Interpretive Summary: Organisms named Paenibacillus pulvifaciens have been implicated in honeybee diseases. Some members, called group II, may not be pathogenic and their classification has been doubted. This doubt could cause confusion in the recognition of diseases should they occur. Comparison of their genetic materials with those of known organisms showed that group II strains were not members of the P. pulvifaciens but another group called Brevibacillus agri.

Technical Abstract: Organisms formerly identified as strains of Paenibacillus pulvifaciens group II were reclassified as members of the species Brevibacillus agri. The reclassification was based on phylogenetic analyses of 16S rRNA gene sequences of selected Bacillaceae. The analysis strongly supported placement of group II strains in the genus Brevibacillus. High DNA relatedness of 96 to 100 percent demonstrated that group II strains were members of the species Brevibacillus agri.
