| Summary: | The objectives of this study were to determine species of rodents and identify endo
and ectoparasites of the rodents from four selected student’s Colleges in Universiti
Putra Malaysia (UPM). Rodents were captured using a wire live trapped, humanely
euthanised and identified using a key for morphological identification of rodents.
Ectoparasites were collected by combing the fur of the rodents on white plain sheet
paper. The ectoparasites were washed and mounted with Hoyer’s media on a glass
slide for identification. After dissection of the rodents, the blood, tissues, and stool
samples were collected and analysed based on standard parasitological laboratory
procedures. A total of 89 wild rats that comprised of three species, Rattus rattus
diardii, Rattus norvegicus, and Rattus tiomanicus were identified. A total of twelve
species (Hymenolepis nana, Hymenolepis diminuta, Aspiculuris tetraptera, Syphacia
spp., Strongyloides ratti, Trichuris spp., Heterakis spumosa, Nippostrongylus
brassielensis, Giardia spp., Entamoeba histolytica/Entamoeba dispar,
Cryptosporidium spp. and Moniliformis moniliformis) of intestinal parasites were
identified from the captured rodents. The study reveals that 18.7 % of the rodent
examined has at least one species intestinal parasites. Forty-three percent of the
rodents were found to be infested with ectoparasites. The ectoparasites species
identified include: Laelaps echidnina, Laelaps nuttalli, Ornithonyssus bacoti, Ixodes
granulatus, Haemaphysalis spp., Polyplax spinulosa, Hoplopleura pacifica and
Xenopsylla cheopis. Trypanosoma spp. was the only blood parasite identified in the
present study with low prevalence rate (3.3%). Furthermore, histopathological
examination of the tissue sections of brain, liver, lungs, and muscles reveals the
presence of parasites that include: Taenia taeniaeformis Strobilocerci (in the liver),
Toxoplasma gondii (in the brain), Angiostrongylus cantonensis (in the lungs),
Sarcocystis spp. (in the muscle) and Capillaria hepatica (in the liver). The finding of
this study showed that wild rats captured from the study area are infected with different
parasites of zoonotic importance. This suggests a potential risk of rodent-borne
zoonotic disease transmission to humans. Awareness of prevention and control of rodent-borne diseases should also be introduced to educate the students on the
importance of zoonotic diseases associated with rodents. |
