The Ring-Necked Pheasant (<i>Phasianus colchicus</i>) Industry within the United Kingdom and the Threat Posed by <i>Mycoplasma gallisepticum</i>: A Review

Abstract

In ring-necked pheasants (Phasianus colchicus), Mycoplasma gallisepticum (MG) infection is frequently associated with infectious sinusitis. This condition causes swelling of the infraorbital sinuses, upper respiratory distress, depression and variable levels of mortality, and is considered one of the most important clinical and economic diseases of pheasants. This review provides a brief overview of the structure of the UK pheasant industry, with reference to the various stages within the supply chain, common diseases and challenges facing the industry. The current understanding of MG transmission, prevalence, clinical expression, diagnosis and control strategies in pheasants is subsequently summarised. In addition, this review aims to assess the current gaps in knowledge relating specifically to MG in pheasants, with reference and extrapolation where appropriate to data gathered from other species.
