Spread of the newly emerging infectious laryngotracheitis viruses in Australia.

Infectious laryngotracheitis (ILT) is a significant viral disease of chickens in many countries around the globe. In this report the status of ILT in Australia has been used as a model to evaluate the evolution of the ILT viruses (ILTVs). Due to its geographical isolation, Australia harbored a distinct lineage of ILT viruses (ILTV) up to 2007.

High-resolution melting-curve analysis of obg gene to differentiate the temperature-sensitive Mycoplasma synoviae vaccine strain MS-H from non-temperature-sensitive strains.

Temperature-sensitive (ts+) vaccine strain MS-H is the only live attenuated M. synoviae vaccine commercially available for use in poultry. With increasing use of this vaccine to control M.

Combination of differential growth at two different temperatures with a quantitative real-time polymerase chain reaction to determine temperature-sensitive phenotype of Mycoplasma synoviae.

Mycoplasma synoviae infections result in significant economic losses in the chicken and turkey industries. A commercially available live temperature-sensitive (ts (+)) vaccine strain MS-H has been found to be effective in controlling M. synoviae infections in commercial layer and broiler breeder farms in various countries, including Australia.
