Antibacterial effects of conventional glass ionomer cement.

Objectives: The antibacterial activity of conventional glass ionomer cement against three different microorganism strains alone and following incorporation of 1, 2 and 3% Benzalkonium Chloride and Cetylpyridinium Chloride was evaluated.

Methods: Agar diffusion method was used to determine the inhibitory effect of the conventional glass ionomer cement ChemFlex on Streptococcus mutans, Lactobacillus casei and Actinomyces viscosus. Bacterial strains were inoculated into BHIB, and incubated in an anaerobic atmosphere (37 °C).

Gastrointestinal Colonization with Vancomycin-Resistant Enterococci In Hospitalized and Outpatients.

Background: The incidence of infection and intestinal colonization with vancomycin resistant enterococci (VRE) is increasing in many countries in the last decade. Concerning the difficult antimicrobial treatment of infections caused by VRE, decreasing the incidence and prevalence of these infections is an important factor in VRE-induced morbidity and mortality control.

Aim: To determine the prevalence of gastrointestinal colonization with vancomycin resistant enterococci in hospitalized and outpatients, and to determine the genetic base of the vancomycin resistance in VRE isolates.

Chemical composition and antimicrobial activity of the essential oils of Pinus peuce (Pinaceae) growing wild in R. Macedonia.

The chemical composition and antimicrobial activity of the essential oils isolated from twigs with needles (T+N) and from twigs without needles (T-N) from wild Pinus peuce Griseb. (Pinaceae), from three different locations in R. Macedonia, were investigated.

Genotypes of ESBL producing Escherichia coli and Klebsiella pneumoniae in relation to resistance to antimicrobial drugs.

Unlabelled: The aim of the study was to evaluate the association of drug resistance with β-lactamase gene types in ESBL positive E. coli and Klebsiella pneumoniae-Kp.

Material And Methods: A total of 251 ESBL-positive E.

Incorporation of antimicrobial agents can be used to enhance the antibacterial effect of endodontic sealers.

Aim: The antibacterial activity of five endodontic sealers against three different microorganism strains alone and following incorporation of 2% benzalkonium chloride (BC) and 2% cetylpyridinium chloride (CPC) was evaluated.

Methodology: The agar diffusion method was used to determine the inhibitory effect of the following endodontic sealers: RoekoSeal, Endomethasone N, N2, Apexit Plus and AH plus, on Streptococcus mutans - ATCC 25175, Lactobacillus casei - ATCC 4646 and Actinomyces viscosus - ATCC 19246. Bacterial strains were inoculated into BHIB, and incubated in an anaerobic atmosphere (37 °C).
