Problems solved by technology

Both Stuart transport solution and Markus transport solution add 0.1-1% agar to increase the viscosity to isolate the air. Since the agar is solidified at room temperature, it is easy to form faults during the process of placing the specimen, so that the tissue specimen cannot be separated from the air. Completely isolated, affects the survival ability of bacteria, not a good substance to increase viscosity

Abstract

The invention relates to transport fluid for culturing helicobacter pylori in a gastric biopsy specimen and a preparation method and application thereof. Viscosity is enhanced, pH value is increased appropriately and anti-mixed bacterium medicaments are increased, so that the survival of the helicobacter pylori in the gastric biopsy specimen is protected and the preservation time of the specimen is prolonged. The transport fluid has high practical value. Bacteria detection rate is not affected if the specimen is submitted within 24 hours after being collected. The survival rate of the helicobacter pylori preserved at room temperature within 24 hours is over 50 percent. The transport fluid is suitable for detection in hospitals and inspection institutions in different levels.

Description

technical field [0001] The invention relates to a transport liquid for microorganism culture and its preparation method and application, in particular to a transport liquid for gastric biopsy tissue specimen Helicobacter pylori culture and its preparation method and application. Background technique [0002] Helicobacter pylori (Hp) is a pathogenic bacterium that can colonize the gastric mucosa for a long time. It is Gram-negative, curved or slightly spiral-shaped, 2.5-5mm long and 0.5mm thick. The bacteria are usually distributed in uneven groups in the gastric alveolar and glandular cavity. It can secrete a variety of exotoxins, which can damage the gastric mucosal epithelium. The secreted catalase, lipase, phosphatase, proteolytic enzymes and toxins can damage gastric epithelial cells and cause gastric mucosal inflammation. [0003] Studies have shown that Helicobacter pylori infection is closely related to gastric diseases such as chronic gastritis and peptic ulcer, and...
