Neisseria weaveri sp. nov., formerly CDC group M-5, a gram-negative bacterium associated with dog bite wounds.
CDC group M-5 is a rod-shaped, gram-negative, nonmotile bacterium associated with dog bite wounds. DNA-DNA relatedness and biochemical and growth characteristics were studied for 54 strains from the collection at the Centers for Disease Control and Prevention. One typical M-5 strain, 8142, was further studied by 16S rRNA sequencing. ⋯ DNA from M-5 strain 8142 was most closely related to DNA from groups EF-4b (47%) and EF-4a (45%). 16S rRNA sequence analysis placed M-5 strain 8142 in the Neisseriaceae cluster of the beta-3 subgroup of the class Proteobacteria. It was most homologous (98.4 to 98.8%) to Neisseria animalis, Neisseria flavescens, Neisseria canis, and Neisseria elongata. All data are consistent with M-5 being a new species of Neisseria, for which we propose the name Neisseria weaveri.
