| Abstract: |
| 对石家庄市20062007年19起流感疫情暴发的监测资料进行分析，探讨全市流感活动状况。所有咽拭子标本均来自19个疫点的流感样患者，流感样病例均根据“全国流感/人禽流感监测实施方案”确定，并在24h内进行流感病毒分离。检测方法参照“流感及其实验技术”和“全国流感监测实施方案”进行。标本采用狗。肾传代细胞（MDCK）分离培养，每份标本接种2瓶细胞，传两代，特殊情况传三至四代。连传两代都为血凝阴性者，视为病毒分离阴性弃掉。 |
| English Abstract: |
| Objective To establish a rapid method for testing drug sussceptibility on Mycobacterium tuberculosis.Methods Taking absolute Concentration method for drug susceptibility testing of M.tuberculosis as the"gold standard",we examined the drug-resistant of M.tuberculosis strain with nitrate reducrase assay (NRA) and the drug-resistant of M.tuberculosis germ in sputum with NRA. Results NRA and absolute concentration method was basically comparable with NRA susceptibility as 96.5% and the specificity was 100%,When comparing with traditional absolute concentration method, NRA could shorten the time about 3 weeks.Using NRA to test the drug-resistant of M.tuberculosis germ in sputum,its susceptibility was more than 66.7% and specificity was 100%,within 10-20 days. Conclusion NRA could be used as a rapid drug susceptibility testing on M.tuberculosis. |
