【摘要】 本文报道了一群雏鸡因自然混合或单独感染伞枝犁头霉、烟曲霉和黄曲霉而引起的霉菌性肺炎病例，其中伞枝犁头霉的感染率（５７．１％）和污染率（饲料７５．４％，环境５７．９～６１．９％）均最高。伞枝犁头霉经咽喉滴注１０只雏鸡，成功地复制出与自然发病基本一致的病例。从而首次证明伞枝犁头霉是对雏鸡具有较明显致病力的条件致病菌。病雏主要表现为呼吸困难，其病理变化与哺乳动物毛霉菌病基本一致。更多还原

【Abstract】 The mycotic pneumonia of chickens mixed or individuaily infected by Absidiacorymbifera,Aspergillus fumigatus and Aspergillus flavus uas diagnosed.The infectionpercentage(57.1%)and the contamination percentage(feed 75.4%,environment 57.9～61.9%)Of A. corymbifera were higher than that of the other two. Ten chickenswere infected with A,corymbifera solution via throat dripping,and the experimentalmycotic pneumonia was uccessfully reproduced. It was consistent with the natural cases.This study suggests for the first time that A,corymbifera was a conditioned toxicfungus of significant pathogenicity to chickens;Infected chickens showed dyspnea,thepathological changes were consistent with that of mucormycosis in mammals.更多还原
