Description

A parasitic helminths survey was carried out on the mongoose captured on Okinawajima Island, Japan between January 2002 and September 2008. Here we report the results of several preliminary examinations conducted by various methods. Initial fecal sample survey with ether-formalin sedimentation of 186 mongooses detected the eggs of Trichuris, Hookworm, and Ascarid, as well as Coccidium oocysts in 42.5%, 22.6%, 2.2%, and 81.2%, respectively, of the samples. Follow-up survey of mongooses (n=175) for Angiostrongylus cantonensis infection showed that the parasite was not found in the lung and heart of any of the mongooses. Further, no Trichinella sp. larvae were obtained from the diaphragm by the compression method (n=161) nor from the masseter muscle, diaphragm and the inside of hind leg by the artificial digestion method (n=144) in a survey conducted 5 years later. Based on the gastrointestinal sample (n=158) survey, three nematode specices (Protospirura sp. (0.6%), Uncinaria sp. (0.6%), Toxocara sp. (0.6%) and one cestode species (Mesocestoides sp. (3.8%) were detected. To examine the localization of coccidium within the alimentary tract, mongooses (n=8) were kept on a controlled diet for three days, and sacrificed. Coccidia were detected in the epithelium of the duodenum and ileum from paraffin-embedded sections of 2 individuals.
