Biological Hazards
Published in W. David Yates, Safety Professional’s Reference and Study Guide, 2020
Rocky Mountain spotted fever is the most severe tick-borne rickettsial illness in the United States. Occupations at greatest risk include military personnel, foresters, rangers, ranchers, farmers, trappers, construction workers, and lumber workers. This disease is caused by infection with the bacterial organism Rickettsia rickettsii. The organism that causes Rocky Mountain spotted fever is transmitted by the bite of an infected tick. The American dog tick (Dermacentor variabilis) and Rocky Mountain wood tick (Dermacentor andersoni) are the primary arthropods (vectors) that transmit Rocky Mountain spotted fever bacteria in the United States. The brown dog tick Rhipicephalus sanguineus has also been implicated as a vector as well as the tick Amblyomma cajennense in countries south of the United States.14

The species Rhipicephalus sanguineus s. l. mainly afflicts dogs, but it can also parasitize other domestic animals and even humans (Gray et al. 2013). This species has great medical and veterinary importance since it is a vector of various pathogens (Rickettsia rickettsii, R. conorii, Ehrlichia canis, and Babesia vogeli) that cause diseases in dogs and humans, posing severe risks to animal welfare and public health (Dantas-Torres et al. 2018).
