OBJECTIVE This study is to define the statistical significance for detection of ESBL producers by the double disk synergy test and molecular test (Check-MDR CT102), microdilution test (VITEK 2 with AES) and double disk synergy test (DDST), as well as the microdilution test and molecular test. MATERIALS AND METHODS Phenotypic testing of 55 isolates Enterobacteriaceae (Escherichia coli (14/55),...

The purpose of the study was to evaluate the interlaboratory agreement of broth dilution susceptibility methods for five species of conidium-forming (size range, 2 to 7 microns) filamentous fungi. The methods used included both macro- and microdilution methods that were adaptations of the proposed reference method of the National Committee for Clinical Laboratory Standards for yeasts (m27-P). T...

A comparison of the E test, the broth microdilution test, and the reference broth macrodilution susceptibility test of the National Committee for Clinical Laboratory Standards for fluconazole susceptibility testing was performed with 238 clinical isolates of Candida species and Torulopsis (Candida) glabrata. An 80% inhibition endpoint MIC was determined by the reference broth macrodilution meth...

The antifungal activities of itraconazole, ketoconazole, fluconazole, terbinafine and griseofulvin were tested by broth microdilution methods against 71 isolates of dermatophytes isolated from Nigerian children. Most drugs were very active against all the dermatophytes and the MIC 90 ranged from 0.03 to 8.0 microg/mL. This appears to be the first documented data on the antifungal susceptibility...

Background. IAI and SW infections present major challenges for hospitalized patients. Monitoring the resistance profiles expressed by the causative organisms is important. Therefore, data from the Tigecycline European Surveillance Trial (TEST) program were analyzed for the resistance patterns observed throughout Europe. Methods. Isolates were collected and tested locally by broth microdilution ...

Thein vitroantibacterial activities of ceftazidime-avibactam and comparator agents were evaluated using reference broth microdilution methods against 1,743Pseudomonas aeruginosaisolates collected in 2014 from 69 U.S. medical centers, representing each of the nine census regions. Ceftazidime-avibactam demonstrated potent activity againstP. aeruginosa, including many isolates not susceptible to c...

Methodology for testing natural compounds for determination of antifungal activity had been developed with adaptations. The most used are bioautography and agar diffusion with a complex and no defined media. In this study, different methods for determination of antifungal activity of natural products are discussed and the use of M27-A2 microdilution test from CLSI (Clinical and Laboratory Stand...

Twelve strains of Haemophilus influenzae were tested for susceptibility to gentamicin, ampicillin, chloramphenicol and cephalothin using two methods, agar dilution and microdilution (broth). Although inocula and incubation conditions were standardized, significant differences in the minimal inhibitory concentration (MIC) were seen as a result of growth media. Method dependent differences were a...
