Abstract
This report describes the C-to-B capsular switching in four Neisseria meningitidis strains belonging to the electrophoretic type 37 (ET-37) complex. In particular, one strain belonged to the new sequence type 1860, which was first detected in the year 2000 in Italy and is now frequently isolated. The presence of switched serogroup B strains deserves special attention if they prove as able to spread as their serogroup C progenitors belonging to the hypervirulent ET-37 complex.
摘要
本报告描述了4株属于电泳型37（ET-37）复合体的脑膜炎奈瑟菌的C群到B群荚膜转换。特别地，其中一株属于新的序列型1860，该序列型于2000年在意大利首次检测到，目前经常被分离出来。如果转换后的B群菌株证明与属于高毒力ET-37复合体的C群祖先菌株一样具有传播能力，那么它们的存在值得特别关注。
