OBJECTIVES To investigate mechanisms of reduced susceptibility to commonly used antibiotics in Prevotella cultured from patients with cystic fibrosis (CF), patients with invasive infection and healthy control subjects and to determine whether genotype can be used to predict phenotypic resistance. METHODS The susceptibility of 157 Prevotella isolates to seven antibiotics was compared, with det...

Propolis extract antimicrobial activity against periodontopathic (ATCC) bacteria was investigated “in vitro”. Bacterial strains tested were: Prevotella intermedia, Prevotella melaninogenica, Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans, Capnocytophaga gingivalis and Fusobacterium nucleatum. Minimal inhibitory concentration (MIC) for the strains tested was determined using the ...

The AB Biodisk Etest showed that 106 (100%) and 98 (92%) isolates of Eikenella corrodens were susceptible to amoxicillin and tetracycline, respectively. Twenty-three (68%) Prevotella intermedia isolates and 14 (67%) Prevotella nigrescens isolates were susceptible to amoxicillin. Seventy-nine percent of the P. intermedia isolates and 67% of the P. nigrescens isolates were susceptible to tetracyc...

The glutamate dehydrogenase (GDH) activities for the type strains of Prevotella ruminicola (strain 23), Prevotella brevis (strain GA33), and Prevotella bryantii (strain B(1)4) were assessed by a combination of enzyme assays and analysis of migration patterns of GDH proteins following nondenaturing polyacrylamide gel electrophoresis. Unlike results with most other prokaryotes, but similar to res...

Resistance in streptococci or Gram-negative bacteria is associated with antibiotic consumption. Scarce information exists on the antibiotic susceptibility of bacterial isolates from patients with periodontitis in countries with high antibiotic consumption, as this is an area in which microbiological testing is not performed in daily practice. The present study was undertaken to explore the susc...

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...
