MICROBIC VIRULENCE AND HOST SUSCEPTIBILITY IN PARATYPHOID-ENTERITIDIS INFECTION OF WHITE MICE : VII. THE EFFECT OF SELECTIVE BREEDING ON HOST RESISTANCE. FURTHER STUDIES.
1. Survivors of an experimental mouse typhoid infection, selected and bred for a number of consecutive generations, give birth to offspring which are more resistant to the disease than a random group of the same inbred race. 2. Offspring of females most susceptible to this infection give birth to individuals which are more susceptible than a group of similar unselected mice.
