There were errors in Table 1 in the original article. The reference numbers in the last column in Table 1 were incorrect. The correct reference numbers are shown in the Table below. Please refer to the original article for the corresponding reference details. Also, the entries in rows 14–17 of the “Topography motifs” column, in rows 3–5 and 14 of the “Topography material” column, in rows 5 and 7–13 of the “Topography dimensions” column, and in rows 5 and 10–13 of the “BFR or BFR_like” column in Table 1 were incorrect. The correct entries are shown in the Table below.

Table 1 Bacteria adhesion as related to substrate topography: interactions between bacteria species and fibrous and fibrous-like topography motifs expressed through the bacteria-to-fibre or bacteria-to-fibre-like ratio (BFR or BFR_like) (see the text [in the main article] for more details) obtained from some publications (Ref. column)

Bacteria	Topography motifs	Topography material	Topography dimensions^a	Bacteria dimensions	BFR or BFRlike	Notes	Ref.
a Dimensions of the pristine materials, i.e. ignoring the possible variations due to the presence of coating conditioning films. b BFRlike values.
Burkholderia terricola	Fibres	Polycaprolactone	20–180 nm diameter (coated fibres), 10–129 nm diameter (pristine fibres)	0.5 μm diam., 1.5 μm length	50–3.88 diameter (measured in pristine fibres), 22.7–1.67 (measured in coated fibres), 25–2.78 (measured in bacteria-binding fibres)	Always BFR > 1.

Escherichia coli	Fibres	Polystyrene	300–3000 nm diameter	0.5 μm diam., 2 μm length	1.7–0.17	Prevalent colonisation, when BFR = 1. BFR < 1: cells aligned along single fibres in a train-like shape, BFR ≤ 1: cells maintained the original rod-like shape and formed clusters in the fibrous weave, BFR > 1 cells distorted and wrapped around the fibres	32

Pseudomonas aeruginosa	Fibres	Polystyrene	70–1100 nm diameter	0.5 μm diam., 1.8 μm length	7.1–0.45	Prevalent colonisation in the interfibre spacing, BFR < 1: greater cell accumulation. BFR > 1: lower colonisation. BFR = 1: intermediate adhesion	12

Shewanella oneidensis	Wires	Si	300 nm diameter, 3 μm height	0.6 μm diameter; 2.5 μm length	2^b	Bacteria preferred to stay on the nanowires rather than travel through the planar substrate, expressing a distinct interaction with the nanowires	83
