Loss of humoral immune competence in T. brucei-infected mice is associated with the apoptotic depletion of splenic transitional, marginal zone and follicular B cells as well as a depletion of CD8+ T cells. This occurs rapidly after infection and impairs responses to vaccine antigens in addition to responses to newly arising VSG antigenic variants, leading to uncontrolled parasite growth and death of the infected mice. Infection-induced B2 B cell and CD8+ T cell loss requires the presence of a novel population of natural killer (NK) cells and is mediated by a perforin-dependent process consistent with perforin- and …

Mycobacterial species are ubiquitous in nature and a worldwide concern for human and animal health. The major mycobacterial infections in animals are Johne’s disease (JD) and bovine tuberculosis (bTB). Controlling these infections is difficult due to the lack of highly sensitive and sensitive diagnostic test. Currently available diagnostic tests have to be carried out in laboratory settings with well experienced and trained examiners. My goal is to develop a sensitive on-site (in-field) device for diagnosis of Johne’s disease and bovine tuberculosis. The specific aims of this thesis were (1) to review currently-used or recently developed diagnostic tests for mycobacterial infections, …
