摘　　要：本试验采用子宫内膜活检采样器采集子宫内容物样品 ,通过活菌计数、分离鉴定和药敏试验等对实验母猪产后子宫内细菌进行了研究 ,以探讨产后子宫内微生物的变化规律及对子宫复旧的影响。试验结果表明 ,在产后 0～ 1天之间 ,子宫内细菌数量呈直线增加 ,在产后第 7天时 ,子宫内细菌数量达到最多 ,此后其细菌数量逐渐下降 ;到产后第 2 5天时 ,子宫内细菌数量已降为 (7.35± 2 .5 4 )× 10 2个 / mg子宫样品。而细菌的种类在产后 1～ 7天之间较少 ,在产后第 7～ 13天间呈增长趋势 ,产后第 13天以后 ,细菌种类开始减少 ,直至接近于零。这说明产后子宫内环境经历了从污染到净化的过程 。The number of bacteria, the bacteria separation and identification, and the sensitively of the bacteria to antibiotics were studied for sow through uterine sample, taken by biopsy needle of the endometrium during the uterine involution. Objectives of the study were to reveal changes of bacteria in the uterus of the postpartum and effects of uterine involution. The results showed that the number of bacteria in the uterus of the postpartum sows increased rapidly between day 0 to 1 postpartum, and reached the peak level at day 7 postpartum, then declined gradually up to day 25 postpartum, the number of the bacteria reached to (7.35±2.54)×10~2/ml sample. The kinds of bacteria species maintained stable between day 1 to 7 postpartum, then increased between day 7 to 13. The results indicated that the kinds and the number of bacteria in the postpartum uterus vary with the ability of the uterus to prevent and the diameter of the cervix. It also indicated that the inner environment of the uterus experienced contamination to clearance events, until the uterus involution completed.
