Monera
    n 1: prokaryotic bacteria and blue-green algae and various
         primitive pathogens; because of lack of consensus on how to
         divide the organisms into phyla informal names are used for
         the major divisions [syn: {Monera}, {kingdom Monera},
         {Prokayotae}, {kingdom Prokaryotae}]

   2. (Biol.) One of the five kingdoms of living organisms in

      as well as certain primitive pathogenic microbes, such as
      the Rickettsias.
