We investigated cryopreservation of horizontal transmission stages of Holospora undulata, a micronucleus-specific bacterial parasite of Paramecium caudatum. Unlike in previous studies on related Holospora species, protocols using glycerol as cryoprotectant failed entirely. In contrast, freezing with dimethyl sulfoxide (Me2SO) conserved infectiousness of nearly all replicate inocula, although infection success was considerably lower than that of fresh inocula. Infection probability was enhanced by increasing the Me2SO concentration from 5 to 10%, and by freezing at -196 degrees C rather than -80 degrees C. Prolonged storage of up to 3 months had no significant effect on the viability of the inocula.
