Production of pyrogenic exotoxins in group A streptococci isolated from patients in Zagreb, Croatia.
The pyrogenic exotoxin profiles were determined of group A streptococci isolated from patients in Zagreb, Croatia in the period 1989-1990. A total of 12 strains were studied, five from patients with serious infections and seven from patients with uncomplicated infections. Serotypes M1 and M3 were found in seven (58%) patients. Seven strains produced exotoxin A and ten strains exotoxin B. The proportion of exotoxin A and B producing strains in patients with severe infections (3 patients respectively) was similar to that found in patients with uncomplicated infections (4 and 7 patients respectively).
