| Abstract: | Abstract. An indirect fluorescent antibody (IFA) test was developed to detect viral antigen in tissue sections prepared from rainbow trout experimentally inoculated with infectious pancreatic necrosis virus (IPNV). Specific fluorescence was present in the pancreatic acinar tissue and occurred as brilliant fluorescence throughout the mesentery surrounding the pyloric caeca and intestines. In addition, multiple foci of fluorescent cells were seen occasionally in the kidneys and liver of infected fry. Fluorescence was not observed in tissues other than the pancreas, kidneys, and liver. The IFA test was found to be quite specific and offers a rapid means of diagnosing IPN during acute outbreaks. |
