An investigation of the hypothesis that Haemoproteus is not transmitted in the Delta Marsh area with related notes on leucocytozoon

Abstract

During the summers of 1959 and 1960 evidence was collected supporting the concept that, while Haemoproteus and Leucocytozoon are present as parasites of ducks in the Delta Marsh area, transmission does not occur locally. This was substantiated by two facts - firstly the absence of suitable insect vectors and secondly the lack of transmission to experimental animals raised in the hatchery and transported to various locations around the marsh.
