SARM1 and susceptibility to pneumonia measurement: Importantly, these polysaccharides are required for KP survival in mice (pneumonia model) (Cortes et al., 2002; Lawlor et al., 2005; Tomas et al., 2015), underlining the importance of SARM1 induction as a KP virulence trait since this process is abrogated in these mutant strains.
