The in vitro susceptibilities of 59 avian Aspergillus fumigatus strains to amphotericin B, itraconazole, and voriconazole were determined using the standard microdilution broth method (CLSI M38-A2). Four isolates showed acquired resistance to itraconazole and voriconazole, harboring implications for the treatment of aspergillosis in both birds and humans.
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...
Increasing antibiotic resistance in gram-negative bacteria has recently renewed interest in colistin as a therapeutic option. The increasing use of colistin necessitates the availability of rapid and reliable methods for colistin susceptibility testing. We compared seven methods of colistin susceptibility testing (disk diffusion, agar dilution on Mueller-Hinton [MH] and Isosensitest agar, Etest...
The present study was conducted to evaluate the performance of cefoxitin disc diffusion method and oxacillin broth microdilution method for detection of methicillin resistant S. aureus (MRSA), taking presence of mecA gene as reference. In addition, inducible clindamycin resistance and beta-lactamase production were studied and minimum inhibitory concentration (MIC) of vancomycin for S. aureus i...
The purpose of this study was to evaluate the National Committee for Clinical Laboratory Standards agar dilution, tube dilution, and broth microdilution susceptibility tests for the measurement of teicoplanin MICs. The three standardized tests gave equivalent (within a twofold dilution) results with 98.8 to 99.0% of the 508 gram-positive clinical isolates tested, indicating that either method m...
We have determined the antifungal susceptibilities of 34 clinical isolates of the dimorphic fungus Sporothrix schenckii to 11 drugs using a microdilution method. In general, the type of growth phase (mycelial or yeast) and the temperature of incubation (30 or 35 degrees C) exerted a significant influence on the MICs.
