Eighteen (3R) and (3R,4R)-N-phenyl-, N-phenylalkyl and N-arylsuccinimides were prepared with high enantioselectivity by biotransformation of maleimides with A. fumigatus. This environmentally friendly, clean and economical procedure was performed by the whole-cell fungal bioconversion methodology. Their corresponding eighteen racemic succinimides were prepared instead by synthetic methods. Both...

The in vitro activities of aivlosin tylosin tiamulin, erythromycin, oxytetracycline, spectinomycin, lincomycin, lincomycin-spectinomycin (1:2) and enrofloxacin were determined against twenty-eight isolates of Mycoplasma gallisepticum and 4 isolates of Mycoplasma synoviae using microbroth dilution method. The isolates showed various susceptibilities to antimicrobial agents. Aivlosin, lincomycin-...

OBJECTIVE The objective of the study was to investigate the prevalence of vancomycin-resistant Staphylococcus aureus (VRSA). MATERIALS AND METHODS Three hundred and fifty-six S. aureus isolates from the Imam Khomeini hospital in Tehran, Iran, were evaluated for methicillin and decreased vancomycin susceptibility by the microbroth dilution method. The mecA, vanAand vanB genes were targeted by ...

Cyclohex-3-enyl(5-phenyl-4H-1,2,4-triazol-3-yl)methanol (MSDRT 12) is a novel triazole-based antitubercular compound with two chiral centers. To evaluate the enantiospecific antitubercular activity, the four stereoisomers were isolated using preparative chiral chromatography and the individual stereoisomers were evaluated using the resazurin microtiter assay method (REMA) and a microbroth dilut...

Objective: this study designed to test the antibacterial potency of enrofloxacin (ENR) and essential oils from Zataria multiflora Boiss (ZEO) and Trachyspermum copticum (TEO)on Aeromonas hydrophila. Material and Methods: The antibacterial potency of test compounds was determined by several methods including the inhibition zone diameter determination, microbroth dilution method and colorimetric...

The aim of the present study was to evaluate the antimicrobial activity of Tinospora cordifolia extracts against three standard ATCC strains of Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa. The efficacy of extract was measured in terms of Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC) and zone of inhibition (mm). Antimicrobial activity of ...

To enhance the bioactivity of molecules through nanoparticles is being tested which has potential use in sustained-release drug delivery systems and to therapeutic effectiveness drugs. Our current investigation s conjugate lectin that a gold nanoparticle (GNP) surface without disturbing bioactive properties enhances antibacterial activity lectin. Au-lectin were checked for their hemagglutinatio...

Ribosomally synthesized (natural) peptides demonstrate antimicrobial potency and may represent a novel therapeutic approach for the treatment of infections. The aim of the present study was to investigate the interaction between polycationic peptides and clinically used antimicrobial agents in the treatment of clinical isolates of Gram-positive and Gram-negative aerobic bacteria in vitro, using...

Candida parapsilosis is emerging as a potential pathogen for onychomycosis. A 4-year-old male child with perimembranous ventricular septal defect (VSD) was admitted with features of cystitis and was treated with broad spectrum antibiotics. Two weeks later, he developed yellowish discoloration of nails of both hands. The sloughed out nail, on microscopy, showed numerous yeast forms that were ide...
