“…In whitetailed deer, elk (Cervus elaphus nelsoni), and red deer (Cervus elaphus) the preponderance of lesions occur in the medial retropharyngeal lymph nodes (Beatson, 1985;Whiting and Tessaro, 1994;O'Brien et al, 2001;Palmer et al, 2000). Similar to M. bovis infection of humans, but unlike tuberculosis in cattle, discharging sinus tracts have been associated with cranial lymph node lesions in red deer (Mackintosh and Griffin, 1994) and fallow deer (Dama dama) (Robinson et al, 1989), but not white-tailed deer. Tonsilar lesions are commonly seen in white-tailed deer with tuberculous lesions of the medial retropharyngeal lymph nodes (Palmer et al, 2002b).…”

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...

“…comm.). Fallow deer do contract Tb (Robinson et al 1989), and several of New Zealand's fallow herds occur in areas where the disease is regarded as endemic (permanently established in livestock and wildlife). The slow spread of fallow deer (Caughley 1963) and short dispersal distances (this study) suggest they are unlikely to spread the disease rapidly.…”

G. 1994. Home range size and its development for fallow deer in the Blue Mountains, New Zealand. Acta theriol. 39: 159-175.Fifty-nine fallow deer Dama dama dama (Linnaeus, 1758) fitted with radio collars were monitored in the Blue Mountains, Otago, New Zealand, between September 1985 and February 1988 to determine home range size and patterns of range development. Fallow deer occupy small annual ranges, averaging 66 ha for females and 189 ha for males (90% isopleths calculated by the Harmonic Mean method). For resident animals the respective values were 50 ha and 127 ha. Bimonthly seasonal range size varied with sex, age-class and season, with different seasonal patterns for males and females. Only one adult female dispersed, and most females occupied the same core range throughout the period they were monitored. Some subadult females did move into new areas, by a process of range extension rather than a single dispersive range shift. In contrast most males monitored for more than 6 months shifted their range, but the distances between successive seasonal range centres never exceeded 2.6 km and could not be reliably distinguished from adult seasonal movements. The range stability and slow dispersal rates of fallow deer should make them easier to control than the other common introduced deer species in New Zealand, and should make it practical to have different management objectives and regimes for adjacent catchments in the Blue Mountains.Manaaki Whenua -Landcare Research,
