Abstract
Conclusions
It is hoped that a means has now been provided, through use of hamsters, to study more intensively the incitant of this disease and to determine its possible relationship to the toxic principle reported by Stein-haus(4) in D. andersoni eggs. Ecologic and/ or genetic factors may be influential, but it is pertinent that reared progeny of paralysis-producing ticks have now induced experimental disease. In spite of successful transmission by partially fed ticks from paralyzed animals in many of the above experiments, individual female ticks that produced paralysis in 3 child patients of Drs. Barmeyer and Adlerson of Missoula completed engorgement and mated on 2 dogs and 1 hamster, respectively, in 2 to 4 days without reproducing paralytic signs in these hosts. These observations indicate that hamsters are the animals of choice for the study of tick paralysis.
