Abstract

Mortality of farmed coho salmon Oncorhynchus kisutch due to erythrocytic inclusion body syndrome (EIBS) has been posing severe economic losses in Japan since 1986. ​The etiologic agent of EIBS was reported to be piscine orthoreovirus 2 (PRV-2). ​We detected PRV-2 in the ovarian fluid samples of 10% of EIBS-experienced spawners (n = 30) by RT-PCR. ​When each of 30 individual ovarian fluid samples was inoculated into a naïve coho salmon, 37% of the blood samples from the fish tested positive for PRV-2 at 20 days post injection. ​These observations suggest that the ovarian fluid of EIBS-experienced fish can be contaminated with the infective viral particles of PRV-2.
