Protomyxzoa Rheumatica (the fry bug, FL1953, or hemabartonella are other names it has had over the years). It's transmitted by ticks, fleas and mosquitoes and is becoming a commonly found co-infection. This is not an antibody test but an actual blood stain/smear, visualizing this protozoa. There is also a biofilm stain/slide - allowing visualization of the biofilm communities in the blood. www.frylabs.com
