| rabies surveillance in the united states during 1991. | in 1991, 49 states, the district of columbia, and puerto rico reported 6,972 cases of rabies in nonhuman animals and 3 cases in human beings to the centers for disease control. ninety-one percent (6,354 cases) were wild animals, whereas 8.9% (618 cases) were domestic species. the total number of reported cases of rabies increased 42.9% over that of 1990 (4,881 cases), with most of the increase resulting from continued spread of the epizootic of rabies in raccoons in the mid-atlantic and northeas ... | 1992 | 1483899 |

| prevalence of antibodies to neospora caninum, sarcocystis neurona, and toxoplasma gondii in wild horses from central wyoming. | sarcocystis neurona, neospora caninum, n. hughesi, and toxoplasma gondii are 4 related coccidians considered to be associated with encephalomyelitis in horses. the source of infection for n. hughesi is unknown, whereas opossums, dogs, and cats are the definitive hosts for s. neurona, n. caninum, and t. gondii, respectively. seroprevalence of these coccidians in 276 wild horses from central wyoming outside the known range of the opossum (didelphis virginiana) was determined. antibodies to t. gond ... | 2003 | 14533680 |

| bartonella and rickettsia from fleas (siphonaptera: ceratophyllidae) of prairie dogs (cynomys spp.) from the western united states. | fleas of prairie dogs have been implicated in the transmission of bartonella spp. we used pcr to test dna extracts from 47 fleas of prairie dogs from 6 states. we amplified dna from 5 unique genotypes of bartonella spp. and 1 rickettsia sp. from 12 fleas collected in north dakota, oklahoma, texas, and wyoming. sequences from the bartonella spp. were similar, but not identical, to those from prairie dogs and their fleas in colorado. | 2007 | 17918386 |
| survey of 11 western states for heartworm (dirofilaria immitis) infection, heartworm diagnostic and prevention protocols, and fecal examination protocols for gastrointestinal parasites. | heartworm infection in dogs and cats in the western united states is a fairly new phenomenon, and for this reason it is often considered to be of minimal significance. the purpose of this survey was to collect data from 11 western states (arizona, california, colorado, idaho, montana, nevada, new mexico, oregon, utah, washington, and wyoming) in an effort to assess awareness of heartworm disease and identify areas in which improvement in understanding is needed. to accomplish this goal, veterina ... | 2007 | 18183548 |
| prevalence of yersinia pestis in rodents and fleas associated with black-tailed prairie dogs (cynomys ludovicianus) at thunder basin national grassland, wyoming. | rodents (and their fleas) that are associated with prairie dogs are considered important for the maintenance and transmission of the bacterium (yersinia pestis) that causes plague. our goal was to identify rodent and flea species that were potentially involved in a plague epizootic in black-tailed prairie dogs at thunder basin national grassland. we collected blood samples and ectoparasites from rodents trapped at off- and on-colony grids at thunder basin national grassland between 2002 and 2004 ... | 2008 | 18689663 |
| bartonella spp. dna in cardiac tissues from dogs in colorado and wyoming. | background: several bartonella species (spp.) have been identified in dogs diagnosed with infectious endocarditis (ie) or myocarditis. objective: to interrogate cardiac tissues of dogs with suspected ie for the presence of bartonella spp. dna of dogs in the rocky mountain states. animals: nine dogs with a clinical diagnosis of endocarditis from january 1990 to june 2008 were included. methods: in this retrospective study, medical records at the veterinary teaching hospital were searched. animals ... | 2011 | 21539606 |
| plague in a complex of white-tailed prairie dogs and associated small mammals in wyoming. | fleas were collected from white-tailed prairie dogs (cynomys leucurus) and other small mammals trapped on six grids during a field study near meeteetse (wyoming, usa) in 1989 and 1990 to investigate the dynamics of plague in this rodent population. fleas were identified and tested for yersinia pestis by mouse inoculation. yersinia pestis-positive fleas were found on prairie dogs and in their burrows. flea species on prairie dogs changed from spring to late summer. white-tailed prairie dog number ... | 1997 | 9391955 |
| eimeria spp. (apicomplexa: eimeriidae) from black- and white-tailed prairie dogs (cynomys ludovicianus and cynomys leucurus) in central and southeast wyoming. | feces collected from live-trapped black- (cynomys ludovicianus) and white-tailed prairie dogs (cynomys leucurus) from central and southeastern wyoming were examined to determine the presence and prevalence of eimerian species. six species (eimeria adaensis [black-tailed prairie dog prevalence = 33%, white-tailed prairie dog prevalence = 51%], eimeria beecheyi [8%, 28%], eimeria callosper-mophili [64%, 71%], eimeria lateralis [3%, 7%], eimeria morainensis [19%, 8%], and eimeria spermophili [2%, 1 ... | 1997 | 9057719 |
| plague in a black-footed ferret (mustela nigripes). | diagnosis of sylvatic plague in a captive black-footed ferret (mustela nigripes) was based on gross and microscopic lesions, fluorescent antibody tests, culture of yersinia pestis, and immunohistochemistry. gross lesions consisted of acute hemorrhage and necrosis associated with cervical and mesenteric lymph nodes, subcutaneous hemorrhages, and pulmonary edema. acute edema, hemorrhage, and necrosis with numerous bacteria in blood vessels and sinusoids characterized microscopic lesions. occurrenc ... | 1994 | 7760495 |
| a plague epizootic in the white-tailed prairie dogs (cynomys leucurus) of meeteetse, wyoming. | surveillance for sylvatic plague (yersinia pestis) was conducted near meeteetse, wyoming (usa) from 24 may to 14 june 1985. ten species of fleas were collected from white-tailed prairie dogs (cynomys leucurus), and from their burrows and associated rodents. five of these flea species and two adult prairie dogs were positive for plague. the progression of this plague epizootic appeared to be slower and the intensity was less than in previous epizootics in other prairie dog colonies. the plague ep ... | 1988 | 3411698 |
| Structural and Functional Properties of Glycerol-3-Phosphate Dehydrogenase from a Mammalian Hibernator. | Glycerol-3-phosphate dehydrogenase (G3PDH; E.C.1.1.1.8) was purified from liver and skeletal muscle of black-tailed prairie dogs (Cynomys ludivicianus), a hibernating species. Native and subunit molecular masses of the dimeric enzyme were 77 and 40 kD, respectively, and both tissues contained a single isozyme with a pI of 6.4. Kinetic parameters of purified G3PDH from prairie dog liver and muscle were characterized at 22 and 5 °C and compared with rabbit muscle G3PDH. Substrate affinities for hi ... | 2011 | 22180227 |
| a plague epizootic in the black-tailed prairie dog (cynomys ludovicianus). | plague is the primary cause for the rangewide decline in prairie dog (cynomys spp.) distribution and abundance, yet our knowledge of plague dynamics in prairie dog populations is limited. our understanding of the effects of plague on the most widespread species, the black-tailed prairie dog (c. ludovicianus), is particularly weak. during a study on the population biology of black-tailed prairie dogs in wyoming, usa, plague was detected in a colony under intensive monitoring, providing a unique o ... | 2006 | 16699150 |
| diagnostic peritoneal lavage for identification of blastomycosis in a dog with peritoneal involvement. | a 6-year-old castrated male dalmatian was evaluated because of hematemesis. the dog had lived its entire life in south dakota and wyoming and had never traveled outside of these states. results of laboratory testing were compatible with iatrogenic acute renal failure and gastrointestinal tract ulceration secondary to previous nonsteroidal anti-inflammatory drug and corticosteroid administration. differential diagnoses for clinical signs and laboratory abnormalities that existed prior to these tr ... | 2003 | 14664450 |
