Abstract
Introduction: Candida spp. are opportunistic yeasts found in various environments, including soil. Some species can cause human infections, particularly in immunocompromised individuals. Their therapeutic management is challenging due to resistance reported in numerous studies. This study aimed to explore the diversity and antifungal susceptibility of Candida spp. strains isolated from soils in Ouagadougou (Burkina Faso). Methods: A cross-sectional study conducted from August 2019 to February 2021. The soil sampling sites were chosen from uninhabited areas of the city of Ouagadougou. At each site, four composite subsamples of approximately 50 g of soil were taken from less than 10 cm deep by removing the top three (3) centimeters with a sterile spatula and placed in a sterile container. Candida species were identified using a chromogenic medium (CAN ID2) and Matrix-Assisted Laser Desorption/Ionization Time-of-Flight (MALDI-TOF) spectrometry. Antifungal susceptibility was performed by disk diffusion method and classified as susceptible, susceptible dose-dependent and resistant. Results: A total of 38 strains belonging to 6 species of the genus Candida were isolated. These species in order of frequency were Candida tropicalis (76.32%), Candida glabrata (10.53%), C. lusinatinae (5.26%), C. krusei (2.63%), C. kefyr (2.63%), and C. orthopsilosis (2.63%). The strains showed high resistance to itraconazole (93.2%) and fluconazole (48.3%) among azoles. For polyenes, the resistance of the strains was noted with amphotericin B with a high rate of 89.7%. Conclusions: This study reveals that the soils of the city of Ouagadougou harbor Candida spp. yeast species and can be a source of contamination for humans. These yeasts are resistant to some antifungals. This indicates the need to monitor their susceptibility to common antifungals.
