Abstract
The stool examinations on 205 Japanese living in Nairobi, Kenya, and 65 Kenyans working in the Japanese homes as an indoor-or outdoor servant, maid or driver were carried out in March, 1981. The Japanese group was composed of 143 adults (79 males and 64 females) and 62 children under 15 years old (33 males and 29 females). Most of them had been staying in Nairobi for 6 months or more. The Kenyan group was composed of 61 adults (33 males and 28 females) and 4 children. The stool specimens were examined by formol-ether sedimentation method followed by iodine-staining.
Out of 205 specimens from the Japanese group, only one case of Entamoeba coli infection and one case of Metagonimus yokogawai infection were detected. The latter case was suspected that the infection had occurred by ingestion of undercooked Ayu, a fresh water fish Plecoglosus altivelis, during his stay in Japan. On the other hand, out of 65 Kenyan persons 41 (63.1%) were infected with one or more intestinal parasite species. The parasite species detected and their infection rates were 16.9 per cent for Entamoeba histolytica, 16.9 per cent for E. coli, 26.2 per cent for Endolimax nana, 1.5 per cent for Iodamoeba butschlii, 1.5 per cent for Giardia lamblia, 4.6 per cent for Chilomastix mesnili, 3.1 per cent for Ascaris lumbricoides, 23.1 per cent for hookworm, 10.8 per cent for Trichuris trichiura, 3.1 per cent for Strongyloides stercoralis, 4.6 per cent for Schistosoma mansoni and 3.1 per cent for Taenia sp., respectively.
