Background and Objective: Acne is one of the medical problems and propionibacterium acnes is the pathogenic agent that has received a considerable attention. Different parts of Juglans regia have been shown to have antibacterial activity on many bacteria. Its leaves have antioxidant property and if it shows antibacterial effect on propionibacterium acnes, it might be an alternative drug for the...
BACKGROUND Fluoroquinolones are the drugs of choice for the treatment of typhoid fever. But the recent increase in minimum inhibitory concentration (MIC) values of ciprofloxacin in Salmonella Typhi may result in delayed response and serious complications. Nalidixic acid resistance has been used as an indirect evidence of increased minimum inhibitory concentration for ciprofloxacin in Salmonella...
The Mekong Delta in Vietnam has seen a rapid development and intensification of aquaculture in the last decades, with a corresponding widespread use of antibiotics. This study provides information on current antibiotic use in freshwater aquaculture, as well as on resulting antibiotic concentrations in the aquatic environment of the Mekong Delta. Two major production steps, fish hatcheries and m...
Increasing antibacterial resistance and pathogenicity in the environment is of growing concern due to its potential human risk. In the present study, 236 Escherichia coli isolates were collected from Wenyu River in China on drugless (48 isolates) and quinolone-containing plates (189 isolates). Their minimum inhibitory concentrations (MICs) were determined ranging from 0.125 μg mL(-1) to 128 μg ...
Metal susceptibility assays and spot plating were used to investigate the antimicrobial activity of enantiopure [Ru(phen)2 dppz]2+ (phen =1,10-phenanthroline and dppz = dipyrido[3,2-a:2´,3´-c]phenazine) and [μ-bidppz(phen)4 Ru2 ]4+ (bidppz =11,11´-bis(dipyrido[3,2-a:2´,3´-c]phenazinyl)), on Gram-negative Escherichia coli and Gram-positive Bacillus subtilis as bacterial models. The minimum inhib...
Background: Florfenicol (Ff) is a synthetic antibiotic with a broad antibacterial spectrum and high therapeutic effectiveness that was specifically developed for veterinary use as well as, doxcycline is an antibiotic synthetically derived from oxytetracycline. Methods: In the present study, the in-vitro efficacy of Ff and doxcycline against Salmonella entertidis and Escherichia coli (Serotype O...
A series of 21 anilinobenzimidazoles with a 2,4-difluorophenyl group were synthesized and their minimum inhibitory concentrations (MIC) determined by the tube dilution method. Most of the compounds exhibited excellent MIC values against Staphylococcus aureus and methicillin-resistant S. aureus (MRSA). Among them, compound 27 having dibromo substitution at the 4- and 6-position of the benzimidaz...
AIMS To demonstrate that the nonlinear concentration-dependent inhibition of Pseudomonas aeruginosa to EDTA can be used to successfully model and predict the potentiation of antimicrobials by EDTA. METHODS AND RESULTS A model used successfully to describe the concentration-dependent inhibition of bacterial growth caused by many antimicrobials was unable to describe the inhibition of P. aerugi...
BACKGROUND Recent reports have described decreased effectiveness with vancomycin treatment for methicillin-resistant Staphylococcus aureus bacteremia (MRSAB) when the vancomycin minimum inhibitory concentration (MIC) is >1 µg/mL. METHODS This matched, retrospective cohort study compared the clinical effectiveness of daptomycin with that of vancomycin for the treatment of MRSAB with vancomycin...
Acinetobacter baumannii is an important pathogen, capable of survival for very long periods on various surfaces in the hospital environment. Tigecycline is a commonly used antimicrobial agent especially for the treatment of resistant infections. The aim of this study was to investigate the activity of tigecycline on both planktonic and sessile biofilm cells of A. baumannii strains isolated from...
