Excerpt from Inheritance of Resistance to Bacterial Infection in Animals: A Genetic Study of Pullorum Disease Because of its simplicity and the accuracy with which it could be applied, survival was used thruout these tests as the basis for selecting resistant breeding stock and for judging the reaction of individuals to inoculation with the infecting organism. Incidentally some data are presented concerning the effect of inoculation on growth retardation and the relative susceptibility of the progeny of growth-retarded dams and the progeny of dams which, judged by their larger growth, had been less affected by inoculation.
