ABSTRACT

Introduction: In mycoses, resistance to antifungals increases due to incorrect diagnosis and treatment. Therefore, surveillance and monitoring of resistant strains has been suggested to ensure adequate therapy.
Objective: To determine the Candida species and the resistance profile to fluconazole and voriconazole presented by the isolates obtained from samples stored during the months of December 2017 and March 2018 from patients coming from the Laboratory of the Regional Hospital "Miguel Ángel Mariscal Llerena" in the department of Ayacucho, Peru.
Material and Methods: Cross-sectional descriptive study in which 110 strains of Candida sp were isolated and stored for a period of four (04) months, and processed by standardized methods approved by the Ministry of Health (MINSA) and the National Institute of Health (INS) of Peru related to the diagnosis of etiological agents of human mycosis and antifungal sensitivity with the standardized methods of the Clinical Laboratory Standard Institute (CLSI).
Results: C. albicans was observed in 86,4 % of isolates, followed by C. glabrata (9,1 %), C. parapsilosis (2,7 %), and 0,9 % of C. tropicalis and C. krusei; 10,5 % of C. albicans was resistant to fluconazole and voriconazole with MIC ≥ 128 μg/mL and ≥ 16 μg/mL respectively, while 20 % of C. glabrata showed dose dependent sensitivity and 10 % resistance to fluconazole.
Conclusions: There is a wide variety of Candida species, with C. albicans being the most common, followed by C. glabrata, with a higher percentage of isolation compared to other species. It can be seen that these species have considerable degrees of vulnerability to the application of drugs such as fluconazole and voriconazole.
