Correlation between the bacterioclastic action of a bis-quaternary ammonium compound and outer membrane proteins.
Bis-quaternary ammonium compounds (bis-QACs) have the ability to cause a rapid and abundant leakage of the turbid materials from cells, and such a bacterioclastic ability leads to a potent bactericidal activity. In order to clarify the detailed mechanism of the bactericidal action of bis-QACs, the correlation between the bacterioclastic action of 4,4'-(1,6-hexamethylenedithio)bis(1-octylpyridin...

متن کاملAction of disinfectant quaternary ammonium compounds against Staphylococcus aureus.
Mode-of-action studies concluded that alkyldimethylbenzylammonium chloride (ADBAC) (a blend of C(12), C(14) and C(16) alkyl homologues) and didecyldimethylammonium chloride (DDAC) are both membrane-active agents, possessing subtly different modes of action reflecting early cell interactions against Staphylococcus aureus. ADBAC and DDAC exhibited similar MIC behaviors from 0.4 ppm to 1.8 ppm ove...
متن کاملVirucidal activity of a quaternary ammonium compound disinfectant against feline calicivirus: a surrogate for norovirus.
BACKGROUND Norovirus, formerly known as Norwalk virus, is an important cause of gastroenteritis outbreaks in hospitals, food services, schools, and cruise ships. Infection control practices by using disinfectants to eliminate noroviruses from surfaces and environmental samples reduce the morbidity and spread of virus outbreaks. There are not many commercial disinfectants effective against norov...
متن کاملEffect of a quaternary ammonium germicide on electrophoretic mobility of Escherichia coli in various salt solutions.
Quaternary ammonium compounds, effective as sanitizing agents for food plant equipment under certain conditions, are not well suited as sanitizers for water of high mineral content. Mueller and Seeley (1951) have demonstrated under controlled conditions that various metallic cations can decrease the germicidal action of a quaternary in solution. Knowledge of how such interference takes place co...
