The study objectives were to describe pathologic changes associated with developing actinospores within D. digitata from a commercial catfish pond during an active PGD outbreak. Specific in situ hybridization probes identified H. ictaluri, Henneguya exilis, and Raabeia-type TGR 2014 actinospore development in pure infections associated with intestinal epithelial hypertrophy, hyperplasia, and vacuolation.
