Sažetak
A high anti-Anisakis IgE seroprevalence was detected previously in the healthy Croatian southern islands’ population. In order to understand the potential source of antigen to inhabitants, we investigated a random sample of most frequent fish species landed at fish market in the Island of Korčula, area where the the highest seroprevalence was observed. Additionally, we sampled damselfish and picarel, fish that are traditionally consumed freshly marinated only in this region. Statistical and genetic analyses were performed by grouping Anisakis-infected fish according to their feeding habits ; large, smaller and benthopelagic pelagic predatory fish, and small bottom-feeding fish, respectively. No statistically significant difference was detected among each group pair in terms of prevalence, abundance or intensity of infection. The highest prevalence was recorded in dolphinfish and little tunny (100% (95% CI 36.85-100.00) and 100% (95% CI 47.29-100.00), respectively). Anisakidae community from this area consisted of Anisakis pegreffii (96.4%), A. simplex sensu stricto (3.17%), A. typica (0.19%) and A. zyphidarum (0.19%) inferred by a single mitochondrial DNA locus cytochrome oxidase (cox2). In respect to the potential source of anisakid antigen for the high anti- Anisakis IgE seropositive population of Island of Korčula, the incidence of larvae in the European hake fillets (mean intensity 2.22 (bootstrap 95% CI 1.56-3.56)) is indicative as a factor in such epidemiology. This work was fully supported by Croatian Science Foundation (Hrvatska zaklada za znanost, HRZZ), grant number 5576, AnGEl: Anisakis spp.: genomic epidemiology.
