Nine species of ectoparasites (4 Acari, 2 Mallophaga, 1 Anoplura, 1 Diptera, and 1 Siphonaptera) were recovered from 126 white-tailed deer collected in northern, central, and southern Mississippi. Intensity and prevalence of adults of Ixodes scapularis and larvae, nymphs, and adults of Amblyomma americanum varied significantly over collection periods, but not between host sexes. Lipoptena mazamae occurred on deer from only one study area. Although individual deer were heavily parasitized by Tricholipeurus parallelus and T. lipeuroides, their prevalence was limited. Hoplopsyllus sp., Solenopotes sp., Amblyomma maculatum, and Dermacentor albipictus had prevalences of less than 10% and were not tested for area, host sex, and seasonal effects. The potential pathogenicity of these ectoparasite species are related to white-tailed deer in Mississippi.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been detected in multiple animal species, including white-tailed deer (WTD), raising concerns about zoonotic transmission, particularly in environments with frequent human interactions. To understand how human exposure influences SARS-CoV-2 infection in WTD, we compared infection and exposure prevalence between farmed and free-ranging deer populations in Florida. We also examined the timing and viral variants in WTD relative to those in Florida's human population.

Disease monitoring informs the opportunities for intervention by natural resource agencies tasked with managing chronic wasting disease (CWD) in wild cervids. However, allocating funds toward testing can reduce those available for education, outreach, and disease reduction. Implementation of more efficient testing strategies can help meet both an expanding need by resource managers and a burgeoning demand from the hunting public in North America.

The pressure on ecosystems resulting from outdoor recreational activities is increasing globally. Protected areas offer to large mammals refugia free of hunting with greater access to food resources, but the presence of humans for recreation in these areas may induce changes in behaviour, activity pattern, and habitat use. We used camera traps to model the spatial distribution and temporal activity of the white-tailed deer (Odocoileus virginianus) in a nature reserve located close to Montreal, the second largest metropole in Canada.

Objective: Extracting DNA is essential in wildlife genetic studies, and numerous methods are available. However, the process is costly and time-consuming for non-model organisms, including most wildlife species. Therefore, we optimized a cost-efficient protocol to extract DNA from the muscle tissue of White-tailed Deer using the DNAdvance kit (Beckman Coulter), a magnetic-bead-based approach.

Identifying cellular markers within archived formalin-fixed, paraffin-embedded (FFPE) tissues is critical for understanding tissue landscapes impacting animal health, but in situ detection methods are limited in veterinary species by a restricted toolbox of species-compatible immunoreagents. We identify antibodies with conserved in situ reactivity to IBA-1 (macrophages/dendritic cells), CD3ε (T cells), Pax5 (B cells), Ki-67 (cycling cells), and cytokeratin type I/II (epithelial cells) in FFPE tissues of pigs, cattle, and white-tailed deer. Multiplexed brightfield detection (IBA-1/CD3ε/Pax5) in lymph nodes of all three species demonstrated species-specific and species-conserved features of cellular architecture.
