The B. cenocepacia recA lineage IIIB isolates identified as ST-122 (Table) include the PHDC strains, predominant in US CF patients (AU1054) and previously found in US soil (HI-2424) (10), and CEP0497, which was obtained from a leg wound in a non-CF patient in Canada. Here, RAD51 is linked to cystic fibrosis.
