During two epidemics of influenza A infection in Stockholm 1969-72, 249 cases were selected for a study on the effect of bacterial superinfection. Bacterial involvement was demonstrated through cultures and serologic reactions. The occurrence of C-reactive protein in increased amount in serum was significantly more common in the group which had the strongest indication of bacterial infection. An increased duration of fever, and a higher incidence of pneumonia, leukocytosis and erythrocyte sedimentation rate over 50 mm/l h was also the rule in cases with bacterial involvement. During both epidemics the bacteria most often involved were pneumococci.
在1969年至1972年斯德哥尔摩的两次甲型流感感染流行期间,选取了249例病例进行细菌重叠感染影响的研究。通过培养和血清学反应证实有细菌感染。血清中C反应蛋白含量增加在细菌感染迹象最明显的组中显著更为常见。发热持续时间延长,以及肺炎、白细胞增多和红细胞沉降率超过50mm/1小时的发生率更高,在有细菌感染的病例中也是常见情况。在两次流行期间,最常涉及的细菌是肺炎球菌。
