Changing expectations in the control of Mycoplasma gallisepticum
1University of Georgia, Department of Avian Medicine, Athens 30602-4875, USA.
Abstract:
Mycoplasma gallisepticum (MG) is traditionally controlled by maintaining MG-free flocks on single-age production sites and maintaining them MG-free utilizing good biosecurity and a consistent serological monitoring program. In recent years, several changes have taken place which have changed our ways about thinking about MG control. There have been significant improvements in detection methods. For example, polymerase chain reaction now represents a rapid and sensitive method for detecting the organism. ELISA kits are now much improved. DNA technology now allows rapid identification of specific strains (DNA finger-printing) for epidemiological studies. On the other hand, the industry world-wide is growing rapidly, and there are huge populations of poultry in small geographic areas, making control utilizing biosecurity more and more difficult. Also, multi-age production sites are becoming more common, especially in commercial egg production. This has led to increased usage of live MG vaccines, which are effective in controlling economic losses and may be used as tools in eradication programs.
