The nature of the pathogenesis and of the prolonged immunity of whooping cough has not been clearly defined. The literature of Bordetella pertussis indicated that only the antigen that induces histamine sensitization, lymphocytosis, and other biological reactions in mice is the cause of the harmful effects and prolonged immunity of whooping cough. This antigen has the general characteristics of bacterial protein exotoxins that cause the harmful effects of infectious diseases such as diphtheria and tetanus. It is proposed that this antigen, which is histamine-sensitizing, lymphocyte-leukocyte-promoting, and islets-activating (HSF-LPF-IAP), be designated pertussis toxin. Agglutinogen, hemagglutinin, and heat-labile (at 56 C) and heat-stable (at 100 C) toxins are no doubt interrelated with the immunologic and/or toxic reactions of whooping cough. It appears that the first defense against the disease is the antibody that prevents adhesion of the bacteria to the cilia of the respiratory epithelium and that the second defense is the antitoxin against pertussis toxin (HSF-LPF-IAP).

The combined diphtheria-pertussis-tetanus and combined diphtheria-pertussis vaccines, of which the contents of endotoxin, LPF and HSF were reported in the previous paper, have been tested for the respective potencies of pertussis, diphtheria and tetanus components. In order to obtain some information concerning possible adjuvanticities of the toxic components of pertussis cells, relationship between respective toxic activities and the potencies of the respective antigenic components were tested by applying the multiple regression analyses. The results showed that the effects of the toxic components were fairly complicated. Within the ranges of contents of the respective toxic components of the vaccines used in the present experiment, LPF appeared to enhance all the three potencies as the content increased, while the effects of endotoxin and HSF were either enhancing or suppressive depending on the antigenic components.

Susceptibility to Bordetella pertussis-induced sensitivity to serotonin was found to be associated with the H-2 gene complex in mice. H-2 congenic and independent strains which possess the H-2b and H-2s haplotypes were susceptible to serotonin sensitization by pertussigen (P-HSF) while mice with the H-2k and H-2d haplotypes were resistant. The gene or genes which control susceptibility were found to map to the H-2SbDb end of the H-2 complex; susceptibility appears to be inherited as a co-dominant trait. These findings indicate that HLA typing may be of value in predicting or interpreting possible adverse reactions to pertussis vaccine or infection in humans.

Susceptibility to the induction of murine autoimmune orchitis was found to be associated with the locus controlling Bordetella pertussis-induced sensitivity to the vasoactive amine, histamine. Only those inbred and H-2 congenic strains of mice possessing both the H-2d haplotype and the locus for susceptibility to B. pertussis-induced sensitivity to histamine developed autoimmune orchitis. In addition, segregation analysis of backcross generation mice also demonstrated a high degree of correlation between susceptibility both to disease and to histamine sensitization, which was indicative of additional multigene control. Pertussigen-histamine sensitization factor (P-HSF) was only effective in eliciting disease when it was administered on the same day, or within a period up to 6 days following sensitization with mouse testicular homogenate-emulsified in complete Freund's adjuvant. P-HSF induced sensitivity to histamine was not found to be associated with an increase in the vascular permeability of target tissue. Thus, B. pertussis-induced sensitivity to histamine appears to play a more crucial role during the sensitization phase of autoimmune orchitis induction, rather than at the inflammatory or effector phase of the disease.

The effect of B. pertussis vaccine on the serum glucose level of mice was investigated. The results show that at least two components in the vaccine interfere with glucose metabolism. A heat-stable component which is assumed to be LPS induced hypoglycemia 3-5.5 h after inoculation, especially in LPS-sensitized mice. A heat-labile component which is possibly equivalent with the LPF/HSF/IAP complex, is responsible for persistence of the hypoglycaemia for at least 6 days. If hypoglycaemia contributes to the neurological side effects after pertussis vaccination both components have to be considered as being responsible for these effects.

Bordetella pertussis is composed of a series of active components: (1) a heat-labile or dermonecrotic toxin (HLT); (2) a lipopolysaccharide endotoxin (LPS); (3) pertussis toxin; (4) filamentous hemagglutinin (FHA); (5) agglutinogens; (6) outer membrane proteins; (7) adenylate cyclase; and (8) tracheal cytotoxin. Pertussis toxin (PT), also called lymphocytosis-promoting factor (LPF), encompasses a series of biological activities including: (1) histamine-sensitization (HSF); (2) leukocytosis-promoting activity (LPF); (3) LPF-hemagglutinin (LPF-HA); and (4) pancreatic islet-activating protein (IAP). The heat-labile toxin is inactivated during vaccine production. Pertussis toxin is inactivated when heated to 80 degrees C for 30 min and endotoxin at a temperature greater than 120 degrees C for 30 min. The effect of pre- and post-heat treatment on DTP vaccine, Bordetella pertussis endotoxin, pertussis toxin and a pertussis toxin/endotoxin combination, was determined as related to: (1) paw swelling response; (2) LAL activity (endotoxin); and (3) HSF activity. With the exception of DTP and B. pertussis endotoxin, the average paw swelling response after injection of non-treated and heat-treated test samples was similar to the saline control at all measured time intervals. Contrary to anticipated results, heat treatment enhanced the paw-swelling response of DTP vaccine and B. pertussis endotoxin. Endotoxin levels, as measured by LAL, were significantly lower after heat-treatment, with the exception of B. pertussis endotoxin and the E-1 control. The addition of pertussis toxin, B. pertussis endotoxin or pertussis toxin/endotoxin did not restore LAL values to the levels seen for non-treated DTP vaccine.(ABSTRACT TRUNCATED AT 250 WORDS)
