Abstract
Background: The most significant sexually transmissible fungal disease, semen
candidiasis, is caused by Candida albicans and impacts male reproductive potential. Actinomycetes
are a group of microorganisms that could be isolated from various habitats and
used for the biosynthesis of various nanoparticles with biomedical applications.
Objective: Testing antifungal activity of biosynthesized Ag nanoparticles versus isolated
C. albicans from semen as well as its anticancer activity versus the CaCO2 cell line.
Methods: Screening 17 isolated actinomycetes for the biosynthesis of Ag nanoparticle biosynthesis.
Characterization of biosynthesized nanoparticles, testing its anti-Candida albicans,
and antitumor activity.
Results: Streptomyces griseus was the isolate that identified silver nanoparticles using UV,
FTIR, XRD and TEM. Biosynthesized nanoparticles have promising anti-Candida albicans
with MIC (125 ± 0.8) μg/ml and accelerate apoptotic rate versus CaCO2 cells (IC50 =
7.30 ± 0.54 μg/ml) with minimal toxicity (CC50 = 142.74 ± 4.71 μg/ml) versus Vero cells.
Conclusion: Certain actinomycetes could be used for the biosynthesis of nanoparticles
with successive antifungal and anticancer activity to be verified by in vivo studies.
Keywords:
Streptomyces griseus, Candida albicans, nanoparticles, antifungal action, antitumor impact, Ag-NPs.
