Method Of Karyotype Determination For Cercaria: Application To Family Azygiidae (Trematoda), James Everett Mick

Masters Theses

The development of a method for karyotype determination of cercaria provides a basis for comparative karyotype analysis between cercaria and adult, possibly eliminating the need for infection experiments for positive identification of cercaria. Snails (Goniobasis livescens) were collected from below the spillway of Lake Charleston, on the Embarras River, near Charleston, Illinois. Of a total of 196 snails collected 42 (21.5%) were found to be infected with undetermined furcocyticercous cercariae. Infected snails were detected through isolation procedure. From the infected snails, emerged and non-emerged forms of the cercaria were recovered. Whole mounts of the cercaria were made and …
