Paramecium  or Paramoecium  is a genus of unicellar citiated protozoa. They are characterised by the presence of thousands of cilia covering their body. Paramecium were among the first cillates to be seen by microscopists, in the late 17th century. They were probably known to the dutch pioneer of protozoology, Antoine Van Leeuwenhoek, and were clearly described by his contemporary.

Paramecium live in aquatic environments, usually in stagnant, warm water. The species Paramecium bursaria forms symbiotic relationships with green algae. The algae live in it's cytoplasma. Algal photosynthesis provides food source for Paramecium. Some species form relationships with bacteria. Species of Paramecium range in size from 50 to 330 micrometers in length. Cells are typically ovoid, elongate, foot - or cigar - shaped.

Paramecium can have both positive and negative effects on humans. Paramecium have potential to spread harmful diseases in the human body by imbalance, but they can also serve a benefit to humans by destroying cryptococcus neoformans, a type of disease caused by special fungi ( from the genus cryptococcus ) that can spread in the human body and and affect the immune system.
