Biochemical and molecular genetic studies were performed on an unknown Gram-positive, catalase-negative, coccus-shaped organism isolated from clinical samples from pigs. On the basis of the results of cellular morphological and biochemical tests, the organism was identified as a streptococcal species. 16S rRNA gene sequence comparisons confirmed its identification as a member of the genus Streptococcus, but the organism was distinct from any recognized species of this genus. The closest phylogenetic relative of the unknown organism corresponded to Streptococcus suis NCTC 10234T (97.2 % 16S rRNA gene sequence similarity) and this phylogenetic position was confirmed by analysis of rpoB and sodA sequences. DNA–DNA hybridization studies showed that the unidentified organism produced a DNA reassociation value of 36.6 % with respect to S. suis NCTC 10234T. The novel bacterium was distinguished from S. suis and other Streptococcus species using biochemical tests. On the basis of phenotypic and phylogenetic data, the unidentified organism represents a novel species of the genus Streptococcus, for which the name Streptococcus plurextorum sp. nov. is proposed. The type strain is 1956-02T (=CECT 7308T=CCUG 52972T).

The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA, rpoB and sodA gene sequences of strain 1956-02T are AM774228, AM774232 and AM774230, respectively; those for strain 1355-03 are AM774229, AM774233 and AM774231, respectively.

A complete neighbour-joining phylogenetic tree, based on 16S rRNA gene sequences, showing the position of strain CECT 7308T with respect to Streptococcus reference species, is available with the online version of this paper.
