The lipids of Bacteroides melaninogenicus were readily extractable with chloroform-methanol. Three per cent of the fatty acids were not extractable. The neutral lipids contained 4% of the extractable fatty acids, the stench characteristic of these organisms, and 0.5 mumole of vitamin K(2) isoprenologues K(2)-35, K(2)-40, and K(2)-45 per g (dry weight). This is one-fifth to one-tenth of the vita...
Prevotella multisaccharivorax Sakamoto et al. 2005 is a species of the large genus Prevotella, which belongs to the family Prevotellaceae. The species is of medical interest because its members are able to cause diseases in the human oral cavity such as periodontitis, root caries and others. Although 77 Prevotella genomes have already been sequenced or are targeted for sequencing, this is only ...
This paper describes a quantitative fluorescent in situ hybridization (FISH) assay for the differential identification of Prevotella intermedia and Prevotella nigrescens in clinical samples, and compares its performance with less discriminatory culture and quantitative immunofluorescence (IF) assays. Fluorescence-labelled oligonucleotide probes directed to specific 16S rRNA sequences of P. inte...
We describe a new PCR-based method for distinguishing human and cow fecal contamination in coastal waters without culturing indicator organisms, and we show that the method can be used to track bacterial marker sequences in complex environments. We identified two human-specific genetic markers and five cow-specific genetic markers in fecal samples by amplifying 16S ribosomal DNA (rDNA) fragment...
OBJECTIVES To compare the antimicrobial susceptibility of Prevotella spp. isolated from cystic fibrosis (CF) and non-CF patients and analyse the impact of antibiotic prescribing in the preceding year on resistance amongst CF isolates. METHODS The susceptibility of 80 CF Prevotella isolates to 12 antibiotics was compared with that of 50 Prevotella isolates from invasive infections in people wh...
We report a case of a 75 year-old man who was diagnosed with a L3-L4 spondylitis with psoas abscess documented at Prevotella denticola. However, the dental origin of the bacteria, the presence of the spondylitis, and the identification on an aneurysm of the inter-atrial septum with a patent oval foramen and finally the metabolic activity of the aortic valve and teeth revealed by 18FFDG PET/ CT ...
BACKGROUND Members of the genera Prevotella, Veillonella and Fusobacterium are the predominant culturable obligate anaerobic bacteria isolated from periodontal abscesses. When determining the cumulative number of clinical anaerobic isolates from periodontal abscesses, ambiguous or overlapping signals were frequently encountered in 16S rRNA gene sequencing chromatograms, resulting in ambiguous i...
conclusions in conclusion, in spite of usually benign features, chronic otitis media may lead to serious complications such as brain abscess. every effort should be made for microbiological diagnosis of the causative pathogen(s) for appropriate antibiotic treatment. introduction brain abscess is a rare life-threatening focal intracerebral infection. the etiology of brain abscess depends on trau...
