Full Description

Because the standard method of determining Giardia inactivation in disinfection tests--which involves counting dead and living organisms--can be extremely tedious, an alternative method, whereby the concentration of only viable trophozoites is estimated, is being sought. This article describes the development of such a volumetric method and its verification by comparing the results obtained with the standard and volumetric methods. This work demonstrates that the two methods yield equivalent results--at least for the disinfectants and waters examined. Whether this equivalence operates for larger-scale concentration techniques and for different waters, disinfectants, and organisms remains open to further research. Includes 13 references, tables, figures.
