Context: Oral candidiasis is the most common oral opportunistic infection has seen in the immunocompromised patients. Apart from C. albicans the non-Candida albicans Candida species, which are less susceptible to the commonly used antifungal drugs are major etiological agent for candidiasis. Thus, the treatment strategy for candidiasis should be different in case of multiple species infection. Aims: The aim of this present study is to compare the antifungal susceptibility patterns of Candida species isolated from mono species and multiple species oral Candidal carriage. Materials and Methods: The species of Candida, isolated from mono and multiple species oral Candidal carriage of the healthy and immunocompromised patients were used for the experiment. Antifungal susceptibility test was performed by using disk diffusion susceptibility method on Methylene blue Glucose- Mueller-Hinton agar. Statistical Analysis Used: Paired student's t-test. Results: In this, present study, variability in antibiogram of Candida species isolated from mono species and the corresponding species isolated from multiple species combinations were reported. The susceptibility ranking for antifungal drugs for the strain isolated from mono species OPC (C. albicans > C.tropicalis > C. glabrata > C.krusei) and for the strains isolated from multiple species combination (C. albicans > C. glabrata > C.krusei > C.tropicalis) for mean of the five antifungal drugs combined were reported. Species of C. albicans and C. tropicalis were reported more resistant towards anti fungal agents when these present in mono-species condition, whereas; C. krusei and C. glabrata were more susceptible when these present in mono-species condition. Polyenes (amphotericin-B and nystatin) compounds were found to be most effective than azoles against Candida spp. isolated from multi-species lesions as none of the strain were shown resistant towards these drugs, conversely; a significant fraction of C. tropicalis and C. albicans isolated from mono-species lesion were shown resistant toward polyenes compound tested. Conclusions: The findings of this study shows statistically insignificant diverse antifungal susceptibility pattern of Candida species isolated from mono and multiple species Oropharyngeal Candidiasis combinations.
