OBJECTIVES To investigate the effect of triclosan exposure on the antimicrobial susceptibilities of numerically important dental bacteria. METHODS A gradient plate technique was used to expose Fusobacterium nucleatum, Lactobacillus rhamnosus, Neisseria subflava, Porphyromonas gingivalis, Actinomyces naeslundii, Prevotella nigrescens, Streptococcus oralis, Streptococcus sanguis, Streptococcus ...

L. acidophilus bacteria and C. albicans fungi are the most common microorganisms isolated from oral cavity of patients suffering post-treatment root canal endodontic infections. Chlorophenol Camphor menthol (ChM) is one antimicrobials used for sterilizer but it still has many flaws. Coconut shell liquid smoke (CS-LS) a natural product that an antimicrobial activity non-toxic chemical compounds ...

Polymyxins have previously been described to have activity against Mycobacterium tuberculosis (MTB), but further research was abandoned due to systemic toxicity concerns to achieve the required MIC. Colistin methanesulfonate (CMS), a polymyxin, is well tolerated when inhaled directly into the lungs, resulting in high local concentrations. We report here for the first time, MIC and MBC data for ...

The aim of this study was to determine the antimicrobial effect of Helichrysum arenarium L. essential oil in "invitro" condition on the growth of seven microbial species including Bacillus subtilis, Escherichia coli, Staphylococcus aureus, Saccharomyces cereviciae, Candida albicans, Aspergillus flavus and Aspergillus parasiticus using micro-dilution method. The minimum inhibitory concentration ...

The gastric pathogen Helicobacter pylori has developed resistance to virtually all current antibiotics; thus, there is a pressing need to develop new anti-H. pylori therapies. The goal of this work was to evaluate the antibacterial effect of oligo-acyl-lysyl (OAK) antimicrobial peptidomimetics to determine if they might represent alternatives to conventional antibiotic treatment of H. pylori in...

We evaluated the in vivo activity of levofloxacin alone or in combination with imipenem or amikacin in a mouse model of Acinetobacter baumannii pneumonia using a susceptible strain and one with low-level resistance (MIC/MBC of levofloxacin: 0.06/0.06 and 4/4 mg/L, respectively). As demonstrated previously with other pathogens, the AUC/MIC ratio predicted the efficacy of fluoroquinolones against...

Background: Centella asiatica leaves ethanol extract (CALEE) has higher concentration compared to other structures within the plant. The contains alkaloids, saponins and flavonoids, which play an active role as antioxidant antibacterial. Current study aimed determine effect of CALEE on Proteus mirabilis, vulgaris, Yersinia enterocolitica, Gram-negative bacteria that cause diarrhea. Materials me...

The in vitro antibacterial activity of ginger (Zingiber officinale) essential oil (GEO) was tested against five Gram-negative and Gram-positive fish pathgenic bacteria isolated from farmed olive flounder (Paralichthys olivaceus) in Korea. According to the results of disk diffusion, minimum inhibitory and minimum bactericidal concentration (MIC and MBC) tests, GEO was active against most of the ...

Background: Considering the increasing resistance of bacteria to antibiotics and the presence of antibacterial agents in plantsObjectives: the aim of this study was the antimicrobial and antibiofilm activity of Tecomella undulata and Momordica charantia ethanol and aceton leaf extract on antibiotic resistance Acinetobacter baumannii.Methods: The leaves of Tecomella undulata and Momo...
