Figure 3

TEM of representative L-form culture, isolated from а placental sample (PL-12) in broth: (A) Cluster of small spherical L-bodies with low electron density, some of them with extremely small size - under 100 nm; (B) Small electron-dense and shapeless L-bodies associated with multiple vesicular elements; (C) Large L-body with condensed cytoplasmic material at the cell periphery. Spherical body inside the cell, invagination of cytoplasmic membrane and releasing of small elementary body are seen (EB); (D) Large “mother” cell (MC) containing shapeless and round elementary bodies of varying electron density and size. MC is in process of extrusion of elementary bodies by formation of protrusion (PR). Polymorphic L-form elements are seen around the MC; (E,F). Spherical or ellipsoid electron dense CWD cells of different size with well-expressed granular consistence.
