[The helminth and coccidial fauna of pheasants (Phasianus colchicus) in view of the specific environmental conditions in pheasantries and in the wild]

Abstract

Between October 1999 and January 2000 all together 151 male pheasants were examined for endoparasites. 33 one-year-old birds came from two pheasantries, the remaining 118 birds, aged between one and five years, were wildlife animals. The infestation extensy of all pheasants with endoparasites were 96.7%. A mostly low infestation with coccidia of the three species Eimeria (E.) phasiani, E. duodenalis and E. tetartooimia were detected in 41% of all birds. E. tetartooimia was found in Germany for the first time. In 67.5% of the pheasants the five different species of capillaria (Capillaria (C.) annulata, C. bursata, C. contorta, C. perforans, C. phasianina) and in 84.1% the nematode Heterakis gallinarum were present. Pheasants in the capture group showed higher infestation intensy and extensy. In 51.5% of the pheasants of the capture group Syngamus trachea was present. In one pheasant an acanthocephalus (Plagiorhynchus cylindraceus) was detected for the first time in Germany and in two pheasants a trematode of the genus Echinostoma was present.
