“…The first recorded case of bovine tuberculosis (bTB) in a feral deer in the British Isles was in a fallow deer with generalised bTB in Co Wicklow, Ireland in 1974 (Wilson and Harrington, 1976). Infection in fallow deer has been recorded in Denmark (Jorgensen et al, 1988), Ireland (Wilson and Harrington, 1976;O'Reilly and Daborn, 1995), Spain Romero et al, 2008) and in GB (Delahay et al, , 2007bPaterson, 2008;Symmons, 2008).…”

Gross and Microscopic Lesions of Naturally Occurring Tuberculosis in a Captive Herd of Wapiti (Cervus Elaphus Nelsoni) in Colorado

et al. 1992

Abstract. A Mycobacterium bovis-infected herd of captive wapiti (Cervus elaphus nelsoni) in Colorado wasdepopulated after lesions of bovine tuberculosis were confirmed in 8 of 10 tuberculin skin test reactors. Of the 43 animals > 1 year of age, 26 had gross lesions suggestive of tuberculosis, 24 had microscopic lesions of tuberculosis, and 23 had acid-fast bacilli associated with the lesions. Lungs and retropharyngeal lymph nodes were the most frequently affected sites. Most lesions grossly and microscopically resembled tuberculosis in cattle; however, some lesions resembled abscesses or ovine caseous lymphadenitis lesions. Special stains and immunohistochemical techniques labeled few to numerous mycobacteria associated with the lesions.Until recently, bovine tuberculosis was considered an unusual and sporadic disease in cervids. Reported cases involved captive and wild cervids and were often attributed to contact with infected cattle or bison. 14,16,24 With recent development and expansion of game farming, the prevalence, economic impact, and public health significance of tuberculosis in captive cervids have greatly increased. 6,9,32 In New Zealand, tuberculosis was diagnosed in wild red deer (Cervus elaphus elaphus) in 1970 2 and in farmed deer in 1978. 17 It is now considered the most important bacterial disease in New Zealand's farmed deer population. 6,13,32 Bovine tuberculosis has also been diagnosed in several species of free-living and captive cervids from other countries 1,8,11,15,19,20,25,[29][30][31]33,35,36,43 In North America, reports of tuberculosis in cervids have been limited to sporadic cases in wild and captive white-tailed deer (Odocoileus virginianus) 26 This report provides more detailed descriptions of all gross and microscopic lesions of bovine tuberculosis observed in this herd. Materials and methodsAll animals were killed by gunshot. Necropsies were done, gross lesions recorded and photographed, and tissue specimens collected.26 Samples of grossly observed lesions and/ or parotid, mandibular, retropharyngeal, mediastinal, bronchial, hepatic, and mesenteric lymph nodes that were routinely bisected were placed in 10% neutral buffered formalin and saturated sodium borate transport solution for mycobacterial culture. Specimens were transported within 4 days to the National Veterinary Services Laboratories, Ames, Iowa, for histopathologic examination and mycobacterial culture.Formalin-fixed tissues were routinely processed using paraffin embedding, and 5-µm sections were stained with hematoxylin and eosin (HE). Significantly mineralized tissues were decalcified and routinely processed. Additional sections from tissues with lesions suggestive of tuberculosis were stained by a new fuchsin-methylene blue procedure (NF) 18 and acridine orange-auramine O (AOA0) 27 and were examined for the presence of acid-fast bacilli and AOAO fluorescent bacilli. Some sections were also stained with Giemsa and Gram's stains.Selected specimens were stained by a labeled streptavidinbiotin immunohistochemical t...

“…The intradermal skin test Tuberculosis caused by M. bovis has been diagnosed histologically at necropsy in wild deer in the United States (Towar et al 1965) and Europe (Wilson & Harrington 1976) and was first diagnosed in a herd of domesticated New Zealand deer in 1979 (Beatson et al 1984). Attempts to use herd-based diagnostic intradermal tests for deer showed that the conventional bovine intradermal skin test protocol needed to be modified.…”
