Conjugative transfer

Effects of carbon sources on conjugative transfer rate of bacterial plasmid pea9 ∷ km in soil

营养物质对细菌质粒pEA9∷Km在土壤中接合转移频率的影响

As the donor and recipient in conjugation mixture decreased , the concentration of nano-Al2O3 that can stimulate RP4 conjugative transfer maximumly reduces too . 2 .

随着接合菌液浓度降低，能最大地促进RP4接合转移的纳米Al2O3的浓度也降低。

These data showed that it might be a common phenomenon that nano-materials could promote the conjugative transfer of resistance genes .

这些数据说明，纳米材料对接合质粒介导的耐药基因转移的促进作用可能是一个普遍现象。

Conjugative transfer of self-transmissible plasmid in environment plays a crucial role in the dissemination of antibiotic resistance genes among bacterial populations .

可自主转移质粒在环境中的接合转移对细菌耐药性的传播起着重要作用。

Identifying with five kinds of antibiotic , we have obtained 271 strains of the drug resistant bacteria , detecting with the conjugative transfer experiment , we have got 41 strains of the drug resistant transferable bacteria .

用5种抗生素进行抗性测定后，分离到271株抗性菌株。

Methods Antibiotic susceptibility was tested by the disk diffusion to screen out the strains that produced the ESBLs ; conjugative transfer test , plasmid profile , PCR and DNA sequencing were used to detect the phenotype or genotype of STEC .

方法采用纸片琼脂扩散法筛选36株产志贺毒素大肠埃希菌产ESBLs菌株，接合传递实验、质粒谱分析、PCR检测耐药基因和DNA序列分析产ESBLs菌株的表型和基因型。

Most extant bacteria and some ancient bacterial populations encode ( d ) a conjugative system . There are several conjugative transfer units , including self-transmissible plasmids , mobilizable plasmids , transposons , and integrated conjugative units .

大多数细菌和一些古细菌类群可以编码接合系统，存在多种接合转移单元，包括自转移接合质粒，诱动质粒，接合转座子以及一体化的接合单元。
