母犬阴道和子宫的微生物区系

Vaginal and Uterine Microflora Of Adult Dogs

发情周期不同阶段的母犬阴过来样８２只和子日采样７８只中确定需氧与厌氧微生物．平均总细菌数：８２只１００ｍｇ阴道内容物ｌｏｇ５．０±ｌｏｇ１．５（ｌｏｇ２．４－ｌｏｓ８．８）。发情期的细菌数（ｌｏｇ７．８±ｌｏｇ０．７）放非发情期（ｌｏｇ４．４±ｌｏｇ１．０〕、怀孕期（ｌｏｇ５．９±ｌｏｇ１．３）和产后期（ｌｏｇ５．１±ｌｏｇ１．５）的母犬明显为高（Ｐ＞０．０５）。从阴道分离出的普通微生物为类细菌科、待球菌属、巴氏菌属和支原体属。从７８只子宫样品中４８只（占６８％）也分离出微生物。每１００ｍｇ子宫内容物中总细菌数范围为ｌｏｇ１．６－ｌｏｇ８．３，并分离出葡萄球菌属和支原体屁。尽管子宫内微生物与阴道相似，然而子宫内容物培养可进行单一分离出微生物，在大多数子宫内未见到病理变化。显然，阴道中微生物常常会进入子宫，然而它们很少引起子宫的感染。

82 vaginal and 78 uterine samples, which were obtained from mature bitches during different stages of the estrous cycle ,were studied for their aerobic and anaerobic microflora The mean SD of total bacterial counts/100mg of vaginal contents of 82 bitches was lo 5. 0.1. 5(log. 4-log8. 8) The count of the estrous stage (log7. 8±log0. 7)was significantly higher(P>0. 05) than that at the anestrus(log7. 8 ±log0. 7) was significantly higher(P>0. 05) than that at the anestrus (log7. 8±log0. 7) was significant- ly higher (P>0. 05)than the. at the .anestrus (1og,4.4±logl. 0. Pregnancy(1og5. 9±logl. 3) and post partum (log5. 1± 1. 5 ) stages The common microbe. isolated from the vagines were bacterioidaceae Streptococci , Pasteurella spp , and Mycoplasmas Microbes were also isolated from48(68/oo)of 78 uterine samples The range of total counts/100mg of uterine samples was from logl. 6 to log8. 3;Staphylococci and Mycoplasmas. were also isoated from the uterine contents The microflores found at vagines were similar to those found at uteri However ,the cultivation of vaginal samples can be used for single isolate identification No pathological findings were found in most uteri It was obviously that the microfloras at vaginas can migrate to uteri ,but they don't cause infections at uteri
