The ATCC in Rockville (MD) distributes both the ECOR and SARA 
collections. However, this is _very_ expensive (e.g. 72 * 90 US$ for the 
complete ECOR collection sent to the U.K. = almost US$ 6500!) A very 
useful collection, SARB, with a few representative strains of the SARA 
collection, as well as a collection of other medically important serovars 
of Salmonella is available from the Salmonella Genetic Stock Centre 
(there is a webpage at: www.ucalgary.ca/~kesander), Dr. Sanderson, in 
Calgary, Alberta. For other species and genera of Enterobacteriaceae, 
everything depends on what kind of strains you are looking for. If it is 
'international reference strains' you will have to contact strain 
collection centres (NCTC, London, or ATCC &c.). The CCUG, University of 
Gothenburg, Sweden (also on the web, I believe) provides excellent 
services with reasonable prices. Clinical microbiology colleagues may 
help you out with fresh clinical isolates (we certainly would), however, 
availability of the more 'exotic' species and number of strains are 
usually limited.
