Porphyromonas gingivalis is a keystone pathogen in periodontitis, a biofilm-mediated
infection disease. This research aimed to investigate the effect of coumarin on P. gingivalis …

The mitis group streptococci (MGS) are widespread in the oral cavity and are traditionally
associated with oral health. However, these organisms have many attributes that contribute …

Haemophilus parasuis (H. parasuis) is a kind of opportunistic pathogen of the upper
respiratory tract of piglets. Under certain circumstances, virulent strains can breach the …

ABSTRACT Porphyromonas. gingivalis (P. gingivalis) is an obligate, asaccharolytic, gram-
negative bacteria commonly associated with increased periodontal and systemic …

Although a variety of bacterial species have been reported to use the interspecies
communication signal autoinducer-2 (AI-2) to regulate multiple behaviors, the molecular …

Background Porphyromonas gingivalis, a periodontal pathogen, expresses a number of
virulence factors, including long (FimA) and short (Mfa) fimbriae as well as gingipains …

Biofilms play an important role in the development and pathogenesis of many chronic
infections. Oral biofilms, more commonly known as dental plaque, are a primary cause of …

The oral cavity contains more than 700 microbial species that are engaged in extensive cell–
cell interactions. These interactions contribute to the formation of highly structured …

Biofilm formation by the periodontal pathogen Aggregatibacter actinomycetemcomitans is
dependent upon autoinducer-2 (AI-2)-mediated quorum sensing. However, the components …

Iron is a nutrient that is indispensable for growth of almost all living organisms. The virulence
of pathogenic organisms in the mammalian host is related to the availability of iron …
