Sažetak
Detection of parasites and pathogens of molluscs allows the management of natural stocks and disease control in native and cultured species. In this study, we investigated digestive gland cryosection of the Mediterranean mussel Mytilus galloprovincialis Lamarck, 1819 sampled at two locations (St. Andrew and ACI Rovinj) in the northern Adriatic Sea across annual cycle. The protozoan of the genus Nematopsis Schneider, 1892 (Apicomplexa, Gregarina) have been found for the first time in cryosections of mussel from both sampling stations. One to three oocyst of Nematopsis sp. were detected in most cryosections located within phagocyte in connective tissue between digestive tubules of mussel digestive gland. In some cryosections, five to eight oocyst were observed. The prevalence of Nematopsis sp. ranged from 20% to 100% in the one-year study. Intensity of infection was variable, with < 30 oocyst per section in most of the cases (maximum 110 oocysts/mussel). We observed the parasite infection in relation to habitat, time of sampling and environmental factors.
