Fig. 1From: Rapid identification of capsular serotype K1/K2 Klebsiella pneumoniae in pus samples from liver abscess patients and positive blood culture samples from bacteremia cases via an immunochromatographic strip assayThe results of serotypes K1 and K2 K. pneumoniae identification by different typing methods. a Capsular swelling test showing capsular serotypes K1/K2 following reaction with K1 and K2 antiserum. Saline (0.9%) was used as control. Images were captured using a phase contrast microscope (original magnification, 1000×). b Capsular serotypes K1/K2 detected by the PCR testing. Visualization of the bands on an agarose (1.5%) gel for the capsular serotypes K1/K2 strains (K1, K2). Size of each amplicon is indicated at the side. M, markers. c Capsular serotypes K1/K2 detected by means of ICSs. The red line in the ICS indicated serotype K1 or K2 is shownBack to article page
