| Abstract: | BKD発生歴のある孵化場の健常サクラマス幼魚の50%以上が抗R.s.抗体を保有し, その一部からIFATでR.s.が検出された。一方, BKD発生歴の無い孵化場の幼魚は, 全て抗R.s.抗体陰性であった。また, 河川遡上した親魚から抗R.s.抗体は検出されなかったが, BKD発生歴のある孵化場で2ヶ月間催熟蓄養した親魚の抗R.s.抗体陽性率は33%で, その一部からR.s.が検出された。従って, BKD発生歴のある孵化場内でのR.s.感染環に幼魚と親魚間の水平感染が関与していると考えられる。 | | Detection of antibodies against Renibacterium salmoninarum (R.s.), a causative agent of bacterial kidney disease (BKD), was conducted among apparently healthy fingerlings and broodstock of masu salmon Oncorhynchus masou. Antibodies against R.s. were detected from ≧ 50% of fingerlings in the hatcheries with BKD-histories and R.s. antigens were detected in some of antibody-positive fish, but not from those in the hatchery without a BKD-history. Although returning broodstock examined within two weeks after introduced into the hatchery showed all negative for anti-R.s. antibodies, 33% of those in the hatchery with BKD-histories became positive after two months of rearing for sexually maturation. Monitoring specific antibodies suggests that R.s. infection-cycle is completed between fingerlings and broodstock in hatcheries having BKD-histories. |
