洋葱伯克氏菌(Burkholderiacepacia,Bc)和铜绿假单胞菌(Pseudomonas aeruginosa,Pa)既是农业上的生防菌又是医院的人体条件致病菌,了解它们的特征及在水稻上的分布情况是有效管理和利用这类原核生物的关键。在过去的9年中,利用常规细菌学、致病性测定、Biolog和脂肪酸分析(FAME)对采自平原、丘陵和山区稻区的631份稻谷样本和117份稻株样本进行了两类人体条件致病细菌的鉴定和检测研究。Bc菌和Pa菌可通过培养性状和常规细菌学方法作初步鉴别,Biolog和FAME能把它们鉴定到种,但Bc菌的基因型难以区分。Bc菌和Pa菌主要存在于水稻的根部;Bc菌和Pa菌在浙江的平原稻区分布最广,分别达6.1%和16.1%;在山区稻区最低,分别为1.0%和7.8%。
Burkholderiacepacia (Bc) and Pseudomonas aeruginosa (Pa) are both pathogenic bacteria in agriculture and pathogenic bacteria in hospitals, and their characteristics and their distribution on rice It is the key to effective management and utilization of these prokaryotes. Over the past nine years, two types of human subjects have been subjected to conventional bacteriological, pathogenicity assays, Biolog and fatty acid analysis (FAME) on 631 rice samples and 117 rice samples from paddy fields in the plains, hills and mountains Identification and detection of conditional pathogenic bacteria. Bc bacteria and Pa bacteria can be initially identified by culture traits and conventional bacteriological methods. Biolog and FAME can identify them, but the genotypes of Bc bacteria are indistinguishable. Bc bacteria and Pa bacteria were mainly found in the roots of rice. Bc bacteria and Pa bacteria were the most widely distributed in plain rice in Zhejiang Province, accounting for 6.1% and 16.1% of the total, respectively; the lowest in the rice growing areas was 1.0% and 7.8% respectively.
