Mollicutes contaminations of cellular models can have marked effects on gene expression and cell behaviour invitro leading to the production of unreliable data, unsafe biopharmaceutical drugs or to the loss of cell culture itself. Fortunately, irreplaceable cell culture can be cured by decontamination with the specific antibiotic regimen. Here, we describe the treatment of 35 mycoplasma-positive cell lines by the use of the novel antibiotic Mycozap® as well as evaluate its eradication performance versus the well-known routinely employed BM-Cyclins and fluoroquinolones molecules (175 treatments). Our data evidenced: i) the permanent elimination of mycoplasma infection by MycoZap®, MRA, Enrofloxacin, Ciprofloxacin and BM-Cyclins in 46%, 29%, 40%, 43%, and 57% of the cultures, respectively; ii) a significant correlation between MRA and Ciprofloxacin eradication profile, as determined by the Spearman correlation coefficient (r=0.3469, p®, Ciprofloxacin, Enrofloxacin, BM-Cyclin 1-2 antibiotic regimen, with the MRA exclusion; iv) the MycoZap® effectiveness even in case of a mycoplasmal load higher than 50CFU/mL, as for SH-SY5Y and Neuro2A cells.In conclusion, we want to suggest an optimized antibiotic panel to get 100% mycoplasma-clearance especially in case of unique or treatment-resistant cellular models.
