Antibiotic resistance in bacteria isolated from subgingival plaque in a norwegian population with refractory marginal periodontitis.

The Relationship between Cell Surface Hydrophobicity and Antibiotic Resistance of Streptococcal Strains Isolated from Dental Plaque and Caries

Objective Bacterial adhesion is governed by specific and nonspecific interactions such as hydrophobicity. Hydrophobic interactions play a role in the adherence of microorganisms to a wide variety of surfaces and facilitate biofilm formation due to bacterial adhesion. In this article the relation between cell surface hydrophobicity and antibiotic resistance was studied. Materials and Methods ...

Antibody Titer Against Porphyromonas Gingivalis in Rats with Experimentally Induced Periodontitis

Background and Aim: This study aimed to assess the antibody titer against Porphyromonas gingivalis (P. gingivalis) in rats with experimentally induced periodontitis. Materials and Methods: Thirty-three Surrey rats were randomly divided into three groups (n=11). Group 1 was vaccinated with formalin-killed whole cell (FKWC) P. gingivalis with incomplete Freund's adjuvant as vaccine carrier and o...

Molecular Detection of Antibiotic Resistance Determinants in Lactobacillus Bacteria Isolated from Human Dental Plaques

Introduction: Dental caries is a significant public health problem which destroys the calcified tissues of the teeth. The frequency of lactobacilli in dental caries is usually high. The objective of this study was to evaluate the incidence of these bacteria in dental caries and to identify the antibiotic resistance patterns of them. Methods: Specimens from dental plaque were collected from 30 p...

Prevalence of Periodontopathic Bacteria in the Subgingival Plaque of a South Indian Population with Periodontitis

Subgingival microbial profiles in refractory periodontal disease.

BACKGROUND/AIM The purpose of the present investigation was to examine subgingival microbial profiles associated with refractory periodontitis and to seek such profiles in periodontally healthy, periodontally well-maintained elder and untreated periodontitis subjects. METHODS 36 subjects were defined as refractory on the basis of further attachment loss after scaling and root planing, surgery...
