Maternal periodontal infection has been recognized as a risk factor for preterm and low birthweight infants. It is suspected that pathogens causing periodontal disease may translocate to the amniotic cavity and so contribute to triggering a...
Aggregatibacter actinomycetemcomitans leukotoxin is post-translationally modified by addition of either saturated or hydroxylated fatty acyl chains [0.03%]
Aggregate放线体共生菌白细胞毒素通过添加饱和或羟基脂肪酰链进行翻译后修饰
K P Fong,H-Y Tang,A C Brown et al.
K P Fong et al.
Aggregatibacter actinomycetemcomitans, a common inhabitant of the human upper aerodigestive tract, produces a repeat in toxin (RTX), leukotoxin (LtxA). The LtxA is transcribed as a 114-kDa inactive protoxin with activation being achieved by...
Live/dead real-time polymerase chain reaction to assess new therapies against dental plaque-related pathologies [0.03%]
实时聚合酶链反应检测牙菌斑相关病害的新疗法的效果
G Loozen,N Boon,M Pauwels et al.

DNA-based methodology for the identification and detection of specific bacteria in dental plaque offers advantages over culturing techniques. One drawback of current molecular techniques like real-time quantitative polymerase chain reaction...
In situ analysis of multispecies biofilm formation on customized titanium surfaces [0.03%]
定制钛表面多物种菌膜形成的原位分析
V Fröjd,L Chávez de Paz,M Andersson et al.
V Fröjd et al.
Many studies to identify surfaces that enhance the incorporation of dental implants into bone and soft-tissue have been undertaken previously. However, to succeed in the clinical situation, an implant surface must not support development of...
Synergistic virulence of Porphyromonas gingivalis and Treponema denticola in a murine periodontitis model [0.03%]
牙龈卟啉单胞菌和齿密螺旋体在小鼠牙周炎模型中的协同致病性
R K-H Orth,N M O&#x;Brien-Simpson,S G Dashper et al.
R K-H Orth et al.
Chronic periodontitis is characterized by the destruction of the tissues supporting the teeth and has been associated with the presence of a subgingival polymicrobial biofilm containing Porphyromonas gingivalis and Treponema denticola. We h...
Streptococcus anginosus l-cysteine desulfhydrase gene expression is associated with abscess formation in BALB/c mice [0.03%]
变型链球菌半胱氨酸脱硫酶基因表达与BALB/c小鼠脓肿形成的关系研究
Y Takahashi,A Yoshida,E Nagata et al.
Y Takahashi et al.
Streptococcus anginosus, an anginosus group bacterium, is frequently isolated from odontogenic abscesses, and is the oral bacterium that is primarily responsible for producing hydrogen sulfide from l-cysteine through the action of its l-cys...
B C Dickinson,C E Moffatt,D Hagerty et al.
B C Dickinson et al.
Primary gingival epithelial cells were cultured in multilayers as a model for the study of interactions with oral bacteria associated with health and periodontal disease. Multilayers maintained at an air-liquid interface in low-calcium medi...
Characterization of antigen-presenting cells induced by intragastric immunization with recombinant chimeric immunogens constructed from Streptococcus mutans AgI/II and type I or type II heat-labile enterotoxins [0.03%]

Streptococcus mutans strains recovered from caries-active or caries-free individuals differ in sensitivity to host antimicrobial peptides [0.03%]
从龋齿活跃或无龋个体中分离的变异链球菌菌株对宿主抗菌肽的敏感性不同
E Phattarataratip,B Olson,B Broffitt et al.
E Phattarataratip et al.
Antimicrobial peptides (AMPs) are among the repertoire of host innate immune defenses. In the oral cavity, several AMPs are present in saliva and have antimicrobial activities against oral bacteria, including Streptococcus mutans, a primary...
