Candida is usually considered a commensal with the potential to cause opportunistic infections ranging from supercial mucosal infections to lifethreatening invasive infections. This study was aimed to determine antifungal susceptibility patterns of Candida species isolated from various clinical specimens from a tertiary care hospital. Isolation and identic Material and Methods: ation of Candida species were done by morphological examination, pseudohyphae, and chlamydospore production on cornmeal agar, germ tube test, and HiCrome Candida differential agar. The antifungal susceptibility of Candida strains was performed by the disk diffusion method as per the CLSI M44-A2 protocol. A Result: total of 96 Candida species were isolated from various clinical specimens. The isolation rate was more in the older age group and female patients(52%). Most frequently isolated from urine 41.67% followed by sputum 19.79%, Blood 16.67%, and least from vaginal swab 2.08%. Four species of Candida were isolated among them Candida albicans was most common 59.37% followed by Candida prapsilosis and Candida krusei 15.62%, and Candida tropicalis 9.37%. In antifungal susceptibility testing, Itraconazole was the most sensitive drug and Fluconazole was the least sensitive one with only 58.33% susceptibility among individual species. Concussion: Urinary tract infection was common due to Candida albicans, and Itraconazole was the most susceptible drug.

Background: Candida albicans remains the most common and are responsible for various clinical infections ranging from mucocutaneous infection to life threatening invasive diseases. But recent epidemiological data shift from C.albicans to non albicans Candida species and also increased resistance to antifungal drugs made the scenario a serious concern. Methods: A total of 156 Candida isolates from various clinical specimens received in the department of Microbiology were taken up for the study over a period of one year i.e. from March 2019 to February 2020. The Candida were grown on Sabouraud dextrose agar to be  evaluated for colony  appearance, macroscopic examination, Gram staining, germ tube, urea hydrolysis etc. The Candida isolates were speciated by using CHROMagar medium. Antifungal susceptibility testing was performed as recommended by Clinical and Laboratory Standards Institute (CLSI) M44-A document. Results: The isolation of non albicans Candida (54.5%) predominated over Candida albicans (45.5%). Non albicans Candida isolated were Candida tropcalis 40(25.6%), Candida krusei 21(13.4%), Candida glabrata 17(10.8%) and Candida dublinensis 07(4.4%) each. Candida species were all susceptible to Amphotericin B, followed by fluconazole (67.4%), miconazole (51.9%) and ketoconazole (22.5%). Conclusions: The accurate species identification of Candida is important for the treatment because not all species respond to the same treatment and also because of the increasing antifungal resistance. CHROMagar is a convenient and rapid method of identification of Candida species specially in resource limited poor settings.   Keywords: antifungal susceptibility testing; Candida albicans; CHROMagar; non albicans Candida

<p><strong>Background:</strong> Candida species are responsible for various clinical manifestations from mucocutaneous overgrowth to blood stream infections especially in immunocompromized situations. Although C. albicans is the most prevalent species, high incidence of non-albicans Candida species with antifungal resistance are emerging which is posing a serious threat to the patients care.</p><p><strong>Objective:</strong> This study aimed to isolate and identify different species of Candida from different clinical specimens. Methods: A total of 100 different clinical specimens were studied of which 35 were oral swab, 28 were high vaginal swab, 15 were urine, 14 were nail, 04 were bronchoalveolar lavage and peritoneal fluid were 04. Among 100 clinical specimens, Candida isolates were identified in 64 specimens. Isolation of Candida species was done by primary culture in SDA. Subsequent identification of species were performed by germ tube test, subculture in chromo­genic agar medium and carbohydrate assimilation test with commonly used twelve sugars.</p><p><strong>Results:</strong> Out of 64 isolated Candida species, Candida albicans were 51.56% and the non-albicans Candida species were 48.44%. The most prevalent Candida species was C. albicans 33 (51.53%) followed by C. tropicalis 17 (26.56%). C. glabrata 4 (6.25%), C. parapsilo­sis 4 (6.25%), C. krusei 3 (4.68%) and C. guilliermondii 2 (3.2%). One of the isolated Candida species was unidentified.</p><p><strong>Conclusion:</strong> Though Candida albicans was found as the most common species, but non-albicans Candida species are appearing as emerging pathogens as well. Exposure to chemotherapy appeared to be the commonest predisposing factor for Candida infection followed by indwelling urinary catheter in situ for prolong period.</p>

Abstract The aim of this work was to study the epidemiology of candidemia in our hospital in order to determine whether the T2MR system might be a useful tool for early diagnosis of candidemia in selected units. We perform a retrospective review of all candidemia episodes registered in the last 12 years in selected units of our hospital in adult and pediatric patients. Candida species and antifungal susceptibility patterns were registered. A total of 686 isolates were registered, of which 625 were infections due to the five most common species of Candida. C. albicans (45.6%) and C. parapsilosis (33.1%) were the predominant species found in our institution. In adults these species were closely followed by C. glabrata (12–21%) in all units. While in pediatric medical and intensive care units (PICU), these species were followed by other uncommon yeasts. Resistance rates to triazoles were low in C. albicans and C. parapsilosis. In C. glabrata and C. tropicalis the resistance rates to fluconazole ranged from 10.86 to 6.67%. Resistance rates for echinocandins were very low and all strains were susceptible to amphotericin B. T2Candida® might be useful to guide antifungal targeted treatment and discontinuation of antifungal empirical treatment in those units where the five most common Candida species represent more than the ninety percent of the isolates. The selection of medical and surgical units should be based on local epidemiology and antifungal susceptibility patterns. Incidence should be taken into account in order to make clinical decisions based on negative results. Lay Abstract T2Candida® might be useful selectively in clinical units according to their local epidemiology, antifungal resistance patterns, and incidence of candidemia. It optimizes the clinical value of positive results supporting decisions about targeted therapies or discontinuations based on negative results.
