What's the difference between lungworm and lungwort?
Lungworm
Definition:
(n.) Any one of several species of parasitic nematoid worms which infest the lungs and air passages of cattle, sheep, and other animals, often proving fatal. The lungworm of cattle (Strongylus micrurus) and that of sheep (S. filaria) are the best known.
Example Sentences:

(4) The calves given ivermectin excreted no lungworm larvae and remained free of clinical parasitism throughout the trial.

(9) Features of the epizootic included (1) infection of all herds within one geographic location, during a short period; (2) no obvious introduction of virus from the outside in most herds; (3) epizootics mainly in herds with serologic history of infection; (4) no evidence that lungworms were involved; and (5) little clinical disease associated with infection.
(10) Similar signs were also observed after infection with bovine respiratory syncytial virus, but the signs were more acute and resolved more rapidly than in animals infected with lungworm larvae.

Lungwort
Definition:
(n.) An herb of the genus Pulmonaria (P. officinalis), of Europe; -- so called because the spotted appearance of the leaves resembles that of a diseased lung.
(n.) Any plant of the genus Mertensia (esp. M. Virginica and M. Sibirica) plants nearly related to Pulmonaria. The American lungwort is Mertensia Virginica, Virginia cowslip.
