A patient with documented chronic Lyme disease had further testing for Bartonella.
A test performed at Fry labs reported abnormally shaped red blood cells without bacteria.
A wet mount at Clongen showed scarce round motile bacteria.
A PCR at Clongen for "Bartonella species," was positive.
In general, PCR testing for Bartonella is not performed because of a low yield.
These results, albeit in a single patient, suggest that: 1) wet mount exams may be more accurate than stained whole blood samples for the identification of these bacteria and 2) these small round organisms seen in patient's blood do in fact suggest ongoing infection with Bartonella species.
