The activity of trovafloxacin and five other oral agents against 250 aerobic and 137 anaerobic strains isolated from human and animal bite wounds was determined by an agar dilution method. Trovafloxacin was active against all aerobic and fastidious facultative isolates at < or = 0.5 mg/L and all anaerobes at < or = 2 mg/L (Bacteroides tectum, Porphyromonas salivosa and Prevotella heparinolytica...

Despite the high incidence of odontogenic abscesses in pet rabbits, published data on the bacteriology of these infections are lacking, and clinical cultures are often ambiguous, making antibiotic choices difficult. In order to define the bacteriology of these infections, 12 rabbit mandibular and maxillary abscesses were cultured aerobically and anaerobically. All specimens yielded pathogenic b...

We investigated the influence of gut microbiotal metabolism on the pharmacokinetics of berberine in healthy male Africans and Chinese. The Cmax and AUC in the Africans were 2.67-fold and 2.0-fold higher than the Chinese, respectively. Microbiotal compositions by 16S rRNA pyrosequencing showed higher abundance of the genera Prevotella, Bacteroides, and Megamonas (34.22, 13.88, and 10.68%, respec...

Contrary to the common assumption that food has a negative impact on oral health, research has shown that several foods contain a number of components with antibacterial and antiplaque activity. These natural compounds may be useful for improving daily oral hygiene. In this study we evaluate the mode of antimicrobial action of fractions of mushroom and red chicory extracts on Prevotella interme...

Lipopolysaccharide (LPS) preparations from gram-negative black-pigmented bacteria such as Porphyromonas gingivalis and Prevotella intermedia activate cells from non-LPS-responsive C3H/HeJ mice, but it is still unclear whether this activity is due to the unique structure of LPS or to a minor component(s) responsible for the activity in the preparation. A nonendotoxic glycoprotein with bioactivit...

Fluoretec, a commercial kit for the rapid diagnosis by immunofluorescence of infections caused by Bacteroides spp was compared with a standard culture method. A total of 1010 specimens were tested for the presence of B fragilis group by Fluoretec F and B melaninogenicus-oralis and asaccharolytic groups by Fluoretec M. Fluoretec F was positive in 123/152 specimens culturing B fragilis group stra...

Background & Aim Sarcopenia is frequent in cirrhosis and associated with unfavourable outcomes. The role of the gut-liver-muscle axis this setting has been poorly investigated. aim study was to identify gut microbiota, metabolic inflammatory signatures sarcopenia cirrhotic patients. Methods Fifty patients assessed for presence by quantification muscle mass strength were compared age- sex-matche...

Periodontal disease comprises mild to severe inflammatory host responses to oral bacteria that can cause destruction of the tooth-supporting tissue. We report genome sequences for 18 clinical isolates of Porphyromonas gingivalis, Prevotella intermedia, and Tannerella forsythia, Gram-negative obligate anaerobes that play a role in the periodontal disease process.

The aim of the present study was to assess the application of monoclonal antibodies to the detection of black-pigmented Bacteroides spp. in subgingival plaques by immunoslot blot assay. Subgingival plaque samples from adult periodontal patients were examined by immunoslot blot assay with monoclonal antibodies that specifically recognize Bacteroides gingivalis, Bacteroides intermedius serogroups...

Prevotella nigrescens ATCC 25261 cells adhere well to protein-blocking hydroxyapatite (HA) which mimics a root surface in the periodontal pocket treated with proteases such as trypsin, proteinase K, chymotrypsin and papain. This study was done to clarify the inhibitory effect of alpha- and beta- serum globulins on the adhesion of P. nigrescens ATCC 25261 cells to trypsin-treated HA. The inhibit...
