What is Ehrlichia chaffeensis IgG?
What is Ehrlichia chaffeensis IgG?
Ehrlichia chaffeensis (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.
Is Ehrlichia chaffeensis Gram positive or negative?
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.
How do you get Ehrlichia chaffeensis?
Ehrlichiosis home These bacteria are spread to people primarily through the bite of infected ticks including the lone star tick (Amblyomma americanum) and the blacklegged tick (Ixodes scapularis). People with ehrlichiosis will often have fever, chills, headache, muscle aches, and sometimes upset stomach.
Is Ehrlichia chaffeensis Lyme disease?
Human Monocytic Ehrlichiosis (HME) , is caused by Ehrlichia chaffeensis, a type of bacteria known as rickettsia, and is transmitted to humans by the bite of the lone star tick Amblyomma americanum. Unlike Lyme disease, ehrlichiosis is considered an acute infection without chronic long-term consequences.
What are the symptoms of ehrlichiosis?

What is human monocytic ehrlichiosis?
Human Monocytic Ehrlichiosis (HME) is a rare infectious disease belonging to a group of diseases known as the Human Ehrlichioses. These diseases are caused by bacteria belonging to the “Ehrlichia” family.
What does Ehrlichia chaffeensis cause?
Ehrlichia chaffeensis Infection Ehrlichia chaffeensis causes human monocytic ehrlichiosis in North America, an emerging disease that is characterized in human patients by fever, headache, myalgia, thrombocytopenia and leukopenia, and elevations in hepatic transaminases.
What type of cell does Ehrlichia chaffeensis infect in humans?
chaffeensis infects predominantly mononuclear phagocytic cells. The most frequently infected blood cells are monocytes; however, infections in other cell types have been described, including lymphocytes, atypical lymphocytes, promyelocytes, metamyelocytes, and band and segmented neutrophils (1, 91, 174, 209).
What disease does Ehrlichia chaffeensis cause?
The bacterium, named “Ehrlichia chaffeensis” after the army base where the soldier was stationed (Fort Chaffee, Arkansas), is the cause of Human Monocytic Ehrlichiosis (HME). From 1986 to 1997, 742 cases of HME were reported to the CDC.
Is ehrlichiosis serious?
Without prompt treatment, ehrlichiosis and anaplasmosis can have serious effects on an otherwise healthy adult or child. People with weakened immune systems are at a higher risk of more-serious and life-threatening complications. Complications of an untreated infection may include: Kidney failure.
