| antibodies to borrelia sp. in wild foxes and coyotes from wisconsin and minnesota. | serum samples from 93 red foxes (vulpes vulpes) and nine gray foxes (urocyon cinereoargenteus) trapped in wisconsin and 23 coyotes (canis latrans) trapped in wisconsin and minnesota were tested for antibodies to borrelia sp. with an indirect fluorescent antibody test which used borrelia burgdorferi as the whole-cell antigen. seven red foxes (8%) and two coyotes (9%) had antibody titers greater than or equal to 1:64. all the positive samples were from areas known to be endemic for human lyme dise ... | 1989 | 2644451 |
| rabies surveillance in the united states during 2007. | summary: during 2007, 49 states and puerto rico reported 7,258 cases of rabies in animals and 1 case in a human to the cdc, representing a 4.6% increase from the 6,940 cases in animals and 3 cases in humans reported in 2006. approximately 93% of the cases were in wildlife, and 7% were in domestic animals. relative contributions by the major animal groups were as follows: 2,659 raccoons (36.6%), 1,973 bats (27.2%), 1,478 skunks (20.4%), 489 foxes (6.7%), 274 cats (3.8%), 93 dogs (1.3%), and 57 ca ... | 2008 | 18795848 |
| isolation of viable neospora caninum from brains of wild gray wolves (canis lupus). | neospora caninum is a common cause of abortion in cattle worldwide. canids, including the dog and the dingo (canis familiaris), the coyote (canis latrans), and the gray wolf (canis lupus) are its definitive hosts that can excrete environmentally resistant oocysts in the environment, but also can act as intermediate hosts, harboring tissue stages of the parasite. in an attempt to isolate viable n. caninum from tissues of naturally infected wolves, brain and heart tissue from 109 wolves from minne ... | 2014 | 24522164 |
| antibody detection and molecular characterization of toxoplasma gondii from bobcats (lynx rufus), domestic cats (felis catus), and wildlife from minnesota, usa. | little is known of the epidemiology of toxoplasmosis in minnesota. here, we evaluated toxoplasma gondii infection in 50 wild bobcats (lynx rufus) and 75 other animals on/near 10 cattle farms. antibodies to t. gondii were assayed in serum samples or tissue fluids by the modified agglutination test (mat, cut-off 1:25). twenty nine of 50 bobcats and 15 of 41 wildlife trapped on the vicinity of 10 farms and nine of 16 adult domestic cats (felis catus) and six of 14 domestic dogs resident on farms we ... | 2016 | 26824935 |
| sympatric wolf and coyote populations of the western great lakes region are reproductively isolated. | interpretation of the genetic composition and taxonomic history of wolves in the western great lakes region (wglr) of the united states has long been debated and has become more important to their conservation given the recent changes in their status under the endangered species act. currently, the two competing hypotheses on wglr wolves are that they resulted from hybridization between (i) grey wolves (canis lupus) and western coyotes (c. latrans) or (ii) between grey wolves and eastern wolves ... | 2010 | 20854277 |
| wolves-coyotes-foxes: a cascade among carnivores. | due to the widespread eradication of large canids and felids, top predators in many terrestrial ecosystems are now medium-sized carnivores such as coyotes. coyotes have been shown to increase songbird and rodent abundance and diversity by suppressing populations of small carnivores such as domestic cats and foxes. the restoration of gray wolves to many parts of north america, however, could alter this interaction chain. here we use a 30-year time series of wolf, coyote, and fox relative abundanc ... | 2012 | 22690642 |
