【摘要】 分别采集马属动物 (马、骡 )、反刍动物 (牛、羊 )的新鲜粪便 ,进行捕食线虫性真菌的分离培养 ,调查了捕食线虫性真菌在家畜粪便中的分布情况 ;并对分离到的捕食线虫性真菌做了详细的形态学观察 ,进行种属鉴定。结果表明 :从上述家畜新鲜粪便中均分离出捕食线虫性真菌——梨形指环菌 (Dactylaria pyriformis) ,但该菌株在不同家畜粪便中的分布情况不同 ,马属动物粪便的分出率为 10 .0 % (骡粪 :13 .3 % ,马粪 :6.7% ) ;反刍动物粪便的分出率为 2 6.7% (牛粪 :2 3 .3 % ,羊粪 :3 0 .0 % ) ;总分出率为 18.3 %。更多还原

【Abstract】 Fresh livestock(Horses, Mules, Cattle, Sheep) faeces were collected. From them, Nematode trapping fungi were isolated and cultivated for investigating the distribution situation. Also, the isolated nematode trapping fungi were observed in morphology and differentiated. The result indicated the nematode trapping funus isolated from livestock faeces above was Dactylaria pyriformis and the isolated rate was averagely 18.3%. The rates was various in different livestock faeces. They were respectively 10.0% in equine (Mules faeces: 13.3%, Horses faeces: 6.7%) and 26.7% in ruminants (Cattle faeces: 23.3%, Sheep faeces:30.0%).更多还原
