Protozoan parasite species of the genus Perkinsus have been known to infect various venerid clams and induce pathological functions. In this study, polymerase chain reaction (PCR) analysis using species-specific primers was conducted to investigate Perkinsus olseni and Perkinsus honshuensis infections in Ruditapes philippinarum and Ruditapes variegatus collected from the coast of Dongil-ri harbor and Hamo beach, Daejeong, Jeju, Korea in the winter of 2020. Based on the results of an investigation on the infection of the two parasite species in the two host species, it was confirmed that only R. variegatus specimens collected from the Hamo beach were infected with P. olseni. Previous studies have reported R. variegatus as a host for P. honshuensis, but based on the findings of this study, it is suggested that this clam species could be infected by not only P. honshuensis but also by P. olseni.
