OPINION 8 



The Correct Species Name of the Streptococcus 

 of Bovine Mastitis 



Haupt (1952) proposed that the name of the streptococcus of bovine 

 mastitis be accepted as Streptococcus agalactiae Kitt, although the 

 binomial given by Kitt was Streptococcus agalactiae contagiosae. Han- 

 sen (1953) suggested that Kitt's single specific epithet of two words 

 was changed by Lehmann and Neumann (1896) to a single word, 

 and that the species name Streptococcus agalactiae Lehmann and 

 Neumann has become generally recognized and is in common use. A 

 poll of those working with the bovine mastitis streptococci showed 

 general agreement that confusion would best be obviated by conser- 

 vation of the Lehmann and Neumann species name against all syno- 

 nyms having priority. The Judicial Commission, in its meeting of 

 5 September, 1953, approved in principle the conservation of the 

 species name Streptococcus agalactiae Lehmann and Neumann, but 

 with instructions to the Editorial Board to discuss certain matters 

 with the proponents of the conservation. It is recognized that 

 the description of the characteristics of the species as given by 

 Lehmann and Neumann are probably inaccurate in some particulars 

 and differ from the descriptions of earlier writers. It is proposed 

 that a type culture or standard culture of Streptococcus agalactiae 

 Lehmann and Neumann be selected by a committee of experts, ap- 

 proved, and adequately described, and that the species be based upon 

 this type culture rather than on the Lehmann and Neumann de- 

 scriptions. 



Opinion 8. 



The species name Streptococcus agalactiae Lehmann and Neumann 1896 is 

 conserved against all synonyms having priority.
