Characteristics of Group. Streptococci Isolated from Children with Non-Suppurative Complication or Severe Infection

We determined the characteristics of group. streptococci isolated from 29 sporadic cases with non-suppurative complication or severe infection during. 15-year period from 1977 to 1991. The clinical diagnoses of children included. patients with rheumatic fever, 2 with reactive arthritis, 2 with central nervous system complication, 5 with glomerulonephritis, 11 with Honoch-SchOnlein purpura, 4 with sepsis and. with empyema. Twenty-four strains were isolated from throat swabs, 4 from blood specimens and one from pleural fluid. M/T-serotypes and the number of isolates were as follows; 1/1: 10, 3/3: 1, 3·3R/3: 3, 4/4: 7, 5/NT: 1, 12/12: 3, 18/18: 2, 62/12: 1, NT/13: 1. All 29 isolates had productivity for at least one of streptococcal pyrogenic exotoxins (SPEs) A, B and C. Two strains were positive for A, 2 for. and B, 3 for A, B and C, 9 for. and 13 for. and C. Of 11 isolates from patients with Henoch-SchOnlein purpura, 7 and. strains were serotyped in M1 and M4, respectively, but none was in M12. Ten of 11 isolates were positive for SPE. or SPEs. and C.
