Aus der IUVA-Malayeri-2016-Fluence-Kompilation. Primärstudie: Craik et al. 2000 (Maus-Infektiositäts-Assay), LP-Hg 254 nm — etabliertes Modell für Giardia-Zysten; höhere Log-Reduktionen zeigen ausgeprägtes Tailing (resistente Subpopulation, 2-log erst bei ~28 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 4.5 mJ/cm²

D99 99 % 2-log 28 mJ/cm²

Morphology & UV-C resistance

Morphology class Protozoan cyst

Zyste mit Doppelmembran-Wand — UV-empfindlich, aber höhere Log-Reduktionen zeigen Tailing (resistente Subpopulation).
