the increasing incidence of candidiasis and antifungal resistance as well as the introducing of new antifungal has recently encouraged performing of fungal susceptibility testing. the aim of this study was to evaluate the susceptibility profile of candida species isolated from patients admitted to yazd central laboratory to fluconazole. we used the broth microdilution method to evaluate the sus...

The susceptibility of 513 clinical isolates to doripenem was determined by broth microdilution, agar dilution, and Etest. Overall agreements for Etest and agar dilution MIC values compared to reference broth microdilution at +/-1 log(2) dilution were 88% and 94%, respectively. Etest MIC values demonstrated 98% agreement within +/-2 log(2) dilutions compared to the reference broth microdilution ...

a series of hydroxysemicarbazone derivatives of substituted diaryl ketones and acetophenones were synthesized and their structures were confirmed by analytical and spectroscopic methods including elemental analysis, infrared and nuclear magnetic resonance spectroscopy. the derivatives were prepared by a condensation reaction between n-hydroxysemicarbazide and substituted diaryl ketones or aceto...

presently appearance of resistance to antifungal agents among aspergillus species is dramatically increasing. the objective of this study was to look at the in vitro activities of antifungal drugs against iranian clinical (from nail, bronchoalveolar lavage, paranasal sinus) isolated a. flavus strains. the susceptibility of 45 aflatoxigenic and non-aflatoxigenic aspergillus flavus strains were e...

A commercially prepared frozen broth microdilution panel (Trek Diagnostic Systems, Westlake, Ohio) was compared with a reference microdilution panel for antifungal susceptibility testing of two quality control (QC) strains and 99 clinical isolates of Candida spp. The antifungal agents tested included amphotericin B, flucytosine, fluconazole, itraconazole, posaconazole, ravuconazole, and voricon...

A comparative evaluation of methods for broth macro- and microdilution susceptibility testing of fluconazole was conducted with 119 clinical isolates of Candida albicans. Macro- and microdilution testing were performed according to National Committee for Clinical Laboratory Standards recommendations. For reference macrodilution testing, an 80% inhibition endpoint (MIC 80%) was determined after ...

OBJECTIVES To determine the antibiotic susceptibility patterns of 60 strains of Laribacter hongkongensis isolated from humans and fish to eight antibiotics and compare the results obtained from broth microdilution, Etest and disc diffusion susceptibility testing. PATIENTS AND METHODS The susceptibilities of 60 isolates of L. hongkongensis from humans with gastroenteritis and fish to eight ant...

Micro-Media Systems (MMS) has developed a procedure by which microdilution trays can be filled with dilutions of antimicrobial agents, frozen, and distributed to clinical laboratories. The trays are prepared in various distribution centers throughout the United States to supply clinical laboratories in the vicinity of each center. For use, trays are removed from the freezer, allowed to thaw, an...

This study evaluated the susceptibility of pneumococci to cefditoren by agar dilution and microdilution methods (both in air) and by E-test (AB Biodisk, Solna, Sweden) and disk diffusion methods (both in CO(2)). By the three MIC tests, the MICs at which 50 and 90% of isolates were inhibited (MIC(50)s and MIC(90)s) were, respectively, as follows (in micrograms per milliliter): for the 65 penicil...

Eighty-one men with exudative urethritis were evaluated on initial visit for gonococcal urethritis by using the standard tube and newly developed microdilution Limulus amoebocyte lysate techniques. Serial dilutions of clinical specimens ranging from 1:100 to 1:102,400 were each tested, and results correlated with Gram stain and culture. Overall accuracy for predicting culture results was 98% fo...
