  • a CF, infection of a CF patient; CF-e, strain that has spread epidemically among patients with CF; CGD, infection of a CGD patient; UK, United Kingdom; UTI, urinary tract infection.

  • b Strain types observed by RAPD and PFGE fingerprinting correlated for isolates examined in the panel; hence, each strain was given a single numerical strain type.

  • c Transformation rate per microgram of DNA electroporated into competent cells is the average number of Tpr colonies obtained from two independent experiments rounded up to the nearest log 10. Strains producing fewer than 100 Tpr colonies per electroporation were considered as having a negligible transformation rate.

  • d Strain type assigned for this study correlates to the numerical RAPD type assigned previously to this fingerprint pattern (19).

  • e Strains requiring selection on LB agar containing 400-μg/ml trimethoprim sulfate to overcome background due to intrinsic resistance; pUCP29T transformants from all other strains were selected on Luria-Bertani agar containing 100-μg/ml trimethoprim sulfate.
