Ultrastructural analysis of MDBK cells examined at 48 h.p.i. cells were infected and processed for TEM analysis as above. White arrow and arrowhead show the types of vesicles seen in mock-infected cells (A). The star indicates the vesicular structure found only in BVDV-infected cells (B). A higher magnification of the area in BVDV-infected cells (C) is indicated by the rectangle box. Notice the presence of various size vesicles enclosed in the large vesicular structures. Bars = 1 μm.
