The involvement of porcupines, Erethizon dorsatum (L.), in the ecology of Colorado tick fever (CTF) virus in Rocky Mountain National Park was investigated from 1975 to 1977. Porcupine dens and feeding activity were found mostly on rocky knolls or on south-facing slopes within open stands of the montane coniferous forest, and 20 adult porcupines were trapped or captured by hand at those locations. An average of 24.6 +/- 5.4 adult Dermacentor andersoni Stiles ticks were found per animal (annual range, 17.5-31.4 ticks). The minimum CTF virus infection rate of the ticks removed from porcupines varied from 129 to 257, whereas for questing adult D. andersoni ticks from the same geographic area was 205 in 1976. No virus was isolated from the 20 animals, but 85% had neutralizing antibody against CTF virus. Porcupines utilize the same habitats described for the CTF ecosystem in Rocky Mountain National Park and appear to be an important host for adult D. andersoni.
1975年至1977年期间，对豪猪（Erethizon dorsatum (L.)）在落基山国家公园科罗拉多蜱传热（CTF）病毒生态中的作用进行了调查。豪猪的洞穴和觅食活动大多位于山地针叶林开阔林分内的岩石小山上或朝南的山坡上，在这些地点手工诱捕或捕获了20只成年豪猪。每只动物平均发现24.6±5.4只成年安德逊革蜱（Dermacentor andersoni Stiles）（年度范围为17.5 - 31.4只蜱）。从豪猪身上采集的蜱的CTF病毒最低感染率在129至257之间，而同一地理区域内正在觅食的成年安德逊革蜱在1976年的感染率为205。从这20只动物身上未分离到病毒，但85%的动物具有抗CTF病毒的中和抗体。豪猪利用落基山国家公园CTF生态系统中描述的相同栖息地，似乎是成年安德逊革蜱的重要宿主。
