The histopathology in Paulicea lutkeni naturally infected with Megathylacus brooksi and Jauela glandicephalus is described. Megathylacus brooksi attaches to the epithelium of the anterior intestine by means of suckers, resulting in damage to the epithelium, haemorrhages and lymphocyte infiltration. Jauela glandicephalus penetrates through all layers of the intestine. This penetration elicits an intense host‐response resulting in the hyperplasy of connective tissue and formation of a nodule surrounding the scolex of the parasite. Lymphocyte infiltration was observed. Concurrent infections were found in some specimens.
