A disease caused by the bite of a tick that is hosting a rickettsia characterized by chills, fever, pains in muscles and joints, and a reddish purple skin eruption.
A type of typhus caused by Rickettsia rickettsii, transmitted to humans by ticks.
An infection in humans that is transmitted by microscopic parasites called Rickettsiae; also known as tick fever. Wood or dog ticks are the vector of infection, transmitting the disease from rodents to humans. Rickettsia rickettsii, the bacteria that cause Rocky Mountain spotted fever, attack the endothelium (cells that line the walls of small blood vessels). Within 1 to 2 days of being bitten by an infected tick, a person may experience a loss of appetite and general malaise, followed by headache, chills, muscle and joint pain, light sensitivity, and pain at the back of the eyes.
A fever of the typhus group. It received its name from the fact that it was first reported in the Rocky Mountain States of the United States; these are still the most heavily infected areas, but the fever is now found in all parts of the US. The causative organism is Rickettsia rickettsi, which is transmitted to humans by tics.
An infectious disease caused by the bacterium Rickettsia ricketsii and transmitted by the wood tick Dermacentor andersoni or D. variabilis. Originally thought to exist only in the western U.S., it can occur anywhere that the tick vector is present.
An uncommon infectious illness characterized by a fever and a spotty rash that expands across the body, becomes darker, grows in size, and may bleed.
Rocky Mountain spotted fever is prevalent in both North and South America and is triggered by a type of microbe known as rickettsia. This organism is transferred from small mammals to humans through the bite of a tick. The condition is typically treated using chloramphenicol or tetracycline.
