Comparison of cell enumeration by flow cytometry and the Petroff-Hausser counting chamber. B. burgdorferi bacteria were collected by centrifugation, suspended in motility buffer, and serially diluted. Cell concentrations were determined manually with a Petroff-Hausser counting chamber (squares, solid line) or by flow cytometric analysis (circles, dashed line). The coefficient of correlation between the two methods was >0.98.
