Thirty (Arabian) repeat breeder mares were used. Animals were examined through rectal palpation and ultrasound. Mares were divided into 4 groups depending on the results of: 1) the amount of intrauterine fluid using ultrasound; 2) the endometrial samples were collected during estrus cycles, 3) the numbers of uterine epithelial cells and PMNs using locally manufactured cytobrush tool, 4) the number of lymphocytes. The results showed that the incidence of endometritis had significantly related to that age of the animals. The number of PMNs were significantly different between groups. The mean number of PMNs was 1.63±0.23, 3.34±0.18, 4.78±0.26 and 5.26±0.46 in G1, G2, G3 and G4, respectively. The echogenicity of the accumulated fluid in the endometrial lumen was significantly associated with the percentage of lymphocytes. The mean number of lymphocytes was 1.02±0.42 and 1.84±0.37%, in G3 and G4 respectively. This study concluded that the cytobrush technique is rapid, cheap, safe technique and easy to obtain samples from mare's uterus in the field. Consequently, Ultrasound and cytological techniques could be recommended for diagnosis of endometritis in mares. %U https://www.vetmedmosul.com/article_169657_4c1758dc6339608faf49d561bc24187d.pdf
