Actinomycosis is a chronic and less common infectious process that established by Actinomyces israilii. Involvement of faciocervical region is more common than thorasic and visceral types and typically involves the angle of mandible and with less occurrence rate the upper jaw may also be involved. Periapical lesions of maxilla that involved in this process by Actinomyces israilii are rare and c...

Streptococci and actinomyces that initiate colonization of the tooth surface frequently coaggregate with each other as well as with other oral bacteria. These observations have led to the hypothesis that interbacterial adhesion influences spatiotemporal development of plaque. To assess the role of such interactions in oral biofilm formation in vivo, antibodies directed against bacterial surface...

Actinomyces naeslundii genospecies 1 and 2 bind to acidic proline-rich proteins (APRPs) and statherin via type 1 fimbriae and to beta-linked galactosamine (GalNAcbeta) structures via type 2 fimbriae. In addition, A. naeslundii displays two types of binding specificity for both APRPs-statherin and GalNAcbeta, while Actinomyces odontolyticus binds to unknown structures. To study the molecular bas...

AIM To compare the antibacterial effect of hydro alcoholic extract of Salvia officinalis, Pimpinella anisum, Satureja hortensis, Rhus coriaria, Carum copticum, Mentha longifolia, Achillea millefolium against Streptococcus mutans, Lactobacillus rhamnosus and Actinomyces viscosus through two in vitro methods. METHODS In this experimental study, hydro-alcoholic extracts have been prepared from t...

In the first step of our systematic study of antagonistic actinomyces, we have selected 360 active ones out of 1800 strains by the streak plate method using Sta. aureus 209-P, B. subtilis NRRL 588, B. anthracis (Ume zawa strain), E. coli (Umezawa strain), SM (Streptomycin) resistant E. c oli (Umezawa strain), Alkaligenes faecalis, Shigella sonnei, Ps. aeruginosa, K . pneumoniae, My. avium. My. ...

Dental caries is the most prevalent disease in humans globally. Efforts to control it have been invigorated by an increasing knowledge of the oral microbiome composition. This study aimed to evaluate the bacterial diversity in occlusal biofilms and its relationship with clinical surface diagnosis and dietary habits. Anamneses were recorded from thirteen 12-year-old children. Biofilm samples col...
