| Abstract;During the period from June to September 2004, 700 of 867 nursing piglets experienced yellowish diarrhea with a watery consistency on a swine farm in Iwate Prefecture. Clinical signs of the disease were found among five- to nine-day-old piglets. Seventy piglets died or were eradicated for retarded growth. One affected and two convalescent piglets were examined pathologically and pathogenetically. The principal lesions were present in the jejunum and ileum. Fibrinonecrotic enteritis with Isospora suis in various stages of development was observed in the affected piglet, and a pronounced atrophy of the intestinal villi was found in the convalescent piglets. Oocysts of the organism were obtained from the rectal contents of the affected piglets, but not from those of the sows. There was no evidence to suggest that other enteropathogens had been associated with the disease. These results indicate that this outbreak would have been caused by an I. suis infection. Since the occurrence was markedly diminished after the farrowing crates and concrete floor were disinfected with orthodichlorobenzene and steam, the sources of the infection may have been present under the farrowing environment.
