<I>Rhizopus chinensis</I>が分離されたブロイラーの肺Phycomycosis

Abstract

A disease of high fatality had been prevalent among chicks on one broiler farm since the time of introduction into the farm. A flock of 11, 000 chicks was reduced to about 69% before it was shipped to the market. Dead birds presented edematous changes and scattered yellowish white nodules of pinhead size in the lung. A number of organisms of Rhizopus chinensis Saito were isolated from the lung in all the birds examined. Hyphae presumed to be those of this species were also observed histopathologically in the lung. A diagnosis of pulmonary phycomycosis was made in these birds.
