Epidemiology of trichinellosis in lynx in Finland
Abstract Three hundred and twenty seven European lynx ( Lynx lynx ) were examined for Trichinella sp. larvae using the muscle digestion method. The animals were of both sexes, various ages, and collected between 1989 and 1994 in different locations in Finland. Forty percent of them (132) were found...
