Experiments are reported concerning the influence of low ambient temperatures on mice which have been challenged with K. pneumoniae. The metabolic behavior and virulence of the organisms isolated from mice maintained at 2 or 21 C were investigated. The oxygen uptake of the organisms appeared to be directly proportional to the temperature of incubation. The growth ability of K. pneumoniae isolated from micemaintained at 2 C appeared to be temperature independent between 37 and 32 C, whereas the K. pneumoniae isolated from mice maintained at 21 C exhibited growth curves that were temperature dependent. The virulence of the K. pneumoniae isolated from mice maintained at 2 or 21 C did not appear altered.
