Abstract/Summary

Nineteen strains of Gram-positive, non-motile, non-spore-forming, catalase-positive, rod-shaped bacteria isolated from pigs were characterized by using biochemical, molecular chemical and molecular genetic methods. Two distinct groups of organisms were discerned, based on their colonial morphology, CAMP (Christie-Atkins-Munch-Petersen) reaction and numerical profile by using the API Coryne system. The first group (113 strains) gave a doubtful discrimination between Corynebacterium striatum and Corynebacterium amycolatum, whilst the second group (six strains) were identified tentatively as Corynebacterium urealyticum. Comparative 16S rRNA gene sequencing studies demonstrated that all of the isolates belonged phylogenetically to the genus Corynebacterium. The first group of organisms was highly similar to Corynebacterium testudinoris with respect to 16S rRNA gene sequences and physiological characteristics, whereas the remaining six isolates formed a hitherto unknown subline within the genus, associated with a small subcluster of species that included Corynebacterium auriscanis and its close relatives. The unknown Corynebacterium sp. was distinguished readily from these and other species of the genus by biochemical tests. Based on both phenotypic and phylogenetic evidence, it is proposed that the new isolates from pigs should be classified as a novel species, Corynebacterium suicordis sp. nov. The type strain is P81/02(T) (=CECT 5724(T) =CCUG 46963(T)).
