This has given rise to a growing demand for pathologists experienced in cytological diagnosis. PROCEDURE 1. Vaginal cytology can be performed in any practice due to its simplicity and the limited equipment necessary (speculum, cotton wool wad, slide, staining and microscope). Tracking changes in the morphology of desquamated vaginal epithelial cells provides a convenient means of assaying changes in estrogen levels. Direct smears from brushings can also be made with a quick rolling motion of the brush on glass slides. Walter B, Feulner H, Otzdorff C, Klein R, Reese S, Meyer-Lindenberg A. Theriogenology.

The oestrus is characterised by a high cell number, initially superficial cells with pyknotic nuclei, later anucleated squamous cells that are located in cell nests. The exfoliated cells reflect the hormonal, in particular the oestrogenic state, of the bitch. A post-bronchoscopic sputum may be examined when the expectorated sputum is negative. The switch to metoestrus is associated with a large number of neutrophil granulocytes and a sudden change of cytology within 24-48 hours. The complete absence of inflammatory cells is diagnostic in these cases! Because the results are rapidly available, it is a useful addition to gynaecological examination to differentiate the stage of the cycle (anoestrus, prooestrus/oestrus, metoestrus) and to diagnose infectious, inflammatory and tumorous conditions in the bitch. of amplecellular material may be obtained.
