Abstract

The present invention discloses a preparation method of a new type incubation medium, belonging to the medical inspection field. The method can promote growth of mycobacteria. The incubation medium comprises a solid part and a liquid part: the solid part is the modified Roche's incubation medium that is generally used at home and abroad and the liquid part consists of basic incubation medium, growth promoter and bacteria inhibitor. The incubation medium can not only promote growth of mycobacteria, but also inhibit other bacteria. The growing mycobacteria can form violet red bacteria colony on the solid inclined plane of incubation medium, which is beneficial to elementary appraisal. The incubation medium can shorten incubation time obviously, increase incubation positive rate considerably, very suitable for fast inspection of mycobacteria for the hospitals and the sanitation and anti-epidemic institutions.

Description

technical field [0001] The invention belongs to the technical field of medical testing, and in particular relates to a novel culture medium capable of promoting the rapid growth of mycobacteria and a preparation method thereof. Background of the invention [0002] Mycobacteria are a group of bacteria widely distributed in nature, some of which can cause human and animal disease. In recent years, the number of diseases caused by mycobacterial infection has been widely reported at home and abroad. In particular, secondary infections in immunocompromised patients and outbreaks of nosocomial infections have increased significantly. For the diagnosis of infectious diseases caused by mycobacteria, the diagnosis can be confirmed as long as the mycobacteria are cultured from the sample to be tested. [0003] At present, the modified Roche medium is commonly used at home and abroad to isolate and culture mycobacteria (see the Chinese Medical Association's clinical technical operati...
