SELECTIVE ACTION OF THALLIUM ACETATE AND CRYSTAL VIOLET FOR PLEUROPNEUMONIALIKE ORGANISMS OF HUMAN ORIGIN

Abstract
The noninhibitory action of crystal violet for pleuropneumonia-like organisms is influenced by the total protein content of the culture medium, while that of thallium acetate is not. The antibacterial effect of thallium acetate appears to be similar to the combined effects of crystal violet and K tellurite. Of the 12 spp. of bacteria tested, only Streptococcus faecalis and S. pyogenes appear to be unaffected by thallium acetate.
