Effects of endoglycosidase-H treatment on Kpkt killer activity.

Conditions	After 24 h incubation (CFU × 105 ml-1)	After 48 h incubation (CFU × 105 ml-1)
Without Kpkt	17.0 ± 1.27	56.0 ± 8.48
With Kpkt	0.5 ± 0.14	0.03 ± 0.016
With Kpkt + Endo H	6.4 ± 0.42	6.7 ± 0.56
With Kpkt and without Endo H	0.29 ± 0.098	0.43 ± 0.013

The initial inoculum of sensitive cells was 2 × 10⁵ cell ml^-1. Data are means ± SD of three experiments.
