Extract
The equine lungworm was first reorded in a donkey (Equus asinus) and named Strongylus arnfieldi by Cobbold Citation(1884). Later it was recognized in the horse by Railliet and placed in the genus Dictyocaulus by Railliet and Henry in 1907. Numerous reports describe its cosmapolitan distribution although the cases de- scribed below appear to be the first published records of it from New Zealand, apart from a Department of Agriculture Report (Anon., Citation1966).
