This work summarizes the informations regarding 67,767 Salmonella strains isolated in continental France from 1981 to 1983. The frequencies of O groups, of subspecies, of the 62 serotypes most frequently isolated among the 376 identified are reported. The graphs representing the annual occurrence of some serotypes show that some serotypes are considerably expanding, some disappeared after being quite frequent, and some show marked fluctuations by successive waves.
