I saw the comment in a Facebook group about Bartonella from the CEO of Galaxy Labs and wanted to share in case a scenario comes where an un-informed doctors says antibodies for bartonella are negative etc:

The challenge for host immune systems with Bartonella infection is actually immune evasion. Bartonella spp not only infect at low levels and grow slowly, but they are intracellular and hide inside cells. In fact, these bacteria can invade an unusually wide range of cell types, including red blood cells, brain cells, and stem cells.

This type of stealth invasion strategy means that Bartonella can evade antibody response and may result in a chronic intravascular bacteremia.

In severely immunocompromised people, like AIDS patients, Bartonella is also known to hide in bone and bone marrow and can trigger cellular proliferation and tumor growth. It’s not clear yet how often these more severe pathologies occur in people with healthier immune systems.

Intracellular infections pose a particular challenge for antimicrobial therapy, especially for Gram negative bacteria. I haven’t seen much work documenting the efficacy of specific herbal therapies for intracellular infection, especially in live models (in vivo) like mice or primates. Drug delivery is key for effective therapy.

Still herbal therapies can help a lot with reducing pathogen load, mitigating inflammation and supporting immune function. Still there are side effects that need to be considered.

Some individuals may have better tolerance than others or other issues that may interfere with therapeutic response. Best to work with an experienced clinician, I think.
