The issue of whether low-level tolerance to germicides selects for antibiotic-resistant strains is unsettled but might depend on the mechanism by which tolerance is attained. For example, changes in the permeability barrier or efflux mechanisms might affect susceptibility to both antibiotics and germicides, but specific changes to a target site might not. Some researchers have suggested that us...

Although it has long been realized that the fatty acids have excellent germicidal powers, except for the work done by Reid5 little study seems to have been made of them as a group. In particular, the relative parts played by the dissociated and undissociated fractions have not been investigated in detail, although the existence of this dual action has been recognized. Furthermore, information o...

The important part that fleas acd flies and mosquitoes and other small insects play in the spread of infectious diseases and complaints such as plague, enteric, typhus, malaria and summer diarrhoea is becoming more generally recognised every day ; indeed Sir Lauder Brunton speaks of fleas as a national danger (Tha Lancet, Nov. 9th, 1907), and the destruction of these insects is a problem which ...

UV radiation from the sun is the primary germicide in the environment. The goal of this study was to estimate inactivation of viruses by solar exposure. We reviewed published reports on 254-nm UV inactivation and tabulated the sensitivities of a wide variety of viruses, including those with double-stranded DNA, single-stranded DNA, double-stranded RNA, or single-stranded RNA genomes. We calcula...

background trachyspermum ammi or carum copticum, commonly known as ajowan or ajwain is a plant used as a spice. thymol, the major phenolic compound present in ajowan is known as a strong germicide and anti-spasmodic. it is also used for cleaning the wounds and treating skin infections. objectives here, we aimed to study the inhibitory effects of ajowan essential oil on microorganisms like esche...
