RADIATION RESISTANCE OF ACINETOBACTER SPP.

摘要

The radiation resistance of 78 different strains of Acinetobacter sp. 42 from clinical isolates and 36 from other sources were compared with 15 clinical isolates and 12 other strains from Denmark. None of the Canadian strains was as resistant as resistant-enhanced Danish strains. Four strains had D_(10) values of 3.1-3.6 kGy. Irradiated and unirradiated cells from all strains grew well, when cultured in Trypticase-Soy Broth at 30℃. Most cultures grew after overnight incubation. It was concluded that there would be no difficulty in detecting these strains, using ISO methodology for establishing the radiation sterilization dose for devices.
