Based on a pair of primers developed initially for differentiating the anginosus group from other viridans streptococci, the PCR reported here can also differentiate between members of the anginosus group and Streptococcus dysgalactiae subsp. equisimilis among beta-hemolytic group C and G streptococci. The resulting 742-bp PCR product was specific for members of the anginosus group, although a ...

The enzymes which are released into the environment by pathogenic microorganisms are of importance in a consideration of the mechanism of disease processes, since they may play a rtle in the virulence and invasiveness of the bacteria as well as in specific tissue injuries. In this connection, it is of interest that certain of the bacterial exotoxins have recently been demonstrated to be enzymat...

The grouping of beta-hemolytic streptococcal isolates by a new direct-plate procedure employing Phadebact Streptococcus Test reagents was compared with the results obtained with the 4- and 24-h Phadebact grouping procedure and with the Lancefield grouping obtained with a capillary precipitin test. The new procedure employed a modification of the Phadebact procedure that permitted the grouping o...

Marked degeneration and disintegration of the chick embryo fibroblast was observed in tissue cultures after their exposure to sera of patients with active or inactive rheumatic heart disease or to the filtrates of beta hemolytic streptococci. Some tissue specificity was demonstrated; sera of the patients or the filtrates of the streptococci failed to affect contractility of the myocardial cells...

PharyngltlS is one of the most common illnesses seen in the pnmary medical care of children. Most cases are of viral etiology, while others are mainly bacterial (I,2). The most prevalent bacterial pharyngitis is due to 8-hemolytic streptococci (BHS), which are. responsible for suppurative and nonsuppurative complicat10nS and are potentially highly transmissible. However, microbiologic data rega...

Bacteriol. 89:529-534. 1965.-Ten strains of beta-hemolytic streptococci with unusual somatic antigens were isolated from excised tonsils or throat cultures or both. Acid extracts of these strains reacted with comm...
