The sdeK mutant rescues a csgA mutant in codevelopment assays^a

Strain(s) plated for development	Total no. of viable spores/mlb	No. of viable csgA741 spores/ml
Wild type	1.5 × 108	NAc
csgA741	3.2 × 104	3.2 × 104
ΔsdeK1	4.0 × 103	NA
Wild type + csgA741 (1:1)	9.4 × 107	5.8 × 107
ΔsdeK1 + csgA741 (1:1)	1.1 × 108	1.1 × 108

^aSpores were collected after 3 days of codevelopment as described in Materials and Methods. Spores were plated on CTT, and germinated cells were patched onto CTT plates containing kanamycin to determine strain derivation, as described in Materials and Methods. 

^bStandard deviations were between 15 and 23%.
