ABSTRACTThe control of multihost pathogens, such asCoxiella burnetii, should rely on accurate information about the roles played by the main hosts. We aimed to determine the involvement of the red deer (Cervus elaphus) in the ecology ofC. burnetii. We predicted that red deer populations from broad geographic areas within a European context would be exposed toC. burnetii, and therefore, we hypothesized that a series of factors would modulate the exposure of red deer toC. burnetii. To test this hypothesis, we designed a retrospective survey of 47 Iberian red deer populations from which 1,751 serum samples and 489 spleen samples were collected. Sera were analyzed by enzyme-linked immunosorbent assays (ELISA) in order to estimate exposure toC. burnetii, and spleen samples were analyzed by PCR in order to estimate the prevalence of systemic infections. Thereafter, we gathered 23 variables—within environmental, host, and management factors—potentially modulating the risk of exposure of deer toC. burnetii, and we performed multivariate statistical analyses to identify the main risk factors. Twenty-three populations were seropositive (48.9%), andC. burnetiiDNA in the spleen was detected in 50% of the populations analyzed. The statistical analyses reflect the complexity ofC. burnetiiecology and suggest that although red deer may maintain the circulation ofC. burnetiiwithout third species, the most frequent scenario probably includes other wild and domestic host species. These findings, taken together with previous evidence ofC. burnetiishedding by naturally infected red deer, point at this wild ungulate as a true reservoir forC. burnetiiand an important node in the life cycle ofC. burnetii, at least in the Iberian Peninsula.

372 sera of cervids from the Czech Republic were examined for antibodies to the bovine viral diarrhea virus (BVDV) and border disease virus (BDV) by competitive-inhibition enzyme-linked immunosorbent assay (ELISA), and for the presence of the BVDV by AgELISA. Antibodies to BVDV/BDV were found in 0.6% (two positive/305 tested) red deer (<I>Cervus elaphus</I>). BVDV/BDV antibodies were not found in four sika deer (<I>Cervus Nippon</I>) and 63 fallow deer (<I>Dama dama</I>). All serum samples were BVDV antigen negative. Our results confirmed that red deer in the Czech Republic are only rarely infected with Pestiviruses. This was the first survey of pestiviruses in farmed and wild cervids in the Czech Republic.

Surveillance forMycobacterium bovisin free-ranging elk (Cervus elaphus) and white-tailed deer (Odocoileus virginianus) from south-western Manitoba was carried out from 1997 to 2010 to describe the lesions, epidemiology, and geographic distribution of disease. Tissues were cultured from animals killed by hunters, culled for management, blood-tested, or found opportunistically. Period prevalence in elk was approximately six times higher than deer, suggesting a significant reservoir role for elk, but that infected deer may also be involved. Prevalence was consistently higher in elk compared to deer in a small core area and prevalence declines since 2003 are likely due to a combination of management factors instituted during that time. Older age classes and animals sampled from the core area were at significantly higher risk of being culture positive. Positive elk and deer were more likely to be found through blood testing, opportunistic surveillance, and culling compared to hunting. No non-lesioned, culture-positive elk were detected in this study compared to previous studies in red deer.

ABSTRACTBovine tuberculosis (TB) in cervids remains a significant problem affecting farmed herds and wild populations. Traditional skin testing has serious limitations in certain species, whereas emerging serological assays showed promising diagnostic performance. The recently developed immunochromatographic dual-path platform (DPP) VetTB assay has two antigen bands, T1 (MPB83 protein) and T2 (CFP10/ESAT-6 fusion protein), for antibody detection. We evaluated the diagnostic accuracy of this test by using serum samples collected from groups of white-tailed deer experimentally inoculated withMycobacterium bovis,M. aviumsubsp.paratuberculosis, orM. bovisBCG Pasteur. In addition, we used serum samples from farmed white-tailed deer in herds with no history of TB, as well as from free-ranging white-tailed deer culled during field surveillance studies performed in Michigan known to have bovine TB in the wild deer population. The DPP VetTB assay detected antibody responses in 58.1% of experimentally infected animals within 8 to 16 weeks postinoculation and in 71.9% of naturally infected deer, resulting in an estimated test sensitivity of 65.1% and a specificity of 97.8%. The higher seroreactivity found in deer with naturally acquiredM. bovisinfection was associated with an increased frequency of antibody responses to the ESAT-6 and CFP10 proteins, resulting in a greater contribution of these antigens, in addition to MPB83, to the detection of seropositive animals, compared with experimentalM. bovisinfection. Deer experimentally inoculated with eitherM. aviumsubsp.paratuberculosisorM. bovisBCG Pasteur did not produce cross-reactive antibodies that could be detected by the DPP VetTB assay. The present findings demonstrate the relatively high diagnostic accuracy of the DPP VetTB test for white-tailed deer, especially in the detection of naturally infected animals.
