Comparative Evaluation of Endometrial Cytology by Cervical Aspiration and Cytobrush Techinques.

Cytological samples were collected from 10 healthy controls, 43 repeat breeders and 8 clinical endometritis animals by cervical aspiration and cytobrush method. The cytological smears were stained and counted under oil immersion lens of a light microscope. The mean neutrophils count obtained through cervical aspiration was 0.29±0.12, 3.5±1.86 and 71.75±7.65; and through the cytobrush was 0.7±0.28, 3.38±2.11 and 41.25±5.98% in Group I, Group II and Group III, respectively and differed significantly. In repeat breeders, Cytobrush yielded similar result compared to cervical aspiration for identification of subclinical endometritis when 5% and 10% neutrophils threshold were taken to define subclinical endometritis.
