A postmortem survey on ten rats (Rattus spp.) caught in the Veterinary Research Institute (VRI) was done to evaluate the parasite, viral and bacterial status. The rats were trapped in the laboratory animal facilities in VRI. The results indicated that seven rats harboured mites (Demodex sp.) from skin samples. Parasite eggs such as strongyle and Strongyloides sp. were also recovered from the intestines of four rats. Bacterial species isolated from the organs include Mycoplasma arthritidis, Corynebacterium sp., Staphylococcus epidermidis, Escherichia coli and Enterococcus sp. Serological test detected the presence of antibody against Leptospira canicola, Leptospira celledoni and Leptospira pyrogenes. Many of these organisms are zoonotic especially Leptospirosis which can cause severe disease in humans. No pathogenic viruses were recovered from the rats. Control and eradication of pests like rats is essential to safeguard the health of humans.
