An Improved Method of Separating Eelworm Cysts from Débris

Abstract

In order to carry out quantitative experiments on eelworms of the cyst forming species it is often necessary to obtain a known number of cysts from soil. The extraction of the cysts from the soil, their separation from débris which is always present, and their enumeration always take up much time. By use of the simple apparatus described below cyst separation and counting can be greatly accelerated.
