Description

Technical Field

[0002] Microorganisms are a general term for a class of organisms, including bacteria, viruses, fungi, etc., covering many types of beneficial and harmful species, widely involved in food, medicine, industry and agriculture, environmental protection, sports and many other fields, and closely related to humans. In Chinese textbooks, microorganisms are divided into the following 8 categories: bacteria, viruses, fungi, actinomycetes, rickettsia, mycoplasma, chlamydia, spirochetes. Some microorganisms can be seen with the naked eye, such as mushrooms belonging to fungi. There are also microorganisms that are a class of "non-cellular organisms" composed of a few components such as nucleic acids and proteins.

[0003] Microorganisms are difficult to see with the naked eye and require the aid of an optical microscope or an electron microscope to be observed. When an infectious disease is prevalent, water source testing at the site of the outbreak must be carried out quickly. Pathogen collectors can collect pathogens in water bodies to facilitate scientific researchers and medical personnel to observe and experiment on the pathogens.

[0004] Currently available pathogen collectors usually directly inject water samples and place bacteria collecting cotton in the bacteria collecting tube, and then collect bacteria by letting the water sample flow through the bacteria collecting cotton.
