2.2 Storage of Quality Control Strains
The storage process for strains used for quality control purposes must be standardized to reduce the chance of contamination or changes in growth characteristics. This can be achieved by using frozen stocks or using standardized strains from commercial sources. The following procedures (Sections 2.3 and 2.4) can be used to prepare quality control strains of rapidly growing bacteria, such as Staphylococci, most Tensorcocci, Enterobacteriaceae, and Pseudomonas aeruginosa. These procedures must be modified for the preparation and use of Neisseria, Haemophilus, Mycobacterium, and fungi. If the strain is from a commercial source, use it according to the manufacturer's instructions. 2.3 Preparation of Frozen Strains
2.3.1 Quality control strains are generally prepared from lyophilized strains from ATCC and revived according to ATCC instructions. 2.3.2 Use a sterile loop to streak the revived bacterial suspension onto two or three TSA agars with 5% sheep blood, and incubate for 18h to 24h at a suitable environment and temperature (see Table 1). 2.3.3 After incubation, check the purity by colony morphology. Perform biochemical tests if necessary. Suspend sufficient bacteria in 50ml to 100ml of cryopreservation medium. The cryopreservation medium can be sterile defibrinated sheep blood, rabbit blood, skim milk or TSB, which contains 10% to 15% glycerol at a final concentration. If these frozen strains are to be used to inoculate the test medium, the turbidity of the suspension should be adjusted to 0.5 McFarland standard (1 to 2×10°CFU/mL) before freezing. The suspension of gonorrhea bacteria should be adjusted to 1.0 Jaffarland standard. The bacterial suspension must contain sufficient viable bacteria to continue to be subcultured after a freeze-thaw cycle. 2.3.4 Dispense a small amount (0.5mL~1.0mL) of the bacterial suspension into small sterile glass or plastic bottles. Prepare enough quality control culture bottles to last for one year. Check purity before quality control testing. 2.3.5 Store the vials at -50C or lower for future use. The vials can be stored in the gas phase of an ultra-low temperature freezer or liquid nitrogen tank. The strain can be stored indefinitely at temperatures below -70C, but can only be stored for one year at -50℃~-70℃, and should not be stored at temperatures above -50C.
2.3.6 When needed, take a vial of quality control culture from the refrigerator or liquid nitrogen tank and thaw it quickly, and it can be used for testing or preparing working quality control culture. Secondary cultures can also be used for testing, and single colonies can be obtained by inoculating a solid culture medium. After incubation, use a single colony for testing or inoculating agar slants or plates for use as the main working quality control strain. Unused bacterial suspension should be discarded and not reused after freezing.
2.4 Working Quality Control Cultures
2.4.1 The quality control culture should be replaced after no more than three generations of frozen quality control culture. Excessive passages increase the chance of phenotypic changes. 2.4.2 To prepare working quality control cultures, inoculate an agar slant or plate with the frozen quality control culture and incubate overnight or until sufficient volume is obtained. These cultures on working agar slant or plates should be stored at 2C to 8°C, or at room temperature, for four weeks. After further passage, the culture should be checked for purity and typical colony morphology. 2.4.3 Working frozen cultures can also be prepared from frozen quality control cultures using the steps described in Section 2.3. Either the original stock bottle or the working quality control strain can be used to inoculate the test medium.
2.4.4 The working quality control strain of anaerobic bacteria should be stored in meat culture medium or other suitable anaerobic broth medium, or frozen preservation 4
strains should not be used agar slant or plate. 2.5 Culture medium detection process
WS/T232-2002
2.5.1 The working quality control strain is transferred to the culture medium, and after incubation, 3~5 individual colonies are suspended in a small amount of sterilized TSB and incubated for 4h~5h. Use a spectrophotometer to adjust the turbidity to 0.5 McFarland standard or 0.08~0.1 at 625nm absorbance. Alternatively, prepare the bacterial suspension directly from the overnight growth and adjust the turbidity in the same way. Regardless of which method is used to determine the turbidity of the inoculum, the colony count should reach (1~2)×10°CFU/mL. If the frozen culture has been adjusted to this range, the dilution can be prepared directly from the thawed culture. In order to obtain bacteria with appropriate vitality after freezing, for microorganisms that are sensitive to freezing (such as Neisseria gonorrhoeae), the count during freezing should reach (3-6)×10°CFU/mL (1.0 McFarland). 2.5.2 To test the nutritional capacity of the culture medium, dilute the basic bacterial suspension 1:100 with saline or purified water, and streak inoculate with 10μL inoculation loop or 0.01mL of the diluted suspension on each test culture medium to achieve a concentration of (12)×10*CFU/plate. If this operation does not ensure the formation of single colonies on a specific test culture medium, the inoculum should be diluted 10 times again. 2.5.3 To test the inhibitory capacity of the selective culture medium, dilute the basic bacterial suspension 1:10 with saline or purified water, and streak inoculate with 10μL loop or 0.01mL of the diluted suspension on each test culture medium to achieve a concentration of (1-2)×105CFU/plate. To prevent excessive growth on the selective culture medium, it may be necessary to dilute the inoculum 10 times. 2.5.4 To test the growth effect of the culture tube, inoculate with a 10μL loop or 0.01mL of the basic bacterial suspension. If necessary, adjust the concentration of the inoculum.
2.5.5 Incubate the inoculated culture medium under the conditions of Table 2, normally at 35°C for 18h-24h or 42h-48h. Chocolate agar and selective culture medium for the isolation of pathogenic Neisseria must be incubated in a 5%-10% carbon dioxide environment, and the results are checked at 18h-24h and 42h-48h. For anaerobic bacteria, it is usually cultured in an anaerobic environment rich in carbon dioxide for at least 48h. For Campylobacter agar, incubate in a microaerobic environment rich in carbon dioxide at 42°C for 48h. 2.6 If Explanation
If the test strain grows fully in the culture medium listed in Table 1 and forms a typical colony morphology, the culture medium is considered to be satisfactory. For selective culture media, some bacteria are inhibited, while the desired bacteria grow fully. In some cases, the appropriate color or hemolysis reaction shown in Table 1 must be produced.
2.7 Reporting quality control data to the user
2.7.1 Culture media listed in Table 1
The manufacturer should indicate on the label, technical manual or other documents that the tested product meets this standard. The manufacturer should also indicate other tests such as sterility test and pH determination.
2.7.2 Culture media not listed in Table 1
The manufacturer must report to the user the special quality control steps required, including: the strain used for testing, pH, evaluation of operating standards, the response of the strain to be tested, and evaluation of contamination. The test results of each batch do not need to be reported one by one, but proof should be provided to show that the quality control standards of the product are met. The batch number and shelf life should be indicated in the report.
Culture media not listed in Table 1 should be tested by the user. 2.8 Transportation and storage
Culture media should be prevented from excessive water loss during transportation and should be protected and kept warm. Manufacturers should consider transportation and storage conditions when setting expiration dates.
3 Tests to be performed by the user
3.1 Operational tests
As stated above, all user-prepared culture media should be tested in accordance with the above regulations. For culture media not listed in Table 1 and the following culture media, namely Campylobacter agar and culture media for selective isolation of pathogenic Neisseria (listed in Table 2), the user must test each batch of culture media. Users who obtain culture media distributed from other places in non-commercial form should also follow the rules in this document. Manufacturers (laboratories preparing culture media) should also perform quality tests applicable to the merchant. 3.2 Other quality assurance standards
Users of commercial culture media must check each batch of culture media for: cracks in the plate, uneven filling, cracks in the culture medium, hemolysis (blood agar), freezing, excessive bubbles or spots, and contamination. 3.3 Reporting of defects
If the culture media is found to be defective, the laboratory should record the results and notify the manufacturer. These include: failure to grow, failure to produce colonies of the expected size, or evidence of contamination, drying, or cracking. The manufacturer should have appropriate corrective actions, which should also be recorded in the laboratory. These situations do not necessarily require a change of culture medium. The user can perform additional tests to identify the cause and correct it. Table 3 Comparison of Chinese and English names of culture media

Report phone number: (010)685335333 Defect Report
If the culture medium is found to be defective, the laboratory should record the result and notify the manufacturer. These include: failure to grow, failure to produce colonies of the expected size, or evidence of contamination, drying, or cracking. The manufacturer should have appropriate improvement measures, which should also be recorded in the laboratory. These situations do not necessarily require changing the culture medium. The user can perform additional tests to find out the cause and correct it. Table 3 Comparison of Chinese and English names of culture media
