Abstract(s)
A parasitological study on non-human primates was performed during a biodiversity study at the Natural Park of the Lagoons of Cufada (Guinea-Bissau, West Africa), on February-March 2001 and October- November 2002.
The PRIMATES hosts observed were Cercopithecus mona campbelli (mona monkey), Chlorocebus aethiops sabeus (mangroove monkey), Papio cynocephalus papio (yellow baboon) e Procolobus badius temminckii (red colobus), which were caught by tradicional trapping.
The helminths were collected after a decanting process and fixation in alcohol 70º. The morphobiometrical studies were performed on specimens clarified by lactofenol (NEMATODA, PENTASTOMIDA and ARTHROPODA) and stained by chloridrical alcoholic carmin (PLATYHELMINTHES).
PHYLLA PLATYHELMINTHES (TREMATODA - Dicrocoelium hospes, Watsonius watsoni - and CESTODA – Bertiella studeri), NEMATODA (ENOPLIDA - Trichuris trichuria; SRONGYLIDA – Strongyloides fuelleborni, Ternidens deminuta, Oesophagostomum bifurcum, O. stephanostomum, Globocephalus longenucronatus, Pithecostrongylus sp., Hyostrongylus rubidus, ASCARIDIDA – Subulura distans; RHABDITIDA – Enterobius sp., and SPIRURIDA), PENTASTOMIDA (Armillifer armillatus) and ARTHROPODA (INSECTA – DIPTERA: first and second stages larvae of BRACHYCERA) were identified. Oesophagostomum stephanostomum and Hyostrongylus rubidus are new record for non-human primates from Guinea-Bissau.
All the primates species were infected and NEMATODA was the most abundant and diverse parasitic group. The results obtained showed distinct diversity rates, probably connected with the nutritional habits of the different hosts.
The helminthological fauna knowledge on non-human PRIMATES, in a ecosystem such as the Natural Park under study, has major importance due to the relationship established by helminths, wild fauna and environment, as well as its potential transmissibility to man, which will depauperate the sanitary conditions of local populations.
