The invention discloses a test strip that is used for detecting antibodies of porcine parvovirus and porcine encephalitis B virus in one step, which comprises a supporting layer, an adsorptive layer and a protecting layer, and the adsorptive layer consists of a sample fiber layer, an adsorptive gold mark fiber layer, a fibrin membranous layer and a water absorptive material layer sequentially from a testing end; the adsorptive gold mark fiber layer adsorbs any one or two from antigen liquids of gold colloid marked SPA or gold colloid marked pure PPV and JEV; a detecting print and a contrast print are arranged on the fibrin membranous layer, the detecting print is printed with any one or two from the purified PPV and JEV antigen liquids, and the contrast print is printed with an IgG solution of ovine or rabbit anti-SPA or an IgG solution of any one or two viruses from ovine or rabbit anti-PPV and anti-JEV. The test strip of the invention has strong detecting specificity and high sensitivity, avoids additional equipment and reagents, can be operated by every person, and is particularly applicable to the quick specific antibody detection of porcine diseases on the spot.

The invention discloses a test reagent for realizing the online rapid nondestructive test of the quality of a gold plating layer and a using method of the test reagent. The reagent contains trifluoroacetic acid and copper sulfate pentahydrate. The using method comprises the following steps: dropwise adding 2-3 drops of test reagent in a to-be-detected region of the gold plating layer, wiping the gold plating layer by using dust-free cloth after 60-120s, and observing the color change condition of the gold plating layer; if the color of the gold plating layer is changed, judging that a workpiece is a defective product; if the color of the gold plating layer is unchanged, judging that the plating layer is qualified. The test reagent disclosed by the invention is rapid in reaction, an obvious color difference exists between a generated corrosion product and the plating layer, and a result is high in accuracy and easy to judge; the test reagent is extremely simple in operation, no special instruments are needed, and online detection can be realized; the test reagent can be used for realizing nondestructive test, and workpieces which are qualified through test can be continued to be processed, assembled and circulated on a production line, so that the resource is saved; the test reagent is low in cost but capable of accurately reminding a manufacturer of stopping the subsequent processing of a defective product of the plating layer and taking remediation measures in time, so that more loss is avoided.

The test strip for fast detecting colibacillus O157:H7 antigen belongs to the field of medical diagnosis article technology. The fast test strip includes one base substrate, one fiber film covering the base substrate, one water absorbing film covering the upper part of the base substrate, monoclonal marking antibody of colibacillus O157:H7 antigen adsorbed onto the fiber film in the lower part of the test strip, one anti-mouse IgG coated quality controlling line on the middle part of the fiber film, and one detecting line coated with monoclonal antibody of colibacillus O157:H7 antigen with excellent pairing property to absorbed marking antibody below the quality controlling line. The marking antibody has marker of colloidal gold, the concentration of colloidal gold antibody is (1.0-3.0)x10<->3 mg / sq cm, and that of the coating antibody is (2.0-8.0)x10<->4 mg / sq cm. The present invention has high detection speed and high detection accuracy.

The invention provides an eye fundus image judgment method and eye fundus image judgment equipment. The eye fundus image judgment method comprises the following steps: acquiring a to-be-judged eye fundus image of a user; Obtaining a reference fundus image associated with the fundus image to be judged, wherein the reference fundus image is a fundus image with a known state being normal; Generatinga difference image according to the to-be-judged fundus image and the reference fundus image; And taking the differential image as input data of a machine learning model, enabling the machine learningmodel to output a judgment result of the to-be-judged fundus image, and training the machine learning model by using the training differential image and corresponding label data.

The invention discloses an LAMP primer of staphylococcus aureus. The LAMP primer comprises two inner primers (FIP and BIP) and two outer primers (F3 and B3), namely, F3 as shown in the sequence SEQ ID NO:1, B3 as shown in the sequence SEQ ID NO:2, FIP as shown in the sequence SEQ ID NO:3 and BIP as shown in the sequence SEQ ID NO:4. Aiming at the specific nuc gene of the staphylococcus aureus, a group of primers is designed, and a sensitive and specific staphylococcus aureus LAMP detection method is established by using the primers. The experiment shows that the detection sensitivity and the detection limit of the LAMP detection method are 100 times of those of a PCR method; whether green fluorescence is generated or not can be observed with naked eyes so as to confirm whether the reaction is performed, so that the result judgment can be simple, convenient and feasible; compared with a PCR technique, the method disclosed by the invention has the advantages that the time and the labor can be saved, no expensive instruments or tedious electrophoretic analysis is needed, and the application method disclosed by the invention is particularly applicable to use in base levels.

The invention discloses an IgM antibody detection agent for toxoplasma, wherein it uses anti-human IgM-mu chain mono-clone antibody to pack the micro-pore plate, marking with the toxoplasma antigen and enzyme-label antigen for toxoplasma antigen and other assist agents to prepare the detection agent. This invention has high sensitivity and well specificity fit to convenient operation.
