  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Bacterium  \Bac*te"ri*um\,  n.;  pl  {Bacteria}.  [NL.,  fr  Gr  ?, 
  ?,  a  staff:  cf  F.  bact['e]rie.  ]  (Biol.) 
  A  microscopic  vegetable  organism,  belonging  to  the  class 
  Alg[ae],  usually  in  the  form  of  a  jointed  rodlike  filament, 
  and  found  in  putrefying  organic  infusions.  Bacteria  are 
  destitute  of  chlorophyll,  and  are  the  smallest  of  microscopic 
  organisms.  They  are  very  widely  diffused  in  nature,  and 
  multiply  with  marvelous  rapidity,  both  by  fission  and  by 
  spores.  Certain  species  are  active  agents  in  fermentation, 
  while  others  appear  to  be  the  cause  of  certain  infectious 
  diseases.  See  {Bacillus}.
