Abstract: The changes in the kinds and percentages of the epithelial and inflammatory cells of the external os region of the uterine cervices of the river buffaloes during three different stages of pregnancy were studied by microscopic evaluation of mucus smears which had been prepared by wet swab sampling of mucus from the external os of the pregnant buffaloes� uterine cervices. The mucus smears were stained by Giemsa�s staining method. The present study revealed evidence that changes in the percentages of the vacuolated and unvacuolated epithelial cells, lymphocytes, eosinophils and basophils were not significant statistically, but changes in the numbers and percentages of neutrophils in the three different stages of pregnancy period were statistically significant. We also found that changes in the number and percentage of monocytes (macrophages) between the second and third stage of pregnancy was not significant, but the difference between the first stage of pregnancy and the two other stages was statistically significant. We concluded that the numbers and percentages of neutrophils and monocytes (macrophages) increase significantly as the pregnancy progresses.
