Atypical Interstitial Pneumonia in Cattle Fed Moldy Sweet Potatoes

Abstract

SUMMARY Sixty-nine adult cattle in a herd of 275 died after being fed moldy cull sweet potato ( Ipomoea batatas ) roots. Clinical signs and necropsy findings were characteristic of atypical interstitial pneumonia. The disease was experimentally reproduced in cattle by oral administration of homogenized sweet potato cultures infested with Fusarium solani ( F. javanicum ) isolated from the moldy sweet potatoes fed the herd.
