On the Differential Diagnosis of the Larvæ of some Helminth Parasites of Sheep and Goats

Abstract

In the majority of cases it is almost impossible to identify the species of helminths in our domestic stock by an examination of the eggs found in their droppings. In the case of sheep and goats, this is particularly so since these hosts harbour several worms with eggs which are, apparently, identical in shape, size and stage of development.
