Abstract

To improve the whole-cell pertussis vaccine we have studied the inactivation of the biological properties characteristic of Bordetella pertussis phase I bacteria, i.e. histamine-sensitizing, lymphocytosis-promoting and mouse protective activities, by treating a concentrated bacterial suspension with various concentrations of glutaraldehyde. Under the experimental conditions, treatment with 10 mM glutaraldehyde at 37 degrees C for 30 min resulted in a marked reduction of the toxic activities without grossly diminishing the protective potency. Further tests were performed on the stability of the protective potency, on the agglutinin production in mice, and on the freedom from abnormal toxicity in guinea-pigs.
