[0026] Preparation of lactic acid bacteria

[0027] First, the specific preparation method of the composition containing lactic acid bacteria used in the present invention is demonstrated here. The lactic acid bacteria of the present invention can be cultured in a culture medium, which can be any culture medium that provides good growth of the microorganism without contamination, loss of genetic stability, or loss of characteristics of other lactic acid bacteria strains. More specifically, the lactic acid bacteria strain of the present invention is grown in a culture solution containing assimilable carbon sources, assimilable nitrogen sources, appropriate salts and trace metals. The preferred culture medium for cultivating lactic acid bacteria strains of the present invention is MRS culture medium.

[0028] The lactic acid bacteria microorganism of the present invention can be cultivated under traditional culture conditions, which include but not limited to agar surface cultu...

example 1

[0039] The composition containing lactic acid bacteria is coated on the condom, wherein the condom is formed, inspected, removed and screwed up, and then heat-sealed (heat-sealing) and then these compositions will slowly penetrate and distribute On the entire surface of the condom, a coated condom with wetting and proper lubricating properties is obtained.

example 2

[0041] An aqueous solution of lambda-carrageenan and isopropanol was placed in the solution tank into which the condom (still covered in the condom maker) was soaked after the pinhole test.

[0042] Afterwards, the condom is taken out from the solution tank, followed by the steps of drying, checking, unloading and top-spinning. By this method, a condom uniformly coated with a composition containing lactic acid bacteria can be obtained.

Abstract

The present invention relates to a condom coated with lactobacillus compositions for enhancing the effect of contraception and preventing venereal infection, and for constructing, maintaining and reconstructing non-pathogenic, natural or genic recombined colonies in vagina. The lactobacillus may be natural or genic recombined lactobacillus in intestinal tract or vagina of mammal. The compositions coated on the condom comprise lactobacillus in the form of powder or other forms, such as emulsion, foam, microbeadlets or micro-encapsulated form, and comprise at least one kind of living lactobacillus strain, and selectively comprise one kind of lubricant. Vaginal pathogenic microbial infection and viral infection can be reduced or prevented, and better conditions can be maintained without side effect by using the condom of the present invention.

Description

technical field [0001] The invention relates to a condom coated with a composition containing genetically modified or natural lactic acid bacteria, and the effect of the condom of the invention on human health and prevention and treatment of venereal diseases. Background technique [0002] In the prior art, bactericidal and spermicidal compositions have been widely used in creams, foams and suppositories, either by themselves or in combination with various mechanical contraceptive devices, mainly for contraceptive purposes. Nonoxynol 9 is a spermicide, which has been reported in the prior art to have a certain bactericidal effect and can kill human immunodeficiency virus (HIV). However, the use of spermicides or antiseptics such as Nonoxynol 9 in condoms or other vaginal suppositories is problematic because it tends to destroy or reduce the healthy vaginal flora and poses a risk for women to be infected with other microorganisms, such as fungal infections. [0003] Condoms ...
