Interspecies Interactions Between Streptococcus Mutans and Streptococcus Agalactiae in vitro.

abstract：:More than a decade ago a short tandem repeat-based typing method was developed for the fungus Aspergillus fumigatus. This STRAf assay is based on the analysis of nine short tandem repeat markers. Interpretation of this STRAf assay is complicated when there are only one or two differences in tandem repeat markers betwe...
