| detection of parvoviruses in wolf feces by electron microscopy. | one hundred fifteen wolf (canis lupus) feces were collected between 1980 and 1984 from northeastern minnesota and were examined for canine parvovirus by negative contrast electron microscopy. of these, seven (6%) samples revealed the presence of parvovirus. some of these viruses were able to grow in cell cultures forming intranuclear inclusion bodies and giant cells. | 1988 | 2832624 |
| antibodies against canine parvovirus in wolves of minnesota: a serologic study from 1975 through 1985. | serum samples (n = 137) from 47 wild wolves (canis lupus; 21 pups and 26 adults) were evaluated from 1975 to 1985 for antibodies against canine parvovirus, using the hemagglutination inhibition (hi) test. in addition, several blood samples (n = 35) from 14 of these wolves (6 pups and 8 adults) were evaluated simultaneously for erythrocyte and leukocyte counts, and for hemoglobin and blood urea nitrogen concentrations. sixty-nine (50%) of the serum samples (35 wolves) had hi titers of greater tha ... | 1986 | 2851572 |
| prenatal and preweaning deaths caused by pseudorabies virus and porcine parvovirus in a swine herd. | sequential outbreaks of pseudorabies virus and porcine parvovirus infections were documented at a swine farm in southern minnesota. data for the prevalence of mummified fetuses born and the preweaning mortality were recorded over a 3-year-period. the farm was a farrow-to-finish facility, with breeding females housed in 4 groups according to their stage of pregnancy. the herd consisted of approximately 130 breeding females in december 1981, and expanded to 220 females during the 12 months of 1982 ... | 1985 | 2997093 |
| canine parvovirus infection in wolves (canis lupus) from minnesota. | | 1986 | 3005665 |
| survey of porcine parvovirus infection in swine fetuses and their dams at a minnesota abattoir. | reproductive tracts were recovered from 209 sow and 32 gilt carcasses at slaughter; animals had been pregnant not less than 27 days. of 241 litters examined, 28 (11.6%) contained one or more porcine parvovirus (ppv)-infected fetuses, as determined by immunofluorescent microscopy. the frequencies in sow and gilt litters were 12.0% and 9.4%, respectively. the ppv antigen was detected in 219 of 334 (65.6%) dead or mummified fetuses and in 12 of 2,172 (0.5%) live fetuses examined. the 18 litters whi ... | 1981 | 7258807 |
| canine parvovirus effect on wolf population change and pup survival. | canine parvovirus infected wild canids more than a decade ago, but no population effect has been documented. in wild minnesota wolves (canis lupus) over a 12-yr period, the annual percent population increase and proportion of pups each were inversely related to the percentage of wolves serologically positive to the disease. although these effects did not seem to retard this large extant population, similar relationships in more isolated wolf populations might hinder recovery of this endangered a ... | 1993 | 8387611 |
| the role of parvovirus b19 in the pathogenesis of giant cell arteritis: a preliminary evaluation. | to determine whether parvovirus b19 dna is more likely to be present in the temporal arteries of patients with giant cell arteritis (gca) than in the temporal arteries of control subjects. | 1999 | 10366119 |
| demographic effects of canine parvovirus on a free-ranging wolf population over 30 years. | we followed the course of canine parvovirus (cpv) antibody prevalence in a subpopulation of wolves (canis lupus) in northeastern minnesota from 1973, when antibodies were first detected, through 2004. annual early pup survival was reduced by 70%, and wolf population change was related to cpv antibody prevalence. in the greater minnesota population of 3,000 wolves, pup survival was reduced by 40-60%. this reduction limited the minnesota wolf population rate of increase to about 4% per year compar ... | 2008 | 18957638 |
