Abstract

Reproductive tract abnormalities especially in the uterus and ovaries of cows often results in infertility. The object of this study was to determine the relationship between the cytology of uterine and cervical mucosa and endometrial histopathology in normal and endometritic cows. In this study, the genital tracts of 131 slaughtered cows were collected. According to macroscopic appearances and histopathological evaluation, reproductive tracts were divided into normal and abnormal. Cytological samples were obtained from the discharges of cervical mucosa and uterine fluid that were collected by wet cotton swab and gentle aspiration. Differential cellular counts were carried on Giemsa stained smears of the mucosa. Comparison of cell densities of normal cows with endometritic cows showed significant differences (P<0.05) in the macrophage presence both by swab (0.00±0.00) and aspiration (0.16±0.55) methods. Comparison of cell densities in different grades of endometritis showed a significant difference (P<0.05) in the neutrophil percentage in cervical mucosa between the swabbing and aspiration methods. In this study, there were no significant differences in cell densities between the two collection methods in cows affected with either acute or chronic endometritis. However, there was significant difference in the neutrophil density in aspirated cervical mucosa compared to the swab collection in cows affected with subacute endometritis. Cytological methods can be useful for the diagnosis of clinical and subclinical endometritis of cows.
