Abstract

Production of hyaluronidase by 147 strains of beta hemolytic streptococci was studied employing a sensitive dye-binding assay and levels of enzyme activity were evaluated statistically. The analysis of variance showed that group A strains isolated in Rio de Janeiro produced significantly smaller amounts of enzyme than group A strains from a Minneapolis (USA) collection or than groups B and G brazilian isolates. The t test revealed that M not typable nose/throat group A strains produced more hyaluronidase than skin isolates. The analysis of variance did not show a significant difference in the enzyme production between M typable and not typable brazilian strains of group A streptococci. High enzyme — producing strains were not restricted to a few serotypes of group B streptococci.

A、B、C和G群链球菌产透明质酸酶的统计分析

采用灵敏染料结合法研究了147株溶血性链球菌生产透明质酸酶的情况，并对酶活性水平进行了统计评估。方差分析表明，巴西巴西里约热内卢地区分离的A群菌株产生的酶量明显低于美国明尼阿波利斯地区的A群菌株，也低于巴西的B和G群菌株。t检验显示M型鼻/喉A组菌株比皮肤分离株产生更多的透明质酸酶。方差分析未显示a群巴西链球菌M型菌株和不可分型菌株的酶产量有显著差异。高产酶菌株并不局限于B组链球菌的少数血清型。
