| biochemical, biological, and genetic characterization of a sylvatic isolate of trichinella. | biological, biochemical, and genetic relationships of trichinella isolates were assessed and compared from 3 species of illinois fur-bearing mammals. tongue muscle collected from 1987 through 1989 from 323 raccoons (procyon lotor), 9 red fox (vulpes fulva), and 1 coyote (canis latrans) were digested and trichinella muscle larval prevalences and mean intensities (larvae/g) determined. the prevalence and mean intensity of tongue muscle-stage larvae were 2.8% and 44.4% and 326 and 2 larvae/g for ra ... | 1993 | 8501590 |
