopic characteristics. The results show that 9 mushroom species belonging to 5 genera were identified in cocoa beans collected in the whole of the localities. There are Aspergillus, Penicillium, Fusarium, Curvularia and Streptomyces. Among them, the Aspergillus genus which is able to produce ochratoxine, was found with an appearance frequency of 86.30 %.
