Parafasciolopsosis is parasitological disease caused by parasitic trematode from the family Fasciolidae. Hepatic trematode Parafasciolopsis fasciolaemorpha is a herbivore parasite and quite commonly cause invasion in elks (Alces alces). The aim of our study was to investigate the epizootic situation of Parafasciolopsis fasciolaemorpha caused invasion of elks in Latvia. The study was realized in Latvia University of Agriculture Faculty of Veterinary Medicine, Laboratory of Parasitology. During the study we collected faecal samples from seven elks of different age and gender, located in the five hectare large territory of Latvia. Five grams of faeces were examined for the presence of trematode eggs by McMasters method. Our study showed that Parafasciolopsis fasciolaemorpha were found in three samples from seven elks, with invasion extensity 42%, moderate intensity. Parasite sporocysts with redia were found in the glutinous snail (Myxas glutinosa) what shows possible intermediate host of parasite.
