Technical Field
The application relates to the technical field of microorganisms, in particular to lactobacillus reuteri with a function of improving colpitis and application thereof.
Background
Vaginitis (Vaginitis), a group of conditions that lead to vulvovaginal symptoms such as itching, burning, irritation and abnormal fluid flow. The vagina of a normal healthy woman has natural defensive function against pathogen invasion due to the characteristics of anatomical tissues. Clinically, there are common: bacterial vaginosis, candidal vaginitis, trichomonas vaginitis, senile vaginitis, and juvenile vaginitis.
Bacterial Vaginitis (BV) is a syndrome of increased vaginal secretion caused by mixed infection of gardnerella vaginalis and anaerobic bacteria, which results in imbalance of microecological balance in vagina, and white with fishy smell and pruritus vulvae. Bacterial vaginitis is classified into haemophilus vaginitis, corynebacterium vaginitis, anaerobic vaginitis, gardnerella vaginitis, etc.
Currently, attempts are made to treat the affected area with oral or direct administration of antibiotics, antifungals or combinations, depending on the cause of the infection. In infectious vaginitis, gardnerella vaginalis and candida albicans are main microorganisms causing vaginitis, and after the pathogenic bacteria are infected, excessive antibiotics, stress, primary vaginitis caused by intrinsic factors and the like are caused, the amount of lactobacillus capable of generating hydrogen peroxide in the vagina is reduced, the direct sterilization effect of the hydrogen peroxide is reduced, and the lactic acid production amount is reduced, so that the pH value is increased, and various bacteria are easy to grow. Therefore, providing a lactic acid bacterium that inhibits the growth of pathogenic bacteria and that has a high hydrogen peroxide yield can play an important role in improving female reproductive health.
Disclosure of Invention
The application aims to provide lactobacillus reuteri capable of improving colpitis and application thereof, wherein the lactobacillus reuteri has a certain antibacterial effect on gardnerella vaginalis, staphylococcus aureus and candida albicans, and meanwhile, hydrogen peroxide can be produced at high yield, so that the lactobacillus reuteri can improve colpitis caused by microbial infection.
In order to achieve the above object of the present application, the following technical solutions are specifically adopted:
in a first aspect the present application provides a lactobacillus reuteri, in particular lactobacillus reuteri (Limosilactobacillus reuteri) HR7, deposited with the cantonese collection of microbial strains under accession number GDMCC No:63350, the preservation time is 2023, 04 and 14.
In a second aspect, the application provides a microbial preparation comprising said lactobacillus reuteri.
In a third aspect the application provides a metagen of the above lactobacillus reuteri.
In a fourth aspect, the present application provides the use of at least one of said lactobacillus reuteri, said microbial agent and said metazoan for the manufacture of a vaginal care product.
The fourth aspect of the application provides an application of at least one of lactobacillus reuteri, the microbial preparation and the metazoan in preparing medicines or foods for preventing and treating colpitis.
Preferably, the vaginitis is vaginitis caused by at least one of candida albicans, staphylococcus aureus and gardnerella vaginalis.
Preferably, the pharmaceutical dosage forms include lotions, gels and ointments.
In a fifth aspect, the present application provides a medicament for preventing and treating vaginitis, the medicament comprising at least one of the lactobacillus reuteri, the microbial preparation and the metazoan, and pharmaceutically acceptable auxiliary materials.
Preferably, the pharmaceutical dosage forms include lotions, gels and ointments.
Preferably, the content of lactobacillus reuteri in the medicament is 10 6 ~10 10 cfu/ml, the content of metazoan is 10-100 mg/g.
Compared with the prior art, the application has the beneficial effects that at least:
the lactobacillus reuteri has certain antibacterial effect on gardnerella vaginalis, staphylococcus aureus and candida albicans, and can produce hydrogen peroxide at high yield, so that the lactobacillus reuteri can improve colpitis caused by microbial infection; therefore, the lactobacillus reuteri can be used for preparing vaginal care products and medicines for preventing and treating vaginitis, can establish a vaginal microecological barrier and delay genital tract aging, and provides powerful guarantee for female reproductive health.

morphological characterization of strain HR7 was characterized as follows: the bacillus-free bacteria which are gram-positive are streaked on MRS culture medium to form obvious bacterial colony after 48 hours of culture, the diameter is between 0.2 and 2.5mm, and the bacillus-free bacteria are round, slightly white, convex and opaque.
The screened strain HR7 is determined to be lactobacillus reuteri HR7 through the alignment of the 16S rRNA and morphological characteristics.
Example 3
This example shows the inhibition of the above-mentioned Lactobacillus reuteri HR7 against Gardnerella vaginalis (KCTC 5096), candida albicans (KCTC 7678) and Staphylococcus aureus (ATCC 25923):
activating lactobacillus reuteri HR7, inoculating into MRS liquid culture medium, and culturing to obtain 1×10 concentration 8 cfu/ml of culture solution;

will be 1X 10 8 3 parts of cfu/ml of lactobacillus reuteri HR7 culture solution are taken, and each part is 3ml;
the concentration is 1 multiplied by 10 8 2 parts of culture solution of gardnerella vaginalis, candida albicans and staphylococcus aureus are respectively taken from cfu/ml, wherein 1 part of culture solution is 3ml in volume, and the other part of culture solution is 6ml;
mixing 3 parts of lactobacillus reuteri HR7 culture solution with 3ml of gardnerella vaginalis, candida albicans and staphylococcus aureus culture solution respectively, and sequentially marking as an experiment 1 group, an experiment 2 group and an experiment 3 group respectively, wherein the rest 3 parts of gardnerella vaginalis, candida albicans and staphylococcus aureus culture solution sequentially serve as a control group, and sequentially marking as a control 1 group, a control 2 group and a control 3 group;
respectively inoculating the experiment 1 group, the experiment 2 group, the experiment 3 group, the control 1 group, the control 2 group and the control 3 group into MRS liquid culture medium for culturing for 20 hours to obtain culture solutions respectively;
100. Mu.l of each of the above-mentioned different media was inoculated into 20ml of a selective medium of Gardnerella vaginalis, candida albicans and Staphylococcus aureus, and then, gardnerella vaginalis, candida albicans and Staphylococcus aureus were counted, and the counting results are shown in Table 1;
TABLE 1
As shown in Table 1, the Lactobacillus reuteri HR7 of the present application has excellent inhibitory effect on Gardnerella vaginalis, candida albicans and Staphylococcus aureus.
Example 4
The experimental study of the hydrogen peroxide production performance of lactobacillus reuteri HR7 is shown in the example:
the mass fraction of H was 30% using 100mmol/L piperazine-N, N' -di-ethane sulfonic acid (PIPES) 2 O 2 Diluted to 1mol/L and 1mol/L H with 100mmol/L PIPES 2 O 2 Diluting into 0 mu mol/L, 20 mu mol/L, 40 mu mol/L, 60 mu mol/L, 80 mu mol/L and 100 mu mol/L solutions respectively; then 100. Mu.L of the above H was taken separately 2 O 2 Mixing the solution with 100 mu L of 20mmol/L TMB, adding 2 mu L of horseradish peroxidase (1 mg/mL) into the mixed solution, uniformly mixing, incubating at 16 ℃ for 10min, measuring OD600 and drawing a standard curve;
