Relationship between the presence of intrauterine fluid and cervical bacteria in heavy draft mares before and after mating

概要

While intrauterine fluid (IUF) is observed as mucous in healthy mares during estrus, the presence of IUF during diestrus is an indicator of endometritis. Mating induces endometrial inflammation in healthy mares, called mating-induced endometritis, that disappears within 1–2 days after mating. On the other hand, it is also known that IUF remaining beyond 12 hr after mating can cause persistent inflammation, bacterial growth, and decreased fertility. This study aimed to investigate the relationship between the presence of IUF and cervical bacteria before and after mating. Mares were classified into three groups based on the degree of IUF: Grade 1 (G1), neither IUF nor echogenic lines at the inner lining of the uterus; Grade 2 (G2), small amount of IUF (<0.5 cm in diameter) or an echogenic lines in the intrauterine cavity; and Grade 3 (G3), obvious IUF (≥0.5 cm in diameter). The positive culture rates of G1, G2, and G3 mares before mating were 15.8% (n=6/38), 25.9% (n=7/27), and 31.8% (n=14/44), respectively, and did not differ significantly between the groups. After mating, the positive culture rates of G1, G2, and G3 mares were 18.2% (n=2/11), 56.1% (n=23/41), and 72.3% (n=34/47), respectively. The positive culture rates were significantly higher in G2 (P<0.05) and G3 (P<0.01) mares compared with G1 mares. These results from after mating suggest that not only mares with obvious IUF but also those with a small amount of IUF (<0.5 cm in diameter) or echogenic lines in the intrauterine cavity are at risk of mating-induced endometritis.
