Figure 1: Cytospin smear of cerebrospinal fluid collected from the atlanto-occipital space in a 1-year-old intact male Keeshond with fever and spinal pain.

The cytospin smears consist mostly of non-degenerate neutrophils with moderate macrophages (arrows). Macrophages are not vacuolated or phagocytic (“non-reactive”) (modified Wright’s stain).
