Description

Method for testing microbial drug sensitivity test by using drug sensitivity indicator
Technical Field
The invention relates to a microbial drug sensitivity test, in particular to a test method for performing the microbial drug sensitivity test by using a drug sensitivity indicator.
Background
In recent years, because a large number of antibacterial drugs are widely used clinically, the drug resistance of bacteria is more and more common, some bacteria can simultaneously resist 2-7 drugs, the wide spread of drug-resistant strains brings great difficulty to clinical treatment, and in addition, clinical diagnosis and treatment means are continuously updated, so that diagnosis and treatment effects are improved, but more cross-infection opportunities are brought, and the immune state of an organism tends to be low. Of particular interest is the large shift in infection types, yet changes, which places greater demands on the clinical detection of microbial drug sensitivity.
At present, the domestic methods for detecting the drug sensitivity of microorganisms mainly comprise a paper diffusion method and a dilution method. The paper diffusion method is to stick the filter paper containing quantitative antibacterial drugs on the surface of the agar inoculated with the test bacteria, and judge the MIC value of the drugs to the microorganisms according to the growth condition of the bacteria, and the method has the defects of one-time detection of few drugs and incapability of quantifying the MIC value in clinical tests. The dilution method is to dilute the concentration of the antibacterial drug by multiple ratios, wherein the lowest drug concentration capable of inhibiting the visible growth of the flesh and eyes of the bacteria to be detected is the Minimum Inhibitory Concentration (MIC). The dilution method is usually carried out through a microbial drug sensitive plate, but the products in China have certain defects: (1) the culture time of the drug sensitivity test is longer; (2) the growth condition of the microorganism is judged according to the turbidity of the drug sensitivity test result, and the judgment index is not obvious.
The drug sensitive test indicator is a substance which can be added into a drug sensitive test reaction to increase the sensitivity of the drug sensitive test and the convenience of interpretation, does not influence the growth of microorganisms and the drug effect of antibacterial drugs, and can convert turbidity signals generated by the growth of the microorganisms into more easily identified color signals and fluorescence signals, thereby increasing the sensitivity of the drug sensitive test and enabling the signal identification of a drug sensitive reading instrument to be easier.
Disclosure of Invention
The invention aims to solve the problems and provide a method for testing microbial drug sensitivity tests by using a drug sensitivity indicator, which improves the interpretation sensitivity of the drug sensitivity tests and increases the specificity of the interpretation results and can meet the detection requirements of various types of microbial drug sensitivity tests.
The purpose of the invention is realized by the following technical scheme:
a method for detecting drug sensitivity of microorganism by using drug sensitivity indicator comprises using resazurin or its soluble salt as drug sensitivity indicator, and indicating drug sensitivity result of microorganism by color and/or fluorescence signal.
Further, the result of indicating drug sensitivity by color is specifically that if the color of the indicator is red, pink or purple, the indicator represents the growth of microorganisms in the drug sensitivity test, and the antibacterial drug does not work;
if the indicator is blue, bluish purple or purple, it means that the microorganism does not grow in the drug sensitive test, and the antibacterial drug acts.
Further, the indication of the drug sensitivity result through the fluorescence signal is specifically that the indicator is irradiated by excitation light, if a strong fluorescence signal appears, the indicator represents that the microorganism grows in the drug sensitivity test, the antibacterial drug does not act, and if no strong fluorescence signal appears, the indicator represents that the microorganism does not grow in the drug sensitivity test, and the antibacterial drug acts.
Furthermore, the excitation light is the excitation light with the wavelength of 500-540 nm, and the fluorescence signal with the wavelength of 570-620 nm is collected.
Furthermore, the resazurin or the soluble resazurin salt thereof can be coated into a drug sensitive reagent in advance to form one of the components of the drug sensitive reagent, and can also be added in the drug sensitive test process as an independent reagent.
Furthermore, one specific method for coating the resazurin or the soluble resazurin salt thereof into the drug-sensitive reagent in advance to become the component of the drug-sensitive reagent is to directly add the resazurin or the soluble resazurin salt into the drug-sensitive reagent.
Furthermore, the specific method of the resazurin or the soluble resazurin salts thereof as the independent reagent is as follows,
when a drug susceptibility test is carried out, resazurin or soluble resazurin salts are prepared into a solution and added into a drug susceptibility inoculation culture solution;
or in the drug susceptibility test culture stage, preparing the resazurin or soluble resazurin salts into a solution, and adding the solution into a drug susceptibility test reaction hole;
or preparing solution of resazurin or soluble resazurin salt 15 min-2 h before the result of the drug sensitivity test is judged, and adding the solution into the reaction hole of the drug sensitivity test.
Further, the resazurin or the soluble resazurin salt is added in an amount to ensure that the concentration of the resazurin or the soluble resazurin salt is 5 to 100 mu g/mL in a drug sensitivity test.
Further, the microorganism includes, but is not limited to, bacteria and/or fungi.
The invention uses resazurin or its soluble resazurin salt as the indicator of drug sensitive test, which does not affect the growth of microbe and the drug effect of antibacterial drug, and can convert the turbidity signal of microbe growth into more recognizable color signal and fluorescence signal, thus increasing the sensitivity of drug sensitive test and making the signal recognition of drug sensitive reading instrument easier.
After the drug sensitivity indicator is combined with a drug sensitivity test, the sensitivity and the detection time of the drug sensitivity test can be increased, so that the clinical guidance significance is important, and the application value is greater.
The inventor improves the turbidity signal of the traditional turbidimetry, so that the turbidity signal is converted into a color source signal or a fluorescence signal, the detection of an automatic instrument is more convenient, and the detection sensitivity of the instrument is increased.
Compared with a trace broth dilution method provided by CLSI M100, the consistency of the results reaches 95 percent, and the international standard is reached.
Compared with the prior art, the method synchronously judges the survival condition of bacteria by utilizing the color/fluorescence signals, and when a drug sensitivity test is carried out, because the concentration of the antibacterial drug is subjected to gradient dilution, the concentration of partial antibacterial drug is not enough to completely kill microorganisms, so that the indicator presents intermediate purple.
