Cutibacterium acnes is a member of normal flora of human skin, conjunctiva, intestinal tract, the external auditory canal as well as oral cavity. It has been identified as an opportunistic pathogen related to acne vulagris, endocarditis infections, sarcoidosis, brain abscess, periodontitis, and osteomyelitis of the humerus. C. acnes KCOM 1315 (= ChDC KB81) was isolated from a human jaw osteomyelitis lesion. Here, we present the complete genome sequence of C. acnes KCOM 1315.

Cutibacterium acnes is Gram-positive, anaerobic, aerotolerant, diphtheroid, and rod-shaped bacterium. C. acnes is a member of normal flora of human skin, conjunctiva, intestinal tract, the external auditory canal as well as oral cavity (McDowell et al., 2013; Scholz and Kilian, 2016; Aubin et al., 2017). It has been reported that C. acnes was identified as an opportunistic pathogen related to acne vulgaris (Leyden, 2001), endodontic infections (Niazi et al., 2016), endocarditis (Günthard et al., 1994), sarcoidosis (Zhou et al., 2013), periodontitis (Narita et al., 2016), brain abscess (Zaffiri et al., 2013), and osteomyelitis of the humerus (Sainani et al., 2015). C. acnes KCOM 1315 (= ChDC KB81) was isolated from a human jaw osteomyelitis lesion. In this report, we present the complete genome sequence of C. acnes KCOM 1315.

The C. acnes KCOM 1315 was grown on tryptic soy agar (TSA; BD Difco Laboratories) supplemented with 5% sheep blood in an anaerobic chamber (Model Bactron I) maintained using a gas mixture of 10% H2, 5% CO2, and 85% N2. The bacterial genomic DNA was prepared as previously described (Cho et al., 2015).

The genomic DNA of C. acnes KCOM 1315 was sequenced using PacBio RSII SMRT sequencing platform using a 20 kb SMRTbell template library and Illumina HiSeq 2500 by Macrogen Inc. Approximately 1,509 Mb (589 ×) with 181,833 filtered subreads (mean subreads length 8,302 bp) were generated and assembled into a single contig by HGAP (version: 3.0, default setting) in PacBio’s SMRT portal ( The initial assembly was polished by Pilon (version: 1.21) with 13,154,086 paired-end reads (518 ×, trimmed by trimmomatic 0.36) from Illumina Hiseq 2500 ( (Walker et al., 2014). The pilon fixed 33 INDELs and most of errors were A/T insertions or G/C deletions. Genome annotation was conducted by the NCBI Prokaryotic Genome Annotation Pipeline (PGAP) ( (Tatusova et al., 2016).

The complete genome of C. acnes KCOM 1315 was 2,560,301 bp in length and had a G+C content of 60.0%. A total of 2,368 protein-coding sequences (CDSs), 9 rRNAs, and 47 tRNAs were annotated (Table 1 and Fig. 1).

Circular map of genome of Cutibacterium acnes KCOM 1315. Marked characteristics are shown from outside to the center; CDS on forward strand, CDS on reverse strand, tRNA, rRNA, GC content, and GC skew.

The genome sequence contained antibiotic-resistance-related genes; macrolide export ATP-binding/permease protein MacB, multiple antibiotic resistance protein MarR/MdtG, metallo- beta-lactamase type 2, multidrug resistance protein Stp, putative multidrug resistance ABC transporter ATP-binding/permease protein YheI, putative multidrug-efflux transporter, and multidrug efflux protein YfmO. It contained several protease genes; ATP- dependent zinc metalloprotease FtsH, tricorn protease, zinc metalloprotease Rip1, Lon protease, extracellular basic protease, rhomboid protease AarA, putative zinc protease, periplasmic serine endoprotease DegP, serine protease, and protease Hflk. The genome encoded for involving the biofilm formation, putative glycosyltransferase EpsJ and biofilm regulatory protein A. The genome contained the oxidative stress-response genes such as superoxide dismutase (Mn/Fe), thioredoxin-2, catalase, thioredoxin reductase, and thiol-disulfide oxidoreductase ResA. The genome also contained the two-component systems (MtrB/ MtrA and VraR/LiaS). Hemolysin C, diphtheria toxin repressor, hemolysin C, antitoxin YqcF, and putative antitoxin VapB12, putative sialic acid transporter and outer membrane porin F were founded in the genome sequence.

The C. acnes KCOM 1315 strain was deposited into the Korean Collection for Oral Microbiology.
