Local footpad infection in mouse was investigated with 55 clinically isolated strains of Staphylococcus aureus. When 10(7) viable cells were inoculated into the footpad, local swelling and bacterial growth resulted after 24 hr. With a dose of 10(6) cells, moderate swelling was observed after a few hours but the reaction had almost disappeared after 24 hr. About 75% of the staphylococcal strains tested caused footpad edema in mice at doses of 10(7) cells. A statistical comparison of the virulence of the organisms on intravenous and intraperitoneal injection with that in inducing footpad swelling is also reported.
