5 Year Strategic Plan for CHeRI (pdf) - In order to guide our research and extension priorities for the next 5 years of CHeRI, we have established a Strategic Plan to provide a roadmap to our mission.

Trueperella (Arcanobacterium pyogenes) in Farmed White-Tailed Deer (pdf) - Trueperella is a bacterium that can cause lesions in multiple areas of the body including the lungs, mouth, skin, and liver. It is a common cause of abscesses and pneumonia in deer. It also causes lesions on the face, ears, neck, lungs, and lymph nodes. It is one of the types of bacteria that is known to contribute to the disease lumpy jaw. In young fawns, it is a common cause of mortality (Ribeiro et al. 2015).

Common Disease of Captive Fawns in Florida (pdf) - Fawning season is a stressful time for deer farmers. From birth to weaning, white-tailed deer fawns have a high mortality rate. There are multiple reasons for the high death rate, but most are associated with the animalís developing immune system and exposure to a variety of bacteria and viruses.

Facts about Wildlife Diseases: Hemorrhagic Fever in White-Tailed Deer (pdf) - The viruses that cause hemorrhagic disease (HD) in deer do not cause illness in people, but they are a growing problem. HD is the most important viral disease of white-tailed deer in the United States. Large outbreaks have occurred in the northern Midwest and western United States. In Florida outbreaks are fewer and less severe in populations of wild white-tailed deer than are outbreaks among wild deer in other areas of the United States, but farm-raised deer in the state are proving vulnerable to epizootic hemorrhagic disease virus: one of the viruses that cause HD. This 6-page fact sheet written by Katherine A. Sayler, Charlotte Dow, and Samantha M. Wisely and published by the Department of Wildlife Ecology and Conservation describes best management techniques for outbreaks of HD in farm-raised deer. It includes strategies for best supportive care for sick animals, diagnostics, and integrated pest management to control biting midges that spread the viruses that cause HD, because the best way to manage HD is to prevent it.

Primary Screwworm Cochliomyia hominivorax (Coquerel) (Insecta: Diptera: Calliphoridae) (pdf) - Screwworms are endemic to the Western Hemisphere and pose a serious threat to livestock, wildlife, pets, and humans (Williams et al. 1985; Mullen and Durden 2009; CABI 2016). The primary screwworm,† Cochliomyia hominivorax (Coquerel) (Figure 1), also known as the New World screwworm, occurred in several areas of the southern United States before eradication efforts began in the 1950s (Krafsur et al. 1987). Although considered eradicated throughout most of North America, active infestations still occur in Jamaica, Cuba, and across South America. Typical insecticide suppression of the primary screwworm is not as effective as with other insect pests. Along with other control measures, the release of sterile insects, known as the sterile insect technique or SIT, was successfully used in eradication efforts in North America (Vyrsen et al. 2007). In October of 2016, the USDA-APHIS (United States Department of Agriculture-Animal and Plant Health Inspection Service) confirmed the presence of primary screwworm in Key deer (Odocoileus virginianus clavium) on Big Pine Key in Florida. Key deer are an endangered species that have been found only on the Florida Keys, and several have died or been euthanized due to the 2016 screwworm infestations (FDACS 2016). A second screwworm species, the secondary screwworm, Cochliomyia macellaria (Fabricius) also is found in Florida; however, this species only infests dead animals or animals already harboring primary screwworm infestations (Byrd 1998).
