"One last thing about resistant critters. A person could easily have a resistant bunch not from what they did to get rid of the problem, BUT from a person that they initially contracted their eggs from. Meaning, an infected person could have exposed themselves to a lot of drug abuse, alcohol, chemicals or whatever to make the critters resistant and passes on the problem to an innocent victim. "
OH MY!! well that is a most scary thought, great something else to worry about..I hadnt thought of that one. How often do you think this happens?
