Résumé
Results of a serology survey in September 1972 for Entamoeba histolytica and Toxoplasma gondii antibodies among 915 volunteers from the Malili area of South Sulawesi (Celebes), Indonesia are presented. Indirect hemagglutination antibody titers for amoebiasis were found in 22.7% of the sampled population while 9.5% demonstrated antibody titers greater than or equal to 1:128. The frequency distribution of antibody titers were similar by sex and age. There was no significant correlation between stool positivity and seropositivity. Indirect hemagglutination antibody titers for T. gondii were detected in 62% of the population sampled, and titers greater than or equal to 1:32 were demonstrated in 29% of the samples tested. The distribution of antibody titers was similar in males and females. In both sexes the prevalence of IHA antibody titer against T. gondii increased with age. There was no consistent association between altitude and prevalence of seropositive samples.

Pediatric patients with fever and haemorrhage were studied in Jakarta, Indonesia between May 1973 and January 1974. Eighty-one of 104 demonstrated unequivocable evidence of dengue with clinical findings similar to those reported associated with dengue haemorrhagic fever in Thailand. The majority of patients had extremely high antibody titers against dengue measured by both hemagglutination-inhibition and by plaque reduction neutralization tests and all four types of dengue virus were isolated. Eight of the patients died.
