The appearance of colonies on the chromogenic medium CHROMagar Candida combined with observation of morphology on corn meal-Tween 80 agar was used for the identification of 353 clinical yeast isolates. The results were compared with those obtained with API yeast identification kits. The accuracy of identification and the turnaround time were equivalent for each method, and our cultural method w...

Plant growth promoting rhizobacteria (PGPR) are known to influence plant growth by various director indirect mechanisms. Thirty–two strains were isolated from 15 soils sampled in central Iran, byusing and comparing three different methods. The screening of soil samples by means of soil paste–plate method combined with isolation on mannitol agar proved to be the best strategy in terms ofreliabil...

Rapid bacterial identification (ID) and antimicrobial susceptibility tests (AST) can have a significant impact on the management of infections, especially those caused by antibiotic-resistant bacteria (1, 2, 5). However, these rapid automated methods do not overcome the need for the preparation of a suspension of the organism at a fixed density (0.5 to 0.6 McFarland standard [MF]; 1.5 10 CFU/ml...

Analysis of the cost of time and material required for the diagnosis of Enterobacteriacea isolates indicated that a conventional 17-tube (20-test) setup costs $7.98 per isolated identified. Using the API 20E, a similar identification cost $3.02. A conventional 7-tube (10-test) setup cost $3.60, whereas the comparable cost by 30% while increasing the number of isolate identified correctly by 3%....

Over a period of 26 months, we have evaluated in a prospective fashion the use of 16S rRNA gene sequencing as a means of identifying clinically relevant isolates of nonfermenting gram-negative bacilli (non-Pseudomonas aeruginosa) in the microbiology laboratory. The study was designed to compare phenotypic with molecular identification. Results of molecular analyses were compared with two commer...

Rapid identification of Candida species has become more important because of an increase in infections caused by species other than Candida albicans, including species innately resistant to azole antifungal drugs. We previously developed a PCR assay with an enzyme immunoassay (EIA) format to detect amplicons from the five most common Candida species by using universal fungal primers and species...
