Abstract
So-called emphysematous enteropathy was found in 11 hogs of 159, 036 inspected at the municipal abattoir in Hiroshima over a period of May, 1975, to July, 1977. Seven of the 11 hogs had been shipped from the same farm.
Lesions were found in the jejunum, ileum, and their mesentery and lymph nodes. There were differences in their severity among individuals. Histopathologically, endothelioid cells covered the inside of the lesion, which was surrounded by fibrous tissue containing many infiltrating cells. These cells consisted of histiocytes, lymphocytes, eosinophils, and rarely polynuclear giant cells.
