We report results of surveillance for cholera caused by Vibrio cholerae O139 from September 1992, when it was first identified, to December 1998. V. cholerae O139 dominated as the causative agent of cholera in Calcutta during 1992-93 and 1996- 97, while the O1 strains dominated during the rest of the period. Dramatic shifts in patterns of resistance to cotrimoxazole, neomycin, and streptomycin were observed. Molecular epidemiologic studies showed clonal diversity among the O139 strains and continuous emergence of new epidemic clones, reflected by changes in the structure, organization, and location of the CTX prophages in the V. cholerae O139
我们报告了对1992年9月(霍乱弧菌O139首次被鉴定)至1998年12月期间由霍乱弧菌O139引起的霍乱的监测结果。在1992 - 1993年和1996 - 1997年期间,霍乱弧菌O139是加尔各答霍乱的主要病原体,而在其余时间段O1菌株占主导地位。观察到对复方新诺明、新霉素和链霉素的耐药模式发生了显著变化。分子流行病学研究表明,O139菌株之间存在克隆多样性,新的流行克隆不断出现,这通过霍乱弧菌O139中CTX噬菌体的结构、组织和位置变化得以体现。
