A total of 97 anaerobic bacteria were tested for susceptibility to ampicillin, ampicillin-sulbactam, and amoxicillin-clavulanic acid by broth microdilution and disk elution methods, the results of which were compared with those of the reference agar dilution method. With the broth microdilution method, approximately 95% of MICs were within 1 dilution of those of the reference agar method, with ...

Endpoint determinations of endotoxin by the Limulus amoebocyte lysate assay have been facilitated by use of a microdilution procedure.

Broth microdilution susceptibility tests of Candida species have now been standardized by the National Committee for Clinical Laboratory Standards (NCCLS). An eight-laboratory collaborative study was carried out in order to document reproducibility of tests of Candida parapsilosis ATCC 22019 and Candida krusei ATCC 6258 by the NCCLS method. Replicate broth microdilution tests were used to defin...

results the sequence analysis of the isolate confirmed as c. glabrata and deposited on ncbi genbank under the accession number no. kt763084-kt763123. the geometric mean mics against all the tested strains were as follows, in increasing order: casp (0.17 g/ml), vcz (0.67 g/ml), amb (1.1 g/ml), itz (1.82 g/ml), ktz (1.85 g/ml), and fcz (6.7 g/ml). the resistance rates of the isolates to casp, fcz...

objective: sea cucumber is a traditional food and medical item and has been reported to exhibit antioxidant, antifungal, anti tumoral and antibacterial bioactivity. the objective of this study is to describe the antibacterial activity of 4 extracts of holoturia. sp (sea cucumber), collected from hengam island of persian gulf. materials and methods: methanol, hexane, aqueous and chloroform extr...

manganese oxide nanoparticles (mn3o4-nps) were prepared using precipitation method. the prepared nanoparticles were characterized by a number of techniques, including x-ray diffraction (xrd) analysis, scanning electron microscopy (sem), transmission electron microscopy (tem) and fourier transforms infra red (ft-ir) spectroscopy. the xrd pattern showed that the structure of mn3o4-nps was tetrago...

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...

A new rapid microdilution method, employing the dye resazurin as an indicator of mycobacterial growth, was developed to evaluate drug susceptibility of Mycobacterium tuberculosis reference strain H37Rv and of 13 M. tuberculosis susceptible or multidrug-resistant clinical strains. Different growth conditions were evaluated. The MICs of isoniazid, rifampicin, streptomycin and ethambutol were dete...
