Analysis of Salmonella strains with ELISA-like tailspike adsorption (ELITA) assay using Strep-tag®II-labelled 9NATSP as a probe. One sample shows strain DB7136 incubated with 9NATSP wild type prior to ELITA (red bar). Strain E. coli HTD2158 [38] and bovine serum albumin (BSA) were used as a negative control. Numbers refer to the Wernigerode collection (cf. Table 3). Error bars represent standard deviation from four replicate experiments
