Abstract

Abstract Strains Marseille-P3761 and Marseille-P3195 are representatives of two bacterial species isolated from human specimens. Strain Marseille-P3761 was isolated from the stool of a healthy volunteer, while strain Marseille-P3915 was cultivated from the urine of a kidney transplant recipient. Both strains are anaerobic Gram-positive coccoid bacteria. Both are catalase-negative and oxidase-negative and grow optimally at 37 °C in anaerobic conditions. They also metabolize carbohydrates, such as galactose, glucose, fructose, and glycerol. The major fatty acids were hexadecanoic acid for both strains. The highest digital DNA–DNA hybridization (dDDH) values of Marseille-P3761 and Marseille-P3195 strains when compared to their closest phylogenetic relatives were 52.3% and 56.4%, respectively. Strains Marseille-P3761 and Marseille-P3195 shared an OrthoANI value of 83.5% which was the highest value found with Peptoniphilus species studied here. The morphological, biochemical, phenotypic and genomic characteristics strongly support that these strains are new members of the Peptoniphilus genus. Thus, we suggest that Peptoniphilus coli sp. nov., and Peptoniphilus urinae sp. nov., are new species for which strains Marseille-P3761 (CSUR P3761 = CCUG 71,569) and Marseille-P3195 (CSUR P3195 = DSM 103,468) are their type strains, respectively of two new Peptoniphilus species, for which we propose the names Peptoniphilus coli sp. nov. and Peptoniphilus urinae sp. nov., respectively.
