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...

Prevotella is one of the most abundant genera in bovine rumen, although no genome has yet been assembled by a metagenomics approach applied to Brazilian Nelore. We report the draft genome sequence of Prevotella sp., comprising 2,971,040 bp, obtained using the Illumina sequencing platform. This genome includes 127 contigs and presents a low 48% GC.

BACKGROUND In a series of studies of the gut microbiome, "enterotypes" have been used to classify gut microbiome samples that cluster together in ordination analyses. Initially, three distinct enterotypes were described, although later studies reduced this to two clusters, one dominated by Bacteroides or Clostridiales species found more commonly in Western (American and Western European) subjec...

Members of the genera Bacteroides, PrevoteUa, and Porphyromonas were investigated for their glucose 6-phosphate dehydrogenase (G6PDH) and 6-phosphogluconate dehydrogenase (6PGDH) activities by using spectrophotometric (SP) and alloenzyme elecrophoresis (AE) detection methods. When the SP and AE methods were compared, the AE method failed to detect activity in two of the six strains which exhibi...

Transport media should preserve the viability and stability of microorganisms in clinical specimens. In this study, the Port-A-Cul transport system and the Copan transport system without charcoal, both designed to preserve anaerobes, were evaluated. Dacron swabs were inoculated with two combinations of facultative and anaerobic organisms typically found in vaginal swab samples. Combination I co...
