Heikkila and Saris (2003) investigated inhibition of S. aureus by
the commensal bacteria of human milk. They reported that onefifth
of S. epidermidis and half of Streptococcus salivarius isolates
suppressed growth of S. aureus. Enterococci (Enterococcus faecalis),
isolated from 7.5% of samples, and LAB isolated from 12.5% of
samples, were also effectively inhibited by S. aureus. The research
supports considerable contributions to the current study when
compared, but our study showed that all S. epidermidis strains
isolated from human breast milk samples demonstrated inhibitory
activity of S. aureus with zone diameters in the range of 10e23 mm
(Table 1).
