确定寄生虫体内温度耐受性的任何尝试都将受到宿主温度耐受性的限制。大多数哺乳动物的体温范围很窄。冬眠的哺乳动物是一个明显的例外，它们的体温会发生剧烈的季节性变化。蝙蝠所能忍受的温度变化比其他冬眠动物要大，因为每当它们不活动时，它们的体温会下降到环境温度的几度之内。(Hock，1951年;莱曼和查特菲尔德，1955年）在这里报道的实验中，试图通过跟踪在不同温度下饲养的蝙蝠的实验感染过程来确定旋毛虫的温度耐受性。初步实验（Chute和Covalt，1958年）表明，寄生虫在34 ℃的蝙蝠肠道中会发育到成虫阶段，但在23 ℃或5 ℃的蝙蝠中不会。
Any attempt to determine the in vivo temperature tolerance of a parasite would be limited by the temperature tolerance of the host. Most mammalian species have a narrow body temperature range. Hibernating mammals provide a striking exception and undergo drastic seasonal variations in body temperature. The temperature variations tolerated by bats are greater than those of other hibernators, since their body temperature drops to within a few degrees of ambient temperature whenever they are inactive. (Hock, 1951; Lyman and Chatfield, 1955) In the experiments reported here, an attempt was made to define the temperature tolerance of Trichinella spiralis by following the course of experimental infections in bats held at different temperatures. Preliminary experiments (Chute and Covalt, 1958) indicated the parasite would develop to the adult stage in the intestines of bats held at 34 C, but not in bats at 23 C or 5 C.
