Abstract
Summary
1. Gram positive cocci and gram negative bacilli were tested turbidimetrically for aureomycin sensitivity. The inhibitory levels were .02 to .05 μg per ml for S. aureus, 0.1 μg per ml for enterococcus, and 0.5 μg per ml for Sal. Panama and E. coli.
2. Aureomycin was not inhibited by the presence of blood or serum in the medium.
3. Increased length of incubation and addition of serum or blood to the medium resulted in higher levels of inhibition, particularly with the plate method. An explanation of this effect is offered.
4. Tryptone glucose extract agar was used for a plate method, Values were higher and less consistent than with the turbidimetric technic
