Kappa organism : ウィキペディア英語版 | Kappa organism In biology, Kappa organism or Kappa particle refers to inheritable cytoplasmic symbionts, occurring in some strains of Paramecium. Paramecium strains possessing the particles ("Killers") liberate into the culture medium a substance lethal to Paramecium not containing kappa particles. Kappa particles are Feulgen-positive and stain with Giemsa after acid hydrolysis. The length of the particles is 0.2–0.5μ. The particles are considered to be intracellular symbionts, occupying a position between viruses, bacteria, and organelles,〔(Kappa Particles ) in mediLexicon〕 mere nucleoprotein〔(Kappa Particles ) in McGraw-Hill Science & Technology Dictionary〕 or, by another sources bacterium Caenobacter taenospiralis. == References ==
