Experimental infections with the Tasmanian isolate of Trichinella pseudospiralis using a non-enzymatic recovery technique

Laboratory rats and mice, cats, brushtail possums (Trichosurus vulpecula), and 2 species of raptor (marsh harrier, Circus aeruginosus, and brown falcon, Falco berigora) were either infected orally with larvae of Trichinella pseudospiralis isolated by a non-enzymatic technique or by feeding infected muscle tissue. Muscle from a naturally infected Tasmanian devil (Sarcophilus harrisii) and an eastern quoll (Dasyurus viverrinus) resulted in infections in cats, rats, and marsh harriers. Similarly, larvae derived from feline muscle were infective for mice and a brown falcon. Infected muscle tissue from marsh harriers was also infective from the same species. The reproductive capacity index (RCI) for rats fed larvae from an eastern quoll was 34.5, whereas the RCI for mice infected with larvae derived from a cat was 31.6.
