However, EU nations employ several strategies for detecting meat infected with "Trichinella spiralis". Virchow worked out the life cycle of a roundworm "Trichinella spiralis". Trichinosis (trichinellosis) is a disease caused by tissue-dwelling roundworms of the species "Trichinella spiralis". Wolves probably become infected with "Trichinella spiralis" by eating infected ungulates. The "Trichinella spiralis" draft genome became available in March, 2011. James Paget discovered the intestinal nematode "Trichinella spiralis" in humans in 1835. The major connection Virchow made was between Trichinella spiralis in swine and human infections. "Trichinella spiralis" can live the majority of its adult life in the intestines of humans.
