Tissue Response of Fish to Invasion by Larval Pseudoterranova decipiens (Nematoda; Ascaridoidea)
The histopathology of Pseudoterranova decipiens (L 3 ) in experimentally infected rainbow trout (Oncorhynchus mykiss) and naturally infected Atlantic cod (Gadus morhua) was similar. The chronic granulomatous inflammatory reaction included polymorphonuclear neutrophils, macrophages, lymphocytes, epit...
