Introduction
Vaginal smears can be used to determine the stage of the oestrous cycle. Smears are generally stained with Leishman's or a Trichrome stain such as Shorr's.
Vaginal Smears
- At the onset of pro-oestrus, large numbers of erythrocytes are present.
- When true oestrus occurs, the nuber of erythrocytes is reduced, and the smear consists of superficial cells from the stratified squamous epithelium. Such cells include:
- Anuclear cells
- Cells with pyknotic nuclei
- Large intermediate cells
- Towards the end of oestrus, polymorphonuclear neutrophil leukocytes appear. These become the dominant cell type during metoestrus.
- In anoestrus,different cell types are present,these are:
- Nucleated basal of the stratified squamous epithelium
- Intermediate cells of the stratified squamous epithelium
- Few neutrophils
