Table 1 Morphological features and plaque morphology of isolated Klebsiella pneumoniae bacteriophages

From: Characterization of four virulent Klebsiella pneumoniae bacteriophages, and evaluation of their potential use in complex phage preparation

Morphology Phage vB_KpnS_FZ10 Phage vB_KpnS_FZ41 Phage vB_KpnP_FZ12 Phage vB_KpnM_FZ14
Isometric capsid, long non-contractile tail Isometric capsid, long non-contractile tail Isometric capsid, short non-contractile tail Isometric capsid, long contractile tail

  1. Head diameter is calculated for isometric capsids. All measurements were made with ImageJ program, 35 particles were measured for each phage and standard deviation was calculated (± SD). Clear plaque size is the calculation of transparent plaque zone diameter, presence of halo is indicated with “ + ”, absence with “- “
