() Detection of donor silent pilin copies using the sequencing assay for strain FA1090 1-81-S2 grown for 22 h on solid media in the presence of IPTG. The parental copy sequence, , was retained in ∼97% of the templates in both assays, and the proportion of silent copy donors to the 3% of variant HV sequences is shown.
