sheep-associated malignant catarrhal fever in a petting zoo.in a privately owned petting zoo in arizona, 17 deer from five different species, white-tailed deer (odocoileus virginianus), reeve's muntjac (muntiacus reevesi), mule deer (odocoileus hemionus), reindeer (rangifer tarandus), and axis deer (axis axis), died of suspected malignant catarrhal fever (mcf) over a period from late 1992 to early 1995. a pcr assay specific for ovine herpesvirus 2, the putative causative agent of sheep-associated mcf, and a competitive-inhibition enzyme-linked immunosorb ...199910572865
hemorrhagic disease in deer in arizona.two mule deer (odocoileus hemionus) and one white-tailed deer (odocoileus virginianus) in arizona (usa) were submitted for necropsy. gross and microscopic lesions compatible with hemorrhagic disease (hd) were observed in all three deer. epizootic hemorrhagic disease virus type 2 (ehdv-2) was isolated from two of the deer. to our knowledge, this is the first documentation of hd in deer in arizona. two of the mortalities were attributed to ehdv-2 infection.200211838211
rabies surveillance in the united states during 2001.during 2001, 49 states and puerto rico reported 7,437 cases of rabies in nonhuman animals and 1 case in a human being to the centers for disease control and prevention, an increase of < 1% from 7,364 cases in nonhuman animals and 5 human cases reported in 2000. more than 93% (6,939 cases) were in wild animals, whereas 6.7% (497 cases) were in domestic species (compared with 93.0% in wild animals and 6.9% in domestic species in 2000). the number of cases reported in 2001 increased among bats, cat ...200212494966
epizootiology of hemorrhagic disease in mule deer in central arizona.we report two male mule deer (odocoileus hemionus) mortalities that occurred near prescott, arizona (usa) in september 2001. necropsy lesions were compatible with those described for hemorrhagic disease (hd). bluetongue (btv) and epizootic hemorrhagic disease (ehdv) viral rna were identified in tissues from one deer and ehdv viral rna was identified in the other via reverse transcription-polymerase chain reaction (rt-pcr). virus isolation attempts were unsuccessful in both cases. to determine ge ...200415137498
determining prevalence of bluetongue and epizootic hemorrhagic disease viruses in mule deer in arizona (usa) using whole blood dried on paper strips compared to serum analyses.we investigated the feasibility of using whole blood dried on paper strips as a means to collect antibody prevalence data for the epizootic hemorrhagic disease viruses (ehdv) and bluetongue viruses (btv) from hunter-harvested male mule deer (odocoileus hemionus) in october 2002 from arizona, usa. we compared antibody prevalence estimates in mule deer from paired paper strip and serum samples. prevalence data obtained from elution of dried blood on paper strips proved to be consistent with result ...200616699159
blood and urinary profiles of free-ranging desert mule deer in arizona.as a corollary to a more comprehensive study on their ecology, we documented blood and urinary profiles for 10 free-ranging desert mule deer (odocoileus hemionus crooki) (five males, five females) captured by net-gun shot from a helicopter during february 1988 in saguaro national monument, arizona. pursuit with the helicopter for netting deer ranged from 3 to 15 min. blood profiles included seven hematological characteristics and 12 serum chemistries, electrolytes, hormones and enzymes. urine sa ...19902304204
evidence of tick-borne organisms in mule deer (odocoileus hemionus) from the western united states.free-ranging mule deer (md; odocoileus hemionus) from arizona and california were tested for evidence of infection with several tick-borne pathogens, including species of ehrlichia, anaplasma, babesia, and borrelia. of 125 mule deer tested from arizona, 29 (23%) and 11 (9%) had antibodies reactive to e. chaffeensis and a. phagocytophilum by indirect immunofluorescent antibody testing, respectively; none of the six md tested from california were seropositive. using a commercial competitive elisa ...200516417431
an outbreak of type c botulism in 12 horses and a mule.a usda early response team investigated deaths of several horses and a mule in northern arizona at the request of local animal health officials. thirteen animals (12 horses and 1 mule) housed at 5 facilities in a 7.4 square mile area died between august 1998 and january 1999. clinical signs consisted of muscular weakness that rapidly progressed to lateral recumbency. ten animals had paresis of the tongue, throat, or lips. affected animals appeared alert and were interested in eating and drinking ...200010935041
belowground fungal associations and water interact to influence the compensatory response of ipomopsis aggregata.although the concept that some plants benefit from being eaten is counterintuitive, there is now considerable evidence demonstrating enhanced fitness following herbivory. it has been assumed that plants growing in high resource conditions are the ones best able to compensate for herbivory. however, just the opposite has been found for dicotyledonous plants exhibiting patterns of overcompensation, with most occurring in resource-poor conditions. long-term studies of the monocarpic biennial, scarl ...201626497124
the rise and fall of psoroptic scabies in bighorn sheep in the san andres mountains, new mexico.between 1978 and 1997, a combination of psoroptic scabies (psoroptes spp.), mountain lion (puma concolor) predation, and periodic drought reduced a population of native desert bighorn sheep (ovis canadensis) in the san andres mountains (sam), new mexico, from >200 individuals to a single ewe. in 1999, this ewe was captured, ensured to be psoroptes-free, and released back into the sam. eleven radio-collared rams were translocated from the red rock wildlife area (rrwa) in new mexico into the sam r ...200516244062
