She revealed and explained the life history of the rat lungworm. Waterbuck are susceptible to ulcers, lungworm infection and kidney stones. The infected larvae reside in the lungs until the development into an adult lungworm. Liver infection is also caused by the rat lungworm "Angiostrongylus cantonensis". Cats are known to carry and spread feline lungworm in rat and snail interactions. Pastures that housed donkeys may be infected with lungworm larvae. "Parmarion martensi" is a host for the nematode "Angiostrongylus cantonensis", which causes rat lungworm disease. If infected with lungworm parasite, an anti-parasite drug must be administered. The general life cycle of a lungworm begins with an ingestion of infective larva/e. There are several different lungworm parasites that have been identified. "Dictyocaulus arnfieldi" is the lungworm of horses, and "Dictyocaulus viviparus" is the lungworm affecting ruminants. A parasitic nematode species of lungworm, "Angiostrongylus Mackerrasae", was named in her honor. Lungworm infestations can cause significant distress to the animal but are usually treatable with drugs.
