Prevalence Of African Giant Snails For Parasites In A South-East Region Of Côte d'Ivoire

Two species of snails (Achatina achatina and Archachatina ventricosa), from surrounding forest of Azaguié’s district, were collected at the market of the locality aforementioned in order to identify their various parasites. For that, 50 snails of each species were sacrificed. Parasites were searched on the level of the flesh, between the flesh and the shell, the stomach, the intestine, the liver and the reproductive apparatus. The collected parasites were Balantidium spp, the larvae of Protostrongylus spp, the larvae of Dicrocoelium spp and Trichomonas spp. Our results showed that 52% of Achatina achatina and 74% of Archachatina ventricosa were parasitized. Among the parasites collected in the snail Achatina achatina, 95.8% were nematodes and 4.1% were trematodes. Whereas in the snail Archachatina ventricosa, 97.7% were protozoa, 8.8% nematodes and 0.4% consisting with trematodes. The prevalence of Protostrongylus spp (48%) were higher than that of Dicrocoelium spp (4%) in Achatina achatina. For the snail Archachatina ventricosa, the prevalence of parasite were dominated by Trichomonas spp (38%) and Protostrongylus spp (24%)

Efficacité parasitologique de l’albendazole sur les nématodes gastro-intestinaux du caprin nain (Capra aegagrus hircus) dans le Sud et le Centre-Est de la Côte d’Ivoire

In order to contribute to the fight against gastrointestinal parasites of dwarf goat in Ivory Coast, an in vivo sensitivity of nematodes test was conducted on 239 goats from 17 farms.  The drug used was albendazole. The Willis flotation and the McMaster method were used to determine, respectively, the presence of nematodes in goats and parasite loads before and after treatement control. The results revealed a high efficiency of albendazole against nematodes at all experimental sites. The minimum percentage reduction of excreted eggs was estimated at 99.4%. These results highlight the low prevalence of albendazole-resistant nematodes in goat populations in the South and Center-East of Ivory Coast.

La méthode de flottaison de Willis et celle de McMaster ont été utilisées pour déterminer, respectivement, la présence de nématodes chez les caprins et les charges parasitaires avant et après le traitement antiparasitaire. Les résultats ont révélé une forte efficacité de l’albendazole face aux nématodes sur tous les sites de l’expérimentation avec un pourcentage de réduction minimum des œufs excrétés estimé à 99,4%. Ces résultats mettent en évidence la faible prévalence des nématodes résistants à l’albendazole, au sein des populations caprines dans le Sud et Centre-Est de la Côte d’Ivoire.
