Abstract
A one-year-old male Chippiparai dog was submi ed for necropsy to the Department of Veterinary pathology, Veterinary
College and Research institute, Orathanadu. During necropsy, the gross lesions were observed and required tissue samples
were collected for histopathology. Fluke and worms were collected for parasitological identifi cation. Grossly, right lung showed
a grey patch and on cut section showed the presence of cavity containing two conical fl ukes. Oesophageal lumen contained
spiral worm near the nodule and on section of nodule contained blood mixed exudate. Based on the morphology, the fl uke was
identifi ed as Paragonimus sp and worm was identifi ed as Spirocerca lupi. Histopathologically, lung revealed the presence of eggs
of Paragonimus sp, chronic bronchitis, immature eggs, mature eggs with miracidium, and giant cell. Based on the gross lesions,
morphology and histopathology, the very rare case of combined infection of pulmonary paragonimiasis and spirocercosis in a
chippiparai dog is documented.
