I had a chance to look at some of my old issues of IJSB and yes in fact 
Yersinina pestis and Yersinia psedotuberculosis are related taxonomically and 
the former is in fact a subspecies of the latter.  However, due to the 
potential "serious consequences for human welfare and health" the name 
Yersinia pseudotuberculosis subsp. pestis was rejected and this bacterium was 
name Yersinia pestis.

The reference for this is:

Opinion 60 : Rejection of the Name Yersinia psedutuberculosis subsp. pestis 
(van Loghem) Bercovier et al. 1981 and Conservation of the Name Yersinia 
pestis (Lehmann and Neumann) van Loghem 1944 for the Plague Bacillus. 1985.  
International Journal of Systematic Bacteriology (IJSB) Vol. 35:p. 540.

Nice to know that even at my age, the memory still works :-).

Thank you again
