Abstract
Endoparasite status of 27 red deer (25 calves and two hinds) culled in three consecutive months in a deer farm with endemic Fascioloides (F.) magna liver fluke infection in Bavaria, Germany was studied. Apart from F. magna recovered from the liver of 3 out of 27 animals, examination of the lungs, gastrointestinal tract and muscle samples revealed the presence of Dictyocaulus lungworms (26/27 animals), gastrointestinal nematodes (27/27 animals;11 species identified), and Sarcocystis cysts in the cardiac and/or diaphragmatic myocytes (7/27 animals). In addition, examination of rectum feces indicated the presence of protostrongylid nematode (Varestrongylus lungworms and Elaphostrongylus tissue worms;1/27 and 17/27 animals, respectively) and Eimeria coccidial infections (12/27 animals). Nematode parasite burdens averaged 61 Dictyocaulus lungworms (range, 0 to 554) and 950 gastrointestinal nematodes (range, 134 to 2649). At necropsy, there was a correlation between adult lungworm and fecal Dictyocaulus larval counts (p<0.0001) and adult strongylid nematode and fecal strongylid egg counts (p=0.0740). Total gastrointestinal nematode counts of the 25 calves did not show significant variability related to the month of harvest (November, December or January, respectively). However, the proportion of mucosal larval ostertagids increased significantly (p<0.05) in number from November to December and January. Dictyocaulus lungworm infection of the 25 calves showed a significant (p<0.05) reduction of lungworm counts with increasing age of the animals.
