Forty-eight strains of Streptococcus pneumoniae were tested in vitro to determine the minimum number required for pneumococcal capsular antigen to be detectable by latex agglutination. It was found that 10(6) to 10(7) microorganisms per ml were needed and that antigen remained detectable even when viable pneumococci could no longer be demonstrated.
对48株肺炎链球菌进行了体外测试,以确定通过乳胶凝集法检测肺炎球菌荚膜抗原所需的最小菌数。结果发现,每毫升需要10(6)至10(7)个微生物,并且即使无法再证明有活的肺炎球菌,抗原仍可检测到。
