Lyme Disease Ehrlichia chaffeensis Tick-Borne Infection (IgG, IgM)
Human Monocytic Ehrlichiosis (HME) is a tick-borne infection caused by Ehrlichia chaffeensis. Infections range in severity from asymptomatic to life-threatening, especially in patients who are immunocompromised.
Ehrlichia chaffeensis is an obligate intracellular, Gram-negative species of Rickettsiales bacteria. It is a zoonotic pathogen transmitted to humans by the lone star tick (Amblyomma americanum). It is the causative agent of human monocytic ehrlichiosis.
In general, Tick bites are known to cause Lyme disease, but they can also transmit a condition called ehrlichiosis. Ehrlichiosis is a bacterial illness that causes flu-like symptoms that include fever and aches. It can cause very serious complications if left untreated.
