Mycoplasma agassizii

Mycoplasma agassizii is a species of bacteria in the genus Mycoplasma. This genus of bacteria lacks a cell wall around their cell membrane.[1] Without a cell wall, they are unaffected by many common antibiotics such as penicillin or other beta-lactam antibiotics that target cell wall synthesis. Mycoplasma are the smallest bacterial cells yet discovered,[2] can survive without oxygen and are typically about 0.1 µm in diameter.

This mycoplasma species was originally isolated from a species of desert tortoise Gopherus agassizii which was named for by Louis Agassiz.[3][4]

Since its discovery, it has been recovered from other species of tortoises:

  • Geochelone chilensis or Chaco tortoise
  • Geochelone pardalis or Leopard tortoise
  • Geochelone elegans or Indian star tortoise
  • Geochelone forstenii or Travancore tortoise
  • Geochelone sulcate or African spurred tortoise
  • Gopherus agassizii or desert tortoise
  • Gopherus polyphemus or Gopher tortoise
  • Indotestudo species
  • Terrapene carolina bauri or Florida box turtle
  • Testudo graeca graeca or Spur-thighed tortoise
  • Testudo graeca ibera or Spur-thighed tortoise [4]

The type strain is PS6 = ATCC 700616 = CCUG 53180 and available from the Mollicutes Culture Collection, University of Florida.[3]
