First identification of the nematodes Setaria tundra in roe deer in Croatia by molecular method

The genus Setaria includes 43 species of parasites that infest the peritoneal cavity of ungulates. Vectors such as mosquitoes (Culicidae spp.) and flies (Haematobia spp.), transmit the disease through blood infected with microfilaries. Adult parasites are mostly non- pathogenic, and cause mild fibrinous peritonitis. However, the outbreak of epidemic peritonitis in reindeer from Finland emphasizes the necessity to monitor the occurrence of the species Setaria tundra in wild ungulates. In Croatia, the last published data about the genus Setaria date back to 1958, when Setaria labiatopapillosa was identified in roe deer (Capreolus capreolus), so the aim of this study was to analyze the presence of parasites from the genus Setaria in roe deer in Croatia today. We conducted necropsies on 45 roe deer killed during regular game management activities, and Setaria were found in the abdominal cavity of 11 animals (22.2%). For molecular identification part of the cox1 gene was multiplied by PCR and sequenced. The sequences found in this research were identical to Setaria tundra sequences deposited in the Gene Bank, so this is the first confirmation of this parasite in Croatia.
