| 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 |
| molecular and biologic characteristics of toxoplasma gondii isolates from wildlife in the united states. | toxoplasma gondii isolates can be grouped into 3 genetic lineages. type i isolates are considered more virulent in outbred mice and have been isolated predominantly from clinical cases of human toxoplasmosis, whereas types ii and iii isolates are considered less virulent for mice and are found in humans and food animals. little is known of genotypes of t. gondii isolates from wild animals. in the present report, genotypes of isolates of t. gondii from wildlife in the united states are described. ... | 2004 | 15040668 |
| survey of antibodies to leishmania spp. in wild canids from pennsylvania and tennessee. | visceral leishmaniasis (vl) is a zoonosis with worldwide distribution. infections with the leishmania donovani complex, including leishmania infantum, cause the vl. domestic dogs are the most important reservoir host for human vl, and wild canids are also susceptible. in the united states, infections with l. infantum are common in the foxhound dog breed. little information is available regarding l. infantum in wild canids in the unites states. sera from 11 foxes and 256 coyotes originating in pe ... | 2013 | 24450086 |
| genotyping toxoplasma gondii from wildlife in pennsylvania and identification of natural recombinants virulent to mice. | recent studies indicated the predominance of toxoplasma gondii haplogroup 12 in wildlife in the usa. however, still little is known of the genetic diversity of this parasite circulating in wildlife. in the present study, we tested coyotes (canis latrans), red foxes (vulpes vulpes), white-tailed deer (odocoileus virginianus), and geese (branta canadensis) from the state of pennsylvania for t. gondii infection. antibodies to t. gondii were found in 160 of 367 animals, including 92 (34.5%) of 266 c ... | 2014 | 24332401 |
| serologic survey of antibodies to trypanosoma cruzi in coyotes and red foxes from pennsylvania and tennessee. | trypanosoma cruzi is a zoonotic parasite of humans and other mammalian hosts with distribution throughout the americas. domestic and wild canine species are reservoirs for human t. cruzi infections. the present study examined the prevalence of antibodies to t. cruzi in wild canids from the united states. sera from 13 red foxes (vulpes vulpes) and 263 coyotes (canis latrans), originating in pennsylvania and tennessee, were assayed for antibodies to t. cruzi with immunochromatographic tests. antib ... | 2014 | 25632700 |
| genetic characterization of sarcoptes scabiei from black bears (ursus americanus) and other hosts in eastern united states. | since the early 1990s there has been an increase in the number of cases and geographic expansion of severe mange in the black bear (ursus americanus) population in pennsylvania. although there are 3 species of mites associated with mange in bears, sarcoptes scabiei has been identified as the etiologic agent in these pennsylvania cases. historically s. scabiei-associated mange in bears has been uncommon and sporadic although it is widespread and relatively common in canid populations. to better u ... | 2017 | 28639466 |
| an aerial baiting system for the distribution of attenuated or recombinant rabies vaccines for foxes, raccoons, and skunks. | an aerial baiting system was developed to deliver oral rabies vaccines to wild carnivore vectors of rabies, e.g., red fox, striped skunk, and raccoon. the bait consists of a polyethylene bag that contains either a 30-g hamburger ball or a 25-ml cube of polyurethane sponge coated with a wax-beef tallow mixture containing 100-150 mg of tetracycline as a biomarker. attractants used with the sponge were added to the bag (e.g., liver slurry, cheeses, fish oils, or fruits). baits (greater than 80,000) ... | 2006 | 3206077 |
