A good tracheal wash specimen includes a lot of mucus. A sample
that lacks mucus also lacks respiratory cells which are often caught
up within the mucus. The nature of the mucus is also informative.
Soft, stringy mucus is often seen with bacterial infections.
In horses, we routinely perform Prussian blue stains (for hemosiderophages)
and gram stains (for bacteria) on tracheal washes and bronchoalveolar
lavages.For more information on individual aspects of our tracheal
wash report, please refer to our cytology smear report. |
Tracheal wash from a cow with septic bronchopneumonia. Large numbers
of a mixed bacterial population are seen extra- and intra-cellularly
(within neutrophils). |
