Abstract
Over six months 10 biochemically and physiologically atypical strains of Streptococcus pneumoniae were isolated from eye swabs. Conventional methodology showed that these strains possessed characteristics of both S pneumoniae and other alpha haemolytic streptococci. The use of sodium dodecyl sulphate - polyacrylamide gel electrophoresis (SDS-PAGE) enabled us to characterise these strains as S pneumoniae. Loss of the capsule seemed to be associated with atypical biochemical properties.
摘要
在六个月的时间里，从眼拭子中分离出10株生化和生理特性不典型的肺炎链球菌菌株。传统方法显示，这些菌株兼具肺炎链球菌和其他α溶血性链球菌的特征。使用十二烷基硫酸钠-聚丙烯酰胺凝胶电泳（SDS-PAGE）使我们能够将这些菌株鉴定为肺炎链球菌。荚膜的缺失似乎与不典型的生化特性有关。
