本文所研究的问题,在国内外尚未见有报道。该研究证明,在天然牛黄及胆汁中,均存在埃希氏大肠杆菌;在产牛黄的同一个胆囊里,可有数株埃希氏大肠杆菌同时存在,在正常牛活体胆汁中,埃希氏大肠杆菌的总检出率为45.9％,并发现在一个胆囊里,数株埃希氏大肠杆菌转化结合胆红素为非结合胆红素的能力差异很大。在产天然牛黄的胆囊里均存在转化率高的埃希氏大肠杆菌,但在正常牛胆囊里的埃希氏大肠杆菌的转化率则较低。因此,植黄用的菌种,应选用天然牛黄及其胆汁中分离的转化率高的埃希氏大肠杆菌。
The problems studied in this paper have not been reported at home and abroad. The study shows that in natural bezoar and bile Escherichia coli exist; in the same gallbladder produced in the same gallbladder, there may be several strains of Escherichia coli co-exist, in normal bovine live bile, Escherichia coli The total detectable rate of bacilli was 45.9% and found that there was a large difference in the ability of several strains of Escherichia coli to convert conjugated bilirubin into unconjugated bilirubin in one gall bladder. Escherichia coli, which has a high conversion rate, is present in the gallbladder of natural bezoar but has a lower conversion of Escherichia coli in the normal gall bladder. Therefore, yellowing bacteria should be used in natural bezoar and bile isolated high-conversion Escherichia coli.
