Pelistega suis sp. nov., isolated from domestic and wild animals
Investigation published in International Journal of Systematic and Evolutionary Microbiology
December 1st, 2015
Biochemical and molecular genetic studies were performed on three novel Gram-stain-negative, catalase, oxidase-positive bacilli-shaped organisms isolated from tonsils of two pigs and one wild boar. The microorganism was identified as a species associated with the genus Pelistega based on its cellular morphological and biochemical tests. On the basis of 16S rRNA gene sequence similarities, isolates were most closely related to Pelistega indica (98.2%). groEL and gyrB sequence analysis showed interspecies divergence from its closest 16S rRNA phylogenetic relative, P. indica of 87.0% and 69%, respectively. The polyamine pattern contains predominantly putrescine and 2-hydroxyputrescine. The major quinone is ubiquinone Q-8 and in the polar lipid profile phosphatidylethanolamine, phosphatidylglycerol, an unidentified aminolipid and an unidentified lipid not containg a phosphate residue, an amino- or a phosphate-group are predominating. The novel bacterial isolate can be distinguished from P. indica by several biochemical characteristics, such as the production of L-pyrrolydonil arylamidase and gamma-glutamyl-transferase and utilization of different carbon sources. Based on both phenotypic and phylogenetic findings, it is proposed that the novel bacterium be classified as a new species of the genus Pelistega, Pelistega suis sp. nov. The type strain of Pelistega suis is 3340-03T (= CECT 8400T = CCUG 64465T)
