Abstract

SummaryIPNV‐carrier status was demonstrated in adult rainbow trout 15 months after experimental infection with IPNV‐subtypes Ab, Sp and He. IPN‐viruses could be detected in the peripheral blood leucocytes by co‐cultivation and by means of IFT. Internal organs of carriers were positive for virus after pretreatment with a saline‐versene‐trypsin solution only. Humoral antibodies persisted for at least 15 month in the fish.ZusammenfassungInfektiöse Pankreasnekrose: Virus‐ und Antikörpernachweis bei Regenbogenforellen (Salmo gairdneri) als IPNV‐CarrierAdulte Regenbogenforellen wiesen 15 Monate nach einer experimentellen Infektion mit den IPNV‐Subtypen Ab, Sp und He einen Carrier‐Status auf. Die Erreger konnten durch Ko‐Kultivie‐rung von Blutleukozyten isoliert und mit der indirekten IF‐Methode in den Leukozyten nachgewiesen werden. Aus den inneren Organen der Fische gelang es nur nach vorheriger Behandlung mt einer Saline‐Versene‐Trypsin‐Lösung die Viren zu isolieren. Humorale Antikörper persistierten mindestens für 15 Monate in den Fischen.
