Internal parasites of feral cats from the Tasmanian Midlands and King Island.

Eighty-six feral cats from a sheep grazing area in the Tasmanian Midlands and 21 from King Island were examined for internal parasites. Major food items in order of decreasing prevalence in stomach contents were insects, lizards, birds, rodents and frogs in the Midlands, and rodents, birds, insects, and lizards on King Island. Feral cats from the Midlands had 4 cestode, 7 nematode, 2 trematode and 3 protozoan parasites as follows: Spirometra erinacei (66.3%), Taenia taeniaeformis (2.3%), Dipylidium caninum (1.2%), Toxocara cati (86.0%), spiruroid nodules containing Cylicospirura felineus and Cyathospirura dasyuridis (57.0%), Ollulanus tricuspis (11.4%), Uncinaria stenocephala (2.3%), Aelurostrongylus abstrusus (39.2%), Capillaris aerophila (30.0%), Echinoparyphium sp (27.1%), Fibricola minor (6.8%), Isospora felis (12.7%), I. rivolta (5.4%), and Sarcocystis sp (1.8%). Antibodies to Toxoplasma gondii were found in 51 of 53 serums. Three cestode and 5 nematode parasites were found in cats from King Island: T. taeniaeformis (49.2%), D. caninum (23.8%), S. erinacei (19.0%), T. cati (90.5%), C. felineus (42.9%), C dasyuridis (9.5%), O. tricuspis (4.8%) and C. aerophila (9.5%). This is the first record of Cylicospirura felineus, Fibricola minor and Echinoparyphium sp in cats in Australia.
