胆道感染细菌学的研究,在很长一段时间内主要集中在需氧菌方面.七十年代以来,由于厌氧菌培养技术取得重大进展,厌氧菌在感染胆汁标本中的检出率大大提高,推动了胆道厌氧菌的研究.目前,其作用和意义日益引起重视,对厌氧菌感染的治疗,尤其是药物治疗.也有了不少新的认识.微生物学特征厌氧菌广泛地存在于人体肠道内,是重要的正常菌群.结肠内每克粪便的厌氧菌可高达10~(10～12)个,厌氧菌和需氧菌的比例超过100∶1.肠道内的这些厌氧菌是条件致病菌,在某些致病因素影响下菌群异位(Translocation),转移
The study of bacteriology of biliary tract infections has been mainly focused on aerobic bacteria for a long period of time. Since the seventies, great progress has been made in the cultivation of anaerobic bacteria, and the detection rate of anaerobic bacteria in infected bile specimens has been greatly increased , Promote the study of biliary anaerobic bacteria.At present, its role and significance of increasing attention, the treatment of anaerobic infections, especially drug treatment has also been a lot of new understanding.Microbial characteristics Anaerobic bacteria widely exist In the human intestine, it is an important normal flora, and the number of anaerobes per gram of stool in the colon can be as high as 10 ~ (10 ~ 12), the ratio of anaerobic to aerobic bacteria is over 100: 1. Anaerobic bacteria are opportunistic pathogens, under the influence of certain pathogenic factors flora translocation (Translocation), transfer
