background and objectives: bacterial resistance to antibiotics has motivated the researchers to evaluate the novel anti-bac- terial compounds such as some thiazole and imidazole derivatives. thereby, in this work, we investigated the anti-bacterial effects of one new thiazole and two new imidazole derivatives on bacillus cereus , listeria monocytogenes , escherichia coli, salmonella typhimurium...

nowadays, uncontrolled and frequent use of antibiotics may cause emergence of microbial resistanceamong pathogenic agents. therefore, the use of new synthetic and natural antimicrobial compounds isinevitable. one source of natural compounds in this respect comes from plants. the purpose of this study was to examine the antibacterial effects of peel extracts from sour and sweet pomegranate. meth...

abstract       background and objectives: antibiotic resistance in bacteria has actuated researchers toward evaluating many new antibacterial compounds of which are the thiazoles. in this research the inhibitory effects of novel thiazole derivatives were unraveled on staphylococcus aureus, streptococcus agalactiae, pseudomonas aeruginosa and klebsiella pneumoniae and oxothiazole liver toxicity ...

objectives the aim of this study was to evaluate the stability of antibacterial properties of nanosilver solution during a period of 9 months against streptococcus mutans, staphylococcus aureus and pseudomonas aeruginosa. materials and methods in this in vitro study, the antibacterial effect of serial concentrations of nanosilver solution and amoxicillin antibiotic as control group on the stand...

the aim of this paper was to investigate the antibacterial potential of kelussia odoratissima mozff extract against gram-negative and gram-positive bacteria. karafs-ekoohi with the scientific name of kelussia odoratissima is an iranian endemic edible plant in the middle region of iran with enormous use as food, spice and medicinal herb . the antibacterial effect of the extracts was investigated...

Selective antihistamine receptor type 2 blockers are widely used for treatment of peptic ulcer, these drugs are famotidine,cimetidine,nizatidine and ranitidine and because many nonantibiot ics agents have antibacterial activity so this study aimed to evaluate the antibacterial effects of selective H2 blockers. Tewnty two of bacterial strains were slected 5 Staphylococcus aureus,5 Escherichia co...

The safe and effective elimination of food borne pathogens represents an important unmet need. Multiple lines of converging evidence point to the use of olive juice and olive oil polyphenols, particularly HIDROXTM and hydroxytyrosol, to protect foods against pathogens. HIDROXTM and hydroxytyrosol are natural products that exert significant antibacterial effects against food borne bacteria. Mult...

We determined the prevalence of plasmid-mediated quinolone resistance mechanisms among non-Typhi Salmonella spp. isolated from humans, food animals, and retail meat in the United States in 2007. Six isolates collected from humans harbored aac(6')Ib-cr or a qnr gene. Most prevalent was qnrS1. No animal or retail meat isolates harbored a plasmid-mediated mechanism.

The pharmacokinetics of the quinolone enoxacin were studied after a 600-mg oral dose was given to each of six male volunteers. The levels of the compound were measured in serum, blister fluid, and urine. Absorption was variable, with peak levels (mean, 3.7 micrograms/ml) being attained between 0.75 and 3.0 h (mean, 1.9 h). The serum elimination half-life was 6.2 h, and 71.6% of the drug was rec...

AIM To evaluate the antibacterial, physicochemical and mechanical properties of two endodontic sealers incorporating quaternary ammonium polyethylenimine (QPEI) nanoparticles at concentrations of 1% and 2% (w/w). METHODOLOGY The sealers tested were AH Plus and Pulp Canal Sealer EWT in the commercial unmodified form or containing 1% or 2% QPEI. Antibacterial activity was evaluated using a dire...
