BACTERIA
A B
FIGURE 21–6A Bacilli engulfed by a leukocyte. FIGURE 21–6B Extracellular bacteria from
Note vacuoles (PB ×1000). same specimen as Figure 21-6A. Extracellular
bacteria alone may indicate contamination.
Presence of intracellular bacteria may rule out
contamination (PB ×1000).
C D
FIGURE 21–6C Cocci engulfed by a monocyte FIGURE 21–6D Multiple organisms, including
(PB 31000). yeast and cocci, most likely contamination from
an intravenous line (PB ×1000).
