An Immobilization Reaction against Balantidium coli


AN immunological test, the immobilization reaction, has been found to be positive for a number of protozoa1. I have found it useful in differentiating various species of Entamoeba and strains of E. histolytica2. However, it is with Tetrahymena3 and Paramecium4 that the reaction has been studied in greatest detail. Against Paramecium it is a highly specific and sensitive test. In view of these positive results with various ciliates, it was thought of interest to determine whether a positive reaction could be obtained with Balantidium coli.
