Earlier I had mentioned testing for erlichiosis and a maybe for Lyme. While I was sure that the Igenex tests pointed to something, I was unsure whether the ricksettal organism they found was actually what was reported.
While Erlichiosis is associated with malaise, weakness, fever, etc. I had yet to find any article pointing to its role in our symptoms. However the article below indicates an instance where the Erlichiae could be a cofactor in hemophagocytotic syndromes causing a lymphatic infiltrate. The article also mentions "murine tyhpus", which I though also could be a cofactor along with Parvo and EBV with immune disregulation.
Anyway, here's the article about erlichiosis:
