OBJECTIVE To characterize the risk of interactions that may lead to the transmission of Mycobacterium bovis between cattle and white-tailed deer (Odocoileus virginianus) on farms in northern Minnesota. SAMPLE 53 cattle farms in northwestern Minnesota adjacent to an area where bovine tuberculosis-infected cattle and deer were detected. PROCEDURES A semiquantitative deer-cattle interaction as...

Observations of extended estrus seasons in female white-tailed deer (Odocoileus virginianus) vaccinated with porcine zona pellucida (PZP) immunocontraceptives have led to speculation that management use of PZP would, perversely, increase the rate of deer–vehicle collisions. To test this hypothesis, we studied PZP-treated female deer at the National Institute of Standards and Technology, Gaither...

Deer are considered important intermediate hosts for the coccidian parasites, Toxoplasma gondii and Neospora caninum. Antibodies to N. caninum and T. gondii were determined in sera of 42 mule deer (Odocoileus hemionus hemionus) and 43 black-tailed deer (Odocoileus hemionus columbianus) from Washington state, USA, using direct agglutination test with specific antigens. A titer of 1:25 was consid...

Assemblages of introduced taxa provide an opportunity to understand how abiotic and biotic factors shape habitat use by coexisting species. We tested hypotheses about habitat selection by two deer species recently introduced to New Zealand's temperate rainforests. We hypothesised that, due to different thermoregulatory abilities, rusa deer (Cervus timorensis; a tropical species) would prefer wa...

In this investigation, the nature and distribution of histologic lesions and immunohistochemical staining (IHC) of a proteinase-resistant prion protein were compared in free-ranging mule deer (Odocoileus hemionus) dying of a naturally occurring spongiform encephalopathy (SE) and captive mule deer dying of chronic wasting disease (CWD). Sixteen free-ranging deer with SE, 12 free-ranging deer wit...

Abrasion of dental crown and the shape of denture occlusal surface are significant indicators in age determination of domestic mammals. The factors that significantly influence age determination of Eneolithic deer game in conditions of an open wildlife habitat are climatic changes that influenced their survival, as well as specific features of teeth morphological structure. In this paper the ag...

Enterocytozoon bieneusi is the most frequently diagnosed microsporidian species in humans and is also found in a wide range of animals. It is considered to be an important but neglected zoonotic pathogen. With the development of deer bred in captivity, the number of deer has been increasing in recent years in China and there are more people involved in this work. The aims of this study were to ...

High white-tailed deer (Odocoileus virginianus) densities in urban areas typically result in human–wildlife conflicts (e.g., deer– vehicle collisions, transmission of disease to humans, and vegetation damage). Controlling deer densities via fertility control generally is more acceptable than lethal removal in many urban areas and can reduce conflicts by stabilizing deer numbers. Contraceptive v...

We monitored the abundance of Ixodes scapularis Say (Acari: Ixodidae) and the Lyme disease incidence rate after the incremental removal of white-tailed deer, Odocoileus virginianus Zimmermann, within a suburban residential area to determine whether there was a measurable decrease in the abundance of ticks due to deer removal and whether the reduction in ticks resulted in a reduction in the inci...

Wild deer have an important role in the epidemiology of bovine tuberculosis (bTB). The aims of this study were (1) to compare the pattern of lesions present in wild red (Cervus elaphus) and fallow (Dama dama) deer that were naturally infected with Mycobacterium bovis, and (2) to use this information to develop a sampling strategy for the isolation of M. bovis from the lymphoid tissues of the he...
