The occurrence of vancomycin-resistant Staphylococcus aureus (VRSA) and multidrug-resistant (MDR) strains of this organism necessitate the discovery of new classes of anti-staphylococcal drug leads. At present there are no single chemical entity plant derived antibacterials used clinically, and this biologically diverse group deserves consideration as a source of chemical diversity for two impo...

Natural products continue to serve as one of the best sources for discovery of antibacterial agents as exemplified by the recent discoveries of platensimycin and platencin. Chemical modifications as well as discovery of congeners are the main sources for gaining knowledge of structure-activity relationship of natural products. Screening for congeners in the extracts of the fermentation broths o...

The antibacterial effect of thyme, peppermint, sage, black pepper and garlic hydrosols, widely used in food products as drinks and food additives, were tested for their inhibitory effects against Bacillus subtilis and Salmonella enteritidis. Single and combined hydrosols of previous common herbs were used to evaluate in vitro the antibacterial activity against these pathogenic bacteria. The obt...

The aim of this study was to evaluate the effect of EDTA, lysozyme, or the combination of EDTA and lysozyme on the antibacterial activity of ovotransferrin against Escherichia coli O157:H7. Ovotransferrin solutions (20 mg/mL) containing 100 mM NaHCO3 (OS) with added EDTA (2.0 or 2.5 mg/mL), lysozyme (1.0, 1.5, or 2.0 mg/mL), or both were prepared. The antibacterial activities of OS, OSE (OS+EDT...

INTRODUCTION The main goal of endodontic treatment is elimination of bacteria and their by-products from infected root canals. This study compared the antibacterial effect of two different sealers, AH 26 and MTA Fillapex, on 4 microorganisms 24, 48 and 72 h and 7 days after mixing. METHODS AND MATERIALS The microorganisms used in this study consisted of Lactobacillus acidophilus (ATCC 4356), ...

E-mail: [email protected] Abstract Ubiquitousness and increasing prevalence of dental caries makes it one of the most important problems in public health. Due to high cost and lack of resources at primary levels prevention is better in dental caries. Since the origin is related t...

INTRODUCTION The purpose of this study was to compare the inhibitory effect of bovine serum albumin (BSA) and hydroxyapatite (HA) on the antibacterial activity of white-colored MTA (WMTA) against Staphylococcus (S.) aureus and Streptococcus (S.) mutans after 24 and 72 hours. MATERIALS AND METHODS All materials were prepared according to the manufacturer's directions immediately before testing...

In order to discover new antibacterial agents, series of 2-salicyloylbenzofuran derivatives were designed, synthesized and evaluated for their antibacterial activities against three Gram-(+) strains (methicillin-sensitive Staphylococcus aureus (MSSA) ATCC 29213, methicillin-resistant Staphylococcus aureus (MRSA) ATCC 43300, and Streptococcus faecalis (S. faecalis) ATCC 29212) and one Gram-(-) s...
