Plain-English summary
A domestic cat in Sri Lanka was brought to the vet with liver and bile duct problems, showing signs of illness related to a parasitic infection. Tests, including blood work and an ultrasound, revealed a large number of parasite eggs in the bile. The vet identified the infection as being caused by a type of liver fluke called Platynosomum, which had not been previously reported in the region. This case highlights the need for more research on this parasite in local cat populations and suggests that it should be considered when diagnosing liver diseases in cats.

Abstract
Platynosomum is a digenean trematode causing hepatobiliary disease in cats in tropical and subtropical regions. The presence of Platynosomum species in Sri Lanka has not been previously reported or investigated. In the current study, we report a clinical case of a cat suffering from hepatic and biliary complications. Fine-needle aspiration of the biliary extract revealed a large number of parasite eggs, and the morphological and molecular identification of eggs was carried out. Molecular phylogenetics was performed using the nuclear ribosomal Internal Transcribed Spacer 2 (ITS2) and a portion of a mitochondrially encoded gene; Cytochrome C Oxidase subunit 1 (COX1). Through a combination of history, clinical signs, blood reports, ultrasound scanning, light microscopy of eggs from biliary aspirate and molecular studies, the disease was confirmed as parasitism caused by a Platynosomum like species. The Platynosomum species in Sri Lanka is phylogenetically related to Platynosomum illiciens reported from Costa Rica, Central America. This case emphasizes the importance of future studies in Sri Lanka regarding the prevalence and distribution of Platynosomum among cat populations. Further, the inclusion of feline platynosomiasis in the differential diagnoses list for hepatobiliary diseases is required.
