Abstract

The invention discloses a prevotella intermedia (Pi) culture medium, which is characterized in that: a formula for preparing 1,000 ml of the culture medium contains 15g of peptone, 8g of beef heart infusion, 5 mg of protohemin, 10 mg of vitamin K1, 5.5g of sodium chloride, 15g of agar, 4 mg of doxycycline, 20 mg of metronidazole, 90 ml of sterile sheep blood and the balance being distilled water.Compared with the prior art, the Pi culture medium has the characteristics of reliability in detection and high separation rate of Pi.

Description

technical field [0001] The invention relates to the field of culture of microorganisms in the oral cavity, in particular to an intermediate Prevotella culture medium. Background technique [0002] Periodontal disease is a common oral disease with a high incidence worldwide. Prevotella intermedia (Pi) is a melanin-producing G-anaerobic bacterium. A large number of studies have shown that Pi is closely related to infectious diseases such as periodontitis, periapical disease and pericoronitis. The current Pi test method is mainly subgingival plaque sampling for polymerase chain reaction (PCR), which requires DNA extraction and PCR primer design for the sample, and requires PCR-related instruments and equipment, which is expensive , the operation is complex. Microbial culture is a technology that uses artificial methods to grow and reproduce microorganisms, and selective medium is a medium designed to promote or inhibit certain types of organisms (such as cells or bacteria, et...
