PY - 2021 T2 - Current Medical Diagnosis & Treatment 2021 AB - A number of species of Gnathostoma, which are parasitic nematodes of carnivores, can occasionally infect humans. Most cases have been seen in Southeast Asia, but the disease has also been described in many other areas. Eggs shed in the feces of mammals are ingested by marine crustaceans, which are then ingested by fish, frogs, snakes, or mammals. Larvae then encyst in muscles. Human infection follows eating undercooked fish, shellfish, chicken, or pork and can also be transmitted by ingesting copepods in contaminated water. After ingestion, larvae cannot complete development in humans, but rather migrate through tissues (eFigure 35–43).
