Hi,

I have been collecting information on the possible methods of infection 
of people by E.coli. There is a recorded instance of infection through 
swimming in a lake and drinking the water 
http:/vm.cfsan.fda.gov/%7Emow/lakeo157.html  
It has been suggested that the infective dose could be extremely small. 
If one swallows bacteria, why don't the stomach acids kill them?
Would it be possible, while swimming, to aquire the infection anally 
instead of by mouth?
How is the organism eventually rejected by the body without eliminating 
the normal E.coli?

This is my first contact with a newsgroup. I hope it works.

Thanks
