Rocky Mountain Wood Tick

Tick paralysis continues to be one of the most baffling and fascinating tickborne diseases in Canada. It was first reported in this country by Todd in 1912. Since then about 250 human cases, including 28 deaths, have been recorded from British Columbia. Outbreaks in cattle have affected up to 400 animals at a time, with losses in a herd as high as 65 head. Although the disease is most common in the Pacific northwest, where it is caused by the Rocky Mountain wood tick, Dermacentor andersoni Stiles, it has lately been reported as far south as Florida and has been produced by Dermacentor variabilis Say, Amblyomma maculatum Koch, and A. americanum (L.) (Gregson, 1953). The symptoms include a gradual ascending symmetrical flaccid paralysis. Apparently only man, sheep, cattle, dogs, and buffalo (one known instance) are susceptible, but even these may not necessarily be paralysed.

Rocky Mountain Spotted Fever

I would like to comment on the case of Rocky Mountain spotted fever with multiple coagulation disturbances reported by Atkins, et al. in Pediatrics, 36:327, 1965, and the letter concerning this case from Doctor Stryker in Pediatrics, 37:386, 1966. In our experience the association of thrombocytopenia with Rocky Mountain spotted fever (RMSF) is not uncommon. We have accumulated 19 cases of this infection associated with thromboctyopenia. After the preliminary report of this association appeared from this clinic, personal communication from other clinics in this and other regions brought to light the occurrence of other cases.
