Experimental Deer-To-Deer Transmission Of Mycobacterium Bovis, Mitchell V. Palmer, Diana L. Whipple, W. Ray Waters
Michigan Bovine Tuberculosis Bibliography and Database
Objective—To determine whether Mycobacterium bovis can be transmitted from experimentally infected deer to uninfected in-contact deer.
Animals—Twenty-three 6-month-old white-tailed deer.
Procedure—On day 0, M bovis (2 X 108 colony-forming units) was administered by intratonsillar instillation to 8 deer; 3 control deer received saline (0.9% NaCl) solution. Eight in-contact deer were comingled with inoculated deer from day 21. On day 120, inoculated deer were euthanatized and necropsied. On day 180, 4 in-contact deer were euthanatized, and 4 new incontact deer were introduced. On day 360, all in-contact deer were euthanatized. Rectal, oral, and nasal swab specimens and …

During a survey of carnivores and omnivores for bovine tuberculosis conducted in Michigan (USA) since 1996, Mycobacterium bovis was cultured from lymph nodes pooled from six coyotes (Canis latrans) (four adult female, two adult male), two adult male raccoons (Procyon lotor), one adult male red fox (Vulpes vulpes), and one 1.5-yr-old male black bear (Ursus americanus). One adult, male bobcat (Felis rufus) with histologic lesions suggestive of tuberculosis was negative on culture but positive for organisms belonging to the Mycobacterium tuberculosis complex when tested by polymerase chain reaction. All the …
Bovine Tuberculosis In Brushtail Possums (Trichosurus Vulpecula): Studies On Vaccination, Experimental Infection, And Disease Transmission, L. A. L. Corner
Bovine Tuberculosis In Brushtail Possums (Trichosurus Vulpecula): Studies On Vaccination, Experimental Infection, And Disease Transmission, L. A. L. Corner
Michigan Bovine Tuberculosis Bibliography and Database
The objectives of the research program were to obtain a better understanding of BCG as a tuberculosis vaccine in possums, and assess its potential as a tool for controlling tuberculosis in wild possum populations. A series of vaccination and challenge experiments were conducted, as well as studies on alternative experimental infection procedures. The program included two field studies, one on the epidemiology of tuberculosis in a population of possums regenerating after localised possum eradication, and the other examined the efficacy of BCG vaccine in a wild population in which tuberculosis was endemic.
The first experiments confirmed the earlier published findings …
Movement Patterns And Behavior At Winter-Feeding And Fall Baiting Stations In A Population Of White-Tailed Deer Infected With Bovine Tuberculosis In The Northeastern Lower Peninsula Of Michigan, Mark Stephen Garner
Michigan Bovine Tuberculosis Bibliography and Database
In 1994 bovine tuberculosis (Mycobacterium bovis) was discovered in a single free ranging white-tailed deer (Odocoileus virginianus) in northeastern Michigan (Deer Management Unit 452 @MU 452)). By the end of the 2000 hunting season, 325+ deer within the DMU 452 had been detected with M. bovis and it was generally believed that the disease had radiated from a single focus of infection. However, the presence of three TB positive deer discovered in 1999 well outside of DMU 452 suggested that M. bovis may be endemic at extremely low levels in Michigan white-tailed deer.
The primary mode …
Tuberculin Skin Testing In White-Tailed Deer (Odocoileus Virginianus), Mitchell V. Palmer, Diana L. Whipple, W. Ray Waters

The comparative cervical skin test for antemortem diagnosis of tuberculosis was done 169 times on 116 different white-tailed deer of known Mycobacterium bovis infection status. The sensitivity and specificity were 97 and 81%, respectively. The magnitude of change in skin thickness at test sites was not significantly influenced by dosage of inoculum, dissemination of the disease process, or repeated skin testing. However, the magnitude of change in skin thickness was significantly greater in deer infected for less than 109 days than in deer infected for more than 109 days. As used in the present study, the comparative cervical skin test …
