- In vitro anti-Acanthamoeba activity of Marmara Sea-derived Actinomycetes and cytotoxicity of human HaCaT and MCF-7 cell lines.

With the global incidence of Acanthamoeba infections increasing and no specific treatment currently available, research into novel anti-Acanthamoeba agents remains essential. Similarly, cancer cases are also rising worldwide, and effective treatments continue to be a major challenge. In this context, the present study aimed to investigate the anti-Acanthamoeba and anticancer activities of marine Actinomycetes isolated from Türkiye. Fifteen Actinomycetes cell-free supernatants were prepared and used in this study. To evaluate anti-Acanthamoeba effects, Acanthamoeba strains isolated from swimming pools in our previous research as well as standard Acanthamoeba castellanii (A. castellanii ) strains, were employed. The MCF-7 breast cancer cell line and the HaCaT human keratinocyte cell line served as models for assessing cytotoxic activity. Three Actinomycetes supernatants (20%) demonstrated strong inhibitory activity against all tested Acanthamoeba strains. MCF-7 cells were found to be more sensitive to one supernatant across all tested dilutions. These findings suggest that marine-derived Actinomycetes, are promising candidates for Acanthamoeba trophozoites. Moreover, the results may guide future research on cytotoxic bacterial metabolites produced by marine Actinomycetes.
