RESUMEN
Blastocystis hominis has long been described as a non pathogenic protozoan parasite until recently when claims have been made that it can result in pathogenic conditions. Of the 729 stool samples (614 from survey and 115 from pediatric wards) examined, 18.1% of them were found to be positive for one or more intestinal protozoan cyst. The commonest was Giardia intestinalis (8.4%) Followed by Entamoeba coli (7.1%) and Entamoeba histolytica (5.1%) in the normal children without symptoms of diarrhea. When diarrheic stools were examined, the commonest parasite encountered was Giardia (20.4%), followed by E. coli (15.9%) and E. histolytica (9.7%). Blastocystis was observed in 4.4% of the children who had diarrhea and 1.1% among the children taken from the normal population in the rural areas.

A total of 736 sera collected from cord blood babies, children and adults of both sexes and of different age groups in Malaysia were tested using indirect fluorescent antibody technique for Toxoplasma antibodies. The RH strain of Toxoplasma gondii zoites were used as antigen. One hundred and twenty five sera which were reactive at 1:64 or high titres were tested with IgM specific conjugate. Results of the present studies showed that the prevalence of Toxoplasma antibody was highest among the Malays and lowest among children than among adults. The significance of Toxoplasma specific IgM was discussed.

A total of 2,337 rodents trapped from various parts of Peninsular Malaysia were dissected and studied for the distribution and prevalence of parasitic infections. Four new rodent hosts for Sarcocystis in Malaysia are reported (Bandicota indica, Rattus sabanus Rattus argentiventer and Rattus norvegicus). Sarcocystis was found in 17.2 percent of the rodents examined. Rattus annandalei, Rattus tiomanicus and Rattus norvegicus are new hosts of Syphacia muris in Peninsular Malsysia. Rattus sabanus was found to be infected with Zonorchis borneonenis. Brachylaima ratti Baugh, 1962 was recovered from the small intestine of Rattus rattus diardii for the first time in Malaysia. The prevalence and distribution of other parasites are also discussed.

A survey of workers and families resident in an oil palm estate in Malaysia revealed high incidence of parasitic infections. The commonest parasites are T. trichiura (56%), A. lumbricoides (52%), hookworm (28%), Entamoeba coli (11.3%) and Giardia lamblia (11.3%). Mixed infections by two or more parasites was seen in 46% of the subjects. Anaemia was present in 70% of children with hookworm infection. Eosinophilia was observed in 69% of subjects. One each of Hymenolepis nana and Hymenolepis diminuta infection was detected. This is the first report of Hymenolepis diminuta infection in man in Malaysia.
