Abstract

The invention relates to a culture medium suitable for clostridium difficile, and a preparation method thereof, and belongs to the technical field of microbial cultivation. The preparation method is used for solving a problem in the prior art that culturing effect of conventional culture medium on clostridium difficile is poor. The culture medium comprises composite ingredients such as peptone and dehydrated beef heart infusion, and also comprises complement components such as glycine and laminine. It is shown by experiment results that culture effect of the culture medium on clostridium difficile is excellent, and the culture medium possesses important implication in study on the biological characteristics of clostridium difficile and on treatment of clostridium difficile infection.

Description

technical field [0001] The invention relates to a culture medium suitable for Clostridium difficile and a preparation method thereof, belonging to the technical field of microorganism cultivation. Background technique [0002] Clostridium difficile (Clostridium difficile) is an obligate anaerobic bacterium of the genus Clostridium, which is very sensitive to oxygen and difficult to isolate and culture, hence the name. It was discovered in 1935, but it was not taken seriously until 1977 when it was discovered that this bacteria was related to pseudomembranous colitis caused by long-term clinical use of certain antibiotics (ampicillin, cephalosporin, erythromycin, clindamycin, etc.). Clostridium difficile is widely distributed in natural habitats such as soil, hay, sand, feces of some large animals (cows, donkeys, and horses), and in the feces of dogs, cats, rodents, and humans, in addition to being abundant in Clostridium difficile is often found in the feces of infants in t...
