title: Mycoplasma infection of geese. II. Studies on pathogenicity of mycoplasmas in goslings and goose and chicken embryos.
abstract: Of various mycoplasma strains of goose original, axanthum strains (609 and 612) caused the death both of goose and chicken embryos, A. laid-lawii strain (606) killed only goose embryos, whereas M. gallinarum (598) failed to kill either. Infection of 3-day-old goslings with these mycoplasmas resulted in no mortality but lesions were produced with A. axanthum in 9 of 10 birds. Less severe lesions were seen in fewer birds infected with other strains. Dual infection of 3-day-old goslings, with maternal antibody to goose parvovirus, with M. gallinarum (598) or A. axanthum (612) and a virulent parvovirus resulted in some death and all birds showed lesions.
