由外膜蛋白PorA的变异定义的亚型是脑膜炎奈瑟菌表征方案的组成部分。这些变种的鉴定仍然很重要,因为PorA蛋白是正在开发的几种脑膜炎球菌疫苗的主要免疫原性组分,并且PorA的特征用于提供详细的流行病学信息。历史上,血清亚型已通过与一组单克隆抗体的反应性来定义。然而,porA基因的核苷酸序列分析已经确定,血清亚型单克隆抗体的面板是不详尽的,许多porA变异体不能检测。此外,用于定义亚型的命名系统是不适当的。我们检查了porA VR 1和VR 2区域的所有可用核苷酸序列,以识别和定义亚型家族。修订命名方案,兼容以前的血清学命名方案,设计。建立了一个可在网上访问的数据库,其中描述了这一命名法及其与以前方案的关系(可查阅:http://neisseria.org/nm/typing/pora)。
Subtypes, defined by variation in the outer membrane protein PorA, are an integral part of the characterization scheme for Neisseria meningitidis. Identification of these variants remains important as the PorA protein is a major immunogenic component of several meningococcal vaccines under development, and characteristics of PorA are used to provide detailed epidemiologic information. Historically, serosubtypes have been defined by reactivity with a set of monoclonal antibodies. However, nucleotide sequence analyses of porA genes have established that the panel of serosubtyping monoclonal antibodies is not exhaustive and many porA variants cannot be detected. In addition, the nomenclature system used to define subtypes is inadequate. We examined all available nucleotide sequences of the porA VR1 and VR2 regions to identify and define subtype families. A revised nomenclature scheme, compatible with the previous serologic nomenclature scheme, was devised. A Web-accessible database describing this nomenclature and its relationship to previous schemes was established (available from: http://neisseria.org/nm/typing/pora).
