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 ...19938501590
distribution, prevalence and intensity of trichinella spiralis infection in furbearing mammals of pennsylvania.tongues from 1,170 raccoons, 384 opossums, 201 muskrats, 168 foxes (red and grey), 51 skunks, and 17 mink from pennsylvania were examined for trichinella spiralis larvae by peptic digestion. the overall prevalence of t. spiralis infection was 3.2%, varying in the carnivores from 2.6% in raccoons to 15.1% in red foxes; no muskrats were infected. prevalence varied regionally, being higher west of the susquehanna river, where, in the ridge and valley province, it reached 9%. the larval densities va ...19846387078
trichinosis surveillance, united states, 1986.trichinella spiralis is a parasite of carnivorous animals that causes the disease trichinosis. in the united states, people become infected by eating poorly cooked pork products or wild animal meat that is infected with the parasite. although fewer than 100 cases per year are reported to cdc, trichinosis continues to persist as a public health problem in this country. public health officials believe that the reported cases represent only a fraction of the total number of cases, since many of the ...19883148105
trichinella spiralis in the black bear (ursus americanus) of pennsylvania: distribution, prevalence and intensity of infection.samples of tongue or diaphragm from 2,056 black bears harvested in pennsylvania during the 1981-1983 hunting seasons were examined for larvae of trichinella spiralis by peptic digestion. sixteen males and 21 females were infected. the overall prevalence of infection was 1.8%. infected animals were distributed widely throughout the range of the bear in pennsylvania. in samples from infected bears, the geometric mean density of muscle larvae was 7.8 per g of tissue (lpg). there were neither sex- n ...19863951059
