ABSTRACT
One hundred and fifty one house rats, Rattus rattus diardii from five different localities, Jinjang, Dato Keramat, Kuala Lumpur, Sungai Besi and Selayang Baru, were examined for parasites. Nineteen species of parasites were recovered. Hymenolepis diminuta and Nippostrongylus brasiliensis are the predominant species. The dominancy of the parasite species in the rats differed in each locality: Hymenolepis diminuta in Dato Keramat and Kuala Lumpur; Nippostrongylus brasiliensis in Sungai Besi; Gongylomena neoplasticum in Jinjang and Selayang Baru. The influences of human habitats on the parasite fauna of house rats are discussed.

Dog sera, collected from different communities throughout Selangor, Peninsular Malaysia, were investigated for the presence of antibodies to R. tsutsugamushi and R. typhi. Scrub typhus antibodies were present in animals from the rural areas only, whereas murine typhus antibodies were observed in equal numbers of dogs from both rural and metropolitan areas. Greater percentage of dogs from suburban areas had demonstrable antibody titers to murine typhus than from the urban area.
