Bovine Mycoplasmosis

Abstract

The bovine mycoplasmas interact in varying degrees with their host. This interaction can range from purely commensal in nature to one with devastating consequences for the host. In some disease processes the role of mycoplasma is well documented and straightforward. However, because of the commensal nature that can exist with many of the bovine mycoplasma species, even species considered to be highly pathogenic, it is not always clear what role, if any, these mycoplasmas play in some disease processes. There is still much to be learned about this delicate host-parasite relationship and the additional factors important in tipping the balance toward disease manifestation. Given the number of variables that are unknown, the practitioner must make decisions based on present knowledge. The decisions regarding treatment and management of disease are influenced by herd history, clinical findings, laboratory results and economic impact and often must be tailored for the individual situation.
