Virus Inactivation Kinetics
At the session of the Research Group of the Standing Technical Committee of the European Commission for the Control of Foot-and-Mouth Disease in Chania, Crete, Greece, FMDV inactivation kinetics were again discussed and it was concluded that more experimental data was needed but that existing data should be thoroughly reviewed and be the basis for subsequent specific recommendations for experim...
متن کاملInactivation of Cryptosporidium parvum Oocysts by Ammonia.
The survival of Cryptosporidium parvum oocysts in soil and water microhabitats may be affected by the environmental production and release of free ammonia. The objective of this study was to determine the effects of increasing free ammonia concentrations and times of exposure on oocyst viability. Wild-type oocysts were obtained from naturally infected calf feces by chemical (continuous-flow) ce...
متن کاملSuicidal inactivation and labelling of ammonia mono-oxygenase by acetylene.
Acetylene brings about a progressive inactivation of ammonia mono-oxygenase, the ammonia-oxidizing enzyme in Nitrosomonas europaea. High NH4+ ion concentrations were protective. The inactivation followed first-order kinetics, with a rate constant of 1.5 min-1 at saturating concentrations of acetylene. If acetylene was added in the absence of O2, the cells remained active until O2 was re-introdu...
متن کاملThe Kinetics of Inactivation of Complement by Light
The photoinactivation of complement has been studied with a view to determining if possible how many kinds of molecules disappeared during the reaction. It was found that: 1. The apparent course of photoinactivation is that of a monomolecular reaction. 2. Diffusion is not the limiting factor responsible for this fact, because the temperature coefficient of diffusion is much higher than that of ...
متن کاملInactivation of yellow fever virus by glutaraldehyde.
The preservation of cellular ultrastructure by glutaraldehyde is well documented (D. D. Sabatini et al., J. Cell Biol. 17:19, 1963); however, we could find no report of its inactivation of the yellow fever virus in tissue. As laboratory infection of unvaccinated personnel by this virus is also well known (G. P. Berry and S. F. Kitchen, Am. J. Trop. Med. 11:365, 1931), it is important to ascerta...
