Attachment of Mycoplasma gallisepticum to the tracheal epithelium of fowls.

An electron microscopical study of fowl trachea infected with Mycoplasma gallisepticum showed slight to moderate changes at the cellular level. Mycoplasmas were demonstrated extra-cellularly and showed triple membranes, intracytoplasmic spaces, fibrillar nuclear areas and blebs. Blebs were seen attached to the plasma membrane of the epithelial cells.
