University of Virginia School of Medicine researchers point out that amoebas produce a substance that ruptures immune defense cells that have engulfed the HIV virus. Once those cells are ruptured, the virus spreads throughout the system. In addition, as a result of the AIDS epidemic, the incidence of unusual parasitic diseases, such as Pneumocystis carinii pneumonia, cryptosporidiosis, and strongyloidiasis hava increased. These diseases can be fatal in the AIDS victim. A technique utilizing rectal mucus has also been perfected and can be administered by some physicians.
Many labs specialize in parasite testing.
It is important to note, however, that even if the stool sample is negative, many doctors will go ahead and treat anyway based on symptoms. There is no fool-proof diagnostic method when it comes to finding these uninvited guests. A parasite questionnaire may be helpful. As for treatment, some of the medications most commonly prescribed are Flagyl, Iodiquinol, Atabrine, and Vermox. Any one of these will usually rid the system of parasites if taken long enough.
