a serosurvey of diseases of free-ranging gray wolves (canis lupus) in minnesota.we tested serum samples from 387 free-ranging wolves ( canis lupus ) from 2007 to 2013 for exposure to eight canid pathogens to establish baseline data on disease prevalence and spatial distribution in minnesota's wolf population. we found high exposure to canine adenoviruses 1 and 2 (88% adults, 45% pups), canine parvovirus (82% adults, 24% pups), and lyme disease (76% adults, 39% pups). sixty-six percent of adults and 36% of pups exhibited exposure to the protozoan parasite neospora caninum . ...201728192048

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 ...200818957638
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 ...19862851572
detection of parvoviruses in wolf feces by electron 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.19882832624
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 ...19938387611
