Abstract

We report on the performance of a recently introduced commercial chessboard method using 12 antisera, in comparison with that of the 55-antiserum panel used in determining the serogroups and types (SGTs) of Streptococcus pneumoniae, both of which were carried out by a coagglutination technique. Of a total of 150 strains of S. pneumoniae studied, 135 (90%) belonged to the SGTs represented in the 23-valent pneumococcal vaccine; of these, 130 (96.3%) were identified as the same SGTs by both typing methods. The remaining five strains showed cross-reactivity with more than two pools by the chessboard method, but could be assigned to a single SGT by the Quellung test. The 96.3% concordance of the chessboard method suggests it can be adopted for determination of the SGTs of S. pneumoniae in laboratories.

摘要

我们报告了一种最近推出的使用12种抗血清的商用棋盘法的性能,并将其与用于确定肺炎链球菌血清群和血清型(SGTs)的55种抗血清板的性能进行了比较,这两种方法均通过协同凝集技术进行。在总共研究的150株肺炎链球菌中,135株(90%)属于23价肺炎球菌疫苗中所包含的血清群和血清型;其中,两种分型方法将130株(96.3%)鉴定为相同的血清群和血清型。其余五株菌株通过棋盘法与两个以上的组合显示出交叉反应,但通过荚膜肿胀试验可归为单一的血清群和血清型。棋盘法96.3%的一致性表明它可在实验室中用于肺炎链球菌血清群和血清型的测定。
