Abstract

Posterior kidney imprints stained by Leishman/Giemsa or squash preparations viewed by phase contrast microscopy have been used extensively during the past year during our investigations of the PKD episodes at the Hagerman, IDFG facility. We have found them to be more definitive than stained tissue sections and far less expensive and time-consuming to execute.
Since there have been some allegations that the organism causing PKD may be far more common in nature than has been documented, we suggest that fish from water courses into which intensive finfish culture operations discharge be examined for the presence of the PKD-causing organism during the months of July and August.
