tory animals. Some were found to be 

 pathogenic to experimental animals. Mos1 

 of them were not tested, however, for their 

 pathogenicity. 



Organisms Belonging to the Genus Vo- 

 cardia 



In addition to many of the forms listed 

 previously, certain other incompletely de- 

 scribed forms which probably belong to the 

 genus Nocardia may be mentioned. These 

 have been described under the generic names 

 of Nocardia (X.), Asteroides (As.), and 

 Proactinomyces I Pr. >.

Various o1 her specific names for organisms 

 probably belonging to the genus Nocardia 

 have been listed under several other genera, 

 such as Cladothriz (CI. actinomyces Rossi- 

 Doria, 1891; Mace, 1897); Cohnistreptoihrix 

 I ( 'o. a/nericana Chalmers and ( ihristopherson, 

 1916); Discomyces (J). asteroides Eppinger, 

 L891; Godoelst, 1902); Flavobacterium (/•'. 

 salmonicolor den Dooren de Jong, 1927; 

 Bergey, 1930); Mycobacterium (M. albuvia- 

 lum Bergey, 1923); Serratia (S. corralina 

 Hefferan, 1904; Bergey, 192:!), and others. 

 Krassilnikov (1949) listed or described 

 numerous other forms belonging to this 

 genus under the names of Nocardia, Proac- 

 tinomyces, Mycobacterium, Bacillus, Bac- 

 terium, Brevistreptothrix, Cladothrix, Cohn- 

 istreptoihrix, Discomyces, and various others. 

 Thompson and Bissel (1957) suggested a 

 new generic name Polysepta. 



Descriptions Incomplete or Needed for 

 Actinomycetes Producing Specific 

 Antibiotics and Vitamins 



Because of the growing importance of 

 actinomycetes as producers of antibiotics 

 and because of the desire to claim priority 

 for a new antibiotic, many names have been 

 introduced for species of Streptomyces and 

 Nocardia. Often these names are mentioned, 

 with incomplete descriptions or with no 

 descriptions, in the patent literature or even 

 in trade journals. An attempt was made to 

 colled these. The list (Table 27) is far from 

 complete, however. 



A number of new species of actinomycetes 

 belonging to the genus Streptomyces have 

 been created by Cause et al. (1957-1959), 

 who justified this by the fact that there was 

 a great need for describing more organisms 

 capable of producing antibiotics. Only a 

 limited attempt was made in these descrip-
