Biochemical properties and whole‐cell protein profiles of group G streptococci isolated from dogs

摘要

Whole‐cell protein profiles obtained by SDS‐PAGE were used in conjuction with physiological tests to differentiate strains ofStreptococcus canisisolated from dogs. Fermentation of trehalose and lactose, aesculin hydrolysis together with production of β–D–glucuronidase and α–D–galactosidase allowed the demonstration of nine different biotypes. However, visual analysis of the protein patterns andcomparison by the coefficient of Dice showed minor differences in band patterns among strains. Only two different profiles were observed. Although a correlation between biotypingand protein profile has been found, this kind of analysis did not provide the basis for a
