Genomic characterization of the novel bacteriophage IME183, infecting Klebsiella pneumoniae of capsular type K2.

ABSTRACT

Klebsiella pneumoniae causes a wide range of serious and life-threatening infections. Klebsiella phage IME183, isolated from hospital sewage, exhibited lytic activity against K. pneumoniae of capsular type K2. Transmission electron microscopy revealed that phage IME183 has a head with a diameter of 50 nm and a short tail. Its genome is 41,384 bp in length with a GC content of 52.92%. It is predicted to contain 50 open reading frames (ORFs). The results of evolutionary analysis suggest that phage IME183 should be considered a member of a new species in the genus Przondovirus.
