\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.
