Serum-mediated killing of isolates K1, K5 and non- hypermucoviscous (NHM) Klebsiella pneumoniae and Escherichia coli. LOG CFU/mL of bacteria 1 h post-incubation in heat-inactivated serum (A) or normal serum (B) recovered from seronegative (dark bars) or seropositive (clear bars) African Green monkey. The error bars represent standard errors for triplicate samples, and the results shown are representative of three independent experiments. The error bars represent standard errors for triplicate samples, and the results shown are representative of three independent experiments. Asterisk indicates significant difference between treatments, p ≤ 0.05; Double asterisk indicates significant difference between treatments, p ≤ 0.001; Equal to indicates similarity between treatments, p > 0.05.
