1 ILLUMINA (Illumina MiSeq) run: 486,091 spots, 243M bases, 156.3Mb downloads

Design: Illumina libraries were prepared for all strains using the KAPA Low-Throughput Library Preparation Kit with Standard PCR Amplification Module (Kapa Biosystems, Wilmington, MA), following manufacturer's instructions except for the following changes: 750 ng DNA was sheared at 30 psi for 40 s and size selected to 700-770 bp following Illumina protocols. Standard desalting TruSeq LT and PCR Primers were ordered from Integrated DNA Technologies (Coralville, IA) and used at 0.375 and 0.5 M final concentrations, respectively. PCR was reduced to 3-5 cycles. Libraries were quantified using the KAPA Library Quantification Kit (Kapa), except with 10 l volume and 90-s annealing/extension PCR, then pooled and normalized to 4 nM. Pooled libraries were requantified by ddPCR on a QX200 system (Bio-Rad), using the Illumina TruSeq ddPCR Library Quantification Kit and following manufacturer's protocols, except with an extended 2-min annealing/extension time. The libraries were sequenced 2 250 bp paired end v2 on a MiSeq instrument (Illumina) at 13.5 pM, following manufacturer's protocols.

The rise in foodborne-related outbreaks of non O157 shiga-toxin producing E. coli (STECs) emphasizes the importance of developing improved methods to rapidly detect and characterize STECs. The major serovars of STEC associated with illness have been O26, O111, O103, O121, O45, and O145, accounting for 25-50% of human illness caused by STECs and, in some cases, severe illness comparable to illness caused by E. coli O157:H7. Sequencing of STECs from the agriculturally important region of the California central coast will address the diversity of genomic content and physiology of STECs compared to E. coli O157.
