Following the intravenous injection of streptozotocin into rats, postprandial hyperglycaemia was sustained from 24 hours over a subsequent period of some weeks and the rats were glucose intolerant. When streptozotocin was similarly injected into pertussis-sensitized or hydrocortisone treated rats, the postprandial hyperglycaemia observed at 24 hours did not persist, but showed a progressive decline until near normoglycaemia was obtained a week later. These animals manifested normal glucose tolerance one week after streptozotocin. Thus, a spontaneous recovery from streptozotocin-induced diabetes occurred under these conditions. This spontaneous recovery from diabetes was associated with hyperinsulinaemia in the fed state.

The defect in Leiner's disease, which presents in early infancy with extensive dermatitis, diarrhoea, and failure to thrive, has been attributed to a defect of the fifth component of complement (C5). We report 2 brothers with extensive dermatitis and dysgammaglobulinaemia. Both died. The older showed symptoms of Leiner's disease: C5 tests were not performed. The younger had extensive dermatitis and was found to have the C5 defect. He developed normally, but died suddenly with pertussis. We postulate that the C5 defect is not the sole cause of Leiner's disease as has been suggested, but that hypogammaglobulinaemia or other lymphoid deficiency is also required for its expression.

Twelve inbred rat strains were tested for their susceptibility to autologous immune complex glomerulonephritis (AIC) after a single injection of a primary tubular epithelial fraction emulsified in Freund's complete adjuvant. Six strains (Lewis, AS, BDV, L.BDV, AS2, L.AS2) showed high responsiveness in terms of proteinuria and immunohistological changes, which could be observed after 3 months. Strains BN, AVN and DA were completely resistant, even after 6 months of observation. An additional adjuvant (pertussis vaccine) did not break non-responsiveness in one of these strains (BN). Strains which share the Lewis strain genetic background (L.BN, L.AVN and L.WP) seemed to be at least weakly susceptible to AIC. A close association between susceptibility and the major histocompatibility haplotypes is demonstrated in segregation studies involving Lewis, L.BN and BN rats. A threshold model of AIC susceptibility, based on the action of major histocompatibility-linked genes and background genes, is suggested.

The effects of the route of the injection and adjuvants on the immune response of guinea pigs were investigated at various stages of immune response to tetanus toxoid. Delayed-type hypersensitivity (DH) was observed as the first immune response to the toxoid before initiation of antitoxin production. The DH reaction was weak when plain toxoid was administered subcutaneously. Water-in-oil in water (w/o/w) enhanced greatly the reactivity of the immunized animals; pertussis vaccine, endotoxin and aluminium showed adjuvanticities in this order. The foot pad (fp) injection of plain toxoid promoted remarkably the induction of DH. The reactivity was enhanced considerably by w/o/w and to a less extent by aluminium. However, pertussis vaccine showed an adverse effect on DH by the fp route. Active cutaneous anaphylaxis (ACA) induced by the subcutaneous route was enhanced by w/o/w, endotoxin, pertussis vaccine and, to a less extent, by aluminium. The fp route compared with the sc route enhanced ACA by plain toxoid; w/o/w and aluminium but not endotoxin and the vaccine showed adjuvanticities. The influences of adjuvants and the route of injection on Arthus reactions were inconsistent. The effect of adjuvants on antitoxin production was quite different from that on DH when antitoxin was produced abundantly. Aluminium showed consistently a potent adjuvanticity, but activities of w/o/w, endotoxin and pertussis vaccine were inconsistent 4-6 weeks after the primary stimulus by the subcutaneous route. The adjuvant effect became less significant in the secondary response. The fp route was more favorable for antitoxin production than the subcutaneous route with most adjuvants except pertussis vaccine added to tetanus toxoid. Antitoxin production by plain toxoid was very poor when administered intraperitoneally; aluminium and w/o/w but not endotoxin showed a remarkable adjuvanticity for the antitoxin production.

When mice were injected intracerebrally with doses of Bordetella pertussis vaccine greater than 5 ImD 50 and challenged intracerebrally 14 days later with virulent B. pertussis there was an immediate reduction in the numbers of organisms. An analysis of this in vivo bactericidal effect has shown that large doses of an unrelated vaccine, Salmonella typhosa, equivalent in cell mass to about 50 ImD 50 of B. pertussis vaccine can achieve this effect, so for such doses the effect must be partly non-specific. This action is not maintained and so is not ultimately protective. Local immunoglobulin was also demonstrable 14 days after 300 ImD 50 of B. pertussis vaccine but following smaller doses of 10-20 ImD 50 it could not be found until after the mice had been infected and the blood-brain barrier impaired. A similar immediate reduction in the numbers of infecting organisms inoculated 1 day after vaccination has been shown to follow very small, non-protective doses of vaccines unrelated to B. pertussis and to be achieved with lipopolysaccharide and endotoxin isolated from B. pertussis. Brains were not sterilized and only in mice receiving protective B. pertussis vaccine was the lowering of infection maintained beyond 2 days and the brains eventually sterilized. The antibody passively protecting mice against intracerebral infection was found in the 19S and 11 S globulin fractions of the serum of once-vaccinated mice and in the 11 S and 7 S fractions of the serum of rabbits and ascitic fluid of mice receiving repeated doses of vaccine. The IgM probably eliminated infections by immediate sterilization but had to be present locally to do so since it was unable to pass from the circulation into the brain, and was therefore inactive when injected intraperitoneally. The IgA and IgG were not so restricted and both the 11 S and 7 S globulins were capable of exerting an immediate suppressive effect on infecting organisms. The 7 S globulin was also capable of a maintained or delayed suppressive effect. Lymphocytes from fully protected once-vaccinated mice, transferred 2-3 weeks after intraperitoneal vaccination, were able to confer some protection when injected intraperitoneally or intracerebrally into recipient mice infected 2 weeks after transfer. Homologous, non-concentrated antiserum from once-vaccinated mice, injected intraperitoneally 1 hr. before infection sometimes augmented the transferred immunity, whereas alone it was inactive.

To define the role of adenoviruses in the pertussis syndrome, a study was done of a group of 134 children with clinical pertussis and a healthy control population of similar age, race, sex, and socioeconomic status. Adenovirus infections occurred in 30 (22.4%) of 134 patients with the pertussis syndrome and 5 (4.9%) of 101 control subjects (p smaller than 0.001). B. pertussis was recovered from 46 (34.3%) patients, and from 18 (39.1%) of these patients adenoviruses were also isolated. Although adenovirus infections also occurred in patients with the pertussis syndrome with negative cultures for B. pertussis, the rate, 12 of 88 patients (13.6%), was significantly lower (p smaller than 0.001). The clinical course was similar irrespective of the results of bacterial or viral cultures. These data substantiate the frequent association of adenoviruses with the pertussis syndrome, It would appear that adenoviruses do not usually have an independent role in the pathogenesis of the pertussis syndrome since we found them so commonly to be one agent in a mixed infection.

Inheritance of responsiveness to histamine-sensitizing factor of pertussis bacilli (HSF) was investigated in (C3H/HeJ times C57BL/6J)F1 hybrids, backcross progeny of this hybrid to C57BJ/6J parent (C3H/HeJ times DBA/2J)F1 hybrids, and in backcross progeny of this hybrid to DBA/2J parent. It was found that transmission is not by virtue of a single autosomal dominant gene, as has been postulated. Rather, inheritance of responsiveness to HSF is far more complex, probably involving polygenic transmission.

Animal experiments have shown that respiratory administration of pertussis antigen induces a protective immune response. In this study pertussis antibody in human respiratory secretions was measured and the response to aerosol and intramuscular pertussis immunization investigated. Substanial increases in this antibody occurred after aerosol immunization but no changes were found in serum antibody. The reverse was observed after intramuscular pertussis vaccine in adults but not with aerosol immunization. The latter method may be of value for paediatric medical and nursing personnel exposed to the risk of pertussis infection.

The authors elaborated a method of obtaining pertussis soluble antigenic complex by dialysis through the cellophane membrane against the physiological saline at a temperature of 4 degrees C. An antigen which was active in the passive hemagglutination and neutralization of antibodies tests was revealed in the dialyzate. The amount of this antigen in the dialyzate increased gradually up to the 7th day and then became stabilized. The serological activity of the antigen after evaportation increased 4-16 times. The results of the antibody neutralization test pointed to the presence in the dialysate of substances common to those contained in the 1a and 1Da fractions isolated from the pertussis bacteria with the aid of ammounium sulfate.
