Description
Technical field
The present invention relates to microorganism field is and in particular to one plant of Lactobacillus Jensenii and its application.
Background technology
Urogenital infections are that women is most commonly seen but be not affected by the frequently-occurring disease paid attention to, and the incidence of disease is only second to respiratory tract
Infection, may be up to 40%；Female urogenital tract infection is urinary tract infections and the general name of RTI, and it not only directly affects
The physical and mental health of women, and numerous family's wellbeings can be affected and stablize, and then affect quality of the people and the warp of the whole society
Ji development.The common cause of disease of women urinary tract infections is gram-Negative bacillus, wherein common with EHEC, staphylococcus
Take second place；These majorities are the normal flora on human body intestinal canal and skin and mucosa, and because immunity of organisms declines, these bacteriums can be by
The enteron aisle and position of living away from home such as mucocutaneous migrates to urinary system and amount reproduction causes urinary tract infections.The common genital tract of women
Pathogenic infection includes trichomonad, mould and Chlamydia etc., and RTI is the overwhelming majority first per vaginam infect and rise；Because of protracted inflammation
Diffusion can cause pelvic infecton, and leads to infertility.Urogenital infections are " little disease, burdens ", also can increase AIDS
Danger with venereal diseases such as gonorrhoeas；Patients ' life quality is decreased obviously, and mental burden is very heavy.Gravid woman may occur in which a series of gestation
Complication, the such as Averse pregnancy outcomes such as premature labor and chorioamnionitis；Also neonate can be directly made to be subject to by birth canal during childbirth similar
Pathogenic infection and cause a disease.
At present, the treatment of urogenital infections relies primarily on various antibiotic, but therapeutic effect is not good, and cure rate exists
Less than 40%, and the ratio recurring is very high, up to more than 40%.Reason is mainly drug resistance pathogen in Patients with Female Genital
Exist and cause antibiotic to lose efficacy；Even if in addition, antibiotic therapy can kill pathogen, but also kill beneficial bacterium (benefit simultaneously
Raw bacterium), accordingly, it is difficult to the urogenital tract dominant microflora under state of getting well.
There is substantial amounts of bacterium in healthy women of reproductive age urogenital tract, be generically and collectively referred to as urogenital tract flora, wherein wrap
Include multiple different types of bacteriums, " beneficial bacterium " and " pathogenic bacteria " two big class can be roughly classified into, wherein Bacillus acidi lactici is to maintain to secrete
The urodaeum most common and most important beneficial bacterium (" just bacterium ") of health, EHEC, staphylococcus, trichomonad, mould and
Chlamydia is then pathogenic bacteria (" evil bacterium ").Some factors lead to a certain pathogenic bacteria abnormality proliferation, cause urogenital tract sense
Dye.The change of vagina bacterial species is closely related with the health of women and fetus, lactobacillus curvatus therein and Zhan Shi breast bar
Bacterium is the main advantage " just bacterium " maintaining vaginal health micro-ecological environment, can account for healthy urogenital tract flora bacteria total amount
More than 90%.They mainly pass through to suppress the growth of external pathogen and other conditions pathogenic bacteria (" evil bacterium ") and invade
Maintain urogenital tract flora health environment, " just bacterium (beneficial bacterium) " defeat the mechanism of action of " evil bacterium " mainly include with
Lower several respects: the glycogen that (1) passes through to decompose storage in vaginal mucosa epithelium produces the acidic materials such as lactic acid, acetic acid, maintains vagina
Sour environment, with suppress pathogen growth；(2) produce multiple antibacterial substance such as hydrogen peroxide and lactein, in order to
Kill the pathogen of invasion；(3) Bacillus acidi lactici class beneficial bacterium is by, after the field planting of vaginal mucosa epithelium, forming and first impressions are strongest
Occupy-place protective effect, stops the invasion of pathogenic microorganism.
The women of child-bearing age increased with the age, and vagina lactobacillus curvatus or Lactobacillus Jensenii quantity can gradually decrease.Post menopausal,
Ovarian estrogen secretion tapers off, and vaginal epithelial cell glycogen deposit lacks, and vagina ph rises, and lactobacillus curvatus or Zhan Shi are newborn
Bacillus can reduce further, pathogenic bacteria thus increase.So lactobacillus curvatus or Lactobacillus Jensenii give birth to the uropoiesis of elderly woman
Grow health and also there is important function.
Microecology theory thinks, the composition adjusting therapy righting by ecological agent and protecting intravaginal dominant microflora
The invasion of external " evilness " pathogenic bacteria can be driven away with ratio, improve the self-protection of women's " strengthening vital QI to eliminate pathogenic factors " inherently
Effect.Lactobacillus is the dominant microflora of healthy women vaginal flora, accounts for vaginal bacteria total amount more than 90%, urogenital infections
Patient's Vaginal lactobacilli significantly reduces, and have even can't detect completely, therefore loses and resists external pathogenic bacterial infection
Ability.And pass through the lactobacillus that supplement lacks, then be conducive to rebuilding the dominant microflora of female genitourinary tract, recover it intrinsic
The protective effect of " strengthening vital QI to eliminate pathogenic factors ".
Urogenital infections are the common disease of women, frequently-occurring disease, are easy to recur, though having preferable short-term to treat with antibiotic
Effect, but have 40% recurrence rate.Research has shown that: has the dominant strain lactobacillus curvatus of protective effect or Lactobacillus Jensenii
Preparation will be easier to settle down in vagina and breed, and produce antibacterial material, play lasting effect.Therefore exploitation adapts to China
The specific Lactobacillus vaginalis preparation wide market of women's feature, changes in the past pure on treatment urogenital infections
Pure sterilized medication guide thought, it is to avoid by widely applying a series of bad reactions that antibiotic brought as treatment and disadvantage
End, is conducive to recovering the dominant microflora of female genitourinary tract and rebuilding its microecological balance；Thus effectively reducing urogenital
The recurrence rate of road infection, really cures Female urogenital tract infection.
At present, domestic Female urogenital tract infection only has one kind with probio microbial inoculum, and its main component is De Shi breast bar
Bacterium viable bacteria.Although it is a kind of lactobacillus separated from healthy women vagina, in Bu Shi China woman vagina flora
Main beneficial bacterium.
