Efficacy of Chromogenic Candida Agar for isolation and presumptive identification of pathogenic yeast species

Candida albicans remains the most frequently isolated yeast species; but others, inherently or potentially resistant to amphotericin B and azole compounds (C krusei, C parapsilosis, C lusitaniae, C tropicalis, and C glabrata), are also being reported.

The itraconazole discrepancy between Etests and broth spectrophotometry is high, and further work is needed to obtain a better correlation. C glabrata was the most commonly found species among denture wearers and non-denture wearers both by conventional and CHROMagar methods. 5%), and Candida glabrata was the second most common yeast isolated (174 positive samples; 10. Protect media from light during storage and incubation as the product is light sensitive. Barbeau J, Seguin J, Jean PG, Louis DK, Sylvie LA, Benoit L, et al. HardyCHROM™ Candida contains glucose and selected peptones as a nutrient supply.

Oral thrush treatment, symptoms, contagious period & remedies, reducing sugar consumption and avoiding smoking and alcohol are measures that can be taken to maintain a strong immune system. This difference may be offset by further identification costs for BiGGY agar.

If there is to be a delay in processing, the specimen should be inoculated onto an appropriate transport media and refrigerated until inoculation. The results of this study are in agreement with those described by many authors whose sensitivity and specificity rates ranged between 66. In conclusion, the newly formulated Becton Dickinson CHROMagar Candida medium is as equally suited as a differential medium for the presumptive identification of yeast species and for the detection of multiple yeast species in clinical specimens as the original CHROMagar Candida medium. The appearance and color of C. As compared to the gold standard method (culture on SDA medium), the direct microscopy methods showed 84 and 95% sensitivity for the 10% KOH and the Giemsa stain, respectively, while the specificity for both was 100% (Table 3). This is not an indication of a security issue such as a virus or attack. 5 to ≥ 32 for amphotericin B, fluconazol, and itraconazole, respectively.
