Biochemical and molecular genetic studies were performed on two novel Gram-stain-positive, catalase-negative, coccus-shaped organisms isolated from liquid joint samples of two pigs. The micro-organisms were not identified as members of a recognized species based on results of cellular, morphological and biochemical tests. 16S rRNA gene sequence comparison studies allowed their identification as members of the genus Jeotgalibaca, but the organisms were different to Jeotgalibaca dankookensis, the single species of the genus. The two micro-organisms shared 96.3 and 96.9 % 16S rRNA gene sequence similarity values with their nearest phylogenetic relative, J. dankookensis. The novel bacterial isolates were distinguished from J. dankookensis using biochemical tests. Based on both phenotypic and phylogenetic findings, it is proposed that the unknown bacteria be classified as representatives of two novel species of the genus Jeotgalibaca, Jeotgalibaca porci sp. nov. and Jeotgalibaca arthritidis sp. nov. The type strain of Jeotgalibaca porcisp. nov. is 1804-02T (=CECT 9156T=CCUG 69148T) and that of Jeotgalibaca arthritidissp. nov. is 1805-02T (=CECT 9157T=CCUG 69147T).
