STEC Center
The Thomas S. Whittam Shiga-toxin producing E. coli (STEC) Center was originally created by the late Tom Whittam to facilitate research on (STEC) and close relatives by providing a standard reference collection of well-characterized strains and on-line accessible databases. Currently, the Center does the following:
- Serves as a repository for the deposition of E. coli and other foodborne pathogens from human patients, animal reservoirs, and environments. The collection has over 16,000 bacterial strains.
- Distributes sets of strains for use by investigators. See the reference strains below for a list of the most commonly requested strains.
- Characterizes subsets of STEC using genetic markers of clonal identity and virulence genes (e.g., stx, eae).
STEC reference sets are available upon request
The reference sets indicated below represent the most commonly requested strains in the STEC Center collection; however, additional strains are available upon request. Strain requests can be sent to Shannon Manning at stec@cvm.msu.edu
In your request, please indicate which traits are of interest (e.g., stx profile, eae, O-type, etc.) and the number of strains you would like to receive. For non-profit organizations, the cost is $7.00/ strain, while for-profit organizations pay $120/strain plus shipping charges. Please note that an MTA is required to be completed prior to shipment and that STEC cannot be exported outside the U.S.
