초록
Shortfin eel (Anguilla bicolor pacifica) is a species of commercial importance and itsproduction is greatly affected due to the infection by Heterosporis anguillarum. In this study, weevaluated the effect of H. anguillarum infection on the growth of Shortfin eel. A disease that trunkmuscle of cultured shortfin eel, Anguilla bicolor pacifica, were irregular and resulted in death,breakout of the commercial eel culture farm. We observed that the trunk muscle of infected eels were irregular and represented white or yellowishexternally. Histopathologically, a great numbers of large or small spores and sporophorocystswere also observed in degenerated muscle layer. The cloning of specific gene of H. anguillarum, encoding small subunit ribosomal RNA (SSU-rRNA)was amplified by the polymerase chain reaction(PCR) from the muscle lesion of diseased eel. Thesize of clone gene is well matched with the size of small subunit ribosomal RNA of H. anguillarumand thus confirming the infection by H. anguillarum.
