Figure 1. Bactericidal effects of endolysin λSa2lys and Art-240 against different bacterial species.
A cell suspension of several streptococcal species, S. aureus LiCC S20, E. faecium LiCC S1055 Salmonella Typhimurium LiCC LiCC S25 and E. coli (O157:H7) LiCC S72 were treated with equimolar amounts (0.1 μM) of λSa2lys (grey) endolysin and Art-240 (white). Bacterial reduction after 1 h is expressed in log units relative to the untreated control. Data reported are means ± standard deviations of three replicates. Student t-test was performed to compare the bactericidal activity of λSa2lys and Art-240. *P < 0.05; **P < 0.01.
