Phylogeny of the Koi herpesvirus and development of a vaccine against the Koi herpesvirus disease

The aim of this presented dissertation was a stable, live attenuated and protective KHV usable as vaccine. Moreover this vaccine should by cost effective and easy to apply. Differentiation of infected and vaccinated animals was preferred by genetic and / or serological means. After achieving an attenuated virus, whole genome sequencing should be done to examine the genetic of the vaccine as one feature of biosafety. Besides biosafety additional knowledge on the virulence of Alloherpesviruses, especially of KHV was anticipated. Additionally the diagnostics of KHV and KHVD should be improved to increase reliability and to gain more insights into the relationship of different KHVs and hopefully to detect the source of an outbreak.
