The larvae penetrate the animal s intestines and travel to the lungs where they develop into adult worms. Other lungworms do not need a snail or slug host. The larvae develop into the infective stage on plants that are then eaten by the herbivore. Lungworms are found in bison, muskox, caribou, reindeer, and Dall sheep. In Alaska a number of different lungworms occur commonly in caribou and muskox.
Animals often appear healthy.
Animals with severe infections may cough and have difficulty breathing, especially after running. They may be generally weak and thin and have a harsh, dull hair coat. You cannot become infected by lungworms. Meat from infected animals is suitable for human consumption. All Rights Reserved.
