MICROBIC VIRULENCE AND HOST SUSCEPTIBILITY IN PARATYPHOID-ENTERITIDIS INFECTION OF WHITE MICE : XI. SEASONAL VARIATION IN THE SUSCEPTIBILITY OF DIFFERENT STRAINS OF MICE TO PER OS INFECTION WITH THE TYPE II BACILLUS OF MOUSE TYPHOID (BACILLUS PESTIS CAVIAE). FURTHER STUDIES.
Four unrelated strains of mice were tested over a period of 1 year for their seasonal variation in susceptibility to per os feeding with a culture of Bacillus pestis caviae of known virulence. Certain consistent fluctuations, determined to be in general agreement with those already recorded in a previous paper, were found and described.
