Problems solved by technology

Mycoplasma research in my country, especially the research on the experimental diagnosis of pathogenic mycoplasma, started late, the method is backward, and because of the low positive rate of mycoplasma culture and the contamination of miscellaneous bacteria, it is prone to false positives and many other problems, so it cannot be widely used in clinical diagnosis.
For the cultivation and separation of mycoplasma abroad, there are commercialized Difco, Oxoid dry base, and the finished

Example Embodiment

[0023] Example 1

[0024] A liquid-solid combined culture kit for urealytic and Mycoplasma hominis separation culture, identification, quantification and drug sensitivity test, including drug sensitivity and quantitative test strips, transparent sealing film, bottled liquid medium, and slatted solid phase culture The medium is light yellow, transparent, clear liquid or solid, and its component formula is as follows:

[0025] Base 700ml,

[0026] 200ml horse (or bovine) serum,

[0027] 25% yeast extract 100ml,

[0028] 40% urea 15ml,

[0029] 30% L-arginine 33ml,

[0030] 0.4% phenol red 5ml,

[0031] 10000IU / ml penicillin 50ml,

[0032] The formula of the basic base contains 50g of beef heart powder, 10g of peptone, and 5g of NaCl per 1000ml of the base. Adjust the pH to 6.0 in the 1000ml medium, and add 10-12g agar powder to the solid phase medium;

[0033] The drug sensitivity and quantitative test strip has 26 small holes: C+ hole is a positive control hole, C- hole is a negati...

[0037] Example 2

[0038]An application method of a liquid-solid combined culture kit for urealytic and Mycoplasma hominis separation culture, identification, quantification and drug sensitivity test, the method includes the following steps:

[0039] (1) Take the specimen to be inspected: such as urethral secretions with a sterile cotton swab, and semen with a dropper;

[0040] (2) Inoculate the specimens to be inspected on liquid medium and solid medium by conventional methods: for example, liquid specimens are directly added to liquid medium and smeared on the surface of solid medium;

[0041] (3) Use a dropper to suck up 0.1ml of standard cultures of Ureaplasma urealyticum and Mycoplasma hominis and add them to well C+ of the drug susceptibility and quantitative test strip. Take 0.1ml of liquid culture medium and add it to well C-, and take samples with specimens to be tested. Add 0.1ml of liquid-phase culture medium to Uu holes, Mh holes, and drug sensitivity test holes, seal ...

Example Embodiment

[0047] Example 3

[0048] A growth performance test method:

[0049] Strain: Mycoplasma hominis (ATCC 23114) 37℃24h culture,

[0050] Ureaplasma urealyticum (ATCC 27618) 37℃24h culture,

[0051] Equipment: incubator (36℃±1℃), sterile straw

[0052] Steps: (1) Take the tested medium,

[0053] (2) Use a sterile straw to suck up 0.1ml of the above-mentioned cultures of Mycoplasma hominis and Ureaplasma urealyticum, add them to the liquid and solid medium, and then place them in an incubator (36°C±1°C) for cultivation.

[0054] (3) Culture of Mycoplasma hominis for 48h and Ureaplasma urealyticum for 24h, and take out the observation results.

Abstract

The invention relates to a liquid-solid combined culture kit for isolation and culture, identification, ration and drug sensitive tests of antiureal and mycoplasma hominis and an application method. The kit comprises drug sensitive laths and quantitative test laths, a liquid medium and a solid medium; the liquid medium and the solid medium are both weakly acidic, with a PH value about 6.0. Compared with the prior art, the liquid-solid combined culture kit for isolation and culture, identification, ration and drug sensitive tests of antiureal and mycoplasma hominis has the advantages of easy operation, reliable method, stable quality, easy observation and judgment of results and other advantages; meanwhile, the liquid-solid combined culture kit has good specificity and sensitivity, the liquid-solid combined kit can reduce the false positive rate by 5% to 10% or so, and the false negative rate by 2% to 5% or so; the liquid-solid combined culture kit basically eliminates the problem of the test result disturbances from the mixed fungi pollution, and has an important practical application value and a good market prospect.

Description

technical field [0001] The invention relates to a kit for biomedicine, in particular to a liquid-solid combined culture kit for separation and cultivation, identification, quantification and drug sensitivity test of urealyticum and mycoplasma hominis and an application method thereof. Background technique [0002] Mycoplasma is a kind of prokaryotic microorganism lacking cell wall, and more than 150 kinds of mycoplasma have been isolated so far. The mycoplasmas related to human diseases are mainly Ureaplasma urealyticum (hereinafter referred to as Uu), Mycoplasma hominis (hereinafter referred to as Mh) and Mycoplasma pneumoniae (Mycoplasma pneumoniae, Mp), among which Uu and Mh are recognized internationally as the cause of Pathogens of Genitourinary Tract Infection (Cao Yupu, edited by Ye Yuankang, Mycoplasma and Mycoplasma Disease, Beijing: People's Health Publishing House, 2000, 5). Mycoplasma research in my country, especially the research on the experimental diagnosis ...
