In managing the koi herpesvirus (KHV) outbreaks as a routine national program in Indonesia, testingbased on biotechnology, such as immunopathologic immunohistochemical approach(es) using antibodythat is safe, rapid and accurate need to be applied. This will hopely assist the Government of Indonesianin improving and enhancing the sustainability of national animal proteins program. The present studywas aimed to develop and apply the immunopathologic immunohistochemistry of streptavidin biotin (IHCSB) for detection of KHV in the apparently normal carps. The gills from 48 common carps (Cyprinuscarpio) that appear to be healthy were prepared for DNA-based KHV by IHC SB. Common carps werecollected from fish farms which had an outbreak of KHV in 2008-2009 in Yogyakarta. All fish werenecropsied. The gills were processed histopathologically and then stained for IHC SB with monoclonalantibody anti-KHV. We demonstrated that all of the fish gills were positive for KHV antigen. Thus, it isconcluded that method is useful and consistent, very sensitive and rapid, and is a reliable method to beapplied for field condition to detect antigen KHV in the gills of normal, healthy looking carps. In addition,and more importantly, the fish can act as a source of KHV (carriers for KHV) and may result in the spreadof diseases among susceptible fish.
