Can Antibiotic Resistance Be Altered By Alcohol Exposure?

Angela W asked:


I'm performing an experiment, where I'm introducing an isolate to 5% concentrations of two alcohols and then seeing if antibiotic resistance is affected. We had to write a small paragraph indicating the significance of the project.

I said that exposure to alcohol would weaken the cell's defenses against the antibiotic and lead to their vulnerability.

My teacher wrote on my paper that this was "not the mechanism."

I have tried to find some sources to determine what the mechanism could actually be but I have been unsuccessful. All I can find are articles about drinking alcohols while taking antibiotics.

Any guidance would be greatly appreciated.

Thanks!
