摘　　要：对来源于不同环境的41株洋葱伯克氏菌进行了毒力基因检测及致病性研究.4个毒力基因(BCESM,cbl A,cepR和cep I)被从数量不等的菌株中扩增到,从而认定了10个风险性较高的菌株;通过苜蓿和生菜模型致病性测定,发现不同来源的很多菌株表现出对苜蓿和生菜不同程度的致病力.所研究的洋葱伯克氏菌株大部分被认定对人体健康存在风险.The risks of forty-one Burkholderia cepacia （ Bcc ） strains isolated from different environmental sources had been assessed through detection of virulence genes and research on pathogenic model. There were four virulence genes （BCESM , cblA, cep R and cepI） been detected from a variable number of strains, 10 of them were identified as high-risk strains. In addition, most of strains of different sources showed different degrees of virulence on alfalfa and lettuce. Therefore, most Bcc strains were considered as risky strains to human health.
