METHODS OF TEACHING PARASITOLOGY

The fact that animal parasites are important as disease produc- 
ing agents has been known for a great many years. Thought, 
consideration, study, and emphasis on the question of parasitism 
have come in waves; at times it was looked upon as one of the 
most important factors to be dealt with, while at other times or 
periods it has received almost no attention and parasites have been 
looked upon as more or less unimportant as disease producing 
agents. But the necessity for the protection of our livestock from 
disease has grown, being governed largely by the supply and de- 
mand, together with the rearing of animals under more or less 
intensive conditions, the modern commercial method of handling 
animals for food purposes, the very general interchange of breed- 
ing stock, the numerous stock shows, and other conditions that 
make possible the spread of parasitic diseases. Further, it has 
been proven that many parasites are carriers, directly or indirectly, 
of the causes of specific diseases and thus parasites as well as all 
classes of disease-producing agents have of necessity received 
attention. While the full importance of animal parasites was 
not fully appreciated until more or less recent years, our know- 
ledge regarding them has been gradually increased, as a result both 
of natural infestation and of experimental work, until today we 
have come to understand the very great importance of parasitism 
and animal parasites in relation to the cause and spread of disease 
among both man and animals. 
Studies in parasitology, as strictly veterinary, have been intro- 
duced into practically all courses in veterinary medicine within the 
last fifteen to twenty years. This, together with the great amount 
of experimental work and investigation being done and the gen- 
eral discussion that is taking place on the question of animal 
parasites, speaks fully for the importance of this subject and the 
attention that it is receiving by the medical world. 
The object of this report is to briefly outline a systematic plan 
for a method of teaching parasitology to veterinary students with
