Apicomplexa in Australian livestock – concerns and knowledge gaps

Sign up or log in to save this to your schedule and see who's attending!

A number of Apicomplexan genera are known to occur in Australian livestock. Although Apicomplexan protozoa also infect poultry and pigs, this presentation is confined to cattle, sheep and goats. The parasites’ life histories vary from direct, single host life cycles, to complex life cycles involving several species of arthropod vectors. Livestock can act as either definitive, intermediate, or incidental hosts. Apicomplexans are final host specific and their target tissues range from erythrocytes, intestinal epithelium, lymphocytes, neurones, and striated muscle cells to the epidermis and sclera. Knowledge about their adverse impact on livestock production and reproduction varies. In addition, they may reduce the profitability of red meat for aesthetic reasons, or pose a potential zoonotic risk to consumers. Although certain life cycle stages may be macroscopically visible in some genera, most of them require microscopic, serological or molecular confirmation of their diagnosis
