A survey of gastrointestinal parasites in Ogun State, southwest Nigeria

To study the epidemiology of intestinal parasites in Ogun State, Nigeria, 479 stool specimens were examined at a hospital in Abeokuta during the rainy season in June 1986. Intestinal helminths and/or protozoa were present in 297 samples (62%). 41.1% of the specimens showed a single infection, 34% showed double, 20% triple and 5% quadruple infection. The most commonly found worm was Ascaris lumbricoides (in 40% of specimens), followed by Trichuris trichiura (23.2%), hookworms (19.2%), Strongyloides stercoralis (2.1%) and Dicrocoelium sp. (0.4%). Pathogenic protozoa found were Entamoeba histolytica (7%), Giardia intestinalis (4.2%), Blastocystis hominis (2.5%) and Cryptosporidum sp. (2.3%). The apathogenic protozoa Entamoeba coli, Chilomastix mesnili, Trichomonas hominis and Iodamoeba buetschlii were also seen.     

Prevalence of Blastocystis hominis infection in asymptomatic individuals from Bangkok, Thailand

Fresh stool examination was performed from 2,230 participants who enrolled in annual check-up programs of the Faculty of Medical Technology, Mahidol University in 1999-2000 and 2004. In this study, Blastocystis hominis infection was diagnosed by culturing in Jones' media. A total of 21% of fecal specimens (in 1999-2000) and 13.7% (in 2004) were positive for B. hominis. The vacuolated form was the predominant form found in culture solution after 48 hours of incubation. The distribution of infection was highest between the ages of 21-30 years (p<0.05). There was no significant difference in infection between male and female groups. Other parasites, eg Giardia lamblia, Entamoeba histolytica, Entamoeba coli, Endolimax nana, Trichomonas hominis, Strongyloides stercoralis, Opisthorchis viverrini and Taenia species, were also found by fresh stool examination.     

Blastocystosis and other intestinal protozoan infections in human riverside communities of the Valdivia River basin, Chile]

Between March and October 1987, the prevalence of infection by Blastocystis hominis and other intestinal protozoan, their relationship with the age and sex of the hosts, and the percentage of infected persons in family groups were determined in riverside communities of Valdivia River Basin, Chile. One or more intestinal protozoan species were determined in 72.5% of the examined persons. The prevalence was greater for B. hominis (61.8%). The prevalences of B. hominis, Endolimax nana and Entamoeba coli were greater in relation to the age of the host. The sex of the host and prevalence of infections by B. hominis and other species of intestinal protozoans did not show association. Prevalence of B. hominis was greater in persons from houses with no sanitary faeces disposal. Over 60% of the members of family groups showed infection by B. hominis in 53.1% of the groups compared to 2.4%-21.8% of infections by other protozoan species. Faecal samples of 45 pigs revealed 22.2% of infection by Blastocystis.

Giardiasis and amoebiasis infections in three Saudi closed communities

Two hundred and eighteen residents (131 healthy and 87 mentally or physically retarded) of a children's nursery, a foster house and a rehabilitation centre for the handicapped in Abha, southwestern Saudi Arabia, were examined for intestinal parasitism. About 30% of the population of the three communities were found to harbour asymptomatic infections with either Giardia lamblia and/or Entamoeba spp. Giardia cysts were identified in 19.3% of those examined. Entamoeba histolytica was found in 18.4% of the residents of the rehabilitation centre only. Entamoeba coli infections were found in residents of both the foster house and rehabilitation centre (6.0 and 25.3% respectively). The prevalence of infection with the three parasites was significantly higher in the rehabilitation centre than in the children's nursery and foster house.
