The Selective Bactericidal Action of Gentian Violet
During the course of an experimental study of bacteriuria, specimens of urine thought to contain Bacillus prodigiosus which had been injected into the circulation became contaminated with Bacillus subtilis. In an effort to rid them of this contamination, the effect on the two organisms of a number of common dyes was studied and a striking selective power possessed by gentian violet was brought ...
متن کاملA Study of the Bactericidal Action of Ultra Violet Light
1. Wide differences in the intensity of incident ultra violet energy are not accurately compensated by corresponding changes in the exposure time, so that the Bunsen-Roscoe reciprocity law does not hold, strictly, especially for bactericidal action on young, metabolically and genetically active bacteria. In the present series of experiments, however, the energies used at various wave lengths di...
متن کاملBactericidal Action of Stains Closely Allied to Gentian Violet.*
The recent observation of a sharp selective bactericidal property possessed by gentian violet 1 raised the question as to which part of the gentian violet molecule was responsible for the sensitive affinity. It seemed wise to attack this problem by studying substances closely allied to gentian violet in chemical structure, 2 and the results obtained will be briefly reported in the present commu...
متن کاملBactericidal versus Bacteriostatic Antibiotic Therapy
/Ag/ml; strain2-MIC 1 ,g/ml, MBC 2 ,g/ml. Animals were treated with either ampicillin or chloramphenicol in dosages that achieved a peak bactericidal effect in cerebrospinal fluid (CSF) for ampicillin against both strains. Two different dosages were used for chloramphenicol. The first dosage achieved a peak CSF concentration of 4.4±1.1 gg/ml that produced a bacteriostatic effect against strainI...
متن کاملFollowing the mechanisms of bacteriostatic versus bactericidal action using Raman spectroscopy.
Antibiotics cure infections by influencing bacterial growth or viability. Antibiotics can be divided to two groups on the basis of their effect on microbial cells through two main mechanisms, which are either bactericidal or bacteriostatic. Bactericidal antibiotics kill the bacteria and bacteriostatic antibiotics suppress the growth of bacteria (keep them in the stationary phase of growth). One...
