Abstract
The objective of this study was todetect the percentage of Polymorph nuclear cells) PMNs (from the uterine smears using the local manufactured uterine cytobrush instrument, and to determine the echogenicity the intrauterine fluid byUltrasonography. 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.
Highlights
Endometritis is regarded as an important disease in mares which lead to subfertility with reduced an economical benefit by about 15% [1]

Summary
Endometritis is regarded as an important disease in mares which lead to subfertility with reduced an economical benefit by about 15% [1]. The major bacterial causes of endometritis in mares are E. coli and hemolytic streptococci from the vagina [3,4]. There are several methods have been used to diagnose endometritis in mares such as clinical examination; palpation per rectum; ultrasonography, vaginal examination, uterine culture, cytology, and endometrial biopsy [5]. Endometritis in mare usually associated with accumulation of amount of fluid in the uterus [3]. It has been reported that Mares with the presence of intrauterine fluids following inflammation had a shorter inter-ovulatory interval which has been observed after premature regression of the corpus luteum which results in the premature release of prostaglandins [6,7]
