    Les affections parasitaires sĂ©vissent dans les pays en voie de dĂ©veloppement, en particulier au sein des populations pauvres des rĂ©gions tropicales. En CĂŽte d’Ivoire, des prĂ©cĂ©dents travaux ont montrĂ© des taux de prĂ©valence Ă©levĂ©s pour les infestations parasitaires intestinales. Le but de notre Ă©tude Ă©tait d’investiguer sur la prĂ©sence des parasites gastro-intestinaux chez les populations de 3 villages situĂ©s autour du parc national de TaĂŻ (PNT) ainsi que chez les chercheurs et les assistants de recherche travaillant au sein du PNT. L’analyse de 586 Ă©chantillons de selles par la mĂ©thode de Ritchie et par la technique de concentration Merthiolate-Iodine-Formaldehyde (MIF) a mis en Ă©vidence la prĂ©sence de 21 parasites dont 12 helminthes et 9 protozoaires. Les prĂ©valences parasitaires globales Ă©taient Ă©lĂ©vĂ©es (69,1%) dans l’ensemble des sites Ă©chantillonnĂ©s. Les prĂ©valences parasitaires globales Ă©taient Ă©lĂ©vĂ©es (69,1%) dans l’ensemble des sites Ă©chantillonnĂ©s. Le village de GoulĂ©ako 1 a enregistrĂ© la prĂ©valence parasitaire globale la plus Ă©levĂ©e (81,43%), et le vilage de PaulĂ© Oula la plus faible (64,58%). Les individus de la classe d’ñge [7-14ans] Ă©taient les plus infestĂ©s avec un pic d’infestations pendant la saison pluvieuse. Le polyparasitisme est trĂšs marquĂ© avec 89% des sujets infestĂ©s par au moins deux espĂšces de parasites. L’inventaire faunistique des parasites intestinaux des populations humaines vivant Ă  proximitĂ© du PNT a permis de rajouter six nouvelles espĂšces Ă  la liste des parasites identifiĂ©s chez les populations de CĂŽte d’Ivoire. Il s’agit d’Oesophagostomum sp., de Capillariidae Gen. sp. 2, de Dicrocoelium sp., de Trichostrongylus sp., de Strongyloides fuelleborni et de Balantidium coli. Parasitic diseases are prevalent in developing countries, especially among poor communities in the tropics. In CĂŽte d'Ivoire, previous studies have recorded high prevalence for intestinal parasite infestations. This paper focuses on investigating the presence of gastro-intestinal parasites in rural populations from 3 villages located near the Tai National Park (TNP) and among researchers and research assistants working in TNP. Screening of 586 stool samples by Ritchie method and Merthiolate-Iodine-Formaldehyde concentration technique has revealed the presence of 21 parasites including 12 helminths and 9 protozoa. The overall parasite prevalence was high (69.1%). We found the highest and lowest prevalence in GoulĂ©ako 1 (81.43%) and Paule Oula (64.58%) villages respectively. The age group [7-14] has been more infested with a peak of infestations during rainy season. Polyparasitism is very marked with 89% of individuals harboring at least two species of parasites. The intestinal parasites inventory, detected in rural populations living near the PNT, allowed us to add six species to the list of parasites identified in the human population of CĂŽte d'Ivoire. These are Oesophagostomum sp., Capillariidae Gen. sp., 2 Dicrocoelium sp., Trichostrongylus sp., Strongyloides fuelleborni and Balantidium coli

    <p>Abstract</p> <p>Background</p> <p>With the aim of discovering new natural active extracts against malaria parasites, <it>Icacina senegalensis </it>was selected after an ethnopharmacological survey conducted on plants used in traditional malaria treatment in Senegal.</p> <p>Methods</p> <p>Different concentrations of the plant extract and fractions were tested on synchronized <it>Plasmodium falciparum </it>cultures at the ring stage using the parasite lactate dehydrogenase assay. Their haemolytic activity and <it>in vitro </it>cytoxicity were evaluated. The chromatographic profiles of active fractions were also established.</p> <p>Results</p> <p>The plant extract and fractions revealed anti-plasmodial activity (IC<sub>50 </sub>< 5 ÎŒg/mL) with no toxicity (Selectivity indexes >10). The dichloromethane fraction showed stronger anti-plasmodial activity than the total extract.</p> <p>Conclusion</p> <p>Anti-plasmodial activity and toxicity of <it>I. senegalensis </it>are reported for the first time and showed promising results in malaria field research.</p
