Results with Flagellate B 



The organism used in this test, designated as Flagellate B, is 

 an active inhabitant of the soil, in which it occurs in numbers 

 nearly as great as the three preceding flagellates. This organism 

 does not appear to affect the number of bacteria, as determined 

 by the plate culture method, either in soil nor in soil extract 

 cultures.
