| sarcocystis and other coccidia in foxes and other wild carnivores from montana. | sarcocystis spp sporocysts were found in feces of 10.1% of 198 red foxes (vulpes vulpes), in 3.2% of 61 bobcats (lynx rufus), in 16.6% of 12 mountain lions (felis concolor), in 16.6% of 6 fisher (martes pennanti), and in none of 20 wolverines (gulo gulo), 4 mink (mustela vison), or 10 raccoons (procyon lotor). sarcocystis muris and toxoplasma gondii were not found in laboratory mice inoculated with feces of bobcats and mountain lions. | 1982 | 6816776 |
| seroprevalence of toxoplasma gondii in danish farmed mink (mustela vison s.). | one hundred and ninety-five mink sera randomly selected from 17 danish mink farms were evaluated for the presence of toxoplasma gondii antibodies in the latex agglutination test. six (3%) sera contained t. gondii antibodies in titres of 1:64 or more. the estimated 3% prevalence means that 300,000 mink out of a total mink population of ten million might be infected with toxoplasma gondii. this large number of possible sero-positive mink in denmark indicates that there exists a potential risk of a ... | 1994 | 8091606 |
| an outbreak of toxoplasmosis in farmed mink (mustela vison s.). | a large wisconsin mink (mustela vison) farm experienced an outbreak of toxoplasmosis in the spring of 1999 following an outbreak of canine distemper during the previous fall. major clinical signs for pregnant females included reduced feed consumption, abortions, and stillborn kits; kits < or =3 weeks old experienced ataxia and mortality. of 7,800 females, 1,976 (26%) lost their entire litter either from abortion or neonatal mortality. kit mortality from 7 days to 3 weeks of age was 3,300, and ov ... | 2001 | 11482603 |
| toxoplasmosis in a free-ranging mink. | a free-ranging mink (mustela vison), estimated to be 3 mo old, was found on the campus of michigan state university, east lansing, michigan; it exhibited clinical signs of left hind limb lameness, ataxia, head tremors, and bilateral blindness. histologically, the animal had a mild, nonsuppurative meningoencephalitis and severe chorioretinitis with intralesional bradyzoites and tachyzoites. protozoal organisms were identified as toxoplasma gondii based on histology, immunohistochemistry, and poly ... | 2006 | 17255457 |
| molecular detection and genetic characterization of toxoplasma gondii in farmed minks (neovison vison) in northern china by pcr-rflp. | toxoplasma gondii is a worldwide prevalent parasite, affecting a wide range of mammals and human beings. little information is available about the distribution of genetic diversity of t. gondii infection in minks (neovison vison). this study was conducted to estimate the prevalence and genetic characterization of t. gondii isolates from minks in china. a total of 418 minks brain tissue samples were collected from jilin and hebei provinces, northern china. genomic dna were extracted and assayed f ... | 2016 | 27806069 |
| serology and protein electrophoresis for evidence of exposure to 12 mink pathogens in free-ranging american mink (neovison vison) in argentina. | basic pathologic characteristics for farmed minks were previously reported worldwide. however, its status in the wild has not been studied in detail. | 2017 | 28635524 |
| seroprevalence and risk factors of toxoplasma gondii infection in farmed minks (neovison vison) in northeastern and eastern china. | toxoplasma gondii is an important intracellular parasite, which can infect endothermic vertebrate animals, including minks (neovison vison). however, information on t. gondii infection in minks in china is limited. therefore, we investigated the seroprevalence and risk factors of t. gondii infection in minks in northeastern and eastern china. a total of 1499 mink blood samples were randomly collected from eight cities between march 2014 and january 2015 in northeastern and eastern china, and ant ... | 2016 | 27166868 |
| investigations into shaking mink syndrome: an encephalomyelitis of unknown cause in farmed mink (mustela vison) kits in scandinavia. | an apparently novel neurological disease clinically characterized by shaking, tremors, seizures, staggering gait, and ataxia was first observed in farmed mink kits in denmark in 2000 and subsequently in sweden, denmark, and finland in 2001, and again in denmark in 2002. lymphoplasmacytic encephalomyelitis was found in the affected kits. the lesions were most severe in the brainstem and cerebellum and consisted of neuronal degeneration and necrosis, neuronophagia, focal and diffuse gliosis, periv ... | 2004 | 15305741 |
| experimental infection with toxoplasma gondii in farmed mink (mustela vison s.). | live toxoplasma gondii tissue cysts (strain 119) were administered orally to five mink (mustela vison s.) and five mink were inoculated with a suspension of ultrasonicated toxoplasma gondii trophozoites (rh-strain). seroconversion was observed in all animals administered live t. gondii cysts indicating that infection was established. likewise seroconversion was observed in three out of four animals administered ultrasonicated t. gondii trophozoites. faecal shedding of oocysts of t. gondii was no ... | 1993 | 8493756 |
| prevalence of antibodies to toxoplasma gondii in wild mammals of missouri and east central kansas: biologic and ecologic considerations of transmission. | sera from 273 wild mammals from missouri and kansas (usa), collected between december 1974 and december 1987, were tested for the presence of antibodies to toxoplasma gondii using the sabin-feldman dye test. sixty-five (24%) had antibodies at titers of > or = 1:8, including 38 (66%) of 58 carnivores, 14 (15%) of 94 omnivores, 13 (11%) of 117 herbivores, and none of four insectivores. the prevalence of antibodies in mice (mus musculus and peromyscus spp.) and rats (rattus norvegicus and sigmodon ... | 1995 | 7563419 |
| risk factors for toxoplasma gondii exposure in semiaquatic mammals in a freshwater ecosystem. | we assessed risk factors for toxoplasma gondii exposure in semiaquatic mammals in east-central illinois, us. this agricultural region has extensive drainage systems that could potentially transport t. gondii oocysts into the watershed. we used muskrats (ondatra zibethicus) and american mink (neovison vison) as sentinels of watershed contamination. we predicted individuals from larger subwatersheds would more likely be antibody-positive for t. gondii, as they were exposed to drainage from larger ... | 2015 | 25574808 |
| toxoplasma gondii in feral american minks at the maullín river, chile. | american mink (neovison vison) is a widely distributed invasive species in southern chile. thirty four feral minks were trapped at two distinct sites (rural and peri-urban), diet analyzed and toxoplasma gondii exposure compared using pcr and specific antibodies. serum samples were evaluated using a commercial latex agglutination test where a titer ≥ 1:32 was considered positive. of 30 mink analyzed, 21 (70%) were positive to t. gondii antibodies, with titers ranging from 1:32 to 1:2048. as expec ... | 2010 | 20965660 |
