Abstract

In a series of Pseudomonas aeruginosa strains resistant to gentamicin, tobramycin, amikacin and/or netilmicin (Knothe and Krčméry, 1979), wild-type phage lysates could be prepared and two of them were studied more in detail. Both lysates were shown to mediate transfer of gentamicin, amikacin and carbenicillin resistance by direct selection. In some instances also fertility function (tra) could be demonstrated in transductants by further cycles of transfer. It could be speculated that, once such wild-type phages from resistant or toxinogenic strains are liberated into the hospital environment, they could mediate these and other properties to P. aeruginosa strains in that environment.

铜绿假单胞菌对阿米卡星、庆大霉素和妥布霉素耐药的转导
在一系列对庆大霉素、妥布霉素、阿米卡星和/或奈替米星耐药的铜绿假单胞菌菌株中(Knothe and kr msamry, 1979),可以制备野生型噬菌体裂解物,并对其中两种菌株进行了较详细的研究。这两种裂解物均通过直接选择介导庆大霉素、阿米卡星和卡宾西林耐药性的转移。在某些情况下,还可以通过进一步的转移循环在转导剂中证明生育功能(tra)。可以推测,一旦这些来自耐药或毒性菌株的野生型噬菌体被释放到医院环境中,它们可以将这些和其他特性介导给该环境中的铜绿假单胞菌菌株。
