serologic survey for selected infectious disease agents in swift and kit foxes from the western united states.a serologic survey of swift fox (vulpes velox) and kit fox (v. macrotis) from the western usa was conducted for 12 infectious diseases. samples from swift fox were collected between 1987 and 1992 from colorado (n = 44), kansas (n = 10), and wyoming (n = 9). samples from kit fox were collected in california (n = 86), new mexico (n = 18), utah (n = 9), and arizona (n = 6). overall antibody prevalence rates were 33 of 110 (30%) for canine parvovirus (cpv), 9 of 72 (13%) for canine distemper virus ( ...200011085448
demographic characteristics and infectious diseases of a population of american black bears in humboldt county, california.american black bears (ursus americanus) are common, widely distributed, and broad-ranging omnivorous mammals in northern california forests. bears may be susceptible to pathogens infecting both domestic animals and humans. monitoring bear populations, particularly in changing ecosystems, is important to understanding ecological features that could affect bear population health and influence the likelihood that bears may cause adverse impacts on humans. in all, 321 bears were captured between may ...201525700042
zoonotic vector-borne bacterial pathogens in california mountain lions (puma concolor), 1987-2010.sera collected from 442 mountain lions in 48 california counties between the years of 1987 and 2010 were tested using immunofluorescence assays and agglutination tests for the presence of antibodies reactive to yersinia pestis, francisella tularensis, bartonella henselae, borrelia burgdorferi, and anaplasma phagocytophilum antigens. data were analyzed for spatial and temporal trends in seropositivity. seroprevalences for b. burgdorferi (19.9%) and b. henselae (37.1%) were relatively high, with t ...201222925024
pathogen and rodenticide exposure in american badgers (taxidea taxus) in california.urban and agricultural land use may increase the risk of disease transmission among wildlife, domestic animals, and humans as we share ever-shrinking and fragmented habitat. american badgers (taxidae taxus), a species of special concern in california, usa, live in proximity to urban development and often share habitat with livestock and small peridomestic mammals. as such, they may be susceptible to pathogens commonly transmitted at this interface and to anticoagulant rodenticides used to contro ...201222493124
serological survey for selected diseases in the endangered san joaquin kit fox (vulpes macrotis mutica).blood from endangered san joaquin kit foxes (vulpes macrotis mutica) inhabiting the elk hills naval petroleum reserve, kern county, and the elkhorn plain, san luis obispo county, california, was collected in 1981, 1982 and 1984 and sera were tested for antibodies against 10 selected pathogens. proportions of kit fox sera containing antibodies against pathogens were: canine parvovirus, 100% in 1981-1982 and 67% in 1984; infectious canine hepatitis virus, 6% in 1981-1982 and 21% in 1984; canine di ...19882836636
a serologic survey of mule deer and elk in utah.sera from mule deer (odocoileus hemionus) and elk (cervus canadensis) in central and northern utah were tested for the prevalence of antibodies to 11 diseases communicable to man or domestic livestock. antibodies to francisella tularensis (at 1:20) were found in 47 of 88 (53.4%) elk and 1 of 89 (1.1%) deer. a screening slide agglutination test for titers to brucella (at 1:20) showed two reactors in elk but none in deer sera. no positive antibody titers were obtained in tests for anaplasmosis, co ...1978105153
ectoparasite diversity and exposure to vector-borne disease agents in wild rodents in central coastal california.a survey of wild rodents was performed in the morro bay area of central coastal california to determine serological and polymerase chain reaction (pcr) prevalence of anaplasma phagocytophilum dumler, barbet, bekker, dasch, palmer, ray, rikihisa, and rurangirwa, borrelia burgdorferi johnson, schmidt, hyde, steigerwalt, and brenner, francisella tularensis mccoy, and yersinia pestis yersin; to describe the ectoparasitic fauna on important vector-borne disease hosts; and to determine whether pathoge ...200717427705
disease surveillance of california ground squirrels ( spermophilus beecheyi ) in a drive-through zoo in oregon, usa.rodents and other small wild mammals are often considered to be pests and vectors for disease in zoos that house small populations of valuable threatened and endangered animals. in 2005, three nonhuman primates at a drive-through zoo in oregon, us, acquired tularemia from an unknown source. due to an abundance of california ground squirrels ( spermophilus beecheyi ) on zoo grounds, we instituted serosurveillance of this species from july through september 2008 to determine the prevalence of anti ...201728418764
a molecular survey for francisella tularensis and rickettsia spp. in haemaphysalis leporispalustris (acari: ixodidae) in northern california.francisella tularensis and rickettsia spp. have been cultured from haemaphysalis leporispalustris packard, but their prevalence in this tick has not been determined using modern molecular methods. we collected h. leporispalustris by flagging vegetation and leaf litter and from lagomorphs (lepus californicus gray and sylvilagus bachmani (waterhouse)) in northern california. francisella tularensis dna was not detected in any of 1,030 ticks tested by polymerase chain reaction (pcr), whereas 0.4% of ...201628031350
