In September 2002, chronic wasting disease (CWD), a prion disorder of captive and wild cervids, was diagnosed in a white-tailed deer (Odocoileus virginianus) from a captive farm in Wisconsin. The facility was subsequently quarantined, and in January 2006 the remaining 76 deer were depopulated. Sixty animals (79%) were found to be positive by immunohistochemical staining for the abnormal prion p...

Concern about emerging diseases has risen in recent years, and multihost situations have become increasingly relevant for wildlife management and conservation. We present data on Asturias, northern Spain, where 80 mangy red deer (Cervus elaphus) have been found since the beginning of the epizootic in chamois (Rupicapra pyrenaica parva) in 1993. We combine field and necropsy data with the result...

The study was carried out in zoo animals at Islamabad Zoo, Pakistan to know the prevalence of bovinetuberculosis. An overall prevalence of 3.3% was recorded in zoo animals with 3.6% in Bovidae, 3.2% inCervidae and 0% in Equidae families. The positive animals included spotted deer (1/3; 95% CI = 0.84,90.57), Chinkara gazella (1/5; 95% CI = 0.51, 71.64) and Blackbuck gazelle (1/30; 95% CI = 0.08,...

This study was conducted at the XINGLONGSHAN Musk Deer Farm of China from July to September 2008. Results showed that captive male musk deer exhibit aggressive dominance behavior, by which a stable social ranking is established. Generally, there were three types of aggression in agonistic interactions among males: attacking, displacing and threatening. Threatening was more frequently observed t...

Deer are acknowledged as hosts of Mycobacterium bovis, the causative agent of bovine tuberculosis (bTB), and determining the prevalence of infection in deer species is one of the key steps in understanding the epidemiological role played by cervids in the transmission and maintenance of bTB in the United Kingdom. This study evaluated a rapid lateral-flow test for the detection of bTB in samples...

Strategies for managing chronic wasting disease (CWD) in urban mule deer (Odocoileus hemionus) populations are needed in Colorado. We captured, tonsil-biopsied, marked, and tested adult mule deer (n=181) to evaluate the feasibility of conducting an urban "test-and-cull" program in Estes Park, Colorado. During December 2002 and April-May 2003, we successfully tested 51 (57O/%) of the estimated 8...

Community assembly entails a filtering process, where species found in a local community are those that can pass through environmental (abiotic) and biotic filters and successfully compete. Previous research has demonstrated the ability of white-tailed deer (Odocoileus virginianus) to reduce species diversity and favour browse-tolerant plant communities. In this study, we expand on our previous...

The aim of this study is to describe differences in the ontogenesis of the omasum in sheep (domestic ruminant) and deer (wild ruminant). A total of 50 embryos and fetuses of Merino sheep and 50 Iberian deer were used, from the first stages of prenatal life until birth. For the study, the animals were divided into five experimental groups according to the most relevant histological characteristi...

Nymphal Ixodes scapularis Say deer ticks were collected at 22 parks or other natural areas on Long Island, New York, to examine the relationship between tick populations and geographic position, size of area, presence of white-tailed deer, Odocoileus virginianus (Zimmerman), and numbers of human Lyme disease cases in adjacent communities. Nymphal ticks were 93% less abundant when deer were abse...

The New Zealand deer industry is growing rapidly and the development of sustainable management practices for deer farming is becoming increasingly important. The main environmental issues facing the deer industry are the effects on soil and water quality, exacerba ted by the behaviour responses of deer to confinement (in particular fence pacing and wallowing). In addition, the projected increas...
