The invention relates to biotechnology and for the creation of new probiotic preparations on the basis of bacteria of the genus Bacillus, which can be used for the prevention and treatment of infectious diseases of humans and dysbiosis of various etiologies.
It is known that a major problem in the treatment of tuberculosis is multiresistance of bacteria to antibiotics, that creates an insurmountable obstacle to reducing the incidence of TB extensively drug-resistant (so-called XDR-TB or XDR-TB). When XDR-TB, in addition to drug resistance, characteristic of multiresistentsuse adds resistance to all fluoroquinolones and at least one of three injectable second-line drugs (capreomycin, kanamycin or amikacin) (who Report no WHO/HTM/TB/2010.3). Currently, there are strains of Mycobacterium tuberculosis resistant to three or four or five or even six antibiotics, including antibiotics reserve, and therefore the question of search of drugs, allowing to solve the problem.
Described treatment-and-prophylactic probiotic agent (EN 2314819 C1, Lalic and others, 20.01.2008)biomass bacteria spores of the genus Bacillus. Contains the bacterial strain Bacillus subtilis VKPM B-7048, and/or the bacterial strain Bacillus subtilis VKPM B-7092, and/or bacterial strain Bacillus licheniformis VKPM B-7038. Ensure the leads to a significant expansion of the range and increase the biological activity of therapeutic-prophylactic probiotic means however, the possibility of recovery of sensitivity to antibiotics under the action of the tool.

Strains of B.subtilis VKPM B-8611 and B.licheniformis VKPM B-8610 characterized by high antagonistic activity against wide spectrum of pathogenic and conditionally pathogenic microorganisms and resistance to several antibiotics (Table 2, 3). These properties allow you to apply Balys simultaneously with antibiotics, with the strengthening of the common antibacterial effect.
As part of the proposed biological Balys these strains can be used in various combinations, for example in equal proportions (titer cells): biomass of strain .subtilis VKPM B-8611 in titer of 1·109CFU/ml and biomass of strain B.licheniformis in titer of 1·109CFU/ml or in any ratio in the range of (1-100):(100-1), for example, the biomass of the strain .subtilis VKPM B-8611 in the titer of 5 x 109CFU/ml and biomass of strain B.licheniformis VKPM B-8610 in titer of 1·109CFU/ml, or biomass of strain .subtilis in titer of 1·1010CFU/ml and biomass of strain B.licheniformis PMBC No-8610 in title 5·109CFU/ml, or biomass of strain .subtilis VKPM B-8611 in titer of 1·109CFU/ml and biomass of strain B.licheniformis VKPM B-8610 in titer of 1·107CFU/ml, etc.
To obtain sterile filtrate the living cultures of the strains subtilis VKPM B-8611 and B.licheniformis VKPM B-8610 cultivated separately at constant shuttlebay at 37°C. Biomass is filtered through sterilizing filters with a preliminary centrifugation (g=9859,6 m/s2). The pH was adjusted to 6.0±0,05.
The target product is extracellular products of vital activity of strains of B. subtilis VKPM B-8611 and B.licheniformis VKPM B-8610. The filtrates live cultures subjected to freeze-drying and the resulting substance stored at a temperature not above 20°C. the Substance is stable, does not change in the process of freeze-drying and during storage for 2 years.
In the manufacture of the drug used dried substance, but it is possible and the use of the effluent in liquid form. As part of the proposed drug Balys this substance can be used in an amount of 3 mg/ml
To obtain legislatively substance as a producer used Lactobacillus fermentum strain 90-NS-4(21) (strain deposited in Russian national collection of industrial microorganisms under registration number In-7573). After sieving strain L. fermentum 90-TS-4(21) were sampled colonies on the basis of agglutination with Kona on the glass at a concentration of at least 1.75·10-3mg/ml
Selected variant strain L. fermentum 90-TS-4 (21) were cultured on liquid medium MPC-1 in a 1000 ml in CO2-conditions for 15-17 hours at a temperature of 37(±0,05)°C and constant stirring.

Supernatant culture fluid was transferred to the cell company AMICON (USA) (2000 ml) and was freed from low molecular weight components and the residual amount of bacterial cells using sterilizing membranes brand "Mile-long" with a pore diameter of 0.02 mm.
Purified culture fluid was concentrated at the cell company AMICON (USA) (2000 ml) using membranes "Diablo" stamps UM-20 to volume of 100 ml at the same time the supernatant culture fluid washed three times with distilled water from lactic acid, bringing the pH to a value of 6.0±0,05.
The resulting concentrate of the culture fluid of strain L. fermentum 90 TS-4 (21) were incubated for 24 hours at room temperature with Kona-separate. After days adosados was removed, and con-sepharose washed three times with phosphate buffer (pH of 8.2). Next was added saline solution (pH 3.0) and incubated for 3 hours at room temperature. Collected adosados and brought it up to a pH of 7.2 with 0.1m NaOH. The presence legislatively substance controlled using a 0.1% solution of Koh in the reaction of calcarenitic.
The target product is anti-adhesive component on the basis of legislatively structures strain L. fermentum 90 TS-4(21) has the following characteristics:
the component containing the 150,0 mg/ml protein, aggregative newsto is constant at pH values above 6.0;
the molecular mass determined using polyacrylamide gel electrophoresis, is from 25 to 30 kDa;
properties legislatively substance is stable and does not change during storage and during lyophilization.
Legislatively substance has a modulating effect on the adhesive activity of the test cultures of yeast fungi of the species C. albicans and conditionally-pathogenic strains of the species E. coli (see EN 2367686).
Modulating the property fraction, devoid of the ability to respond with Kona, and faction, capable of reacting with Kona concentrate cultural liquid (QL) L.fermentum strain 90 TS-4 (21) in the test of inhibition of adhesion of test-cultures of epithelial cells of the vagina (EV), showed the following (see Table 4). Chromatographically purified fraction legislatively active substance inhibits the adhesion of vaginal isolate of yeast fungi of the species C. albicans strain 04.703 B in epithelial cells and to a lesser extent affects the adhesion of oral isolates of yeast fungi of the species C. albicans. Adhesion of E. coli strain K 12 fraction has no effect, but substantially blocks the adhesion of E.coli strain 89-1449 epithelial cells of the vagina. At the same time when removing legislative component is enhanced adhesive activity part of the test cultures of E. coli to epithelial cells of the vagina. Adhesion vaginal isolate of drozhzhepodobny the fungi species .albicans strain 04.703 in this model system was significantly decreased. These data confirm that you have received legislative component with a strong modulatory activity against high adhesive strains of yeast-like fungi species .albicans and other opportunistic pathogens.
When composing multicomponent probiotic preparation Balys ratio of live strains of VKPM B-8611 and .licheniformis VKPM B-8610 can be changed at specific intervals, as described above. The filtrates of live cultures of strains VKPM B-8611 and .licheniformis VKPM B-8610 (extracellular substance) were added in amounts of about 3 mg Legislatively substance Lactobacillus fermentum 90 TS-4 (21) was added in an amount of about 6 mg biologic Balys also contains a protective environment for preservation of bacteria during processing, the final prescription form and subsequent storage. As a protective environment it may contain, for example, Saharsa gelatin Wednesday, milk powder, gelatos, lactose, sucrose, etc. biological Balys may further comprise a solvent. The solvent may be used, for example, distilled or boiled water, saline, etc.

This statement is illustrated by the following results (see Table 4).
Spore probiotics have a set of properties that allows you to compete with pathogenic and conditionally pathogenic microorganisms. These properties include: antagonistic activity, the capacity for adhesion to epithelial cells, a certain level of resistance to hydrochloric acid, bile, etc. But still not studied the action of these drugs on the causative agents of tuberculosis infection. In recent years, along with increased morbidity and mortality from tuberculosis has increased the number of multi-drug resistant TB (MDR-TB) and strains with extensively drug-resistant (XDR-TB) Mycobacterium tuberculosis. The clinical picture of drug-resistant tuberculosis manifests itself in the patient when the population is Oia multidrug-resistant Mycobacterium far exceeds the population of bacilli, sensitive to drugs. When studying the antagonistic activity of the drug Balys used reference strains Academia (M.tuberculosis), Vallee (M. bovis), Ravenal (M. bovis), GIS (M.avium)obtained from gisk named after. Laurasia. As indicator strains were also used isolated from cattle and we identified cultural, biochemical and chemotaxonomic methods strains .bovis (No. 3, Ryazan) - see Table 5, 6. In addition, 20 patients with tuberculosis were isolated and identified 20 drug-resistant strains of M. tuberculosis (Table 7). Method to study the antagonistic activity of probiotic strains against Mycobacterium tuberculosis involved the use of culture filtrates of liquids, obtained through sterilizing filters (see Lazovsky A.L., and others, the Effect of probiotics on pathogenic mycobacteria // Problems of tuberculosis and lung diseases. Publishing house "Medicine", M., 2006. No. 7. - 25-27). Analysis was performed within 25-30 days incubation at 37°C index block growth (IBR) of mycobacteria. IBR was determined by calculating the ratio of the number of colonies grown on the control medium without probiotic, to the number of colonies grown on the medium with a probiotic. The maximum IBR considered the number 10.
Effect spore probiotics on medicinal Chu is stateliest mycobacteria studied on 20 clinical strains isolated from TB patients people. Used the above processing methods spore probiotics. The drug sensitivity was determined in accordance with Order No. 109 from 21.09.03. "On improving TB control in the Russian Federation". The results are presented in the figure. In this experiment, we used the following drugs in different concentrations: 1, 2 - streptomycin, 10 and 25 µg/ml, respectively; 3, 4 - isoniazid 1 and 10 μg/ml; 5 - kanamycin 30 µg/ml; 6 - ethambutol 2 µg/ml; 7 - rifampicin 40 μg/ml; 8 - ethionamide 30 µg/ml; 9 - ofloxacin 2 µg/ml; 10 - capreomycin, 30 μg/ml; 11 - PASK (paraaminosalicilovaya acid) 1 mg/ml
All reference strains studied probiotics showed antagonistic activity. As shown in Table 5-7, spore probiotics inhibited the growth. M.tuberculosis. Index block growth (IBR) in 20 strains of Mycobacterium tuberculosis ranged from 1 to 10.
The study of drug susceptibility of isolates grown on media with a sterile filtrate showed that restoration of drug sensitivity was 80%, and 95% of the original cultures were resistant to 1, 2, 3, 4, 5, 6 or even 7 anti-TB drugs. 20% of strains were resistant to 7-8 antibiotics, i.e. treat XDR-TB and MDR-TB. 20 drug-resistant clinical strain is in mycobacteria in 16 (80%) recovered sensitivity to one, two, three, four or five drugs.
