I am doing some studies with effect of antibiotics on E.coli after infection of Mammalian cells. I'm specifically looking at MCF-7 cell lines. Could anyone give me some insight into how long E. coli takes to adhere/infect to mammalian cells?
I was having a doubt that If you are infecting mammalian cells with E.coli then you cant distinguish whether it is contamination or results of transfection. If I am wrong can you explain me exactly what is your aim?
