Comparison of diagnostics by IFA, FISH and Microscopy for babesiosis with qPCR using molecular beacon probes for BmTPK in human blood samples. For all patients samples, qPCR was repeated three times and results of each repeat are marked by ‘+’ or ‘–’ sign. Thus, +/+/+ indicates that qPCR was positive in all three repeats of the qPCR for an individual sample. There is a high correlation between all three tests when samples were negative by qPCR. Higher sensitivity of detection of B. microti by qPCR is demonstrated by a significant number of positive samples that were diagnosed negative for babesiosis by Indirect IFA, FISH and microscopic examination of Giemsa-stained blood smears.
