Subclinical endometritis has a major effect on the reproductive performance of dairy cows and also on the success of embryo collection. Thus it is important to minimize the number of false-negative diagnoses. In order to evaluate the question of whether or not a single cytobrush sample is representative of the whole endometrium, 53 German Holstein embryo donor cows in the northwest of Germany were examined via the cytobrush method at three different localizations of the uterus: the uterine body about 0.5 cm cranial of the cervical canal and both uterine horns about 1.5 cm cranial of the bifurcation. Although the mean percentage of polymorphonuclear neutrophils at the three locations is not significantly different ( = 0.64), the individual variations lead to the conclusion that more than one sample of the endometrium should be taken into account when diagnosing subclinical endometritis in embryo donor cows.
亚临床子宫内膜炎对奶牛的繁殖性能以及胚胎采集的成功率都有重大影响。因此，尽量减少假阴性诊断的数量非常重要。为了评估单个细胞刷样本是否能代表整个子宫内膜，对德国西北部的53头德国荷斯坦胚胎供体奶牛通过细胞刷方法在子宫的三个不同位置进行了检查：子宫体位于宫颈管头侧约0.5 cm处，两个子宫角位于分叉头侧约1.5 cm处。尽管这三个位置的多形核中性粒细胞的平均百分比没有显著差异（ = 0.64），但个体差异得出的结论是，在诊断胚胎供体奶牛的亚临床子宫内膜炎时，应考虑采集不止一个子宫内膜样本。
