1. Ensure the pure culture of the strains, be careful not to use strains contaminated by other bacteria, and do not connect and cultivate them at close range.

These links would not have been made if viral particles were looked for via PCR methods. This is due to the fact that the patient's immune defence might be successful in eliminating the virus and hence removing any trace of where it came from. However, when specific antibodies are searched for in the same patient, they will be able to be detected because they stay within the blood for several years. Commercial immunoassay tests to detect COVID-19 include a dual ELISA test to be performed. This detects specific IgA and IgG against the virus in the blood of infected patients. There is also an automated fluorescent immunoassay system to measure quantitatively or semi-quantitatively the concentration of the targeted analyte, which can be the viral antigen or IgM/IgG. antibody diagnostic kit, rapid antibody test kit, rapid antibody diagnosis,covid-19 antibody diagnosis, antibody detection kit Shenzhen Uni-medica Technology Co.,Ltd , https://www.nbunimed-global.com
2. Strictly control the number of passages of the bacteria, reduce mechanical damage, and ensure the vigor of the bacteria.
3. Appropriate low-temperature storage of strains. Low-temperature strains such as mushrooms and shiitake mushrooms are beneficial to preserve the vigor of mycelium at 4°C, and high-temperature strains such as straw mushrooms are beneficial to preserve the vitality of mycelium at 16°C. .
4. Avoid multiple passages in a single or the same medium; strains should not be used for too long, as over-age strains will age, and aging and degradation are organically linked, and strains with weak viability are prone to degradation.
5. Strains should be rejuvenated on a regular basis, under conditions of suitable temperature, suitable pH, sufficient oxygen, and free of bacteria.
6. Perform spore separation every year to discover excellent strains through sexual reproduction, and consolidate the genetic characteristics of excellent strains through tissue separation.
