Bartonella IgG

What Is Bartonella IgG?

Bartonella IgG refers to the presence of immunoglobulin G (IgG) antibodies in the bloodstream that are directed against Bartonella bacteria. These antibodies are produced by the immune system after exposure to the bacteria and play a key role in providing long-term immunity.

Understanding Bartonella Infections

Bartonella is a group of bacteria known to cause various infections in humans, including:

Cat scratch disease

Trench fever

Bartonellosis

These infections are commonly transmitted through bites or scratches from infected animals—particularly cats—or through contact with body lice or fleas.

Role of IgG Antibodies in Bartonella Diagnosis

IgG antibodies typically develop several weeks after an infection begins and can remain in the body for months or even years. A positive Bartonella IgG result indicates that the individual has been exposed to Bartonella in the past and that their immune system has developed a response.

When Bartonella IgG Testing Is Recommended

Ongoing or unexplained symptoms with a history of animal contact

Evaluation of past Bartonella exposure

Chronic symptoms that may be linked to a prior infection

Supporting diagnosis in cases where IgM is no longer detectable
