Parvimonas micra is a Gram-positive, obligately anaerobic, non-spore forming, and non-motile cocci. P. micra is a member of oral flora and is associated with oral, respiratory, and gastrointestinal tract infections. Parvimonas micra KCOM 1535 (=ChDC B708) was isolated from a human periapical abscess lesion. Here, we present the complete genome sequence of P. micra KCOM 1535.

Acute osteomyelitis caused by Klebsiella pneumoniae is rare in the oral and maxillofacial region. Klebsiella pneumoniae is a Gram-negative bacillus and the normal flora of the human body, but it can cause pneumonia, urinary tract infection, meningitis, and osteomyelitis in patient with compromised immune systems. These infections are mainly caused by nosocomial infection. Microbacterial osteomyelitis was developed by clinical cause such as tooth extraction, fracture, and surgical history, which requires long-term antibiotic administration and surgical treatment. This report describes that a 56-year-old male patient with acute osteomyelitis caused by Klebsiella pneumoniae infection after implant placement was treated with intravenous administration of ertapenem without open surgery treatment. Through this case, we report that antibiotic susceptibility test is essential for the treatment of acute osteomyelitis caused by a bacterial infection resistant to empirical antibiotics, and early administration of appropriate antibiotics can reduce the possibility of extensive bone destruction or additional open surgery.

Parvimonas micra is Gram-positive, strict anaerobic, non-motile, and non-spore forming coccus. It is a member of oral flora and is related to oral infectious diseases as well as systemic diseases. P. micra KCOM 1037 (= ChDC B276) was isolated from human postoperative maxillary cyst lesion. Here, we present the complete genome sequence of P. micra KCOM 1037.

Fusobacterium animalis (formerly Fusobacterium nucleatum subsp. animalis) is a Gram-negative, anaerobic, and filament-shaped bacterium. F. animalis may be a part of normal flora and a periodontopathogen of human oral cavity. F. animalis KCOM 1280 (= ChDC F318) was isolated from a human periodontitis lesion. In this report, we present the draft genome sequence of F. animalis KCOM 1280.

Streptococcus intermedius is a Gram-positive, obligately anaerobic, nonsporeforming, and nonmotile cocci. S. intermedius is a member of oral flora and is endodontic infection, respiratory infections, infective endocarditis, brain abscess, and liver abscess. Streptococcus intermedius ChDC B718 (= KCOM 1545) was isolated from a human pulpitis lesion. Here, we present the complete genome sequence of S. intermedius ChDC B718.

Recently, Fusobacterium nucleatum subsp. vincentii was reclassified as Fusobacterium vincentii based on the average nucleotide identity and genome-to-genome distance analyses. F. vincentii is a Gram-negative, anaerobic, and filament-shaped bacterium. F. vincentii is a member of normal flora of human oral cavity and plays a role in periodontal diseases. F. vincentii KCOM 2931 was isolated from a periodontitis lesion. Here, we present the complete genome sequence of F. vincentii KCOM 2931.

Recently, Fusobacterium nucleatum subsp. polymorphum was reclassified as Fusobacterium polymorphum based on the average nucleotide identity and genome-to-genome distance analyses. F. polymorphum is a Gram-negative, anaerobic, and filament-shaped bacterium. F. polymorphum is a part of normal flora of oral cavity and causative agent of periodontal diseases. F. polymorphum KCOM 1001 (= ChDC F119) was isolated from a human subgingival plaque of gingivitis lesion. Here, we present the complete genome sequence of F. polymorphum KCOM 1001.

Actinomycosis is defined as a chronic, specific, suppurative, granulomatous disease caused mainly by the anaerobic, gram positive organism, Actinomyces israelii. Actinomycosis in the salivary gland is a rare disease that is caused by an inhabitant of the normal flora. We report the case of the actinomycosis of submandibular gland. A 53-year old man presented with the swelling on left submandiblar area. The lesion was not painful but had been increasing for about 10 days. In the CT view, the internal portion of the mass showed homogeneous moderate signal. The mass had continuities with the inferior portion of the left enlarged submandibular gland. In the MRI, there was a mass that showed a buldging pattern inferiorly in the left submandibular gland without bony invasion sign. The biopsy shows the colony of special organism. Many filaments are discovered with clubbed ends diffused from center of colony. We diagnosed this disease as actinomycosis in the submandibular gland by the postoperational biopsy.

Cutibacterium acnes (formerly Propionibacterium acnes) is an anaerobic, Gram-positive rod and that is a normal flora of human skin and mucosal surface as well as an opportunistic pathogen related to acnes vulgaris, sarcoidosis, brain abscess, endocarditis, periodontitis, and endodontic infections. C. acnes KCOM 1861 (= ChDC B594) was isolated from a human jaw osteomyelitis lesion. Here, we present the complete genome sequence of C. acnes KCOM 1861.
