Streptococcus orisuis sp. nov., isolated from the pig oral cavity.
Five bacterial strains, designated as NUM 1001(T), NUM 1002, NUM 1003, NUM 1004 and NUM 1005, were isolated from the oral cavities of pigs. Colonies grown on mitis salivarius agar were similar in morphology to those of mutans streptococci. The novel isolates were analysed biochemically using the Rapid ID 32 Strep microsystem, subjected to DNA-DNA hybridization with oral streptococci and had their 16S rRNA genes sequenced. On the basis of the phylogenetic and phenotypic evidence obtained, the strains represent a novel species of the genus Streptococcus, for which the name Streptococcus orisuis sp. nov. is proposed. The type strain is NUM 1001(T) (=JCM 14035(T)=DSM 18307(T)).
