Abstract
Aberrant Ascaris suum Nematode Infection in Cattle, Missouri, USA.
Highlights
In September 2010, a 1.5-year-old heifer from a farm was brought to Veterinary Medical Diagnostic Laboratory (VMDL), University of Missouri (Columbia, MO, USA), for postmortem examination
Interstitial pneumonia was diagnosed on the basis of gross appearance, and viral pneumonia or acute bovine pulmonary emphysema and edema, especially that caused by toxic Perilla mint (Peri indicutescens), was suspected
Cases of aberrant infection of A. suum nematodes in cattle are rare; no infections have been reported in North America since the 1960s [5]
Summary
In September 2010, a 1.5-year-old heifer from a farm was brought to Veterinary Medical Diagnostic Laboratory (VMDL), University of Missouri (Columbia, MO, USA), for postmortem examination. The farm contained 15 heifers, all of which had shown similar clinical signs for 2–3 weeks. Microscopic examination showed diffuse, severe, fibrinous, eosinophilic and histiocytic interstitial pneumonia and multiple nematode larvae in bronchi and alveolar sacs (Figure). To the Editor: Ascarididae is a family of parasitic nematodes, commonly known as intestinal roundworms, that affects humans and various animals, including pigs, dogs, cats, horses, raccoons, and marine mammals.
