这些病例调查可能有助于确定传播途径。欧洲于2005年作为病例报告对耐多药结核病(MDR TB)进行了分子监测。对于2003年1月至2007年6月发现的所有新的耐多药结核病病例,各国报告了基于病例的流行病学数据和耐多药结核病菌株的DNA指纹模式(如果有)。对国际集群进行了检测和分析。从2003年到2007年年中,欧洲24个国家报告了2494例耐多药结核病病例。流行病学和分子数据与593例(39%)病例相关联,来自19个国家的672个插入序列6110个DNA指纹图谱被报告。在这些模式中,288个(43%)属于18个欧洲聚类群,7个聚类群(242/288例,84%)具有北京基因型家族的菌株特征,其中最大的聚类群(175/288例,61%)。聚集性和北京基因型都与起源于东欧国家的毒株有关。分子簇检测有助于识别传播概况、危险因素和控制措施。
These case investigations may help identify routes of transmission. Molecular surveillance of multidrug-resistant tuberculosis (MDR TB) was implemented in Europe as case reporting in 2005. For all new MDR TB cases detected from January 2003 through June 2007, countries reported case-based epidemiologic data and DNA fingerprint patterns of MDR TB strains when available. International clusters were detected and analyzed. From 2003 through mid-2007 in Europe, 2,494 cases of MDR TB were reported from 24 European countries. Epidemiologic and molecular data were linked for 593 (39%) cases, and 672 insertion sequence 6110 DNA fingerprint patterns were reported from 19 countries. Of these patterns, 288 (43%) belonged to 18 European clusters; 7 clusters (242/288 cases, 84%) were characterized by strains of the Beijing genotype family, including the largest cluster (175/288 cases, 61%). Both clustering and the Beijing genotype were associated with strains originating in eastern European countries. Molecular cluster detection contributes to identification of transmission profile, risk factors, and control measures.
