Abstract

Genomic analysis was performed on Neisseria meningitidis isolates from four cases of invasive meningococcal disease (IMD) identified in Italy after travel to Saudi Arabia in 2025. The cases were not epidemiologically related. The isolates from the cases were whole genome sequenced and belonged to serogroup W, sequence type (ST)-11, clonal complex (CC)11 and were susceptible to ceftriaxone, ciprofloxacin, penicillin G and rifampicin. Phylogenetic analysis grouped the four genomes with the Hajj strain sublineage.

2025年来自沙特阿拉伯、意大利的4名旅行者中引起侵袭性脑膜炎球菌病的脑膜炎奈瑟菌血清组W的基因组分析

对2025年赴沙特阿拉伯旅行后在意大利发现的4例侵袭性脑膜炎球菌病（IMD）的脑膜炎奈斯菌分离株进行了基因组分析。这些病例在流行病学上没有相关性。病例分离株经全基因组测序，属W血清群，序列型(ST)-11，克隆复合体（CC）11，对头孢曲松、环丙沙星、青霉素G和利福平敏感。系统发育分析将4个基因组归为Hajj菌株亚谱系。
