Abstract/OtherAbstract:
|
Streptococci of serological groups A (GAS), B (GBS), C (GCS) and G (GGS) were examined in vitro using an optimized medium in respect of their ability to produce hyaluronic acid (HA) and hyaluronatlyase (HY). In this study, 614 GAS (including 123 streptococcal toxic shock syndrome strains, STSS), 247 GBS, 225 GCS and 143 GGS were investigated in qualitative and quantitative tests. Only 4% of GAS and 2.7% of GCS were able to express HA. In contrast to GAS, isolates of GCS showed a highly specific HA formation (to 1 g HA/g dry biomass). In all strains of GBS and GGS, not even a single isolate was positive for HA. HY expression was detectable in all four serological groups. In GAS, only 12.5% of strains were positive; the most common types being 22 and 4, whereas in GBS, GCS and GGS, 72.1%, 84% and 85.3% of isolates, respectively, could be reported as positive. The data suggest that the HA capsule only plays a secondary role in infections caused by GAS strains pathogenic for humans. |
