Pseudobacteria \Pseu`do*bac*te"ri*a\, n. pl. [Pseudo- +
   bacteria.] (Biol.)
   Microscopic organic particles, molecular granules, powdered
   inorganic substances, etc., which in form, size, and grouping
   resemble bacteria.

   Note: The globules which divide and develop in form of chains
         are organized beings; when this does not occur, we are
         dealing with pseudobacteria. --Sternberg.
