Infections of Parahaemoproteus nettionis (JOHNSTON & CLELAND, 1909), recorded on the basis of the presence of mature gametocytes, were encountered in Cairina moschata. Biological tests under experimental conditions showed that Culex fatigans is not an efficient transmittor. Due to the poor survival of simulids and ceratopogonids in the laboratory, it was not possible to demonstrate the development of P. nettionis in these probable vectors. Inoculations of blood, or of suspensions of macerated organs from birds known to be parasitised, were inadequate for the transmission of the parasite. Inoculations of cortisone, splenectomy, or a combination of both, are ineffective as methods os aggravating the pathogenicity of P. nettionis.
