Reference method laboratory studies of the activity of antimicrobial agents against rapidly growing aerobic bacteria causing infectious diseases. and according to the Guidelines MUK 4.2.1890-04 Susceptibility Testing of Microorganisms to Antibacterial Agents (approved and effective Mar. 4, 2004).

[0046] During the study, the antimicrobial activity of the inventive biologically active supplement comprising a combination of Usnea barbata lichen, common barberry berry, and three-lobe beggarticks herb extracts was evaluated for antibiotic-sensitive and antibiotic-resistant microorganism strains of clinical significance. During the study, the minimum inhibitory (MIC) and minimum bactericidal (MBC) concentration as well as minimum inhibitory (MI.sub.FC) and minimum fungicidal (MFC) concentrations were determined for the extracts of Usnea barbata lichen, common barberry berries and three-lobe beggarticks herb for Candida albicans.

[0047] The antibacterial and antifungal activity study of the inventive composition and the identification of MIC, MBC, MI.sub.FC, and MFC were performed at the Department of Microbiology in Smolensk State Medical University at the Ministry of Healthcare of the Russian Federation. For the study, the following strains from the specialized collection and clinical isolates from the collection of the Scientific Research Institute of Antimicrobial Chemotherapy at the Smolensk State Medical Academy (hereinafter as SRIAC SSMA) were used: Salmonella enteritidis, strain 14028, Klebsiella pneumoniae, expanded-spectrum -lactamase (ESBL) producing strain ATCC 700603, Acinetobacter baumannii, strain ATCC 19606, Streptococcus pneumoniae, strain ATCC 49619, Streptococcus pyogenes, strain ATCC19615, Streptococcus agalactiae, strain ATCC 12386, Enterococcus faecalis, strain ATCC 29212, Escherichia coli, strain ATCC 25922, Escherichia coli, ESBL producing strain ATCC 35218, Pseudomonas aeruginosa, strain ATCC 27853, Pseudomonas aeruginosa, metallo-beta-lactamase producing strain (MBL-producing Pseudomonas aeruginosa), Staphylococcus aureus, strain ATCC 25923, Staphylococcus aureus methicillin-resistant (MRSA), Haemophylus influenza, strain ATCC 49766, Enterobacter cloacaeESBL producing clinical isolate, and Candida albicans, strain ATCC 10231.

[0048] Microbial enumeration test of a test sample was performed following the methods in Russia State Pharmacopoeia (XIII edition, volume 1, GPA.1.2.4.0002.15 Microbiological purity). Susceptibility testing of microorganisms to the test composition of the inventive biologically active supplement was performed following the broth serial dilution microtechnique in sterile polystyrene flat-bottomed 96-well plates (Sarstedt, Germany).

[0049] For the present study, stock solutions of the extractions from the composition of the invention were used followed by double dilution thereof:

[0050] 0.2%-0.1%-0.05%-0.025%-0.0125%

[0051] 2%-1%-0.5%-0.25%-0.125%

[0052] 20%-10%-5%-2.5%-1.25%

[0053] The pre-extractions from the composition of the invention were filter sterilized. To control sterility, the filtered solutions were added to thioglycolate medium in a ratio of 1:10, followed by incubation at 35 C. for 48 hours, and followed by seeding on FMH agar to validate the absence of microbial growth.

[0054] Inoculum with the final composition of microbial cells: 510.sup.5 CFU/ml.

[0055] Nutrient media: Mller-Hinton broth, Mller-Hinton agar (M-H broth will be used for the microplating method in broth, M-H agar will be used for cultivation of the daily indicative bacterial culture and MBC detection (MFC for Candida albicans) in the extracts of Usnea barbata, three-lobe beggarticks, and common barberry.

[0056] Controls: the nutrient broth without microbial culture (negative control); the nutrient broth with microbial culture without plant preparation (positive control).

[0057] The determination of minimal inhibitory (MIC; MI.sub.FC for Candida albicans) and minimal bactericidal concentrations (MBC; minimum fungicidal concentration, MFC, for Candida albicans) in extractions from the composition of the invention was performed by microdilution method in the broth in sterile polystyrene flat-bottomed 96-well plates (Sarstedt, Germany) Two-fold serial dilutions in the Mller-Hinton broth (BD, USA) were prepared from the stock solutions of plant extracts of Usnea barbata, three-lobe beggarticks herb and common barberry berries (0.2%, 2%, 20%) from 20% solution to 0.0125%. Bacterial suspensions having an optical density of 0.5 McFarland (110.sup.8 CFU/ml) were prepared from daily cultures of test microorganisms grown on M-H agar in the sterile isotonic solution. The adjusted inoculum was diluted in the broth to provide the final cell concentration of 510.sup.5 CFU/ml (between 210.sup.5 CFU/ml and 810.sup.5 CFU/ml). Transferring 0.1 ml of the standardized organism suspension to a tube containing 9.9 ml (at the dilution ratio of 1:100) of the broth yields a suspension having the cell concentration of 110.sup.6 CFU/ml while adding 5 l of which to 100 l of the antibacterial agent solution produced the final inoculum composition of 510.sup.5 CFU/ml. The plates were incubated in an incubator for 18 hours at 35 C. MIC was registered based on the absence of microorganism visible growth by comparing the experimental and control wells. For MBC determination, 10 l of each well was plated onto a sector of a solid nutrient medium (M-H agar). Following the incubation for 24 hours at 35 C., the microorganism growth on the nutrient medium was evaluated.

[0058] The minimum concentration preventing microbial growth is indicated as the minimum inhibitory concentration (MIC; MI.sub.FC for Candida albicans); the minimum concentration killing 99.9% of microorganisms (from the baseline) is indicated as the minimum bactericidal concentration (MBC; MFC for Candida albicans).

[0059] Dilution concentrations in extracts of Usnea barbata lichen, common barberry berries, and three-lobe beggarticks herb, and all subsequent concentrations and ratios thereof were adjusted, when necessary, during the study as new data become available.

[0060] The data provided in Tables 1 to 3 show that for Candida albicans (strain ATCC 10231) MI.sub.FC for monoextracts of Usnea barbata lichen, three-lobe beggarticks herb, and common barberry berries was 0.25, 0.01 and 0.1 mg/ml, respectively. The fungicidal effect against Candida albicans (strain ATCC 10231) was not found in monoextracts of Usnea barbata, three-lobe beggarticks herb, and common barberry berries.

[0061] In contrast, the inventive biologically active supplement comprising a combination of extracts of Usnea barbata, three-lobe beggarticks herb and common barberry berries, from the data obtained within the present study presented in Table 4, surprisingly exhibited fungicidal activity against Candida albicans, with minimal fungicidal concentration (MFC) of 0.1 mg/ml, although such fungicidal activity could not be predicted from the prior art.

[0062] In addition, from the data obtained within the present study and presented in Table 4, the inventive biologically active supplement exhibits the over-cumulative antibacterial, including bactericidal, action against the wide range of Gram-positive and Gram-negative microorganisms, such as against Salmonella Salmonella enteritidis, Klebsiellas including ESBL producing strains of Klebsiella pneumoniae, Acinetobacteria including without limitation Acinetobacter baumannii, Streptococcus including without limitation Streptococcus pneumoniae, Streptococcus pyogenes and Streptococcus agalactiae, Enterococcus including without limitation Enterococcus faecalis, Escherichia including without limitation Escherichia coli, particularly ESBL producing strains of Escherichia coli, blue pus bacillus (Pseudomonas aeruginosa) including without limitation MBL producing strains of Pseudomonas aeruginosa, Staphylococcus including without limitation Staphylococcus aureus, such as methicillin-resistant Staphylococcus aureus (MRSA), as well as against Haemophilus influenzae and Enterobacter including without limitation Enterobacter cloacae, in particular (without limitation) against Enterobacter cloacae strains producing expanded spectrum -lactamases.

[0063] The data obtained during the study support the inventor assumption made within the scope of the present invention that the claimed biologically active supplement comprising extracts of Usnea barbata lichen, three-lobe beggarticks herb and common barberry berries and, optionally, extracts of black elder berries and Baikal skullcap roots, and fermented black garlic powder has the over-cumulative (synergistic) antibacterial, including bactericidal, action against the wide range of Gram-positive and Gram-negative microorganisms including antibiotic-resistant strains of Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Enterobacter cloacae and Staphylococcus aureus and fungicidal action against Candida albicans, thereby the claimed biologically active supplement can be used not only for prevention and adjuvant therapy of the wide range of bacterial infections but also for prevention and adjuvant therapy of candida infections. These properties of the claimed biologically active supplement couldn't be predicted from the prior art.

[0064] Hypothetically, the technical results supported within the scope of the claimed invention by the above examples could be accounted by mutual potentiation of the active substances in the extracts of common barberry berries, three-lobe beggarticks herb and Usnea barbata, and optionally the Baikal skullcap root extract, elderberry berry extract, and fermented black garlic powder, which, when used as monoextracts, do not have a significant fungicidal effect. Provided technical results are unexpected, therefore the claimed invention is not obvious in view of the prior art.
