The capsular polysaccharide of phage SH-KP2492 non-lytic K62 strains. A Uronic acid assay was performed on phage lytic strains (17–87 and 18–195) and phage non-lytic strains 17–349 and 18–448. Strains 17–349 and 18–448 had a significantly lower amount of polysaccharide capsule uronic acid than strains 17–87 and 18–195. Data are shown as mean ± SEM. B. The wbaP gene variants in phage non-lytic K62 strains. Mutations found in the capsule biosynthesis gene wbaP in nonencapsulated isolates
