作者曾报道,从泰国一名患者体内分离出一株耐氯霉素(CP)、四环素(TC)、链霉素(SM)、卡那霉素(KM)、氨苄青霉素(ABPC)、TMP和0/129的副溶血弧菌ST550。本文证实此多重耐药株的接合型R质粒。接合转移试验中用副溶血弧菌ST550株作为供体,结果以10~(-3)、10~(-4)、10~(-5)～10~(-7)的频率分别获得大肠杆菌、副溶血弧菌、不凝集弧菌和溶藻弧菌的转移接合子,接合子的药物敏感性和抵抗力形式与供体相似。ST550株质粒的转移率显著受供体生长阶段的影
The authors have reported that a chloramphenicol (CP), tetracycline (TC), streptomycin (SM), kanamycin (KM), ampicillin (ABPC) 0/129 Vibrio parahaemolyticus ST550. This article demonstrates the conjugate R plasmid of this multidrug-resistant strain. In the conjugate transfer test, Vibrio parahaemolyticus strain ST550 was used as the donor, and E. coli strains were obtained at frequencies of 10 -3, 10 -4, 10 -5, and 10 -7, respectively , Vibrio parahaemolyticus, Vibrio agglutinans, and Vibrio alginolyticus, and the binders have similar drug sensitivities and resistances to donors. The transfer rate of ST550 plasmids was significantly affected by the donor growth phase
