Description

Technical Field

[0001] The invention relates to the field of biotechnology, and in particular to a Legionella culture detection kit and application thereof. Background Art

[0002] Legionella is a Gram-negative bacillus that is widely found in water and soil in natural and artificial environments. It is a highly epidemic respiratory pathogen. Inhalation of Legionella-contaminated aerosols, drinking water contaminated with Legionella, or contact with contaminated water sources on wounds may cause Legionnaires' disease.

[0003] Legionnaires' disease is a new infectious disease that has emerged with the progress of human society and economic development. It has become an important public health issue faced by modern urban development. Many countries and regions in the world have reported sporadic cases of the disease. Most parts of my country have reported cases of Legionnaires' disease. Due to the lack of systematic etiology and epidemiological survey data, the current status of Legionnaires' infection and the prevalence of Legionnaires' disease are unclear. Recent research results show that the infection rate of Legionnaires' disease in people with respiratory or lung diseases is between 6.0% and 17.5%.

[0004] According to the IgM antibody test of the target population in public places in various places, the antibody positive rate of the target population in public places is 4.63%, and that of employees in key industries is 12.70%. There are even reports that the positive rate of the exposed population can be as high as 53%, indicating that Legionella has posed a potential threat to employees in key industries. Regular cleaning and supervision of public places and control of biological pollution from the source are of great significance to reducing the risk of Legionella infection.

[0005] The methods currently used for laboratory diagnosis of Legionnaires' disease are: isolation of the microorganism on culture medium, antigen detection in urine, microscopy, detection of bacterial deoxyribonucleic acid (DNA), and use of paired serology.

[0006] Urine antigen testing and sputum culture or bronchoalveolar lavage fluid are the most appropriate clinical tests for Legionella. Patients who may have been exposed to Legionella during an outbreak should also be tested for Legionnaires' disease, including culture.

[0007] Legionella culture is usually the most specified test method and has a high specificity, although the sensitivity of culture varies from 50% to 80%. Identification of Legionella after culture is the definitive method for diagnosing Legionnaires' disease and is therefore the "gold standard". Iron, L-cysteine, alpha-ketoglutarate, and charcoal yeast extract agar buffered with organic buffer (ACES) are the preferred growth media for isolation. Antibiotics can be added to BCYE alpha-medium to avoid overgrowth of other bacteria to increase the selectivity of the medium.

[0008] The current gold standard for diagnosing Legionnaires' pneumonia is positive bacterial isolation and culture, with a specificity of 100% and a sensitivity of 50% to 70%. Legionnaires can only grow on special culture media, and the isolation rate of environmental samples is as high as 50% or more. The positive rate of biological sample culture detection is related to the severity of the disease. The detection rate of Legionnaires in mild patients is 15% to 25%; the detection rate of Legionnaires in severe patients with respiratory failure is >90%.

[0009] The disadvantages of the current culture method are: it is easily affected by the quality of specimen collection and operation technology, the separation effect is poor, the positive rate is inconsistent; it takes a long time, about 7 to 10 days; the culture medium is expensive. These drawbacks lead to certain difficulties in the clinical diagnosis of Legionella pneumonia. Specifically:

[0010] 1) JP2021090403A introduces a culture medium with added cyclodextrin, which can replace the role of activated carbon or serum, but has no promoting effect on the growth of target bacteria and the detection of target bacteria in samples;

[0011] 2) Although an indicator is added to the Legionella selective isolation medium of CN101643713, it is added on the basis of the activated carbon plate, which does not promote the growth of the target bacteria and has no promoting effect on detection;

[0012] 3) CN112888790A introduces a carbon-free culture medium, but the culture medium includes: serum, wherein the concentration of the serum is 1% to 35%.

[0013] For culture, the culture medium of the existing culture technology is a plate with added activated carbon, which has no color development function, low clinical isolation rate, and poor inhibition of non-target bacteria. The cost of the plate without activated carbon with added serum or BSA is relatively high. The plate with cyclodextrin replacing serum or activated carbon only utilizes the adsorption effect of cyclodextrin to relieve the inhibition of metabolites on Legionella, and has no obvious effect on sample separation, especially the inhibition of substances in respiratory samples on Legionella.

[0014] On the other hand, for sample pretreatment, although hydrochloric acid sample pretreatment reagent is included in the national standard, hydrochloric acid treatment has a greater impact on Legionella, which will affect the detection of Legionella. It also has no digestive function, and the Legionella contained in mucus is not easily released, affecting the detection of the target bacteria. Summary of the invention

[0315] The cultured Legionella were inoculated on plates with formulations as shown in Examples 1 to 63 and Comparative Examples 1 to 4, respectively, and cultured at 35 to 37° C., 5% to 10% CO 2 for 48 to 72 hours. The results were observed and shown in Table 1.

[0316] Table 1

[0317]

[0318]

[0319] From the results, adding reagents can promote the growth of target bacteria, and the plate provided by the present invention can significantly improve the growth of target bacteria. Removing or replacing some reagents will affect the growth of target bacteria.

[0320] Effect Example 2: Inhibition effect of non-target bacteria on different plates

[0321] The cultured non-target bacteria were inoculated on plates with formulations as shown in Examples 13 to 63, Comparative Example 2, and Comparative Example 4, and cultured at 35 to 37° C., 5% to 10% CO2 for 48 to 72 hours. The results were observed and shown in Table 2.

[0322] Table 2

[0323]

[0324]

[0325]

[0326]

[0327]

[0328]

[0329] From the results, it can be seen that the plate provided by the present invention has a more obvious inhibitory ability on non-target bacteria, can reduce the coverage and inhibition of target bacteria, and can improve the detection rate of target bacteria.

[0330] Effect Example 3: Digestion Effects of Different Pretreatment Reagents

[0331] The viscous sputum samples were diluted 1:1 or 1:2 using the pretreatment reagents of Examples 64 to 85 and Comparative Example 5, respectively, and treated for 5 minutes or 15 minutes to observe the dilution digestion effect. The results are shown in Table 3.

[0332] Table 3

[0333]

[0334]

[0335]

[0336] From the results, it can be seen that the viscosity of the reagent can be significantly reduced after the sample is treated with the pre-treatment reagent of the present invention.

[0337] Effect Example 4: Effect of sample pretreatment on the growth of Legionella

[0338] Freshly cultured Legionella was prepared into a bacterial suspension with a McFarland turbidity of 0.5 (about 1.5×10 8 ), and then diluted to (10 4 ), the diluted bacterial solution was diluted 1:1 or 1:2 with the pretreatment reagents as shown in Examples 64 to 85 and Comparative Example 5, and left for 5 minutes or 15 minutes, and 100 microliters were taken to coat two plates after the time was up, and the average number of colonies was taken for comparison. The control was diluted 1:1 or 1:2 with physiological saline, and left for 5 minutes or 15 minutes, and 100 microliters were taken to coat two plates after the time was up, and the average number of colonies was taken for comparison. The results are shown in Table 4.

[0339] Table 4

[0340]

[0341]

[0342] From the pure bacteria results, the sample pretreatment reagent treatment at 1:2 for 15 minutes had no significant effect on the growth of the target bacteria, indicating that the sample pretreatment had no effect on the growth of the target bacteria.

[0343] Effect Example 5: Inhibitory effect of pretreatment reagents on non-target bacteria

[0344] The cultured non-target bacteria were prepared into a bacterial suspension with a McFarland turbidity of 0.5 (about 1.5×10 8 ), dilute 1:1 with the sample pretreatment reagent as formulated in Example 64 to Example 85 and Comparative Example 5, and leave it for 5 minutes. After the time is up, take 100 μl of the three-zone inoculation plate to observe the growth of the target bacteria.

[0345] The control was treated with the same procedure by diluting the bacterial solution with physiological saline. After the time was up, 100 μl was taken and inoculated on a three-zone plate to observe the growth of the target bacteria. The results are shown in Table 5.

[0346] Table 5

[0347]

[0348]

[0349] From the results, it can be seen that the pretreatment reagent has a good inhibitory effect on non-target bacteria.

[0350] Effect Example 6: Detection rate of target bacteria after treatment with different pre-treatment reagents

[0351] Freshly cultured Legionella was prepared into a bacterial suspension with a McFarland turbidity of 0.5 (about 1.5×10 8 ), and then diluted to (10 6 ), take 100 μl and add it to 900 μl sample (10 5 ), dilute the diluted sample with the pretreatment reagents as shown in Examples 64 to 85 and Comparative Example 5 at a ratio of 1:1 and 1:2, respectively, and place for 5 minutes and 15 minutes, respectively. After the time is up, take 100 μl of three-zone lines and inoculate them on a plate with a formula as shown in Example 20 to observe the growth of the target bacteria.

[0352] The control was a sample diluted with physiological saline and treated in the same manner. After the time was up, 100 μl of the sample was inoculated in three zones on a plate having the formula of Example 20 to observe the growth of the target bacteria. The results are shown in Table 6.

[0353] Table 6

[0354]

[0355]

[0356] From the test results of the simulated samples, it can be seen that the detection rate of Legionella is significantly improved by using the sample inoculation plate treated with the pre-treatment reagent of the present invention.

[0357] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
