Distribution spatio-temporelle de la pression du braconnage sur Eidolon helvum (Kerr, 1792), espèce proche de la menace (Côte d’Ivoire, Afrique de l’Ouest)

Objectifs: Cette étude vise à étudier la répartition dans l’espace et dans le temps de l’activité de braconnage sur les chauves-souris paillées (qui rendent d’importants services écosystémiques), Eidolon helvum (Kerr, 1792), espèce proche de la menace, de la commune du Plateau (Abidjan, Côte d’Ivoire) afin de dégager des implications pour sa conservation.Méthodologie et résultats: Un suivi hebdomadaire de la dynamique de cette activité dans les 16 sites dortoirs des chauves-souris paillées a été réalisé d’août 2005 à juillet 2006 pour déterminer sa distribution spatiale et temporelle. Les résultats indiquent que la pression de braconnage a été forte au site 3, moyenne au site 8 et faible sur les autres sites. La pression du braconnage a varié avec le site et la saison.Conclusion et application: Cette étude contribue à une meilleure connaissance de l’écologie de cette espèce de chauve-souris proche de la menace et fournie des données préliminaires sur la distribution de l’intensité de l’activité du braconnage. Pour assurer l’intégrité de cette population, ces données serviront de base pour la mise en place d’une politique de préservation de cette espèce quasi-menacée.Mots-clés: Milieu urbain, chauves-souris paillées, braconnage, effet de la saison, conservationEnglish Title: Spatiotemporal distribution of poaching pressure on Eidolon helvum (Kerr, 1792) near-threatened species (Côte d’Ivoire, West Africa)English AbstractObjectives: The study was on repartition (time and space) of poaching activity on straw-colored fruit bats (provide important ecosystem services) Eidolon helvum (Kerr, 1792), a near-threatened species in the District of Plateau in Abidjan (Côte d’Ivoire) in order to draw a practical applications in relation to their preservation.Methodology and Results: Weekly monitoring of the dynamic of poaching activities in roosting sites was made from August 2005 to July 2006. Results show that the poaching pressure was high at site 3, moderate at site 8 and weak on other sites. Poaching pressure varied with the site and season.Conclusions and application of findings: The present study is a contribution to a better knowledge of Chiropters and provides preliminary ecological data on poaching intensity distribution. Poaching data should be increase  and incorporated or integrate into biodiversity system preservation strategy in order to ensure a rational and sustainable management of that near-threatened species.Keywords: Urban area, straw-colored fruit bats, poaching, season effect, conservatio

Ressources Alimentaires De Eidolon helvum (Kerr, 1792), Espece Proche De La Menace (Abidjan, Côte d’Ivoire)

Food resources of the straw-colored fruit bats Eidolon helvum (Kerr, 1792), a near-threaned species in Abidjan-Plateau were studied from August 2007 to July 2008. Faeces collection under sleeping trees and direct observations were made in order to access qualitative composition and temporal distribution of food resources of Eidolon helvum. Results show that 16 species of plants grouped into eight families and classified in three categories of plant organs were exploited by these bats. Among them, three species of plants appeared for the first time in the diet of the frugivorous bats in Côte d’Ivoire. Fruit food resources were most abundant (83%) and fruits of Ficus genus were dominant (45%). The distribution of food resources varied with the season

Prevalence and Intensity of Intestinal Parasites and Malaria in Pregnant Women at Abobo District in Abidjan, Côte d’Ivoire

A prospective study was carried out from 2010 to 2012 at the Hôpital Général d’Abobo (HGA) in Abidjan, in order to determine the impact of infectious and parasitic diseases on child cognitive development. Blood samples were examined by means of drop thick and blood smear, as for stool by direct examination and concentration by formalin-ether method. We evaluated the prevalence and the parasite load of malaria and gastrointestinal parasites and then investigated the risk factors for these disorders. Overall, 331 pregnant women in the last trimester of their pregnancy were enrolled. The plasmodic index was 3.9% with an infestation specific rate for P. falciparum of 100%. Concerning digestive protozoa, it has been observed 71.3% of nonpathogenic, against 9.7% of pathogens, either an overall prevalence of 51.4% of digestive parasites. The calculated average parasitic loads revealed 3089.2 tpz/μl of blood (95% CI, 591.1–5587.3) for malaria, 6.5 eggs per gram of stool (95% CI, 0.4–13.4) for intestinal helminths, and one (1) parasite by microscopic field for protozoa (common infestation). It has been shown that the occurrence of malaria has been linked to the nonuse of impregnated mosquito nets (χ2 = 0.012, p = 0.018) to age. No link could be established between the presence of digestive parasites and the age of pregnant women or socioeconomic conditions (level of education, profession, type of toilet). Malaria is less common in pregnant women, while the rate of digestive parasites remains high
