Vancomycin resistance exhibited by Enterococcus faecalis isolates V583, V586, and V587 is described. The vancomycin MICs ranged from 32 to 64 micrograms/ml. Although resistant to vancomycin, the isolates were susceptible to teicoplanin (MIC, less than or equal to 0.5 micrograms/ml). Such a glycopeptide susceptibility profile has not been previously described for E. faecalis. Time kill studies s...

Water-soluble gold(I) complexes [1-mesityl-3-(3-sodiumsulfonatopropyl)imidazol-2-ylidene] gold(I) Chloro (3) and [1,3-bis(2,6-diisopropyl-4-sodiumsulfonatophenyl)imidazol-2-ylidene] gold(I) Chloro (4) were prepared, in high yield, by carbene transmetallation from the appropriate NHC silver complex with chloro tetrahydrothiophene gold ([AuCl(tht)]). The antimicrobial properties of both gold(I) c...

Fifty dermatophyte strains, recently obtained from clinical material, belonging to 4 different species were examined for their susceptibility to 5 systemic or topical antimycotic agents using both an agar macrodilution and a broth microdilution test. Antimycotics compared were griseofulvin, itraconazole, sertaconazole, terbinafine and ciclopiroxolamine. A comparison of the minimum inhibitory co...

The antioxidant properties and antimicrobial activity of rosemary extracts were compared to those of vine leaf extracts. The phenolics were quantified by HPLC. Rosemary extracts were stronger in reducing power than vine leaf extracts but possessed weaker superoxide anion radical (O2 ) scavenging capability. The antimicrobial activity was confirmed by the broth microdilution test using minimal i...

One hundred ninety-five individual vancomycin-resistant Enterococcus faecium (VRE) isolates from five upstate New York hospitals were studied for antimicrobial susceptibilities to LY333328, quinupristin-dalfopristin, teicoplanin, ampicillin, and gentamicin. LY333328 was the most active antibiotic against VRE. The effect of media and methods on the antibacterial activity of LY333328, its synergy...

AIM To compare the antibacterial effect of hydro alcoholic extract of Salvia officinalis, Pimpinella anisum, Satureja hortensis, Rhus coriaria, Carum copticum, Mentha longifolia, Achillea millefolium against Streptococcus mutans, Lactobacillus rhamnosus and Actinomyces viscosus through two in vitro methods. METHODS In this experimental study, hydro-alcoholic extracts have been prepared from t...

Objective. To evaluate in vitro antifungal activity of thiabendazole against strains of dermatophytes using a reference method for filamentous fungi. Materials and Methods. Dermatophytes' susceptibility to thiabendazole (TBZ) and fluconazole (FCZ) was evaluated using macrodilution method of protocol M38-A2 of the Clinical and Laboratory Standards Institute (CLSI). Results. MIC ranges of TBZ for...

Flucloxacillin, fosfomycin, fusidic acid, teichomycin, and vancomycin were tested against 50 clinical isolates of methicillin-resistant Staphylococcus aureus by a broth macrodilution technique. Teichomycin had a narrow range of activity, similar to that of vancomycin (0.5 to 2.0 micrograms/ml). Fusidic acid had the lowest range of inhibitory activity, with 50 and 90% MICs of 0.19 and 0.35 micro...
