The black skimmer () is a state-threatened, colonially nesting seabird in Florida, USA. Conservation threats include habitat alteration, human disturbances, severe weather, and predation. During nest monitoring (May-September, 2020-2022), black skimmer juveniles at colonies on Fort Myers Beach and Marco Island, Florida, had polyarthritis and died or were euthanized due to severe illness.

- The Wild Turkey, a significant game bird in North America, has faced health risks due to population declines and diseases like histomonosis caused by the parasite Histomonas meleagridis.
- A study from 2002 to 2023 found that out of 857 turkeys examined, 4% had trichomonad disease, with a variety of trichomonads found, indicating a more complex disease landscape than previously understood.
- Coinfections with other diseases and pathogens were common among affected turkeys, underscoring the necessity for advanced molecular diagnostics to accurately identify the causes of illness.
Rabbit hemorrhagic disease virus 2 (RHDV2) has spread across the United States infecting and causing death in domestic and wild rabbits. Immunohistochemistry (IHC) would be a useful tool for the detection of RHDV2 antigen in tissues as it is inexpensive and readily achievable in most diagnostic laboratories. However, there is no readily available antibody for this purpose.

- Trichomonas gypaetinii was found in 88% of Bald Eagles sampled, indicating it is common among this species in the USA.
- No Golden Eagles tested positive for the parasite, suggesting a species-specific prevalence.
- Despite the high rate of infection in Bald Eagles, none showed any related health issues or lesions.
Interest in causes of mortality of free-ranging, native North American lagomorphs has grown with the emergence of rabbit hemorrhagic disease virus 2 (RHDV2). Over the years 2013-2022, the Southeastern Cooperative Wildlife Disease Study received 119 spp. case submissions from the central and eastern United States, comprising 147 rabbits.

Animals: 6 juvenile female rabbits (n = 5 treatment and 1 control).
Methods: An ultrafiltration probe and CSBs were placed SC in 6 rabbits (n = 5 for FF CSBs and 1 for control CSBs).
Article Synopsis
- Listeria monocytogenes is a bacterium that can infect various species, including humans and wildlife, and may spread more easily due to overlapping habitats.
- A study analyzed diagnostic data from 1991 to 2020, finding that gray foxes and wild turkeys showed significant lesions from listeriosis and other comorbidities, like canine distemper virus.
- The research confirmed listeriosis as a serious health threat in these wildlife species, which often experienced additional infections that could weaken their immune systems.
The white-tailed deer (Odocoileus virginianus) is a popular game species in North America and often lives in close proximity to humans and domestic animals. Deer with neurologic signs are of high interest to the general public and wildlife managers because of disease and safety concerns. Our aim was to describe diagnostic findings from free-ranging white-tailed deer diagnosed with rabies from across the eastern US from 2000 to 2021, with emphasis on gross lesions in the skin and soft tissue overlying the skull.

This virus is responsible for population declines of some Passeriformes. We describe a WNV-associated mortality event in American White Ibis (Eudocimus albus) nestlings.
