A polyphasic taxonomic study was performed on isolates classified as Centers for Disease Control Group Eugonic Fermenter (EF)-4a and EF-4b. Comparative 16S rRNA gene sequence analysis confirmed that group EF-4a and EF-4b belong to the genus Neisseria with Neisseria canis and Neisseria dentiae as the nearest phylogenetic neighbours. DNA-DNA hybridizations and biochemical analyses demonstrated that isolates of group EF-4a and EF-4b represent two novel species within this sublineage of the genus Neisseria. Based on the results of the present study, isolates of group EF-4a and EF-4b are classified as Neisseria animaloris sp. nov. (type strain LMG 23011(T)=NCTC 12228(T)) and Neisseria zoodegmatis sp. nov. (type strain LMG 23012(T)=NCTC 12230(T)), respectively.
对分类为疾病控制中心优氧发酵菌（EF）-4a和EF-4b的分离株进行了多相分类研究。比较16S rRNA基因序列分析证实，EF-4a和EF-4b组属于奈瑟菌属，犬奈瑟菌和齿龈奈瑟菌为最近的系统发育邻属。DNA-DNA杂交和生化分析表明，EF-4a和EF-4b组的分离株代表奈瑟菌属该亚谱系内的两个新物种。根据本研究结果，EF-4a和EF-4b组的分离株分别被分类为新动物奈瑟菌（模式菌株LMG 23011(T)=NCTC 12228(T)）和新动物溃疡奈瑟菌（模式菌株LMG 23012(T)=NCTC 12230(T)）。
