Neisseria bacilliformis sp. nov. isolated from human infections.

ABSTRACT: Most Neisseria species are gram-negative cocci or diplococci; currently, N. elongata is the only species of human origin with a bacillary morphology. Here, we report isolation and characterization of eight strains of another bacillary Neisseria species from human infections. The organisms caused or contributed to either oral cavity-related or respiratory tract infections, and two strains were isolated from blood cultures. The 16S rRNA gene sequences of these organisms, being homogenous or nearly so (99.4 to 100% identity), matched at <96% known Neisseria species and formed a distinct group within the genus. Analysis of the cellular fatty acids showed broad similarity with a few Neisseria species. The organisms were gram negative and measured 0.6 mum by 1.3 to 3.0 mum. They grew well on cho
