Table 2. Adhesion of different A. hydrophila serotype O34 strains to HEp-2 cells.

Strain and main characteristics	Mean n°. of bacteria/ HEp-2 cell +/- SD	% Reduction in adhesion ^a
AH-3; wild type	18.3 +/- 2.2
AH-405; AH-3 rifampicin-resistant mutant	17.9 +/- 2.0	2 ^b
AH-3Δ wecP	7.2 +/- 0.7	61
AH-3Δ wecP + pBAD33	6.9 +/- 1.0	62
AH-3Δ wecP + pBAD-WecP_Ah	17.7 +/- 2.1	3
AH-3Δ wecP + pBAD33-WecA_Ec	12.7 +/- 1.4	30
AH-3Δ wecP + pBAD-WecA-WzyE_Ec	18.0 +/- 2.5	1
AH-3Δ wecP + pBAD-WzyE_Ec	6.7 +/- 0.5	63

^a The level of adhesion of strain AH-3 was used as 100% value.

^b Student’s t test, P, 0.001.

The strains carrying pBAD plasmids were grown under inducing conditions (+ arabinose)
