Objective · To screen for a bacteriophage of a drug-resistant Klebsiella pneumoniae strain and assess its eligibility to be incorporated into the Klebsiella bacteriophage library. Methods · A drug-resistant Klebsiella pneumoniae strain isolated a patient with urinary infection was used as the host strain. Phage screening was carried out in environmental sewage, and the bacteriophage was isolated, purified, characterized and sequenced. Safety evaluation was also conducted based on the genome sequence. Results · A drug-resistant Klebsiella pneumoniae bacteriophage was isolated and designated as JD902, which belonged to Caudovirales. The burst size was 88 pfu/cell, and it could maintain good activity in pH range 4.0-11.0. Genomic analysis demonstrated that it did not carry any antibiotic resistance genes and virulence factor genes. Conclusion · JD902 is a virulent phage with high stability and safety in vitro. It can be incorporated into bacteriophage library for clinical treatment.
