Pneumoconiosis (redirected from pneumoconiotic)

pneumoconiosis /pneu·mo·co·ni·o·sis/ (-ko?ne-o´sis) deposition of large amounts of dust or other particulate matter in the lungs, causing a tissue reaction, usually in workers in certain occupations and in residents of areas with excessive particulates in the air; there are many types, including anthracosis, asbestosis, bituminosis, and silicosis.

pneumoconiosis (noo´mōkō´nēō´sis),

pneumoconiosis

any of a group of lung diseases resulting from inhalation of particles of industrial substances, such as the dust of iron ore or coal, and permanent deposition of substantial amounts of such particles in the lungs.

The disease is rare in animals unless there is an unusual exposure to a dusty environment. Horses are the ones most commonly exposed, usually in a mining operation (pit ponies). Exercise intolerance and chronic cough are the cardinal signs.
