title: Ultrastructural features of Mycoplasma gallisepticum in tracheal explants under transmission and stereoscan electron microscopy.
abstract: Ultrastructural features of Mycoplasma gallisepticum in tracheal explants were examined using the transmission and stereoscan electron microscope. The organisms were characteristically cocco-bacilliform except when in close contact with the host cells when they assumed an elongated and irregular form characteristically terminating in a bleb which was often embedded in the cell surface. In such organisms there were peripherally aligned fibrillar structures oriented towards the bleb which may have a functional relationship with a probing or moving habit of the mycoplasma.
