Fig. 6 — Representative examples of exfoliated epithelium and other inclusions commonly seen on a coyote vaginal smear (480 ×). A) Proestrus, dotted arrow indicates a parabasal cell, dashed arrow indicates an intermediate cell, and solid arrow indicates a red blood cell. Amorphous debris and mucus is conspicuous in the background. B) Estrus, superficial cells with pyknotic nuclei and spermatozoa are shown; note the relatively clear background as compared to A and C. C) Diestrus, dashed arrows indicate intact white blood cells (neutrophilic leukocytes). Also, parabasal and intermediate epithelial cells have reemerged, and red blood cells, mucus, and amorphous debris are abundant.
