Background: Indiscriminate use of antifungal agents has led to rise in infections caused by Candida species in recent years. Studies on characterization of Candida species followed by antifungal susceptibility testing can be benecial in managing this problem. Objectives: To phenotypically characterize Candida species isolated from various clinical samples and to determine its susceptibility to various antifungal agents. Methods: A total of 119 Candida spp. isolated from various clinical samples were subjected for species identication and antifungal susceptibility testing using an automated Vitek-2 compact system. Results: There was predominance of Non albicans (NAC) species (82.35%) isolated from our Hospital. Candida species were isolated predominantly from blood (68.06%) sample followed by urine (26.05%). C. tropicalis was the predominant NAC species isolated (27.73%) followed by C.krusei, C.guilliermondii (12.61% each), C.parapsilosis (10.08%) and C. glabrata (7.56%). Overall the NAC isolates were resistant to uconazole, voriconazole, caspofungin, micafungin, amphotericin-B, and ucytosine as compared to C. albicans. Conclusion: Predominance of NAC species and emergence of antifungal drug resistance among NAC species is a matter of concern. Thus highlighting that susceptibility should be performed in all cases to achieve good therapeutic results. Strict infection control strategies and a restrictive antifungal policy should be implemented for better clinical outcome.

The main objective of this study was to isolates and Non- albicans and their antifungal susceptibility testing.Thestudy was carried out in the Department of Microbiology, in Tmu Hospital Moradabad. Total numbers of 806 clinical samples were processed in which 206 isolates were taken for . Isolation and antifungal susceptibility testing done by Vitek-2 system.Out of 206 samples 77(37%) were and 129(63%) were Non-albicans (NAC). Maximum isolated species were 77(37%), followed by 70(34%), 24(12%), C. glabrata 19(9%), 12(6%), C. krusei 3(1%), C.african 1(1%).Infection caused by NAC species have increased. was the most common isolated species. ,and were shown high susceptibility to fluconazole and voriconazole. Amphotericin B, Caspofungin, Micafungin and Flucytosine shows high susceptibility towards other candida species.

Introduction Otomycosis is a common problem in otolaryngology practice. However, we usually encounter some difficulties in its treatment because many patients show resistance to antifungal agents, and present high recurrence rate. Objectives To determine the fungal pathogens that cause otomycosis as well as their susceptibility to the commonly used antifungal agents. Additionally, to discover the main reasons for antifungal resistance. Methods We conducted an experimental descriptive study on 122 patients clinically diagnosed with otomycosis from April 2016 to April 2017. Aural discharge specimens were collected for direct microscopic examination and fungal culture. In vitro antifungal susceptibility testing was performed against the commonly used antifungal drugs. We tested the isolated fungi for their enzymatic activity. Results Positive fungal infection was found in 102 samples. The most common fungal pathogens were Aspergillus and Candida species, with Aspergillus niger being the predominant isolate (51%). The antifungal susceptibility testing showed that mold isolates had the highest sensitivity to voriconazole (93.48%), while the highest resistance was to fluconazole (100%). For yeast, the highest sensitivity was to nystatin (88.24%), followed by amphotericin B (82.35%), and the highest resistance was to terbinafine (100%), followed by Itraconazole (94.12%). Filamentous fungi expressed a high enzymatic ability, making them more virulent. Conclusion The Aspergillus and Candida species are the most common fungal isolates in otomycosis. Voriconazole and Nystatin are the medications of choice for the treatment of otomycosis in our community. The high virulence of fungal pathogens is owed to their high enzymatic activity. Empirical use of antifungals should be discouraged.

Background: Candida species are responsible for various clinical infections ranging from mucocutaneous infection to life threatening invasive diseases. Recently there is a serious concern with increased resistance of antifungal drugs and its consequences. Thus, identification of Candida and its antifungal susceptibility testing has a paramount significance in the management of Candidal infections. The aim of the study was to determine antifungal susceptibility pattern of Candida by Mueller-Hinton agar media supplemented with glucose and methylene blue for disk diffusion testing of fluconazole, miconazole, clotrimazole, amphotericin B and nystatin. Methods: A total of 35 Candida species was isolated from 2000 clinical specimens over 6 month’s period from July 2016 to December 2016. Growths on Blood agar and chromogenic agar were evaluated for colony appearance and microscopic examination. Antifungal susceptibility testing was performed by disk diffusion using Mueller-Hinton agar supplemented with glucose and methylene blue. Results: Candida species were more sensitive to clotrimazole (88.58%) and amphotericin B (88.58%) followed by nystatin ((77.14%), miconazole (74.29%) whereas fluconazole showed the highest level of resistance (60%). Conclusions: The increase in resistance to fluconazole is of serious concern as it is the most commonly used azole for candidiasis. The sensitivity profile of Candida isolates will be helpful to choose appropriate antifungal agents, thus decreasing patient’s morbidity and mortality.
