The paramphistomes (Trematoda) of Australian ruminants. 3. The life-history of calicophoron calicophorum (Fischoeder) Nasmark.

Abstract

A description of the life-history of Calicophoron calicophorum (Fischoeder 1901) Nasmark 1937 is given, and the larval stages of this parasite within the snail intermediate host Pygmanisus pelorius (Iredale 1943) are described. The pre-patent period for this fluke in a lamb was found to be in the vicinity of 80-95 days.
