Aerobic and anaerobic microflora were identified and quantitated in 82 vaginal and 78 uterine samples obtained from mature bitches during different stages of the estrous cycle. The mean +/- SD of total bacterial counts/100 mg of vaginal contents of the 82 bitches was log 5.0 +/- 1.5, ranging from log 2.4 to log 8.8. The count at the estrous stage (log 7.8 +/- 0.7) was significantly higher (P less than 0.05) than that at the anestrus (log 4.4 +/- 1.0), pregnancy (log 5.9 +/- 1.3), and postpartum (log 5.1 +/- 1.5) stages. The common organisms isolated from the vaginas were Bacteroidaceae, streptococci, Pasteurella spp, and mycoplasmas. Organisms were isolated from 48 (68%) of 78 uterine samples. The range of total counts/100 mg of uterine contents was from log 1.6 to log 8.3. Staphylococci and mycoplasmas were frequently isolated from the uterine contents. Although many uterine microfloras were similar to vaginal microfloras, some uterine culture had a single isolate identified. There were no pathologic findings in most of the uteri. Seemingly, vaginal bacteria frequently flow into the uterus, yet they rarely cause uterine infection.
对82份阴道样本和78份子宫样本中的需氧和厌氧微生物区系进行了鉴定和定量分析，这些样本取自处于发情周期不同阶段的成年母犬。82只母犬每100mg阴道内容物的细菌总数平均值±标准差为log 5.0±1.5，范围为log 2.4至log 8.8。发情期的细菌计数（log 7.8±0.7）显著高于（P<0.05）乏情期（log 4.4±1.0）、妊娠期（log 5.9±1.3）和产后（log 5.1±1.5）。从阴道分离出的常见微生物有拟杆菌科、链球菌、巴氏杆菌属和支原体。从78份子宫样本中的48份（68%）分离出了微生物。每100mg子宫内容物的细菌总数范围为log 1.6至log 8.3。葡萄球菌和支原体经常从子宫内容物中分离出来。尽管许多子宫微生物区系与阴道微生物区系相似，但一些子宫培养物中鉴定出了单一分离株。大多数子宫没有病理发现。显然*，*阴道细菌经常流入子宫，但很少引起子宫感染。
最后一句中“Seemingly, vaginal bacteria frequently flow into the uterus, yet they rarely cause uterine infection.”中的“，”为原文中的标点符号，可能存在错误，正常应该是逗号“，” 。
