Three pharmacokinetic/pharmacodynamic parameters--(i) the peak concentration to the minimum inhibitory concentration ratio (C(max)/MIC); (ii) the area under the concentration-time curve to MIC ratio (AUC(24h)/MIC); and (iii) the time the concentration exceeds the MIC (T>MIC)--are important predictors of the clinical efficacy of antibiotics. For antibiotics with pronounced concentration-dependen...

OBJECTIVES The aim of this study was to determine the antimicrobial resistance patterns of 125 Campylobacter jejuni and 27 Campylobacter coli isolates from 39 Queensland broiler farms. METHODS Two methods, a disc diffusion assay and an agar-based MIC assay, were used. The disc diffusion was performed and interpreted as previously described (Huysmans MB, Turnidge JD. Disc susceptibility testin...

Eighty Candida albicans strains, isolated from throat of patients at the Universitary Clinic of the Faculty of Superior Studies Iztacala of the National Autonomous University of Mexico, were analyzed. They were identified by microscopic and colony morphologies, germ tube test, and by auxanogram and zimogram. Minimal inhibitory concentrations (MIC) of 5-fluorocytosine, miconazole and amphoterici...

To study the hypothesis of the mutant selection window (MSW) in a pharmacodynamic context, the susceptibility of a clinical isolate of methicillin-resistant Staphylococcus aureus exposed to moxifloxacin (MOX), gatifloxacin (GAT), levofloxacin (LEV), and ciprofloxacin (CIP) was tested daily by using an in vitro dynamic model that simulates human pharmacokinetics. A series of monoexponential phar...

Abstract Riboflavin, a soluble redox mediator for electron transfer, is involved in various processes biogeochemical systems. This work gives some insights into the MIC mechanism of pure nickel (Ni) caused by Desulfovibrio vulgaris . Compared with copper (Cu) metabolite (M)-MIC, Ni D. exhibits distinctly different corrosion behavior. 20 ppm (w/w) riboflavin dramatically enhances rate (59% incre...

The first aim of this study is to evaluate the in vitro antimicrobial activity of the essential oil and two extracts of Saharan myrtle: Myrtus nivellei Batt & Trab. For this purpose, paper disc-diffusion method and micro-dilution test were used. As far as the antimicrobial activity is concerned the essential oil exhibited higher ones against S. epidermidis (MIC=0.28mg/ml), S. typhi (MIC=0.56mg/...

Two homosexual men were colonized in the urethra with Haemophilus parainfluenzae nonsusceptible to ampicillin (MIC, 8 μg/ml), amoxicillin-clavulanate (MIC, 4 μg/ml), cefotaxime (MIC, 1.5 μg/ml), cefepime (MIC, 3 μg/ml), meropenem (MIC, 0.5 μg/ml), cefuroxime, azithromycin, ciprofloxacin, tetracycline, and chloramphenicol (all MICs, ≥ 32 μg/ml). Repetitive extragenic palindromic PCR (rep-PCR) sh...

The placenta and fetal membranes are the site of expression of macrophage inhibitory cytokine (MIC-1), a member of the transforming growth factor (TGF)-beta superfamily. We hypothesized that MIC-1 may act as an immune regulator in pregnancy complications associated with intrauterine inflammation. Decidual cells, chorionic trophoblasts and amnion epithelial cells were identified by immunohistoch...

Macrophage inhibitory cytokine-1 (MIC-1/GDF15), a divergent member of the TGF-β superfamily, is over-expressed by many common cancers including those of the prostate (PCa) and its expression is linked to cancer outcome. We have evaluated the effect of MIC-1/GDF15 overexpression on PCa development and spread in the TRAMP transgenic model of spontaneous prostate cancer. TRAMP mice were crossed wi...
