FIG. 3. Scanning electron microscopy of C. neoformans yeast cells. Cryptococcal cells were grown in SAB medium (ATCC 24067 [A] and H99 [C]) or SAB medium with 0.5 times the MIC of voriconazole (ATCC 24067 [B] and H99 [D]). The yeast cells shown are representative of those seen for each condition. The experiment was performed twice with similar results. Scale bars represent 2 µm.

Figure 1. Interaction of M. tuberculosis with the Surface of Pulmonary M Cells
C57BL/6 mice were challenged with 1 × 10⁷ virulent M. tuberculosis, Erdman strain, intratracheally. Tissue was processed for scanning electron microscopy.
(A) M. tuberculosis (arrowheads) adhere to and cause a tunneling of the M cell surface (arrows). Bar, 1 µm; magnification, 2,500×.
(B) Higher magnification of bacteria in (A), with cluster of M. tuberculosis (arrowhead) adhering to microvilli on the M cell surface (small arrows). Bar, 1 µm; magnification, 10,000×.
(C) Higher magnification of bacillus in (A), showing microvilli adherence to bacterial surface as well (arrows). Bar, 1 µm; magnification, 13,000×.

This is a comparison of thin section transmission electron microscopy (top) and scanning electron microscopy (bottom).
Both images show virus budding from mammalian cells.
