The resulting protein patterns were examined to identify the bands of major and minor frequency within the genus. A cluster analysis revealed three major Rothia groups and a fourth group representing the genus Actinomyces. Our data demonstrated good correlations (>70%) with existing biotyping and serotyping schemes of these isolates. We suggest that electrophoretic group 2 represents a new Rothia species., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-34-2-102
