1 Investigation of suspected laboratory cross-contamination: interpretation of single smear-negative, positive cultures for Mycobacterium tuberculosis  V.J. Cook, G. Stark, D.L. Roscoe, A. Kwong, R.K. Elwood  Clinical Microbiology and Infection  Volume 12, Issue 10, Pages (October 2006) DOI: /j x Copyright © 2006 European Society of Clinical Infectious Diseases Terms and Conditions

2 Fig. 1 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).
