Surprisingly, the similarity rates are not in accordance with 16S
rDNA identification results. It was expected to be classified under
same subgroups of the strains N112 and N111, at least which were
identified as S. hominis and isolated from same breast milk. In
general, it can be concluded that all these isolates belong to same
genus, Staphylococcus, but they begin to diverge when analyzed in
terms of species. The present study results suggest that PFGE
electrophoresis is a tool that the results obtained by PFGE should be
combined with other characterization methods. In this study, ApaI
restriction enzymewas used to cut the genomic DNA of the isolates,
but it is common to use two or more enzymes to help screen the
data in a broader perspective.
