Description
Technical field
The invention belongs to biomedical diagnostic techniques fields, and in particular to a kind of modified form mycobacterium tuberculosis is quickly antiacid
Fluorescent dyeing reagent.
Background technique
Pulmonary tuberculosis is a kind of common respiratory system communicable disease, spread speed quickly, if failing to receive in time effective
Diagnosis and treatment, it is easy to cause mycobacterium tuberculosis infection other organs or system, such as bone tuberculosis, enteron aisle tuberculosis, kidney tuberculosis,
Not only bring the larger pain of patient, moreover it is possible to improve treatment difficulty, accelerate disease progression, the extended treatment time increases organ function
Failure risk.With the development that deepens continuously of China's medical level, gradually reinforcement to pulmonary tuberculosis prevention and control dynamics, in addition the common people couple
It is gradually increased in what health care required, under comprehensive function, many tuberculars are timely and effectively treated.But according to doctor
Investigation display is learned, lunger's disease incidence is still high, has become whole world public health problem outstanding.
Mycobacterium tuberculosis be elongated slightly curved bacillus, 1~0.4 μm of size.Mycobacterium bovis then compares tubbiness.Point
The bacteria cell wall lipid content of Ramibacterium is higher, accounts for about the 60% of dry weight, especially has a large amount of mycolic acids to be enclosed in peptide poly-
The outside of sugar layer can influence penetrating for dyestuff.Mycobacterium tuberculosis is in vivo and in vitro through penicillin, seromycin or bacteriolyze enzyme induction
The synthesis of peptide glycan in cell wall can be influenced, isoniazid influences the synthesis of mycolic acid, and macrophage swallows mycobacterium tuberculosis
The effect of lysozyme can destroy peptide glycan afterwards, and can lead to it becomes L-type, be in granular form or Filamentous.
It includes that neat-Nissl Ziehi-Neelsen stain, cultivation and auramine O are glimmering that clinic, which is commonly used in the method detected in conjunction with bacillus,
Light decoration method etc..
1. neat-Nissl Ziehi-Neelsen stain: Ziehi-Neelsen stain is a kind of common, easy and rapidly combines bacillus detection side
Method is of great significance to diagnosis lungy.This method is to make mycolic acid secured with carbolfuchsin in a heated condition
It is combined into compound, handles also nondiscoloration with hydrochloride alcohol.After adding alkaline methylene blue to redye again, mycobacteria remains as red,
And the substance in other bacteriums and background is blue.The method is limited by mycobacterium quantity in sputum, and sensibility is low, omission factor
It is high.And life or death bacterium cannot be distinguished in this method, and Mycobacterium tuberculosis and Nontuberculosis mycobacteria especially cannot be distinguished.
2. isolated culture method: obligate aerobic.Optimum temperature is 37 DEG C, is not grown lower than 30 DEG C.Mycobacterium tuberculosis is thin
The lipid content of cell wall is higher, influences the absorption of nutriment, therefore slow growth.In 1 generation of every division, takes in general culture medium
18~24 hours.There are commonly Roche solid mediums, include yolk, glycerol, potato, inorganic salts etc..Yolk is raw containing lipid
The long factor, can stimulating growth.According to how much bacterium is inoculated with, general 2~4 weeks visible colonies are grown.Bacterium colony is in particle, tubercle or cauliflower
Shape, milky or ecru are opaque.Although cultivation high sensitivity but detection cycle is too long, treatment is not only affected adversely, also significantly
Increase pipe be broadcast to others risk.
3. auramine O fluorescence colour: after dyeing and redye by auramine O, with the fluorescence microscopy microscopy containing ultraviolet source
It looks into, acid-fast bacilli is in glassy yellow, and the substance in other bacteriums and background is in dark yellow, and this method can use low power microscopy, because
This can more rapidly find out mycobacteria.There are three types of reagent, three-step approach operations for this method.First step auramine O dyes 15 minutes, rinses
Complete second step pickling 2 minutes has been rinsed third step and has been redyed 2 minutes.Entire dyeing course probably needs 20 minutes.
Summary of the invention
The present invention develops a kind of double-formulation in view of the shortcomings of the prior art, carry out improvement optimization to auramine O fluorescence colour
The quick antiacid fluorescent dyeing reagent of mycobacterium tuberculosis.Product of the present invention stability is good, two kinds of reagents, only needs two steps to operate and is
Achievable dyeing, and dyeing time was reduced to 2 minutes or so by traditional 20 minutes, clinical use is more convenient, quick, significantly
Improve the detection efficiency of mycobacterium tuberculosis.
Specific technical solution of the present invention is as follows:
The quick antiacid fluorescent dyeing reagent of a kind of modified form mycobacterium tuberculosis, it is characterised in that including two kinds of reagent A liquid and B
Liquid.A liquid includes water, salt, chaotropic agent, moisturizer, fluorescein.B liquid includes water, acid, alcohol, counterstain.
Salt described in A liquid of the present invention is inorganic salts, preferably potassium chloride or sodium chloride.It is preferred that the concentration of alkali is 0.5%-1.0%(W/
V), more preferable 0.9%(W/V).
Chaotropic agent described in A liquid of the present invention is selected from water-miscible organic solvent, preferably dimethyl sulfoxide.The effect of chaotropic agent is dye
The solubility and stability of material.It is preferred that the concentration of chaotropic agent is 15-25%(V/V).
Moisturizer described in A liquid of the present invention is selected from glycerol, propylene glycol, one or more of butanediol, preferably glycerine.Moisturizing
The effect of agent is to increase solution entirety moisturizing degree and diopter, is intensified, so that dyeing is relatively sharp.It is preferred that moisturizing
The concentration of agent is 10-30%(V/V).
Fluorescein described in A liquid of the present invention is selected from acid resistant form fluorescent dye, preferably auramine O, preferred concentration 0.1-0.3%(W/
V).
The acid described in B liquid of the present invention is selected from inorganic acid, preferably hydrochloric acid.Hydrochloric acid plays the decolorization after dyeing, tuberculosis point
Branch bacillus is not decolourized due to antiacid characteristic.It is preferred that the concentration of hydrochloric acid is 0.3-0.5%(V/V).
The alcohol described in B liquid of the present invention is selected from monohydric alcohol, preferred alcohol.Preferred concentration is 70-75%(V/V).
