Figure 6. Survival of Galleria mellonella larvae infected with Klebsiella pneumoniae strains isolated from patients at a tertiary hospital in Ningbo, Zhejiang Province, China, August 1, 2020–June 30, 2021. A hypervirulent K. pneumoniae K2 strain ATCC 43816 was used as the positive control. A phosphate-buffered saline–injected and a pricking larval group (empty needle injection, uninfected) served as negative control groups. Data are pooled from >3 independent experiments with 10 larvae per group per run. The representative results are displayed. cKP, classical K. pneumoniae; PBS, phosphate-buffered saline.
