Abstract:
:A new microplate assay for the determination of activity in vitro against Giardia intestinalis has been developed in which viability is measured by soluble formazan production from a tetrazolium reagent. Metabolic reduction of the latter gives rise to a coloured product which may be determined directly by optical density measurement. Using this method the anti-giardial activities of more than 20 anti-microbial compounds have been assessed. The results obtained with a number of known anti-giardial agents, including metronidazole (50% inhibitory concentration [IC50] = 2.98 microM) and furazolidone (IC50 = 4.14 microM), compare well with previously published data; mepacrine, however, was found to produce a biphasic dose-response curve from which two IC50 values (0.816 and 6.83 microM) were obtained. This method provides a convenient means by which the search for new anti-giardial agents may be facilitated.
