title: Activity of macrophages from guinea pigs at various periods after infection with Rickettsia prowazeki.
abstract: The function of peritoneal macrophages from Rickettsia prowazeki-infected guinea pigs at various intervals of postinfection immunity was studied. The activity of macrophages in immunized animals was higher than in non-immunized ones; it was the highest in the period of the highest level of immunity and high levels of complement-fixing antibodies.
