Aus der IUVA-Malayeri-2016-Fluence-Kompilation. Primärstudie: Ware et al. 2010 (Maus-Infektiositäts-Assay, SCID-Mäuse), LP-Hg 254 nm — Oozysten; wichtiger wasser- und lebensmittelbedingter Parasit (Katzen-Endwirt, Toxoplasmose). Dumètre et al. 2008 (IFA-Assay): 7.2 mJ/cm2.

UV-C dose–response (D-values)

A D-value is the UV-C dose (in mJ/cm²) needed for a given log-reduction. D90 = 90 % inactivation = 1-log; D99 = 99 % = 2-log; D99.9 = 99.9 % = 3-log, and so on. Values come from the cited study under its specific test conditions.

Reduction log Dose (mJ/cm²)

D90 90 % 1-log 3.4 mJ/cm²

D99 99 % 2-log 6.8 mJ/cm²

Morphology & UV-C resistance

Morphology class Protozoan cyst

Oozyste mit mehrschichtiger Wand — mässig UV-empfindlich; chlorresistent.
