Psychrosensitive

[A]ttenuated strains of myxoma virus, like attenuated strains of poliovirus type I, are less thermoresistant and less psychrosensitive (in their replication) than virulent strains.

The experimental results described above, considered with those reported elsewhere, are compatible with the hypothesis that T-antigen, upon reaching a critical concentration, triggers a psychrosensitive (cold-sensitive) event(s) which leads to the activation of the cellular DNA-synthesizing apparatus and, as a consequence, to the replication of the host cell chromosomes.

The sequence of events of the lytic infection is essentially the same at 27°C as during infection at 37°C. However, due to a cold-sensitive metabolic process ("psychrosensitive event") that is intercalated between the appearance of T antigen and virus-induced chromatin replication, the time course of infection is considerably slower at 27°C[…].

[B]acterial taxa which we identified as psychrosensitive were inhibited, whereas taxa identified as psychrophilic flourished.
