Butorphanol-azaperone-medetomidine (BAM) is commonly used for white-tailed deer (Odocoileus virginianus) immobilization in captive and free-ranging populations. It is a federally regulated controlled substance requiring stringent regulatory compliance, complicating field application. A prescription-only drug combination, nalbuphine-medetomidine-azaperone® (NalMed-A) provides a less-regulated alternative for use by wildlife professionals.

Neither target revealed separation between morphotypes, confirming they are the same species and providing new data on Ostertagia morphotypes.

- Researchers in Key Largo, Florida, studied black rats to explore the impact of diseases or parasites on their declining population, discovering that 94% of the sampled rats were infected with Sarcocystis sp.
- The identified strain of Sarcocystis was closely related to a newly described parasite, Sarcocystis kani, which primarily uses Asian snakes as hosts and affects rodents.
- The increase of invasive Burmese pythons in the area likely contributes to the spread of this parasite and adds predation pressure on local wildlife, highlighting the need for ongoing monitoring and studies on parasites affecting both snakes and rodents in south Florida.
We estimated the probabilities of detecting one or more chronic wasting disease (CWD) cases (Pdet) in free-ranging cervids in the continental US during 1997 - 2001. Based on sample sizes reported by respective state authorities at the time and a target for detectable apparent prevalence (i.e.

Globally, seven known EHDV serotypes circulate among ruminant hosts and Culicoides species vectors. A variety of domestic and wild ruminant species are susceptible to EHDV infection, but infection outcome is highly variable between species, as well as between individuals of the same species.
