| the bacteriology of salivary gland infections. | the parotid gland is the salivary gland most commonly affected by inflammation. however, infection of the salivary glands can occur in any of the glands. the most common pathogens associated with acute bacterial infection are staphylococcus aureus and anaerobic bacteria. the predominant anaerobes include: anaerobic gram negative bacilli (eg, pigmented prevotella and porphyromonas); fusobacterium spp; and peptostreptococcus spp. in addition, streptococcus spp (including streptococcus pneumoniae) ... | 2009 | 19608044 |
| effect of age on gingival crevicular fluid concentrations of mif and pge2. | we used an experimental gingivitis study design to compare crevicular fluid concentrations of migration inhibitory factor (mif) and prostaglandin e(2) (pge(2)) in younger (18 to 30 yrs) and older (46 to 77 yrs) healthy adults. pge(2) increased after 1 wk in younger participants, whereas it decreased in older individuals after 1 wk of plaque accumulation. a significant interaction between age and time was observed for pge(2) (p = 0.04). high concentrations of mif were identified in both age group ... | 2009 | 19641151 |

| identification of a mechanical rheostat in the hydrophobic core of protein l. | the ability of proteins and their complexes to withstand or respond to mechanical stimuli is vital for cells to maintain their structural organisation, to relay external signals and to facilitate unfolding and remodelling. force spectroscopy using the atomic force microscope allows the behaviour of single protein molecules under an applied extension to be investigated and their mechanical strength to be quantified. protein l, a simple model protein, displays moderate mechanical strength and is t ... | 2009 | 19683005 |
| the ability of non-bacteriocin producing streptococcus bovis strains to bind and transfer bovicin hc5 to other sensitive bacteria. | streptococcus bovis hc5 produces a broad spectrum lantibiotic (bovicin hc5), but s. bovis jb1 does not have antimicrobial activity. preliminary experiments revealed an anomaly. when s. bovis jb1 cells were washed in stationary phase s. bovis hc5 cell-free culture supernatant, the s. bovis jb1 cells were subsequently able to inhibit hyper-ammonia producing ruminal bacteria (clostridium sticklandii, clostridium aminophilum and peptostreptococcus anaerobius). other non-bacteriocin producing s. bovi ... | 2009 | 19171197 |

| mechanical characterization of protein l in the low-force regime by electromagnetic tweezers/evanescent nanometry. | mechanical manipulation at the single molecule level of proteins exhibiting mechanical stability poses a technical challenge that has been almost exclusively approached by atomic force microscopy (afm) techniques. however, due to mechanical drift limitations, afm techniques are restricted to experimental recordings that last less than a minute in the high-force regime. here we demonstrate a novel combination of electromagnetic tweezers and evanescent nanometry that readily captures the forced un ... | 2009 | 19413987 |

| targeted antimicrobial activity of a specific igg-smap28 conjugate against porphyromonas gingivalis in a mixed culture. | antimicrobial peptides coupled to a ligand, receptor or antibody for a specific pathogenic bacteria could be used to develop narrow-spectrum pharmaceuticals with 'targeted' antimicrobial activity void of adverse reactions often associated with the use of broad-spectrum antibiotics. to assess the feasibility of this approach, in this study sheep myeloid antimicrobial peptide (smap) 28 was linked to affinity- and protein g-purified rabbit immunoglobulin g (igg) antibodies specific to the outer sur ... | 2009 | 18778918 |
| pericarditis caused by anaerobic bacteria. | this review describes the microbiology, diagnosis and management of pericarditis due to anaerobic bacteria. the predominant anaerobes isolated from patients with pericarditis are gram-negative bacilli (mostly bacteroides fragilis group) as well as peptostreptococcus, clostridium, fusobacterium, bifidobacterium and actinomyces spp. anaerobic bacteria can be recovered from pericarditis resulting from the following mechanisms: (i) spread from a contiguous site of infection, either de novo or follow ... | 2009 | 18789852 |
| uncultivated bacteria as etiologic agents of intra-amniotic inflammation leading to preterm birth. | intra-amniotic infection and inflammation are major causes of preterm birth (ptb). however, intra-amniotic inflammation is often detected in the absence of infection. this may partly be due to the culturing methods employed in hospital laboratories, which are unable to detect the uncultivated species. in this study, intra-amniotic microbial infections associated with ptb were examined by both culture and 16s rrna-based culture-independent methods and were corroborated by the presence of intra-am ... | 2009 | 18971361 |

| the microbiota of acute apical abscesses. | as the breadth of bacterial diversity in the oral cavity has been deciphered by molecular studies, several newly identified species/phylotypes have emerged as potential pathogens. we hypothesized that many of these species/phylotypes could also be involved with the etiology of endodontic abscesses. abscess aspirates from 42 persons were analyzed for the presence of 81 species/phylotypes by means of a reverse-capture checkerboard hybridization assay. associations between the most frequently detec ... | 2009 | 19131319 |
| clinical and microbiological determinants of ailing dental implants. | the failure of the host tissue to establish or maintain osseointegration around dental implants is due to either occlusal or parafunctional forces, premature loading, ill-directed stress, or microbial infection. the long-term failure rate of dental implants is generally 5-10%. although a variety of etiologies of early peri-implant bone loss (from implant placement to 1-year post-loading) have been proposed, factors associated with late implant failures are less well understood but are probably r ... | 2009 | 18384407 |
