Pyrogenic responses of the pika, Ochotona rufescens rufescens.
In 3-month-old male and female pikas, Ochotona rufescens rufescens, reared at an ambient temperature of 25 degrees C, the mean within-day body temperature was 39.2 degrees C without significant variance. At an ambient temperature of 35 degrees C it increased markedly in males while decreased slightly at 5 degrees C. The pikas showed lower sensitivity than Japanese white rabbits to a pyrogenic E. coli endotoxin.
