Background

When the pathogenic microorganisms in the water body are detected, the water body needs to be sampled and collected, and aseptic operation is required to be paid attention to water sample collection so as to prevent mixed bacteria from being mixed. And (4) selecting a filter membrane with a proper pore diameter according to the experimental setting, and filtering the water body. For turbid water, the method is recommended to be used for standing and separating suspended particles before filtration, and the suspended particles are firstly filtered by a large-aperture filter membrane and then filtered by a small-aperture filter membrane. After the sample information is marked, the sample information is quickly frozen by liquid nitrogen or placed in a foam box filled with dry ice, and the sample information is transported back to a laboratory as soon as possible in a dark environment and stored in a refrigerator at the temperature of minus 80 ℃, and then the sample information is sent by the dry ice.

At present, most of existing water body pathogenic microorganism collecting devices are simple in structure, poor in preservation effect, difficult to complete a large number of samples, and limited in sample quantity and relatively low in detection data reliability. Therefore, there is a need for a novel collection of aquatic pathogenic microorganisms that overcomes the above-mentioned deficiencies.
