Abstract
There is provided a vaccine material capable of providing a substantial level of protection against infection by enterotoxogenic organisms of Escherichia coli. The protecting means comprises pili of the infecting organism. The protection is given either by administering the pili directly to the subject to be protected or to a pregnant female where protection of the newborn is desired. In the case of piglets, where there is substantially no transplacental transfer of immunity from mother to offspring, the pili are administered to mothers, who are then caused to feed the offspring to be protected, whereby the immunization is transferred via the colostrum of the mother.
