The Role Of Indirect Transmission In The Epidemiology Of Bovine Tuberculosis In Cattle And White-Tailed Deer In Michigan, Amanda Elizabeth Fine

Michigan Bovine Tuberculosis Bibliography and Database

Understanding the epidemiology of Mycobacterium bovis transmission in Michigan is an essential component of nationwide efforts to control and eradicate bovine tuberculosis (TB). Determining the role of indirect transmission in bovine TB dynamics is a key to the application of epidemiologically effective methods of disease control in both livestock and wildlife populations. The objective of this dissertation was to characterize the persistence of M. bovis in the environment and its potential role in the indirect transmission of disease among and between cattle (Bos taurus and white-tailed deer (Odocoileus virginianus) in Michigan.
