Abstract

Nine isolates, which were obtained from tonsils, anal swabs and faeces of dogs and from tonsils of a cat and a calf, constituted a homogeneous but unidentified taxon after screening with tRNA intergenic length polymorphism analysis and whole-cell protein fingerprinting. 16S rDNA sequence analysis classified representative strains in the genus Streptococcus. Highest sequence similarity (95·9 %) was obtained with Streptococcus ovis. Growth characteristics, biochemical features, DNADNA hybridization and DNA G+C contents of selected strains demonstrated that they represent a single, novel streptococcal species. The name Streptococcus minor sp. nov. is proposed for the novel species; the type strain (ON59T=LMG 21734T=CCUG 47487T) was isolated from a dog tonsil.
