check website morgreport dot com, under "the ultimate vector" for full info on rotifers. That is written by me. Remember, there is a difference between vector and cause...for example, a mosquito is the vector for malarria, but the mosquito doesn't cause malaria, it just transmits the pathogen. In this case, I am not sure if rotifers ARE the actual pathogen...but they can most certainly cause most of the symptoms of morgellons without need to involve any other agent.
