金黄色葡萄球菌抗体在诊断金黄色葡萄球菌L型败血症中的意义

THE EFFECTS OF THE STAPHY LOCOCCUS AUREUS ANTIBODY ON DIAGNOSIS OF STAPHY LOCOCCUS AUREUS L-FORM SEPTICAEMIA

目的：探讨测定金黄色葡萄球菌（简称金葡菌）抗体在金葡菌Ｌ型败血症中的意义。方法：金葡菌Ｌ型败血症的细菌诊断组３８例，临床诊断组４６例及对照组４１例的血清做试管定量凝集反应测定其效价。并以金葡菌细菌型和Ｌ型分别感染动物，停止感染两个月后测定抗体滴度。结果：以１：８０以上作为阳性，阳性率细菌诊断组９４７％、临床诊断组８６９％、而对照组仅１４６％。细菌诊断组及临床诊断组均明显高于对照组（Ｐ〈０００５），而细菌诊断组与临床诊断组比较无显著差异（Ｐ〉００５）。结论：金葡菌抗体在金葡菌Ｌ型败血症中具有快速的病原学辅助诊断作用。

Obfective:To study the measuring of the effects of the staphylococcus aureus antibldy in staphylococcus aureus L-form septicaemia.Methods:Prepare 38 serum samples of the staphylococcus aureus L-form septicaemia bacteria diagnosis group,46 of the clinical diagnosis group and 41 of the comparison group which are to be tested for their test tube agglubination titer.Infect animals with bacteria and L-form staphylococcus aureus then measure the antibody titer two months laterafter the infections are stopped.Results:Those which are not below 1:80 are considered positive.94.7% of the bacteria diagnosis samples group,86.9% of the clinical diagnosis group were tested positive,only 14.6% of the cmoparison group had the same results.The positive rate of the bacteria and clinical diagnosis group are obviously higher than that of the comparison group (P<0.05),but there is no apparent differ-ence between the bacteria and the clinical group (P>0.05). Conclusion:The staphy-lococcus aureus antibody conveys great effectiveness over quick etiology-aided diag-nosis of the staphylococcus aureus L-form septicaemia.
