galbanic acid, a sesquiterpene coumarin from ferula szowitsiana , and conferol, another sesquiterpene coumarin from f. badrakema , were evaluated for their effects on the reversal of multi-drug resistance in clinical isolates of staphylococcus aureus and escherichia coli , respectively. neither galbanic acid (up to 1000 μg/ml) nor conferol (up to 400 μg/ml) by itself shows any antibacterial act...

conclusions shiitake essential oil is an effective anti-bacterial and anti-biofilm agent on important oral pathogens and has a possible therapeutic potential as an oral anti-biofilm agent. results no inhibitory effect was observed on f. nucleatum biofilms (p > 0.05). significant disruptive properties on a. actinomycetemcomitans at values lower than the mic (3.90 µg/ml) was detected (p < 0.05). ...

many species belonging to the scrophularia genus have been used since ancient times as folk remedies for many medical conditions such as scrofulas, scabies, tumors, eczema, psoriasis, inflammations. the aim of this study was to characterize the matrix metalloproteinases (mmps) inhibitor compounds of the scrophularia striata extract by bio-guide fractionation. the aerial parts of s. striata were...

The problems of multidrug-resistant (MDR) tuberculosis (TB), extensively drug-resistant (XDR) TB, and even ‘‘totally drug-resistant’’ TB (a term that is still debated), have exposed two important clinical issues [1, 2]. The first issue involves figuring out a way to prevent these difficult-to-treat diseases. The second issue is treating patients with drug-resistant TB [3]. In the meantime even ...

In monitoring gentamicin concentrations in the blood of patients with renal insufficiency, the assayed antibiotic concentration was found to be lower when the sample was drawn as heparinized plasma rather than as serum. This lowering of gentamicin concentrations by heparin was studied further by adding increasing doses of heparin and various amounts of gentamicin to human serum. With a range of...

BACKGROUND Few studies report the minimum inhibitory concentrations for antimicrobials against equine Corynebacterium pseudotuberculosis isolates. HYPOTHESIS/OBJECTIVES To evaluate trends in the in vitro activities of 20 antimicrobials against equine Corynebacterium pseudotuberculosis isolates from 1996 to 2012 and to determine if a relationship exists between the minimum inhibitory concentra...

We investigated the in vitro development of fluoroquinolone resistance in Chlamydia trachomatis and Chlamydia (Chlamydophila) pneumoniae grown in McCoy cell monolayers in supplemented Eagle's minimum essential medium. With C. trachomatis, initial passages at sub-inhibitory fluoroquinolone concentrations did not affect fluoroquinolone susceptibility. However, after an initial lag of 10-24 passag...
