Microbiological and molecular impacts of AbiK on the lytic cycle of Lactococcus lactis phages of the 936 and P335 species

Abstract excerpt

The lactococcal abortive infection mechanism AbiK was previously shown to be highly effective against the small isometric-headed bacteriophage ul36 of the P335 species, as evidenced by an efficiency of plaquing (e.o.p.) of 10(-6), a 14-fold reduction in the burst size and an efficiency at which centres of infection form (e.c.o.i.) of 0.5%. No phage DNA was detected in the infected AbiK+ cells [Emond, E., Holler,...
