The Reverse Selective Bacteriostatic Action of Acid Fuchsin
1. The reverse selective action attributed to acid fuchsin can be explained on the basis of spore resistance. This action does not apply to the vegetative cells of Gram-positive spore bearers. It cannot be extended to include the Gram-negative spore bearers. 2. The selective action of acid fuchsin is that of an ordinary weak disinfectant and is not comparable to the selective action of the trip...
متن کاملThe Reverse Selective Bacteriostatic Action of Acid Fuchsin
1. Acid fuchsin possesses a bactericidal power, selective as between Gram-negative and Gram-positive spore-bearing aerobic organisms. The selective feature is the reverse of that of gentian violet. 2. This reverse selective activity is also possessed by simpler sulfonated substances and would appear to be dependent in some way on the presence of SO(3) radicals. 3. Selective penetration, if at a...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولAlkyl Sulfates: Their Selective Bacteriostatic Action *
Detailed studies of the bactericidal action of soaps have been made by numerous observers. Among them the most recent include those by Tilley and Schaffer, Walker, Eggerth, and Schaffer and Tilley. In general, such action increases with the number of carbon atoms in the fatty acid up to a maximum which depends upon factors such as the hydrogen ion concentration, the nature of the test organism,...

Cybulska, Janina (State Institute of Hygiene, Warsaw, Poland), and J. Jeljaszewicz. Bacteriostatic activity of serum against staphylococci. J. Bacteriol. 91:953-962. 1966.-Antistaphylococcal activity of normal serum against strains exhibiting various patterns of coagulase, clumping-factor, and staphylokinase production is not connected with the presence of these factors. Purified coagulase does...
