Lymphocytosis-Promoting Factor Produced by Bordetella Pertussis Partial Purification and Characterization

A Preliminary Report on the Neutralization of the Lymphocytosis-Promoting Factor (Lpf) With Anti-LPF Serum

“…Though LPF has shown every property common to exotoxins (Iwasa et al, 1968;Ishida , 1968), the recovery from the LPF-induced lymphocytosis and the body weight decrease was independent of the intervals between the LPF and the anti-LPF serum inoculation , with the exception of two groups in which the serum was given 1 or 2 days after LPF and the dody * The dose of LPF at which the mean body weight of mice would neith er increase nor decrease from the 2nd day to the 4th day.…”

Effects of the Lymphocytosis-Promoting Factor of Bordetella Pertussis on Antibody Production in Mice

“…The temporal relationship between LPF administration and antigenic stimulus was taken into special account. (Iwasa et al, 1966 et al, 1962;Ishida, 1968).…”

Lienotoxicity Of Bordetella Pertussis In Mice

“…After intravenous injection of the toxin D-30-1, the body weight gains were suppressed to a varying extent depending upon the dose of toxin, but the late type of weight loss described by Iwasa et al (1966Iwasa et al ( , 1968) and Ishida .…”
