Trematodes of the Small Intestine

 

This is by far the largest group of trematodes found in the cat. Trematodes differ from other helminths in that they are often less discriminating in their requirements for a final host. For this reason, cats can harbor a large number of trematodes that they share with other animals that might eat the same intermediate hosts containing the arrested metacercarial stage. For example, if a trematode uses a fish as a second intermediate host, it might grow to adulthood in a cat, a dog, a piscivorous bird, an otter, or a raccoon. Thus, it is sometimes difficult to be certain whether the "true” final host is the cat or some other animal. Also, there are reports of worms being recovered on single or only a few occasions because cats are becoming infected when they accidentally ingest a metacercarial-containing meal meant for another host.
