PCR testing for diagnosis of ichthyophonus hoferi:Comment on hamazaki et al. (2013)

Abstract

It is our opinion that Hamazaki et al.(2013; Dis Aquat Org 105:21-25)overstate the usefulness of PCR as a field diagnostic technique and underestimate the accuracy and utility of in vitro explant culture.In order for field diagnostic studies to be meaningful they should accurately and dependably identify the infected individuals within a population,both subclinical and clinical cases.Although explant culture,like most techniques,can miss some infected individuals,́false positiveś are impossible,unlike for cPCR based methodologies. © Inter-Research 2013.
