Isolation and Lysis Spectrum Analysis of Acinetobacter Bacteriophages / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To isolate Acinetobacter bacteriophages and analyze their lysis spectrum.METHODS A total of 78 Acinetobacter strains were isolated from the sewage of different sources whose lysis spectrum was determined by method of single layer plates.RESULTS From them only two kinds of Acinetobacter bacteriophages AB46 and AB54 with different lysis spectrum were isolated from 2 strains.The former had a lysis spectrum of 46(1.28%)and the latter had a lysis spectrum of 54,57,59,60,62,69,70 and 78(10.27%).CONCLUSIONS Acinetobacter bacteriophages are isolated and their lysis spectrums are obtained.The lysis spectrums are narrow which need to improve their lysis ranges but they can infect their hosts virulently and form transparent plaques.
