Deciphering the role of the opportunistic pathogen Bacillus pumilus and Streptococcus uberis in bovine postpartum uterine infections

A Gram-stain-positive bacterial isolate, designated LMM-1652T, was isolated from an intrauterine cytobrush sample originating from a postpartum Holstein Friesian dairy cow. The strain had a rod to coccoid-shape, was catalase-positive and oxidase-negative. 16S rRNA gene sequence similarity analyses revealed that its closest relatives were Corynebacterium falsenii (97.05 % similarity), Corynebacterium jeikeium (96.83 %) and Corynebacterium urealyticum (96.82 %). Subsequent whole genome analysis showed that the genome-to-genome distance of strain LMM-1652T to its closest relatives was in the range of 23.2-24.8 %, while the average nucleotide identity values ranged from 73.7 to 74.3%, thus confirming that this isolate represents a novel species. Strain LMM-1652T was characterized by a quinone system mainly consisting of MK-9(H2) and MK-10(H2). The polar lipids profile of the strain consisted mainly of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol-mannoside, as well as one unidentified lipid lacking any functional group. Smaller amounts of four unidentified phospholipids, four unidentified glycolipids, β-gentiobiosyl diacylglycerol and four unidentified lipids lacking a functional group were also found. The cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid of the peptidoglycan. The fatty acid profile was mainly composed of C18 : 1 ω9c, C18 : 0 and C16 : 0. We propose a novel species of the genus Corynebacterium with the name Corynebacterium urogenitale LMM-1652T (=LMG 31163T=DSM 108747T).
