title: Studies on the control of Mycoplasma gallisepticum in hatching eggs.
abstract: Lincomycin-spectinomycin, while effective in eliminating Mycoplasma gallisepticum from hatching eggs when administered via the yolk sac, had a marked deleterious effect on hatch-ability when given by this route. On the other hand when lincomycin-spectinomycin was injected into the air cell there was a reduction in the level of experimental infection with an acceptable effect on hatchability.
