| ecology of porcupines (erethizon dorsatum) and colorado tick fever virus in rocky mountain national park, 1975-1977. | 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 ra ... | 1993 | 8433332 |

| survey for evidence of colorado tick fever virus outside of the known endemic area in california. | a virus very similar or identical to colorado tick fever (ctf) virus was recovered from the blood clot of one of 104 black-tailed jack rabbits (lepus californicus) examined during a survey for various zoonotic agents in mammals and ticks from the university of california, hopland field station, mendocino county, california, 1974--79. this is the first reported isolation of a ctf-like virus from l. californicus, and only the second time such a virus has been found in northwestern california. mend ... | 1982 | 7102919 |

| case report: a case of colorado tick fever acquired in southwestern saskatchewan. | colorado tick fever virus is transmitted by dermacentor andersoni ticks. in canada, these ticks are found in the southern regions of british columbia (rocky mountains) and alberta, as well as southwestern saskatchewan. colorado tick fever should be clinically suspected in patients presenting with a biphasic febrile illness and leukopenia following tick exposure in the appropriate geographic area. | 2018 | 29363458 |
| detection of colorado tick fever virus by using reverse transcriptase pcr and application of the technique in laboratory diagnosis. | colorado tick fever (ctf) virus elicits an acute illness in humans, producing nonspecific flu-like symptoms and a biphasic fever in approximately 50% of patients. the disease is transmitted by the adult rocky mountain wood tick (dermacentor andersoni), and therefore incidence is limited by the habitat and life cycle of that vector. the early symptoms of infection are difficult to distinguish from those of several other agents, especially rickettsia rickettsii. serologic testing is usually unable ... | 1997 | 9114408 |

| infection with colorado tick fever virus among humans and ticks in a national park and forest, wyoming, 2010. | colorado tick fever (ctf) is an underreported tick-borne viral disease occurring in the western united states. ctf illness includes fever, headache, and severe myalgia lasting for weeks. wyoming has one of the highest ctf incidence rates with approximately 30% of infected persons reporting tick exposure in a wyoming national park or forest before symptom onset. we assessed ctf virus infections among humans and dermacentor andersoni ticks in grand teton national park (grte) and bridger-teton nati ... | 2014 | 25229706 |
| prevalence and strains of colorado tick fever virus in rocky mountain wood ticks in the bitterroot valley, montana. | the rocky mountain wood tick, dermacentor andersoni, has long been known to transmit human pathogens. within the bitterroot valley, ravalli county, montana, these agents include rickettsia rickettsii, francisella tularensis, and colorado tick fever virus (ctfv). found in the western united states where wood ticks occur, ctfv causes a biphasic, febrile illness in humans and persists in enzootic cycles involving the ticks and small mammals. ctfv belongs to the genus coltivirus, family reoviridae, ... | 2019 | 30939106 |
