Description

Technical Field

[0001] The invention relates to the field of microorganism sampling, and in particular to a device for extracting intestinal microorganisms in animals. Background Art

[0002] The intestine is considered to be the organ with the most concentrated energy metabolism and material metabolism in animals. Not only the metabolism of the intestine itself, but also the huge number of microorganisms in the intestine provide irreplaceable metabolic energy for the animal body. An important feature of the symbiotic intestinal microbial system is that intestinal microorganisms can change, shape and even affect the function of nutrient metabolism in animals. The intestine is the first susceptible organ of the body when harmful substances invade. In a normal intestine, the microbial flora maintains the health of the body by maintaining the ecological balance between symbiotic bacteria. However, when xenobiotics such as environmental pollutants enter the intestine through food or water, they will affect the growth, activity and community structure of symbiotic bacteria in the intestine. Changes in intestinal microorganisms are also an indicator of the sensitivity of animals to environmental changes. When taking intestinal microorganisms in the laboratory, some animals have small and long intestines. The traditional method of flushing out the contents of the intestine with a syringe is time-consuming and labor-intensive, and the effect is not good. The specific shortcomings include: sampling difficulties (such as: the intestine is easy to break, the intestine is difficult to fix), poor intestinal microbial flushing effect, etc., and the sampling environment does not meet the requirements (cannot be collected under low temperature and sterile environment).
