| dc.description.abstract | This study was conducted to determine the types of rats and their ectoparasites,
the relative density (trap success) of rats, the specific flea index (SFI), the prevalence,
and the intensity of ectoparasite infestation in the densely populated residential area
of Mesjid Village, Medan Kota District, Medan City, North Sumatra. The study was
conducted in August 2025 at three locations with different environmental
characteristics, namely flood-prone areas, non-flood-prone areas with accumulated
waste, and shopping areas. The method used was a cross-sectional approach by
installing traps in 10 houses per location. A total of 20 single live traps were set up,
one trap outside the house and one trap outside the house, for 4 consecutive days. The
captured rats were identified by species and ectoparasites at the Medan Community
Laboratory Center (BLKM). The results showed that the rat species caught were
Rattus novergicus, Rattus tanezumi, and Suncus murinus (Insectivora). The highest
relative density (trap success) was found in environments 2 and 3, with values of
11.25% each. Three types of ectoparasites were found on the captured rats, namely
Laelaps sp. mites, Xenopsylla cheopis fleas, and Dermacentor sp. ticks. The highest
prevalence was found in Laelaps sp. in environments 2 and 4 on R. tanezumi, each
with a value of 100%. The highest intensity was found in environment 3, as well as.
The relationship between the specific flea index (IPK) of X. cheopis and the prevalence
and intensity of X. cheopis is inversely proportional. | en_US |
