It is necessary to distinguish between pyogenic and tuberculous spondylitis of infectious spondylitis, if it is pyogenic spondylitis, antimicrobial therapy should be directed against an identified microorganism and clinical assessment should be done at 4 weeks. But if microorganism is a anaerobic bacteria, especially Peptostreptococcus anaerobius, combination antibiotic therapy should be considered bacause it may be a component of mixed infections as a passenger and have abilities to induce abscesses, other bacterial growth as a synergy effect. In addition, echocardiography may be necessary because pyogenic spondylitis is associated with infective endocarditis about 12%. We report a 64-year-old man who was treated for infectious spondylitis accompanied by Peptostreptococcus anaerobius bacteremia, but had to undergo heart surgery because an attack of infective endocarditis with systemic embolism during hospitalization.

2.The Growth Inhibition Effect on the Causative Bacteria of Bacterial Vaginosis by Bacterial Strains Isolated from the Vagina of a Healthy Woman.
Journal of Bacteriology and Virology 2014;44(3):244-251
Two Gram-positive rod strains isolated from the healthy vagina of a woman were tested for the possibility as probiotics. One strain was identified as Steroidobacter denitrificans (YH1) and the other as Lactobacillus crispatus (YH2) by 16S rRNA partial sequencing. The Casman agar and Man-Rogosa-Sharpe (MRS) agar were mixed in same quantity, supplemented with 5% human rbc lysate (CMB agar). The Wilkins-Chalgren agar and MRS agar were mixed in same quantity (WCM agar). Gardnerella vaginalis was cultured in Casman broth, supplemented with 5% human rbc lysate and 1,000 x-diluted with normal saline. Bacteroides fragilis, Mobiluncus mulieris and Peptostreptococcus asaccharolyticus were cultured in Wilkins-Chalgren anaerobe broth and 2,000x-diluted. S. denitrificans YH1 and L. crispatus YH2 were cultured in MRS broth anaerobically and 100x-diluted. The diluted suspensions of B. fragilis, M. mulieris and P. asaccharolyticus were inoculated on WCM agar and G. vaginalis on CMB agar by cotton swabs. Ten microl aliquots of YH1 and YH2 were inoculated on the center of WCM agar and CMB agar. The growth inhibition zone diameters of B. fragilis, G. vaginalis, M. mulieris and P. asaccharolyticus by YH1 were 35 mm, 35 mm, 25 mm and 60 mm. The inhibition diameters by YH2 were 25 mm, 30 mm, 20 mm and 40 mm, respectively. These results implicate that S. denitrificans YH1 can be the stronger probiotics for the treatment of bacterial vaginosis than L. crispatus, compared inhibition zone diameters by YH1 and YH2.

A gas forming brain abscess that was resistant to treatment with antibiotics, blycerol, and steroids is reported. A CT scan showed a frontal epidural gas shadow which progressed in 3 weeks to massive frontal cerebritis with gas within the abscess, ventricle, and basal cisterns. An anaerobic culture of CSF revealed peptostreptococus, which was been increasing recently as a causative organism in brain abscess. We feel that the primary management of brain abscess should be surgical excision followed by appropriate antibiotic therapy.

BACKGROUND AND OBJECTIVES: Infection of congenital preauricular fistula leads to preauricular abscess. Generally, the treatment for preauricular abscess is focused on subsiding abscess. Although incision & drainage is major point of therapy, the study of bacterial species and antibiotics for preauricular abscess is scant in literature. So, we investigated the most common species that cause preauricular abscess and the choice of proper antibiotics by using the databse available from the last 10 years. SUBJECTS AND METHOD: Our studies, from January, 2000 to December, 2010, included 86 patients in total (all in patients & out patients). We performed a retrospective review of bacterial species and culture analysis of each preauricular abscess. RESULTS: In this study, it was shown that most common pathogens causing preauricular fistula infection were Staphylococcus (27.9%), Enterococcus (9.3%), streptococcus and Klebsiella (5.8%) and Peptostreptococcus (4.6%). And Amoxicillin/cavulanate, Ciprofloxacin, Clindamycin had excellent effects of minimal inhibitory concentration through multiple pathogens. CONCLUSION: The choice of antibiotics for preauricular abscess will be targeted on Staphylococcus, Enterococcus, Streptococcus and anaerobic infection. Amoxicillin/clavulanate or Ciprofloxacin are the most effective antibiotics.

5.The Growth Inhibition Effect on the Bacterial Vaginosis Causative Bacteria by Citric Acid and Trisodium Phosphate.
Journal of Bacteriology and Virology 2015;45(3):228-234
Bacterial vaginosis (BV) is the most frequent vaginal disease being apt to relapse. The growth inhibition effect of the mixture of citric acid (CA) and trisodium phosphate (TSP) on BV causative bacteria and probiotics was measured. Gardnerella vaginalis was reduced to zero in WCCT-1 (CA 0.25% and TSP 0.55% in Wilkins-Chalgren broth), 2.0 x 10(4)/ml in WCCT-2 (CA 0.5% and TSP 0.8% in WC), and 3.3 x 10(3)/ml in WCCT-3 (CA 1.0% and TSP 2.6% in WC) comparing with 1.3 x 10(5)/ml in WC after 48 h. Bacteroides fragilis was reduced to 6.0 x 10(3)/ml in WCCA (CA 0.34% in WC), 2.3 x 10(2)/ml in WCCT (CA 0.5% and TSP 0.2% in WC), 7.0 x 10(3)/ml in WCHCl (HCl in WC) after 48 h. Mobiluncus mulieris was reduced to 1.08 x 10(4)/ml in WCCA, 1.03 x 10(3)/ml in WCCT, and 10 ea/ml in WCHCl after 48 h. Peptostreptococcus asaccharolyticus was completely inhibited in WCCA, WCCT, and WCHCl after 24 h. Probiotics, Steroidobacter denitrificans YH1 (3.4 x 10(7)/ml) and Lactobacillus crispatus YH2 (2.7 x 10(6)/ml), grew to 1.25 x 10(8)/ml and 2.6 x 10(7)/ml in MRSCA (CA 1.0% in MRS), 1.8 x 10(7)/ml and 4.6 x 10(6)/ml in MRSCT (CA 1.5% and TSP 0.58% in MRS), 1.2 x 10(8)/ml and 2.3 x 10(7)/ml in MRSHCl after 48 h, respectively. These results mean that the CA-TSP mixture can be used as the useful vaginal pH controller, growth inhibitor on BV causative bacteria, and an efficient means for settlement of probiotics.

Korean Journal of Urology 1994;35(6):640-645
In a general way, anaerobic isolation is troublesome and needs competent personnel and fittings. In addition, bacterial isolation from the prostate is disappointing because of difficulty in interpretation of the results. In this experiment, we tried the best way to isolate anaerobes from the prostate in terms of processing of the specimens such as catching, transportation, etc. We performed this antegrade experiment for 12 months in 1992 and got the results from 43 patients with chronic prostatitis syndrome as follows. l. Age distribution was in broad range between 20 and 54 showing peak incidence in 31-40 years(49% ) and the next in 20-30 years( 30%). 2. Subjective symptoms and signs consisted of perineal discomfort, suprapubic discomfort, frequency, urethral discomfort, dysuria, morning drop, testicular discomfort, and hemospermia 3. Majority of the cases( 36 cases. 83.7% ) were normal in the microscopy of VB1 EPS of 31 cases(72%) showed WBC more than 10/HPF. VB3 of 23 cases(53.5% ) showed than l0/HPF 4. A total of 40 cases showed aerobes in EPS and/or VB3 by culture. However, only 8 cases showed aerobes in EPS and/or VB, exclusive of 32 cases in which aerobes also appeared in VB1. 5. Anaerobic bacteria were cultured only from EPS for a total of 8 cases. There were 2 cases with Bacteroides species, 2 cases with Prevotella bivia, 2 cases with Peptostreptococcus anaerobrus,2 cases with Actinomyces meyeri, 1 case with Eubacterium lentum and 1 case with Eubacterium limosum.

The presence of distinct bacterial species is found to be dependent on age, diet, and disease. We compared the detection rate of several oral bacterial strains in a cohort of 36 subjects including healthy volunteers, periodontal patients, and oral cancer patients. Gargling samples were obtained from these subjects from which DNA was then extracted. Specific primers for 29 bacterial species were used for PCR detection. In the oral cancer patients, Capnocytophaga ochracea, Gemella morbillorum, and Streptococcus salivarius were detected more frequently compared with the healthy volunteers and periodontitis patients. Fusobacterium nucleatum/polymorphym and Prevotella nigrescens were significantly less prevalent in oral cancer patients than the other groups. In periodontitis patients, Porphyromonas gingivalis and Treponema denticola were more frequently found compared with the healthy volunteers. In the healthy volunteer group, Peptostreptococcus anaerobius was more frequently found than the other groups. The detection rate of several oral bacterial species was thus found to differ between healthy volunteers, periodontitis patients and oral cancer patients.

A 77-year-old woman presented with a trauma to the scalp caused from the blade of a windmill. The condition was persistent from the past 50 years. At the initial examination, a deep, foul-smelling and well-circumscribed ulcer was apparent on the head region, involving the majority of the cranium. Skin biopsy specimens of the lesion were nonspecific. The bone biopsy showed extensive necrotic areas of bone and soft tissues, with lymphocytic exudate foci. A computed tomography scan of the head revealed bone destruction principally involving both the parietal bones, and parts of the frontal and occipital bones. Streptococcus parasanguis was isolated from the skin culture, and Proteus mirabilis and Peptostreptococcus sp. were identified in the cultures from the bone. A long-term treatment with amoxicillin-clavulanic acid (1 g/12 h) and levofloxacin (500 mg/day) was prescribed, but even after 6 months, the lesion remained unchanged. The frequency of occurrence of scalp ulcers in dermatological patients is less, principally because of the rich blood supply to this area. We have not found any similar case report of a scalp ulcer secondary to chronic osteomyelitis discovered more than 50 years after the causal trauma. We want to highlight the importance of complete cutaneous evaluation including skin and bone biopsies, when scalp osteomyelitis is suspected.

Parvimonas micra is a non-spore-forming anaerobic gram-positive coccus, widely distributed as normal flora in the skin, vagina and mucosa, and able to cause opportunistic infections, particularly endocarditis and brain abscess following dental manipulations. A 49-year-old woman was hospitalized due to fever and headache. She had been diagnosed with periodontitis at the beginning of fever. A brain abscess was noted in the right temporal lobe on the brain CT, and she was treated with ceftriaxone, isepamicin and metronidazole. In the next day, abscess was aspirated and drained by a surgical procedure. An organism was isolated from an anaerobic culture of the abscess aspirate, and was identified as P. micra by a commercial kit and 16S rRNA sequencing.

Journal of Rhinology 2006;13(2):107-114
BACKGROUND AND OBJECTIVES: Microbiologic data in chronic sinusitis with nasal polyps, which is the foundation of proper antibiotic treatment, is insufficient due to problems with sampling and culture technique. Therefore, the objective of this study is to identify the causative agents in chronic sinusitis with nasal polyps based on culture results in adults and children and the relationship between the results of the middle meatus and maxillary sinus. Materials and Method: Samples were obtained with middle meatus swabs and endoscopically guided maxillary sinus aspirations and then transferred to a microbiology laboratory using different media for aerobic and anaerobic cultures. RESULTS: Eighty one samples were studied. Sixty six from the middle meatus and sixty four from the maxillary sinus bacterial isolates were recovered. The most frequently isolated aerobic organisms were the Staphylococcus, Haemophilus influenza and Streptococcus while those of the anaerobic organisms in adults were the Prevotella and Peptostreptococcus. No anaerobic microorganisms were isolated in the children. Concordance rates of aerobic bacteria were 75.4% among adults and 90.0% among children. That of anaerobic bacteria was 83.6% among adults and 100% among children between the middle meatal swab and the maxillary sinus aspiration. CONCLUSION: Authors recommend amoxacillin/clavulanate, cephalosporins and macrolide as the first-line medical treatment. In cases where there are no improvement of symptoms, cultures should be taken from the middle meatus, followed by appropriate selection of second-line antibiotics according to the sensitivity test results.
