| 中文摘要: |
1.用活性炭吸附伤寒杆菌“O”提取物制备炭抗原，与118例疑似伤寒患者和36例经细菌学培养证实为伤寒病患者的血清作炭凝试验，其阳性率分别为72%和100%；肥达氏反应阳性率分别为62.7%和77.8%。
2.炭凝试验操作简便，易于掌握，不受设备和条件限制，所得结果迅速，适宜基层使用。 |
| 英文摘要: |
| The O-antigen was extracted from Sal. Typhi and adsorbed by activated carbon as carbon-antigen. The agglutination test was carried out with such an antigen to examine 154 samples of sera, including 118 from suspected cases. The remaining 36 samples were from bacteriologically confirmed typhoid patients. The positive rates were 72% and 100% respectively, while the Widal positive reaction gave only 62.7% and 77.8%. Not only is the charcoal agglutination test easily manipulated but also time-saving. Thus it can be widely adopted by primary health centers. |
