| Abstract: | Chlamydia psittaci, a zoonotic bacterium, is the causal agent of enzootic abortion of ewes, an important disease of sheep in many European countries. The major thrust of current chlamydial research is directed towards the human pathogen Chlamydia trachomatis. This review attempts to bring together relevant information concerning the host immune response to all members of the genus Chlamydiae and show how this has led to an increased understanding of the ovine humoral and cell mediated immune responses to C. psittaci while emphasising areas where there is still a lack of knowledge. Specifically the review looks at the common immuno-accessible antigens of the Chlamydiae and the antibody responses produced during infection, as well as covering the role of T cells and cytokines in the protective immune response. |
