Abstract
AN important property of certain organic dyes is their differential antiseptic action. Thus, varieties of B. coli commonly met with in the intestine are more susceptible to the inhibitory action of the tetræthyl-diamidotriphenylmethane derivative, “brilliant green,” than are typhoid or paratyphoid bacilli. The use of a fluid culture medium containing this dye (along with telluric acid) facilitates greatly the isolation of scanty typhoid and paratyphoid bacilli from faæ, since the growth of the various members of the coli group can be restrained, while the organisms in question proliferate actively. The detection of cases of typhoid infection, e.g. in “carriers,” which is frequently a difficult bacteriological problem, can be materially simplified by this procedure. But our supplies of brilliant green have hitherto been derived from Germany, and I shall be indebted to your readers for information as to whether this dye is prepared in a fairly pure state by anyone in this country.
