Opinion 11. 



1. Shigella dysenteriae (Shiga) Castellani and Chalmers 1919 was validly 



published and is legitimate as the name of the dysentery bacterium de- 

 scribed by Shiga (1898). 



2. The specific epithet flexneri in the species name Shigella flexneri Castellani 

 and Chalmers 1919 is designated as a conserved specific epithet (epitheton 

 specificum conservondum) for the species first described as Bacillus dysen- 

 teriae Flexner 1900. 



3. The species name Shigella boydii Ewing 1949 was validly published and 

 is legitimate. The specific epithet boydii in the species name Shigella 

 boydii is to be conserved (epitheton specificum conservondum). 



4. The species name Shigella sonnei (Levine) Weldin 1927 was validly pub- 

 lished and is legitimate. The specific epithet sonnei in the species name 

 Shigella sonnei is to be conserved (epitheton specificum conservondum). 



5. A type or standard culture is to be designated by the Enterobacteriaceae 

 Subcommittee of the International Committee on Bacteriological Nomen- 

 clature for each of the four species. Such cultures as far as possible shall 

 be maintained in each of the national Type Culture Collections and in the 

 International Shigella Center, Chamblee, Georgia, U. S. A. 



6. A culture belonging to the species Shigella flexneri, S. boydii or S. sonnei 



could be completely identified by appending to the name "serotype " 



(with the appropriate designation).
