Rickettsia tsutsugamushi was isolated from L. (L.) arenicola chiggers and three species of rats in an area of scrub and sedge along the Bay of Jakarta. This is the only finding in Indonesia of a cycle of the agent of scrub typhus associated with L. (L.) arenicola. A serologic survey of nearly 300 persons living in two kampungs near the site at which rickettsiae were recovered revealed one individual with antibodies to R. tsutsugamushi. Murine typhus, with a seropositivity rate of 6.5%, may be endemic at low levels.

A survey of intestinal and blood parasites of man was conducted on the island of Bali, Indonesia in 1974. A total of 270 stool specimens from three villages were examined. Both Ascaris lumbricoides and Trichuris trichiura were found in more than 90% of those examined, and hookworm eggs in 59%. Other intestinal helminth and protozoan parasites found were: Enterobius vermicularis, Entamoeba histolytica, Entamoeba coli, Endolimax nana, and Iodamoeba bütschlii. Taeniid proglottids, Hymenolepis diminuta and dicrocoeliid-like trematode eggs were each found once. No microfilariae were found in 284 blood smears examined, however, in the village of Kusamba, Plasmodium vivax (3 cases) and Plasmodium falciparum (2 cases) were diagnosed.
