To gain further insight into the genetics of these species, we performed whole-genome sequence analysis of four strains: B. bronchialis AU3182, recovered from a CF patient in 2001; B. bronchialis AU17676, recovered from a CF patient in 2009; B. flabilis AU10664, recovered from a CF patient in 2006; and B. pseudohinzii HI4681, recovered in 2012 from bronchoalveolar lavage fluid of a C57BL/6 mouse homozygous for mutant cftr. Here, CFTR is linked to cystic fibrosis.
