Characterization of Morococcus cerebrosus gen. nov., sp. nov. and Comparison with Neisseria mucosa

We propose the name Morococcus cerebrosus gen. nov., sp. nov. for a gramnegative, oxidase-positive, aggregate-forming coccus that was isolated from a brain abscess. The type strain is UQM 858 (= ATCC 33486 = NCTC 11393). A comparative study of this organism with Neisseria mucosa showed that the deoxyribonucleic acid base ratios of these two species were comparable but that there were sufficient differences in their physiological, cultural, serological, and morphological characteristics to warrant the proposal of this taxon as a new genus in the family Neisseriaceae.
