ABSTRACT:
A method for large scale cultivation and attenuation of L. intracellularis bacteria by inoculating cells with L. intracellularis bacteria to infect the cells, incubating the infected cells in a reduced oxygen concentration and maintaining the infected cells in suspension. Anti-L. intracellularis vaccines are prepared from cultures grown in suspension. Diagnostic agents are also disclosed.
