Trichinella spiralis infected rat carcasses were incubated for 6 weeks in several animal feeds to assess how long Trichinella can present a risk for an outbreak in contaminated feeds. In groups of 6, 24 infected target rats were placed in silage, grained barley, propionic acid-preserved feed, and also into simulated pasture conditions. Test environments… (More)
The predilection muscles of Trichinella spiralis and T. nativa were studied in 2 experimental groups of 6 raccoon dogs (Nyctereutes procyonoides), the third group serving as a control for clinical signs. The infection dose for both parasites was 1 larva/g body weight. After 12 weeks, the animals were euthanized and 13 sampling sites were analysed by the… (More)
From Parasite infections of domestic animals in the Nordic countries – emerging threats and challenges.
A total of nine Trichinella nativa isolates were compared by amplified fragment length polymorphism (AFLP). Four hundred nanograms of genomic DNA from a pool of 10--20 larvae were digested using HindIII and MseI restriction endonucleases. Of the 16 primer combinations initially tested, Hind-C and Mse-C primers showed rich polymorphism with approximately… (More)
