Type species of the genus: Culcullanus ascaroides Goeze, 1782
Male:
Female:
Predominantly parasites of freshwater fish but, to a lesser extent, marine fish and aquatic reptiles including crocodilians.
Freshwater and marine fish, aquatic reptiles.
Described from Rachycentron canadum (Linnaeus), cobia (Rachycentridae). Chaetodiptems faber (Broussonet), Atlantic spadefish (Ephippidae); Ophicthus sp.
Gastro-intestinal parasites.
Reduced productivity in freshwater fish farms. Very occasional infection of humans through consumption of raw fish.
Host response to species of Goezia varies among hosts.
In some cases, the nematode penetrates into the muscular tissues and a vascularized, dense, collagenous capsule develops, often with a chronic inflammatory response extending about 1 mm from the capsule. Mucosa still remains in contact with the nematode but iss inflamed and laden with bacteria, and sloughing. The exposed wall lining the capsule had plications depicting a mirror image of the external cuticular rings which had fit there before the tissue was fixed (Fig. 50). Some regions of the wall become heavily infiltrated by both coccoid and rod-shaped bacteria (Deardorff and Overstreet, 1980).
