Temperature directly affected the in vivo and in vitro multiplication of Trypanosoma danilewskyi Laveran et Mesnil. The parasitemia in experimentally infected goldfish (Carassius auratus L.) increased rapidly at 20 degrees C and reached its peak in 3 to 5 weeks post-infection. The multiplication was slower at 10 degrees C. The parasitemia declined after the peak at 20 degrees C. Lowering of temperature of the infected goldfish from 20 degrees C to 10 degrees C slowed multiplication of the parasite. Similarly, raising of temperature of infected fish from 10 degrees C to 20 degrees C resulted in rapid multiplication of the parasite. These were confirmed in the in vitro studies. It is suggested that lower temperature slows the multiplication of the parasites because T. danilewskyi is a parasite of a warm water host (Carassius auratus gibelio Bloch).
温度直接影响达尼列夫斯基锥虫（Laveran et Mesnil）在体内和体外的繁殖。在实验感染的金鱼（Carassius auratus L.）中，寄生虫血症在20℃时迅速增加，并在感染后3至5周达到峰值。在10℃时繁殖较慢。20℃达到峰值后寄生虫血症下降。将感染金鱼的温度从20℃降至10℃会减缓寄生虫的繁殖。同样，将感染鱼的温度从10℃升至20℃会导致寄生虫迅速繁殖。这些在体外研究中得到了证实。有人认为，较低的温度会减缓寄生虫的繁殖，因为达尼列夫斯基锥虫是温水宿主（银鲫，Carassius auratus gibelio Bloch）的寄生虫。
