Introduction: The emergence of resistant pathogenic microorganisms against conventional antimicrobials has become a global concern. To combat new and re-emerging infectious illnesses, new antimicrobial agents with different chemical structures and novel modes of action are required. Therefore, this study evaluated ethanolic extracts of Phyllanthus niruri for their antimicrobial activities against Candida species isolated from different clinical samples. Materials and Methods: This involved the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method for the identification of Candida species. The ethanolic extraction of P. niruri leaves was examined. The agar well diffusion method was used to determine the antifungal activity of the leaf extracts against standard American Type Culture Collection strains as well as clinical isolates of Candida species. Results: Using PCR-RFLP, Candida tropicalis was found to be the most prevalent species of Candida, followed by Candida albicans, Candida glabrata, Candida krusei and Candida parapsilosis. The ethanol extract of P. nirui leaves showed good activity against all the clinical and standard strains of Candida which were comparable to the standard drug fluconazole. The activity of P. niruri against C. albicans was highest followed by C. parapsilosis, C. tropicalis, C. glabrata and C. krusei at a concentration of 100 mg/ml. Conclusion: The findings of this study support the use of P. niruri plant to treat Candida infections, particularly fluconazole-resistant Candida species.
