Mycoplasma gallisepticum in pheasants and the efficacy of tylvalosin to treat the disease.

Infectious sinusitis, a common condition seen in adult pheasants, is primarily caused by Mycoplasma gallisepticum. The aims of the present study were to investigate the pathogenicity of M. gallisepticum in 14-day-old pheasants and evaluate the macrolide antibiotic tylvalosin (TVN) as a treatment for infectious sinusitis.

Analysis of the 16S to 23S rRNA intergenic spacer region of Mycoplasma synoviae field strains.

Mycoplasma synoviae has been associated with economic loss in the chicken and turkey industries. The molecular characterization of M. synoviae at strain level allows the analysis of relationships between strains that may be valuable in epidemiological investigations.
