Experimental infection of cats with the liver fluke Platynosomum concinnum,.
The severity of Platynosomum concinnum infection in cats experimentally infected with 125 flukes (small dose) and 1,000 flukes (large dose) was determined by monitoring clinical signs and hematologic, serum biochemical, and pathologic changes during the infection. All cats (8/8) with a small fluke burden and 3 of 8 cats with a large burden remained clinically asymptomatic, whereas 60% of the cats given large doses had mild signs of inappetence and lethargy. Eosinophilia, peaking 4 to 5 months after infection, was present in all parasitized cats. During the early stages of platynosomiasis, a transient but substantial increase in aspartate aminotransferase and alanine aminotransferase activities was observed in cats given small and large doses. These observations agreed with gross and histopathologic observations, which included enlargement of the gallbladder and biliary ducts, with leukocyte infiltration, adenomatous hyperplasia, and fibrosis of the ductal areas.
