A total of 368 uterine swabs were taken from mares in heat (n = 202) and from mares that were not in heat (n = 166). From 72 of the mares, two swabs were taken; one during either seasonal anoestrus or dioestrus, and one during oestrus. Swabs were taken during anoestrus/dioestrus in 94 other mares and during oestrus in the remaining 130 mares. Bacteriological cultures were done aerobically and classified as negative, insignificant or significant. There was a trend for more positive cytological specimens during oestrus than during anoestrus/dioestrus. The proportions of significant cultures were 12 of 202 (5.9%) in oestrous mares and 14 of 166 (8.4%) in anoestrous/dioestrus mares. Generally more insignificant than negative cultures were obtained during oestrus compared to anoestrus/dioestrus. Seven of 27 cultures that were classified as significant were associated with positive cytological specimens, and only 2 of 16 specimens that yielded pure cultures of E. coli contained neutrophils. Although the culture results did not differ significantly between the cycle stages, oestrus should be the preferred time for uterine examination.
共采集了368份子宫拭子，其中来自发情母马的有202份，来自未发情母马的有166份。72匹母马各采集了两份拭子，一份在季节性乏情期或间情期采集，另一份在发情期采集。另外94匹母马在乏情期/间情期采集拭子，其余130匹母马在发情期采集拭子。进行需氧细菌培养，并分为阴性、无意义或有意义。发情期的细胞学标本阳性趋势比乏情期/间情期更明显。发情母马中有意义培养物的比例为202份中的12份（5.9%），乏情期/间情期母马中有意义培养物的比例为166份中的14份（8.4%）。与乏情期/间情期相比，发情期获得的无意义培养物通常比阴性培养物更多。27份被分类为有意义的培养物中有7份与细胞学标本阳性有关，而在16份产生大肠杆菌纯培养物的标本中只有2份含有中性粒细胞。尽管不同周期阶段的培养结果没有显著差异，但发情期仍是子宫检查的首选时间。
