Potential laboratory cross-contamination dates for identified contaminant source cases, with pseudo-clusters confirmed by restriction fragment length polymorphism analysis. Cases identified initially as probable cases of contamination are identified by triangles, and those identified as clinically active cases are identified by circles. Source cases are identified by squares, with the number inside the square representing the number of matching bands; * signifies one extra band (though subsequently matched by multiple interspersed repetitive units variable tandom repeats analysis).
