Table 2. Comparison of the bbfA mutant with other reported biofilm reduced strains.

Mutant	Annotation	Source	Other phenotypes	Cell lines
wzn	ABC transporter	[9]	acapsular, ↓ oxidative survival, desiccation
fliC	Flagellin	[4]	aflagellate
cpdA	c-di-GMP phosphodiesterase	[11]	aflagellate, ↑ EPS†, autoagglutination	↓ A549 & THP1 invasion
pkk	polyphosphate kinase	[10]	aflagellate, ↓ oxidative survival
rpoE	Alternative sigma factor	[13]	↓ oxidative & osmotic survival	↓ J774 invasion
bspI	QS synthase 1	[12]	no QS 1
bspI3	QS synthase 3	[12]	no QS 3
bspR	QS regulator 1	[12]	no QS 1
bbfA	TAA	This study		wt A549 & J774 invasion

^†EPS =  exopolysaccharide.
