Thank Sezer. But for this, I have to inoculate the mice. I first need to know if the bacteria can be eliminated by urine or feces in order to avoid contamination of other mice because the laboratory animal facilitiy of my Institute doesn´t have barriers.

I offer to try immunocytochemical staning with first monoclonal antibodies strong specific for i.p. inoculated bacteria in feces after it base liquid cytology procedure.
