title: Bacterin to control the vertical transmission of Mycoplasma gallisepticum in chickens.
abstract: A Mycoplasma gallisepticum bacterin was prepared and used in Mycoplasma gallisepticum (MG)-positive primary breeders to control vertical transmission of MG. Two generations were vaccinated, but the third generation was not vaccinated and was monitored serologically. Results showed no evidence of MG at 1 day, 6 weeks, 11 weeks, 16 weeks, or 31 weeks of age. This procedure may offer small breeder organizations and showbird fanciers a way to eliminate MG.
