Entamoeba histolytica and other parasitic infections in south Kanara district, Karnataka

Single stool specimens collected from 1,020 apparently healthy people of the South Kanara District, were processed for intestinal parasites using three parasitological methods viz. (a) Direct smear in physiological saline and D'Antoni's iodine, (b) Zinc sulfate concentration method and (c) by culture in modified Boek and Drbolhav medium. Of these 781 (76.51 per cent) were found to be infected with parasites. The prevalence of various intestinal parasites was: Ascaris lumbricoides (48.33 per cent), Necator americanus (46.86 per cent), Trichuris trichiura (42.75 per cent), Entamoeba coli (23.24 per cent), Entamoeba histolytica (7.94 per cent), Enterobius vermicularis (2.84 per cent), Giardia intestinalis (2.45 per cent), Iodamoeba buitschlii (1.57 per cent), Entamoeba hartmanni (1.37 per cent), Trichomonas hominis (0.88 per cent), Strongyloides stercoralis (0.68 per cent), Hymenolepis nana (0.49 per cent), Chilomastis mesnili (0.10 per cent) and Endolimax nana (0.10 per cent). High incidence of parasitic infections was recorded in females and age group of 6-14 years.

Human parasitoses of the Malili area, South Sulawesi (Celebes) province, Indonesia.

A biomedical survey was conducted in 9 villages in the Malili area of South Sulawesi, Indonesia. Blood specimens were examined for malaria and microfilariae; stool specimens were examined for intestinal parasites. Malaria parasitemias were rare; Plasmodium falciparum was detected in 10 and P. vivax in 11 of 985 blood smears. Malayan filariasis was endemic to all villages surveyed. The overall prevalence of detectable microfilaremias was 15%, varying from 34% in Kawata to 1% in Nuha. Microfilarial densities, expressed as MfD50 averaged 8.0 and varied from 1.1 in Timampu to 16.0 in Karabbe. Intestinal parasites were common. Although Schistosoma japonicum was not found, 97% of the examined had one or more intestinal parasites as follows: Ascaris lumbricoides (74%), Trichuris trichiura (65%), hookworm (62%), Entamoeba coli (38%), Endolimax nana (10%), Entamoeba histolytica (6%), Iodamoeba bütschlii (4%), Entamoeba hartmanni (3%), Giardia lamblia (2%) Chilomastix mesnili (1%) and Enterobius vermicularis (1%). Strongyloides stercoralis larvae and Hymenolepis nana eggs were detected once each and heterophyid-like eggs were detected twice.

Prevalence and seasonal fluctuations of intestinal parasitic infections in the Nablus area, West Bank of Jordan

A total of 22,970 stool specimens collected from patients attending the Central Medical Laboratory in the city of Nablus in the period of 1981-1986 were examined for intestinal parasites. Of these 7412 (32.3%) were positive. Entamoeba histolytica (22.9%), Giardia lamblia (7.3%), and Ascaris lumbricoides (5.7%) were the most prevalent intestinal parasites found. Other intestinal parasites present included Hymenolepis nana, Trichomonas hominis, Trichuris trichiura, Taenia saginata, Enterobius vermicularis and Strongyloides stercoralis. Seasonal occurrence of intestinal parasites in the West Bank of Jordan was also studied in the period January 1981-August 1987. Lower prevalence rates of intestinal parasites generally occurred during winter and early spring. Peak incidence occurred during summer and early autumn. The reasons for these seasonal variations are discussed.
