a
MID expression was defined by flow cytometry. Bacteria were incubated with a human IgD(κ) myeloma protein followed by incubation with a secondary FITC-conjugated pAb and subsequent flow cytometry analyses.
b
Number of isolates with the indicated percentage of IgD-binding bacteria in high-intensity peak (percentage of total).
