摘要
目的 了解上海市闵行区引发菌痢的志贺菌优势菌型及其与气候之间的关系.方法 采用肛拭标本直接接种于SS平板,分离培养、菌种ATB鉴定仪系统生化鉴定和血清凝集试验对从疑似菌痢腹泻病人中分离的志贺菌进行流行病学分析.结果 1 360例菌痢疑似腹泻病人中检出志贺菌295株,阳性检出率为21.69%,其中春季为17.36%,夏季为19.81%,秋季为28.11%,冬季为7.45%,季节性差异有非常显著性(P<0.01);检出的菌株共分2个血清群,9个血清型,其中宋内氏为26.10%,F4C为24.41%,F2b为19.32%,Fla为17.29%,其他为12.88%.结论 闵行区菌痢四季都有发生,具有季节性差异,秋季为高发期;优势菌型为宋内氏、F4C、F2b、Fla.
Abstract
[ Objective ] To learn the relationship between predominant strains of Shigella and the climate of Minhang District of Shanghai. [Methods] ATB identification media and serum agglutination test were used to carry out epidemiological analysis on the Shigella isolated from the diarrhea patients. [Results] A number of 295 Shegella strains were detected from the 1 360 suspected diarrhea patients with a positive detection rate of 21.69% , among which 17.36% in spring, 19. 81% in summer, 28. 11% in autumn and 7.45% in winter; the seasonal difference was highly significant ( P <0.01 ) ; the detected strain had 2 serum groups, 9 serum types including 26. 10% of Sh. Sonnet, 24. 41% of F4c, 19.32% of F2b, 17.29% of Fla and 12. 88% of others. [ Conclusion] Shegella occurs in every season in Minhang District with seasonal difference, autumn is the most typical one; the predominant strains of Shigella were Sh. Sonnet, F4C, F2b and Fla.
