PG - 243-50 AB - We compared the protective activities of fimbrial hemagglutinin (FHA) and pertussigen and their respective antibodies in mice infected intracerebrally with Bordetella pertussis. We found that mice were protected by a 1.7-microgram/mouse dose of pertussigen which was free of detectable FHA and was detoxified by treatment with glutaraldehyde. A pertussigen preparation made from cells grown in shake cultures that did not contain demonstrable FHA protected mice at a dose of 1.4 microgram/mouse. FHA at a dose of 10 microgram/mouse protected mice from intracerebral infection, but it also sensitized mice to histamine at a dose of 2 micrograms/mouse, which indicated that it was contaminated with pertussigen. When FHA was obtained free of demonstrable pertussigen, it failed to sensitize mice to histamine at a dose of 30 micrograms/mouse and to protect mice from infection at a dose of 12 micrograms/mouse (largest doses tested). Passive protection tests with antisera known to contain antibodies to pertussigen protected mice from intracerebral infection, whereas sera lacking anti-pertussigen antibodies but containing high concentrations of anti-FHA antibodies did not protect mice. The most important antigen for the immunization of mice against intracerebral infection with B. pertussis appears to be pertussigen.
