A Highly Arginolytic Streptococcus Species That Potently Antagonizes Streptococcus mutans.

abstract：:Various Listeria monocytogenes strains may contaminate a single food product, potentially resulting in simultaneous exposure of consumers to multiple strains. However, due to bias in strain recovery, L. monocytogenes strains isolated from foods by selective enrichment (SE) might not always represent those that can bet...
