Abstract

Infection with Mycoplasma gallisepticum induces severe lymphoproliferative lesions in multiple sites along the respiratory tract in chickens and turkeys. These immunopathological responses have been well-characterized in chickens, but have not been studied closely in turkeys. The aim of the study described here was to examine the immune responses of turkeys after live vaccination and infection with M. gallisepticum. In a strain comparison study, the mean log10 antibody titre of birds exposed to an aerosol culture of M. gallisepticum strain Ap3AS was found to be significantly higher at day 14 than that of birds exposed to strain 100809/31. In a dose-response study, there was a significant dif..
