Fig. (3).Effect of pmp23::kan mutation on penicillin-induced lysis and death.

S. pneumoniae R6 strain (triangle) and pmp23::kan mutant (circle) were exposed (closed symbols) or not (open symbols) to 0.06 µg/ml of Penicillin G in TH broth. The arrow indicates Penicillin G addition. In each case, one representative of four experiments at least is shown.

A. Lysis of S. pneumoniae R6 strain and pmp23::kan mutant in presence or absence of Penicillin G.

B. Viability of S. pneumoniae R6 strain and pmp23::kan mutant in presence or absence of Penicillin G.
