Koi herpesz betegség - Kopoltyúnekrózis

Translated title of the contribution: Koi herpes disease - Gillnecrosis

Research output: Contribution to journalArticle

Abstract

The author compared two major diseases of the common carp (Cyprinus carpio L.y, koi herpes disease and gill necrosis. Koi herpes disease was first reported from Israel (1999), causing high mortalities over 80%; gill necrosis was first found in the European part of the Soviet Union in the 50's of the past century and caused high losses, up to 60 to 80% in cultured common carp in the 70's and 80's in Eastern and Central European countries. The major symptoms of both diseases were severe necrotic changes in the gills of the carp. The agent of koi herpes disease (cyprinid herpes virus or CyHV-3) was detected in 2000. Most of the scientists stated that gill necrosis was caused by ammonia intoxication. In those days the level of fish virology was very low, and efforts for isolate a virus were unsuccessful. At the end of the 80's the disease ceased and became very sporadic. The author of this paper thinks that koi herpes disease corresponds to gill necrosis and appeared in Israel after the undetected virus of the gill necrosis had been introduced from Europe by imported carp. In Central European countries CyHV-3 was isolated in 2005 in Poland (1), in 2009 in the Czech Republic (12) and in 2012 in Hungary (personal communication). The author supposes that in these countries where the disease has already existed for several decades no fatal mortalities will appear.
