| coccidia of coyotes in eastern colorado. | eighty-two coyote fecal samples were collected from eastern colorado and examined for coccidia. sporocysts of sarcocystis were observed in 17 of the samples and oocysts of isospora ohioensis were observed in two samples. ten fecal samples contained eimerian coccidia thought to be pseudoparasites of the coyote acquired while ingesting heavily infected rabbits. | 1977 | 402487 |
| prevalence of antibodies against canine parvovirus and canine distemper virus in wild coyotes in southeastern colorado. | serum from 72 wild coyotes (canis latrans) in southeastern colorado (usa) was collected and analyzed for prevalence of antibody to canine parvovirus (cpv) and canine distemper virus (cdv) from 1985 to 1988. the prevalence of antibodies to cpv and cdv was 71% and 57%, respectively, for the 4 yr of the study. prevalence of antibody to cpv did not differ among years, between sexes, or with age. prevalence of antibody to cdv did not differ among years or between sexes, but was significantly higher i ... | 1991 | 1648628 |
| serologic survey for canine infectious diseases among sympatric swift foxes (vulpes velox) and coyotes (canis latrans) in southeastern colorado. | swift foxes (vulpes velox) and coyotes (canis latrans) are sympatric canids distributed throughout many regions of the great plains of north america. the prevalence of canid diseases among these two species where they occur sympatrically is presently unknown. from january 1997 to january 2001, we collected blood samples from 89 swift foxes and 122 coyotes on the us army piñon canyon maneuver site, las animas county, se colorado (usa). seroprevalence of antibodies against canine parvovirus (cpv) ... | 2004 | 15650093 |
| colorado animal-based plague surveillance systems: relationships between targeted animal species and prediction efficacy of areas at risk for humans. | human plague risks (yersinia pestis infection) are greatest when epizootics cause high mortality among this bacterium's natural rodent hosts. therefore, health departments in plague-endemic areas commonly establish animal-based surveillance programs to monitor y. pestis infection among plague hosts and vectors. the primary objectives of our study were to determine whether passive animal-based plague surveillance samples collected in colorado from 1991 to 2005 were sampled from high human plague ... | 2009 | 20836802 |
| bartonella rochalimae and b. vinsonii subsp. berkhoffii in wild carnivores from colorado, usa. | spleen samples from 292 wild carnivores from colorado, us were screened for bartonella infection. bartonella dna was detected in coyotes ( canis latrans ) (28%), striped skunks ( mephitis mephitis ) (23%), red foxes ( vulpes vulpes ) (27%), and raccoons ( procyon lotor ) (8%) but not in black bears ( ursus americanus ), gray foxes ( urocyon cinereoargenteus ), and mountain lions ( puma concolor ). two bartonella species, b. vinsonii subsp. berkhoffii and b. rochalimae, were identified. all 10 in ... | 2016 | 27529290 |
| serologic survey for cross-species pathogens in urban coyotes (canis latrans), colorado, usa. | abstract as coyotes (canis latrans) adapt to living in urban environments, the opportunity for cross-species transmission of pathogens may increase. we investigated the prevalence of antibodies to pathogens that are either zoonotic or affect multiple animal species in urban coyotes in the denver metropolitan area, colorado, usa, in 2012. we assayed for antibodies to canine parvovirus-2, canine distemper virus, rabies virus, toxoplasma gondii, yersinia pestis, and serotypes of leptospira interrog ... | 2014 | 25121408 |
| food webs and intraguild predation: community interactions of a native mesocarnivore. | trophic level interactions between predators create complex relationships such as intraguild predation. theoretical research has predicted two possible paths to stability in intraguild systems: intermediate predators either outcompete higher-order predators for shared resources or select habitat based on security. the effects of intraguild predation on intermediate mammalian predators such as swift foxes (vulpes velox) are not well understood. we examined the relationships between swift foxes an ... | 2007 | 17479752 |
| bait development for oral delivery of pharmaceuticals to raccoons (procyon lotor) and striped skunks (mephitis mephitis). | oral vaccination is one tool used to control wildlife diseases. a challenge to oral vaccination is identifying baits specific to target species. the us has been conducting oral vaccination against rabies since the 1990s. improvements in bait development will hasten disease elimination. in colorado, we examined a novel bait for oral vaccination and offered two different flavors, sweet and fish, to captive raccoons ( procyon lotor ) and striped skunks ( mephitis mephitis ) to assess consumption an ... | 2016 | 27505038 |
| anticoagulant rodenticide exposure and toxicosis in coyotes (canis latrans) in the denver metropolitan area. | anticoagulant rodenticides are widely used in urban areas to control rodent pests and are responsible for secondary poisoning in many nontarget wildlife species. we tested the livers of five coyotes (canis latrans) in the denver metropolitan area, colorado, us, for anticoagulant rodenticides. all five livers were positive for brodifacoum, with values ranging from 95 ppb to 320 ppb, and one liver was positive for bromadiolone, with a value of 885 ppb. both of these rodenticides are second-generat ... | 2015 | 25380355 |
