Description
The application is filed on 2016, 8 months and 30 days, has an application number of 201610780447.4 and is named as follows: the divisional application of the Chinese patent application of 'method for rapidly detecting vibrio parahaemolyticus at constant temperature, primers and application'; the parent application claims the priority of the Chinese patent application with the application date of 2015, 9 and 2, the application number of 201510556917.4, entitled 'method, primer and kit for rapid constant temperature detection of cronobacter sakazakii'.
Technical Field
The invention belongs to the technical field of biology, and particularly relates to a method, primers and a kit for rapidly detecting vibrio parahaemolyticus at constant temperature.
Background
Vibrio parahaemolyticus (Vibrio parahaemolyticus) is a gram-negative halophilic bacterium, widely distributed in rivers, oceans, tropical zones and coastal areas of temperate zones, and mainly parasitizes in aquatic products such as plankton, fish, shrimp, crab, shellfish and the like, and when directly or indirectly eating food polluted by the bacterium, the typical gastroenteritis reactions such as diarrhea, intestinal spasm, nausea, vomiting, fever and the like can be caused, and septicemia can be caused by severe cases. The incidence of vibrio parahaemolyticus is distributed worldwide, particularly, the incidence rate in coastal areas is high, and the food poisoning caused by vibrio parahaemolyticus in coastal cities in China accounts for a higher proportion than salmonella, escherichia coli O157: H7, staphylococcus aureus and the like in bacterial food poisoning events and is the top. Therefore, the method has important significance for the detection and prevention of the bacteria.
At present, the detection method for vibrio parahaemolyticus at home and abroad still uses a conventional culture method as a standard, the detection period is longer (up to 5-7 days), the operation is relatively complex, the detection efficiency is lower, and the requirements of high flux, high sensitivity, high specificity, rapidness and convenience in the detection process of food-borne pathogenic bacteria in modern society are difficult to meet. With the development of nucleic acid molecule detection technology in recent years, PCR technology established by taking specific genes as targets has been successfully applied to the detection of Vibrio parahaemolyticus, and has the advantages of high sensitivity, short detection time and the like, but the method must be equipped with special instruments and equipment, and needs professional operators. Therefore, the method is not suitable for being widely applied to real-time field detection in basic detection departments, particularly in enterprise production lines. In order to ensure the safety of food, a rapid, simple and accurate method for detecting vibrio parahaemolyticus in food is urgently needed.
Loop-mediated isothermal amplification (LAMP) is a novel isothermal Nucleic acid amplification method developed in recent years, which designs 4 specific primers (including upstream and downstream outer primers F3 and B3, and upstream and downstream inner primers FIP and BIP, wherein FIP is composed of F1C and F2, BIP is composed of B1C and B2), and performs Nucleic acid amplification reaction by incubating for about 60min at an isothermal condition, to generate a macroscopic reaction byproduct, namely white magnesium pyrophosphate precipitate (see Notomi T, Oyama H, Masubuchi H, Yonekawa T, Watanabe K, Nuino N, Hase.loop-mediated isothermal amplification DNA, Research, Jeans, 2000, J3828; 63E, 15, J3828, 63). The technology can be completed under constant temperature without a PCR instrument or a fluorescent quantitative PCR instrument, can judge the reaction result by naked eyes, and has the advantages of high sensitivity, strong specificity, short reaction time, convenient operation, low cost and the like.
Primer design is the most critical step in LAMP technology, and the conventional method is to introduce the acknowledged specific gene of a certain organism to be detected into an online website (http:// primer explorer. jp/e) designed by LAMP primers, and set relevant parameters to generate a primer group. That is, the user must first ensure that the target gene is a specific sequence for the species being tested. The invention discloses a method for detecting vibrio parahaemolyticus by LAMP technology, which is used for detecting vibrio parahaemolyticus by taking patents ZL201210062791.1 and CN 104513857A as examples and aiming at tlh and irgB sequences which are specific genes of vibrio parahaemolyticus and are reported in documents. However, the so-called "recognized specific genes" are often based on a delayed knowledge and are not necessarily updated based on the ever-increasing genome data of microorganisms, so that primers obtained based on the target gene sequences are not necessarily able to ensure their versatility and/or specificity in practical applications. The present invention is shown in Table 1, which shows the problem of the prior art that the primer versatility cannot be ensured. That is, the Vibrio parahaemolyticus detection sequence used in the prior art method is not actually common to Vibrio parahaemolyticus, i.e., there is a possibility that a partial strain of Vibrio parahaemolyticus may be missed. A similar problem exists in the confirmation of specificity, i.e., there is a possibility that non-vibrio parahaemolyticus is erroneously recognized as vibrio parahaemolyticus. Therefore, a vibrio parahaemolyticus detection method capable of ensuring specificity and universality is urgently needed in the industry, and meanwhile, the requirements of the basic detection department on rapidness and convenience are met, and real-time on-site detection can be conveniently developed in the production line of an enterprise.

In the method, the reaction procedure of the isothermal amplification reaction is incubation for 10-90 min at 60-65 ℃, preferably 10-60 min; ② terminating the reaction for 2-20 min at 80 ℃. The invention is not limited to the implementation of the detection method of the invention by other suitable reaction procedures.
In the method of the present invention, the detection method includes, but is not limited to, electrophoresis detection, turbidity detection, or color development detection. The electrophoresis detection is preferably a gel electrophoresis detection method, and can be agarose gel or polyacrylamide gel. In the electrophoresis detection result, if the electrophoretogram shows a characteristic step-shaped strip, the sample to be detected is positive for vibrio parahaemolyticus and contains vibrio parahaemolyticus; if the electrophoretogram does not present a characteristic ladder-shaped strip, the sample to be detected is negative to vibrio parahaemolyticus. The turbidity detection is to detect turbidity by visual observation or a turbidity meter, and if the detection tube is obviously turbid, the sample to be detected is positive to the vibrio parahaemolyticus and contains the vibrio parahaemolyticus; if no turbidity is found, the sample to be tested is negative to vibrio parahaemolyticus. Or the reaction tube bottom can be observed by naked eyes after centrifugation to see whether the sediment exists or not, if the sediment exists at the reaction tube bottom, the sample to be detected is positive to the vibrio parahaemolyticus and contains the vibrio parahaemolyticus; if no precipitate is formed at the bottom of the reaction tube, the sample to be detected is negative to vibrio parahaemolyticus.
The color development detection is to add color development reagent, including but not limited to calcein (50 μ M) or SYBR Green I (30-50 ×), or hydroxynaphthol blue (i.e. HNB, 120-. When calcein or SYBR Green I is used as a color developing agent, if the color is orange after reaction, the sample to be detected is negative to vibrio parahaemolyticus; if the color after the reaction is green, the sample to be tested is positive for vibrio parahaemolyticus and contains vibrio parahaemolyticus. When hydroxynaphthol blue is used as a color developing agent, if the color after the reaction is violet, the sample to be detected is negative to vibrio parahaemolyticus; if the color after the reaction is sky blue, the sample to be detected is positive for vibrio parahaemolyticus. The chromogenic detection can be used for detecting the reaction result in real time or at the end point through a detection instrument besides observing the reaction result through naked eyes, and by reasonably setting the threshold value of the negative reaction, when the reaction result of the sample to be detected is lower than or equal to the threshold value, the sample to be detected is negative to vibrio parahaemolyticus; and when the reaction result of the sample to be detected is greater than the threshold value, the sample to be detected is positive for the vibrio parahaemolyticus. The detection instrument comprises but is not limited to a fluorescence spectrophotometer, a fluorescence quantitative PCR instrument, a constant temperature amplification microfluidic chip nucleic acid analyzer, a Genie II isothermal amplification fluorescence detection system and the like.
In the color development detection, if calcein or hydroxynaphthol blue is used as a color developing agent, the color developing agent can be added before the isothermal amplification reaction, or can be added after the isothermal amplification reaction is completed, preferably before the isothermal amplification reaction, so that the possibility of reaction pollution can be effectively reduced. If SYBR Green I is adopted as the color developing agent, the SYBR Green I is added after the isothermal amplification reaction is finished. If calcein is used as color-developing agent, 50 μ M calcein is added into enzyme reaction system, and 0.6-1mM [ Mn ] is added2+]For example, 0.6-1mM of MnCl2。

Detailed Description
The present invention will be described in further detail with reference to the following specific examples and drawings, but the present invention is not limited to the following examples. Variations and advantages that may occur to those skilled in the art are intended to be included within the invention without departing from the spirit and scope of the inventive concept, and the scope of the invention is to be determined by the appended claims. The procedures, conditions, reagents, experimental methods and the like for carrying out the present invention are general knowledge and common general knowledge in the art, except for the contents specifically mentioned below, and the present invention is not particularly limited.
Examples 1-6 Vibrio parahaemolyticus isothermal reaction System and detection method
The detection is carried out according to the following steps (1) to (3):
(1) extraction of genomic DNA
The vibrio parahaemolyticus strain for detection is from China general microbiological culture collection center with the number of CGMCC 1.1997 (ATCC 17802). 1mL of the bacterial culture was used to extract genomic DNA and DNA OD using a bacterial nucleic acid extraction kit from Beijing Tiangen bioengineering Co260/OD280At a concentration of 1.8, 216 ng/. mu.L.
(2) Taking the genome DNA of vibrio parahaemolyticus to be detected as a template, respectively adopting self-prepared kits (shown in table 2 and table 3), preparing a reaction system according to the conditions in table 3, and taking a specific amplification primer group of the vibrio parahaemolyticus as a primer to carry out constant-temperature amplification reaction. The primers used in examples 1 to 6 were primer sets A, A ', B, C, D', respectively.
(3) The amplification results were confirmed by electrophoresis, turbidity or color development under the conditions shown in Table 3.
As can be seen from Table 3, the detection method and the primer set and the reaction system adopted by the detection method can well amplify the specific segment of the vibrio parahaemolyticus and obtain the detection result. In addition, when the detection is performed by using a detector, the detection effect is good when the reaction time is shortened to 10min (as in example 6). Therefore, the present invention can be applied to the detection of whether or not a sample contains Vibrio parahaemolyticus.
According to the method of the above embodiment, the specific fragment of Vibrio parahaemolyticus can also be amplified and detected with the primer set D and the primer set B', respectively.
Example 7 Vibrio parahaemolyticus-specific detection
28 strains of non-Vibrio parahaemolyticus (1 to 26, 28 to 29 in Table 4 and FIG. 1) were collected, and these strains were cultured separately from the Vibrio parahaemolyticus (27 in Table 4 and FIG. 1), 1mL of the bacterial solution was taken, and bacterial DNA was extracted using kit IA, and LAMP amplification (primer set A) and visualization by addition of a color developer were carried out separately with reference to the reaction system and conditions of example 1.
The detection results are shown in Table 4 and FIG. 1, in FIG. 1, 1-26 are Staphylococcus aureus, Staphylococcus aureus Chryseozoea, Staphylococcus epidermidis, Rhodococcus equi, Bacillus cereus, Bacillus mycoides, Listeria monocytogenes, Listeria Ennok, Listeria Israeli, Salmonella enterica, Salmonella typhimurium, Salmonella paratyphi B, Shigella dysenteriae, Shigella boydii, Shigella flexneri, Escherichia coli (containing Clostridium botulinum type A gene), pathogenic Escherichia coli, Escherichia coli diarrheal, enterotoxigenic Escherichia coli, Escherichia enterohemorrhagic, Cronobacter sakazakii, Yersinia enterocolitica, Escherichia pseudotuberculosis, Vibrio vulnificus, Vibrio paravibrio haemolyticus, 28-29 are vibrio freundii and vibrio cholerae respectively, NTC: negative control, 27: vibrio parahaemolyticus. In FIG. 1, the product obtained after the amplification reaction of only the Vibrio parahaemolyticus strain appeared in a bright green color as a positive result, as shown in tube 27. The products of the other non-Vibrio parahaemolyticus strains and the negative control amplification reaction are orange, and are negative results, as shown in tubes No. 1 to 26, tubes No. 28 to 29 and NTC negative control tube.
As can be seen from the results of FIG. 1 and Table 4, the detection kit and the detection method of the present invention have good specificity of Vibrio parahaemolyticus strains, i.e., only Vibrio parahaemolyticus strains are amplified positively, and other non-Vibrio parahaemolyticus strains are negative.
Preparing a detection kit, wherein the primers adopted in the kit are respectively primer groups B-D, and the primer groups A ', B ' and D ' respectively obtain the same detection results according to the specific detection method, namely, the products after the amplification reaction of the non-vibrio parahaemolyticus strains and the negative control are negative results, and the products after the amplification reaction of the vibrio parahaemolyticus strains are positive results.
In addition, theoretical analysis was performed on the specificity of the primer sets A to D and the primer sets A ', B ', D ' according to the method described in Table 1, and as a result, it was found that, when at most three mismatches were allowed for each primer, at most two primers were simultaneously aligned to Vibrio parahaemolyticus in each primer set, indicating that the specificity of each primer set was better.
Example 8 sensitivity detection
DNA of the bacterium CGMCC 1.1997 was extracted by the method of example 1, and the DNA was added to the reaction system using kit IB in a gradient of 50ng, 5ng, 500pg, 50pg, 5pg, 500fg and 50fg DNA, and LAMP amplification (primer set A) and visualization by adding color developing agent were carried out respectively under the other reaction conditions according to the method of example 1 of Table 3. As shown in fig. 2, 1 to 7 are 50ng, 5ng, 500pg, 50pg, 5pg, 500fg and 50fg, respectively, NTC: and (5) negative control. In FIG. 2, the reaction products of 50ng, 5ng, 500pg, 50pg and 5pg treatments appeared bright green and as positive results, the reaction products of 500fg, 50fg treatments and negative control appeared orange and as negative results. The results of the tests showed that a minimum of 5pg (corresponding to about 900 bacteria) of DNA was still detected in each reaction tube.
According to the detection method, other steps and conditions are the same, and DNA as low as 5pg to 500fg in each reaction tube can still be detected by using the primer group B, the primer groups C to D and the primer groups A ', B ' and D ', respectively.
Example 9 commonality testing
Theoretical analysis of the versatility of the primer sets A to B, C to D, and A ', B ', D ' was carried out according to the method described in Table 1, and it was found that the primer regions of the primer sets completely match the genomic sequences of the second chromosomes (GI Nos. 28899855, 433659170, 525847173, and 525852846) of four Vibrio parahaemolyticus strains, and that the primers were theoretically usable for the detection of the four Vibrio parahaemolyticus strains, indicating that the versatility of the primer sets was good.
TABLE 1 analysis of the universality and specificity of primers in the existing detection method of Vibrio parahaemolyticus
Note: a) each Vibrio parahaemolyticus strain has two chromosomes, and the position of the detection region in the genome of GI No. 28896774#1/28899855#2 is determined by Bowtie alignment of the sequence between primers F3 and B3 with the 8 genomic sequences of the four strains of Vibrio parahaemolyticus, #1 represents the genomic sequence of the first chromosome of the strain, and #2 represents the genomic sequence of the second chromosome of the strain. b) The sequences of the detection regions are subjected to Blast comparison in public database resources, and the primer regions are completely matched, so that the universality is good. c) The sequences of the detection regions are subjected to Blast comparison in public database resources, and primers cannot be simultaneously compared with the sequences of non-vibrio parahaemolyticus, thereby indicating that the specificity of the primers is good.
