Fauna Binatang Mengerat dan Parasitnya di Beberapa Daerah Transmigrasi di Indonesia, Serta Hubungannya dengan Penyakit Rickettsiosis yang Ditularkan oleh Vektor

Abstract

Surveys on small mammal parasites conducted in several transmigration schemes in South Sulawesi, Central Sulawesi and East Kalimantan, Indonesia revealed 10 species of murid rodents. Rattus exulans and some forest rats were predominant in newly opened schemes, whereas Rattus rattus was predomi­nant in older schemes. Six species of rats collected in all areas surveyed were found infested with a chigger species Lepto trombodium (L.) deliensis, a known vector of scrub typhus. Xenopsylla cheopis, a flea vector of murine typhus, was not found during the survey. Serological studies revealed that 22.7% of the rats collected in an area planned for a transmigration scheme in Central Sulawesi, have antibodies against scrub typhus and 12,5% against murine typhus. The risk of transmission of scrub typhus and murine typhus to human is discussed
