THE ACTINOMYCI-TKS. Vol. II 



the description is credited to a company and 

 not to an individual scientist. This was 

 done primarily as an effort to establish 

 priority for an antibiotic isolated from such 

 a culture, or for patent purposes. These 

 designations are placed in a separate cate- 

 gory, with emphasis on the antibiotic. A 

 group of cultures described by Gause et al. 

 (1957) has also been placed in a separate 

 category, since no decision can be reached 

 as yet concerning their synonymity with 

 previously described species. 



For more complete lists of names of 

 actinomycetes, comprising both genera and 

 species, the reader is referred to Buchanan 

 and Lessel (195!)), Lessel (1960), and es- 

 pecially to their forthcoming treatise "Index 

 Bergey an a." 



According to Buchanan and Lessel (1959), 

 there are now about 3000 names given to 

 different strains of bacteria that are recog- 

 nized as belonging to one or another of the 

 genera of the order Actinomycetales. They 

 emphasize, however, that "this is not to be 

 interpreted as meaning that there are three 

 thousand species, for a large proportion of the 

 names (probably two-thirds) are not available 

 for use because they were not validly pub- 

 lished, or are homonyms, or synonyms, or 

 are not binary combinations, or were pro- 

 posed as hypothetical names, or were in- 

 sufficiently described and are to be regarded 

 as naked names (nomina nuda) or as 

 doubtful names (nomina dubia) or are 

 officially rejected names, or because 

 illegitimate as contravening some other 

 Qomenclatural rule." 



An attempt has been made to present in 

 the following lists some of the incompletely 

 described forms of actinomycetes. Many 

 additional names are found in the previous 

 chapters as synonyms of well described 

 organisms. 



The first list comprises the forms described 

 under the names Actinomyces (.1), Str< />!<>- 

 thrix (St.), or Oospora (0). 



The name Actinomyces used in this list is 

 not to be confused with the genus Actino- 

 myces recognized at present, although some 

 of the cultures so designated here would no 

 doubt be considered as members of this 

 genus.
