Inhibition of growth of S. Enteritidis WT and Δ sodC mutant in the presence of CFCS (A) of KSBT 56 or live KSBT 56 (B). A. S. Enteritidis (SEn) WT or a mutant strain deficient of sodC gene (ΔsodC) were co-incubated with CFCS. B. The above groups were also co-incubated with live KSBT 56 bacterial culture. The cfu was enumerated by plating on LB agar plates supplemented with streptomycin. The presence of CFCS or KSBT 56 is indicated by (+) and the absence is indicated by (−). The growth of ΔsodC is compared with S. Enteritidis WT strain grown in the presence of CFCS or live KSBT 56 strain.
