Sažetak
Consumption of raw or thermally inadequately treated fishery products represents a public health risk, bearing the possibility of propagation of alive Anisakis larvae, causative agent of zoonotic disease ‘anisakidosis’ or ‘anisakiasis‘. We investigated population dynamic of Anisakis spp. in commercially important fish ; anchovy (Engraulis encrasicolus), sardine (Sardina pilchardus), European hake (Merluccius merluccius), whiting (Merlangius merlangus), chub mackerel (Scomber japonicus) and Atlantic bluefin tuna (Thunnus thynnus) captured in the main Adriatic Sea fishing ground. We observed a significant difference in the number of parasite larvae (1-32) in individual hosts and between species, with most fish showing high or very high values of Anisakis population indices. Phylogenetic analysis confirmed that commercial fish in the Adriatic Sea are parasitized by Anisakis pegreffii (95.95%) and A. simplex sensu stricto (s. s.) (4.05%). Genetic structure of A. pegreffii in demersal, pelagic and top predator hosts was unstructured and the highest frequency of haplotypes sharing (N=10) was between demersal and pelagic fish.
