Antimicrobial and Antibiofilm Activities of Copper(II)-1,10-phenanthroline-5,6-pione Against Commensal Bacteria and Fungi Responsible for Vaginal Microbiota Dysbiosis
Current microbiology(2023)
摘要
The disbalance of vaginal eubiotic microbiota can lead to overgrowth of Candida species and bacteria responsible for aerobic vaginitis, activating inflammatory pathways. The presence of Trichomonas vaginalis, a sexually transmitted protozoan pathogen, can be a predisposing factor for disordering the growth of bacterial/fungal pathogenic species due to the increase in pH and reduction of eubiotic microbiota. Herein, we evaluated the effects of the potent trichomonacidal compound, copper(II)-1,10-phenanthroline-5,6-dione (Cu-phendione), against pathogens responsible for candidiasis and aerobic vaginitis. Cu-phendione showed antimicrobial activity against Candida albicans , non- albicans Candida species ( C. glabrata , C. krusei , C. parapsilosis, and C. tropicalis ) and Gram-negative ( Escherichia coli ) and Gram-positive ( Staphylococcus aureus , Enterococcus faecalis, and Streptococcus agalactiae ) bacteria. Moreover, Cu-phendione was able to interfere with the fungal biofilm formation. These results highlight the antimicrobial potential of Cu-phendione against bacterial and fungal strains of vaginitis-causing infectious agents.
