ABSTRACT
Four thousand, three hundred and ninety five throat, 4,395 nasal and 58 skin lesion swab-specimens were examined bacteriologically out of which 401 (9.12%) were positive for beta-haemolytic streptococel (GHS) and 11 (0.25%) for non- haenolytic streptococci (NS). On the basis of Lancefield group polysaccharide antigens, the 1solates were classified into groups A, C, D, G and non-groupable BHS strains. On the basis of bacitracin sensitivity and blochemical analysis, these groups and ungroupable BHS strains were classified further into Street, pyogenes, Strept.sguisintis, Strept, cants and Strept. milleci.
Six members of group A, 68 of group C and 117 of group G BHS isolates were further examined for evidence of streptolysin D (sco), deoxyribonuclease B (DNase B), hyaluronidase, M-associated protein (UP), serum opacity factor (SOP), proteinase, M, T and protein antigens. These antigenic components were observed in varying percentages of the Isolatesi ali (100.0%) the six members of group A were positive for SLO and MP, five (83.3%) for DNase B and hyaluronidase, three (50.0%) for SOP and four (66.6%) for proteinase activity: 41 (60.29%) of group C for SLO and MAP, 52 (76.47%) for DNase B, 56 (B2.35%) for hyaluronidase, and nil (0.0%).
