BACKGROUND AND PURPOSE Little is known about the possible synergism of baicalein, a bioactive flavone of Scutellariae radix (a Chinese herb), when used in conjunction with other antimicrobial agents against vancomycin-resistant Enterococcus (VRE). This in vitro study examined the possible synergism of the combination of baicalein and gentamicin against VRE. METHODS Minimal inhibitory concentr...

  Background: Consumption of mycotoxic foods is associated with several cases of human poisoning, or mycotoxicosis, sometimes resulting in death.   Objective: Phytopreventive inhibition of Aspergillus parasiticus growth and its aflatoxin production by the essential oils extracted from Thymus kotschyanus Boiss & Hohen and Zataria multiflora Boiss. is reported in this study.   Methods: Minimal in...

serious concerns have been expressed about potential health risks of nano silver containing consumer products (agnps) therefore regulatory health risk assessment on such nanoparticles has become mandatory for the safe use of agnpsinbiomedicalproducts with special concerns to the mutagenic potentials. in this study, we examined the inhibitory and mutagenicity effects of agnps in three different ...

zhumeria majdae is a rare an endemic medicinal plantspecies grown wild in iran. the hydro distilled essential aerial part oil of z. majdae analysed by gc–ms. thirty-one compounds representing 95.36% of the aerial part oil, respectively, were identified, of which linalool (48.14%), camphor (20.71%), limonene (4.83%), trans-linalool oxide (2.69%), 3-octanone (2.34%), terpinene-4-ol (2.30%), camph...

there is a growing concern about the application of molecular methods in epidemiological studies of infectious diseases. the objective of this study was to determine the genetic stability of methicillin resistance genes in staphylococcus aureus for the evaluation of resistance strain distribution. one hundred and fifteen s. aureus isolates from patients with staphylococcal infection were collec...

background and aim: in recent years, due to the indiscriminate and irrational use of synthetic drugs, the resistance of pathogenic microorganisms has increased; therefore, new compounds are vitally needed. the purpose of this study was to investigate the effect of ethanolic and aqueous extracts of berberis vulgaris on escherichia coli, klebsiella pneumoniae, proteus mirabilis, citrobacter frund...

Biofilm formations play an important role in Staphylococcus aureus pathogenesis and contribute to antibiotic treatment failures in biofilm-associated infections. The aim of this study was to evaluate the pharmacokinetic/pharmacodynamic (PK/PD) profiles of cefquinome against an experimental catheter-related biofilm model due to S. aureus, including three clinical isolates and one non-clinical is...

The antimicrobial activity of tetracycline hydrochloride (OTC) and cinnamon (Cinnamomum zeylanicum Nees) essential oil (CEO) was evaluated against six different isolates of Paenibacillus larvae (White), the causal agent of American Foulbrood (AFB) disease in honey bee colonies. The bacteria isolates were collected from different localities of Argentine. Minimal inhibitory concentration (MIC) in...
