The strains grew best under aerobic conditions with 5 % CO2 and colonies were non-haemolytic and greyish-white. They were non-motile and negative for catalase and oxidase. The genomes of the four strains 19M2397T, 15A0121, 15IMD0307 and 19OD0592 were obtained by sequencing. The results of phylogenetic analyses based on the 16S rRNA gene grouped them within the genus Trueperella in the family Arcanobacteriaceae . The genomes had DNA G+C contents of 61.2–62.2 mol% and showed digital DNA–DNA hybridization (dDDH) values of 21.4–22.8 % and average nucleotide identity (ANI) values of approximately 77 % to their closest relatives Trueperella pyogenes and Trueperella bernardiae . With respect to the presence in different livestock species we propose the name Trueperella pecoris sp. nov. The type strain is 19M2397T (=CCOS 1952T=DSM 111392T), isolated from the udder secretion of a heifer diagnosed with summer mastitis in 2019., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.004848
