MICs of daptomycin, linezolid, and vancomycin against 212 isolates, including Listeria monocytogenes and Pediococcus, Leuconostoc, Rhodococcus, and Nocardia spp., were determined by the broth microdilution method; daptomycin MICs were also determined by the Etest. Except with those for Leuconostoc spp., daptomycin Etest MICs showed >90% agreement with MICs obtained by the broth microdilution me...

MICs of antibiotics against Bilophila wadsworthia isolates were measured by agar and broth microdilution with pyruvic acid and by Etest. The inoculum size influenced greatly agar dilution. Despite discrepancies in MICs depending on the measurement method used, clindamycin consistently showed potent activity. Broth microdilution and Etest appear to be candidates for laboratory susceptibility tes...

The objective was to establish and standardise a broth microdilution susceptibility testing method for porcine Bordetella (B.) bronchiseptica. B. bronchiseptica isolates from different geographical regions and farms were genotyped by macrorestriction analysis and subsequent pulsed-field gel electrophoresis. One reference and one type strain plus two field isolates of B. bronchiseptica were chos...

Sparfloxacin and levofloxacin were evaluated against 150 Haemophilus influenzae isolates and 149 Neisseria gonorrhoeae isolates in order to define susceptibility testing parameters. Sparfloxacin-susceptible H. influenzae strains were defined as those for which the MICs were < or = 0.25 microgram/ml and the zones were > or = 30 mm, and N. gonorrhoeae susceptible strains were those for which the ...

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...

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...

MIC end points for the most commonly prescribed azole antifungal drug, fluconazole, can be difficult to determine because its fungistatic nature can lead to excessive "trailing" of growth during susceptibility testing by National Committee for Clinical Laboratory Standards broth macrodilution and microdilution methods. To overcome this ambiguity, and because fluconazole acts by inhibiting ergos...

The in vitro antistaphylococcal activity of RP 59500, a new streptogramin, was comparable to those of vancomycin and teicoplanin against Staphylococcus aureus, and RP 59500 was the most active agent against coagulase-negative staphylococci. All staphylococcal strains were inhibited by 4 micrograms of RP 59500 per ml, including multiply resistant strains. Broth microdilution and agar dilution te...

In this study, the antifungal activities of limonene against Trichophyton rubrum were evaluated via broth microdilution and vapor contact assays. In both assays, limonene was shown to exert a potent antifungal effect against T. rubrum. The volatile vapor of limonene at concentrations above 1 µl/800 ml air space strongly inhibited the growth of T. rubrum. The MIC value was 0.5% v/v in the broth ...
