Rickettsia Rickettsii
Rickettsia rickettsii is a type of bacteria that causes Rocky Mountain spotted fever, a serious illness transmitted primarily by ticks. This bacterium infects the cells lining blood vessels, leading to inflammation and damage, which can result in symptoms such as fever, rash, and muscle pain.
The primary vectors for Rickettsia rickettsii are American dog ticks and wood ticks. Infection can occur when a tick bites and feeds on a host, typically humans or animals. Early diagnosis and treatment with antibiotics are crucial for recovery, as severe cases can lead to complications or even death.
