A survey of ABO blood groups, secretor status and smoking habits among 389 students and staff of a school in which there was an outbreak of meningococcal disease found no difference in the distribution of the ABO blood groups but a significantly higher proportion of non-secretors (37.6%) in the population examined compared with that reported for previous surveys of the neighbouring population in Glasgow (26.2%) (P less than 0.0005). There was also a significantly higher proportion of non-secretors among carriers of meningococci (47%) compared with non-carriers (32%). Increased carriage of meningococci among non-secretors might contribute to the increased susceptibility of individuals with this genetic characteristic to meningococcal disease observed in previous studies. Although passive exposure to cigarette smoke has been associated with meningococcal disease, there was no association between passive smoking and carriage. There was, however, a significant association between active smoking and carriage.
对一所学校的389名学生和教职员工进行了ABO血型、分泌型状态和吸烟习惯调查,该校曾爆发过脑膜炎球菌病。结果发现,ABO血型分布没有差异,但与格拉斯哥附近人群先前调查报道的比例(26.2%)相比,受检人群中非分泌型的比例显著更高(37.6%)(P小于0.0005)。脑膜炎球菌携带者中非分泌型的比例(47%)也显著高于非携带者(32%)。非分泌型人群中脑膜炎球菌携带率增加可能是先前研究中观察到的具有这种遗传特征的个体对脑膜炎球菌病易感性增加的原因。虽然被动接触香烟烟雾与脑膜炎球菌病有关,但被动吸烟与携带情况之间没有关联。然而,主动吸烟与携带情况之间存在显著关联。
