Excessive C5 conversion prevents C9 polymerisation and subsequent MAC-dependent killing of Klebsiella pneumoniae

This study shows that excessive C5 conversion in Klebsiella pneumoniae strains limits C9 polymerisation, preventing MAC-dependent killing, but adding C9 restores killing, indicating these strains are not truly resistant.
