Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This application is a U.S. National Phase entry of PCT International Patent Application PCT/RU2005/000231, filed on 28 Apr. 2005. 
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to biotechnology and the creation of new probiotic preparations based on  Bacillus -strain bacteria that can be used as prophylaxis and treatment of infectious diseases and dysbiosis of different origin of human, farm livestock and poultry. 
     2. Discussion of Related Art 
     Biopreparations based on  Bacillus -strain bacteria are well-known. Biopreparations: probiotics based on  Bacillus -strain bacteria contain strains possessing various spectrum of antibacterial and antifungal activity. The effectiveness of these preparations is determined by the width of spectrum and its antibacterial activity contained in strains preparation. 
     The probiotic Bactisubtil (“Marion Merrell” Company/France/) and its analogue Flonivin (“Galenika” Company/Yugoslavia/) are wide spread in medical practice in the West Europe countries. They contain the culture of strain  B. cereus  IP 5832 (collection of Institute Pasteur (Paris)). Well-known Vietnamese preparation Biosubtyl contains the strain  B. subtilis  as an active component. 
     The base of Enterogermina (“Sanofi Winthrop” Company, Italy) is the culture  B. clausii.    
     The biopreparation Cereobiogen (“Xing Lap” Company, China) is also well-known. The effective agent of it is  B. cereus  DM-423 (V. V. Smirnov, S. R. Reznik, I. B. Sorokulova, V. A. Vyunitskaya. Questions for discussion of creation and application of bacterial preparations for micro flora correction of homoiothermal animals: Microbiological Journal, 1992, volume 54, N-&gt;6, p. 82-93). 
     One disadvantage of these probiotic preparations is the restricted spectrum of treatment activity as they are aimed against a small group of pathogenic bacteria. 
     Medical preventive biopreparation Bactisporin for treatment of broad spectrum of diseases, containing lyophilized biomass of the strain Bacillus subtilis 3H and protective media on the base of saccharose-gelatine formula and lactose (Patent RU N° 2130316, A61K 35/66, published on 20.05.1999). 
     However, the biopreparation Bactisporin is not efficient against a set of acute enteropathogenic bacteria, for example, caused by the bacteria of stem  Pseudomonas  spp.,  Streptococcus  spp.,  Enterococcus  spp. 
     Biopharmaceutical preparation Deprecan A, containing recombinant strain of  Bacillus subtilis  is well-known and produces α-2-interferon of the human, strain  Bacillus licheniformis  and an excipient. The preparation can contain recombinant strain of  Bacillus subtilis  BKPM (                               M) No.-7289. The preparation has antibacterial, antiviral and immunomodulatory activity and can be used while treating various diseases of infectious and noninfectious nature (Patent RU No. 2158134, A61K 35/74, published on 20.09.2000).
     However, Deprecan A contains recombinant strain of plasmid, determining resistance to kanamycin, but this does not meet the requirements of World Health Organization. 
     A well-known preparation Biosporin is used prophylaxis and the treatment of gastrointestinal diseases of human, and contains the vital cells of strains  Bacillus subtilis  3 (VKPM (BKΠM, “All-Russian Collection of Industrial Microorganisms”) No. B-2335) and  Bacilllus licheniformis  31 (VKPM, No. B-2336) and a vehicle (Patent SU No. 1722502, A61K 35/74, published on 30.03.1992). 
     Biosporin is characterized by the high antagonistic activity to the wide spectrum of pathogenic and opportunistic microorganisms (Sorokulova I. B., 1997). 
     One disadvantage of Biosporin is that strains contained are susceptible to antibiotics. Therefore this preparation is not recommended to be used together with antibiotics when treating. 
     The closest analogue is the preparation against viral and bacterial infections, containing the mixture of biomass of strain  Bacillus subtilis  BKPM No. B-7092,  Bacillus subtilis  BKPM No. B-7048,  Bacillus licheniformis  BKPM No. B-7038 in its spore form with the titre of not less than 3×10 10  spore/g, and stabilizer, that is, starch and sucrose. (Patent RU No. 2142287, A61K 35/74, published on 10.12.1999). 
     One disadvantage of the well-known preparation is the use of the recombinant strain, containing plasmid, determining resistance to antibiotics. 
     Among the preparations of veterinary application strain Bacillus subtilis X-15 is known and is used for prophylaxis and treatment of cow&#39;s endometritis (Patent RU No. 2180575, C12N 1/20, published on 20.03.2002). 
     One disadvantage of the preparation on the base of stain Bacillus subtilis X-15 is the restricted action spectrum as it is active against a small group of microorganisms, causing the cow&#39;s endometritis. 
     A probiotic preparation Subtilis is also known and is based on liquid or lyophilized freeze-dried strain culture  Bacillus subtilis  VKM No. B-2250 D. This preparation is designed for prevention and treatment of gastrointestinal diseases of animals, birds and fish, and it increases the feed absorbency and increases producing capacity and weight gain (Patent RU No. 2184774, C12N 1/20, published on 10.07.2002). 
     One disadvantage of the preparation Subtilis is its restricted spectrum of antagonistic activity. 
     The closest analogue is the probiotic preparation of compound action, containing the following components, vol. %: mixture of biomass Bacillus subtilis VKPM No. 4759 with the titer 1×10 7 -1×10 9  of live microbial cells and biomass  Bacillus licheniformis  2336/105 with the titer 1×10 8 -10×10 of live microbial cells in 1 ml of normal saline 92 to 98%, and stabilizer based on serum of the cattle&#39;s blood or milk or its mixture, sucrose and gelatin of 2 to 8%. The preparation possesses antibacterial and antiviral activities and is capable for prolonged synthesis of interferon in various parts of open body cavities. (Patent RU No. 2159625, A61K 35/66, published on 27.11.2000)

After storing the pills for 12 months, the content of the live microbial cells in all lots has not been less 10 9-7 -10 8-6  KFU/suppository. 
     Example 5 
     All variants and forms of the biopreparation Irilis according to the Examples 1 or 2 or 3 or 4 are tested for harmlessness on laboratory animals, specific antagionistic activity to test cultures, representatives of various groups of pathogenic and opportunistic microorganisms and resistance to antibiotics. 
     The biopreparation Irilis has harmlessness characteristics. 
     To determine the harmlessness, the content of the bottle is dissolved in 0.5 ml of normal saline and introduce it to the mice orally. For every variant, they use 10 mice, at a weight of 15-16 g. The preparation is considered harmless if all mice stay alive during 5 days of observation and disease was not detected in any mouse. 
     The biopreparation Irilis includes the wised spectrum of antagonistic activity regarding the test-strains of cultures of pathogenic and opportunistic microorganisms. In Table 3, you can see characteristics of antagonistic activity of the preparation regarding pathogenic and opportunistic microorganisms, defined at various infectious diseases and dysbiosis of diverse aetiology. To determine the special activity, the antagonuistic activity of the variants of the preparation are studied regarding the clinical test-cultures. The examination is carried out by method of deferred antagonism. For this, the content of the bottle is dissolved in 1 ml of normal saline. The received suspension is plated along the Petri dish with agar medium Gauze #2. Plating is incubated in the thermostat at 37° C. during 72 hours. Then to the grown culture test-microorganisms are streak plated (5000 mln suspensions of diurnal cultures in the normal saline). The results are checked 18 hours later after incubation at 37° C. by the size of growth absence of test-cultures. 
     Growth control of test-cultures is the parallel growth of them in plates with agar medium Gauze #2 without studied culture. 
     Data from the Table 3 show that the optimal quantity of the alive cells in one dose of the preparation is 1−5×10 9 . The further increase of the microbe cells will not change significantly the antagonistic activity of the preparations regarding the test-cultures of microorganisms. 
     Example 6 
     To determine the therapeutical effect of the probiotic Irilis received according to the Examples 1 or 2 or 3 in comparison with the application of the preparation Pectosorbin, in the farm, piglets with long-term bad gastrointestinal diseases with the symptom complex of diarrhea form 3 groups of piglets of 1-2 days age with clinical sign of dyspepsia (diarrhea, liquefied stool, dejecture had sour smell, contained the gas bubbles, loss of appetite, dryness and paleness of the mucous tunics, rapid pulse, muffled heart sounds, tachypnoe). 
     After clinical examination it was determined that 69 piglets have trivial dyspepsia, and 12 piglets have toxical dyspepsia. 
     While conducting the bacteriological study of the samples of piglets&#39; faeces in all ill piglets the pathogenic  Escherichia  (10 8 -10 11  bacteria in 1 g) are detected in large quantities, whereas the  Escherichia  strains of the normal representatives of the large intestine can be detected only at 8 piglets (10 3 -10 4  bacteria in 1 g). 
     Pathogenic  Escherichia  in contrast to the normal representatives of the intestine, as a rule, does not ferment the lactose and cause the death of the mice while intraperitoneal introduction. While serotyping the detected strains of the pigs, 11 strains belong to the enteropathogenic serogroup 0141; the remaining 40 strains did not agglutinate by the type specific serum. The results of the study show the disorder of the micro flora of the large intestine of the ill piglets with dyspepsia (dysbacteriosis) that is the cause of their disease. 
     The piglets of the first and the second group after 3-4 hours of water-starvation diet 20-30 minutes before the feeding are given Irilis in the amount of 2 and 4 doses respectively 2 times a day with the interval of 12 hours before the clinical recovery. The piglets of the third group three times a day before clinical recovery take Pectosorbin with colostrums in the dose of 0.26 g for every kilo of live weight according to the instruction for use. The piglets are observed clinically taking into account the number of recovered piglets and the duration of treatment. The recovery is detected by the absence of diarrhea signs, pathological additives in faeces, meteorism (tympanism), spasms, improvement of general condition, appetite. The results are shown in Table 4. 
     As shown in Table 4, probiotic Irilis provides high effectiveness while applying it in the amount of 4 doses 2 times a day. The recovery comes after 4 to 6 times of applying Irilis while following the diet. Normalization of gut organisms eliminates the dehydratation and this excludes the necessity of rehydration measures. After cancellation of the preparation the disease is not detected. 
     Example 7 
     To determine the efficiency of the preparation Irilis when treating the calves with symptom complex of diarrhea and the evaluation of its prophylactic action on the animals up to 2 months age, three groups of 100 healthy newborn calves of 1 to 2 days old, were formed. The weight of calves at birth is 28 to 30 kilos. 
     The calves of all groups were fed according to the recommendations of growing procedure: 1.5 to 2 liters of colostrums (milk) during every feeding three times a day. For the first time the colostrums is given not later than after 1.5 hours after birth. The calves of the first two groups (40 animals each) are given the preparation 20 to 30 minutes before the second feeding during five days by two courses with the interval of 3 to 4 days: the preparation Irilis is given of 1 and 2 doses correspondingly. Before giving the preparation, the content of one ampoule (bottle) is dissolved in 0.100 ml of water boiled and then cooled to the temperature of 38-39° C. The calves of the first group are given 50 ml, the calves of the second test group are given 100 ml of the preparation. The third group is a control group (20 animals) and it is not given the preparation Irilis. 
     The calves are weighted at birth and at the age of 2 months. Every day their physical condition, appetite and the functioning of their digestive system (type of feces, meteorism), and behavior of an animal are observed. At the end of experience, five calves of every group are taken blood tests for hematomancy. With a Sahli hemoglobinometer the hemoglobin in their blood is detected, with a Gorjaev&#39;s chamber the blood cells are detected, with a general method their leukogram is determined, and the concentration of the whole protein in blood serum is defined refractometrically. The content of immunoglobulins is detected by a zinc sulphate test, and the content of lisolim is defined according to E. V. Ermolaeva, germicidal activity determined according to S. V. Smirnova and T. A. Kuzmina. The results of the study are shown in the Table 5. 
     As shown in the Table 5, application of the probiotic Irilis does not influence significantly the concentration of hemoglobin in the blood, the number of blood corpuscles and leukogram. Moreover, in the blood of the calves that were given the preparation the level of whole protein in the blood serum, immunoglobulins, lizopim and serum bactericidal activity increase considerably. 
     It was determined that Irilis does not influence negatively the health of animals, but it increases greatly their gastrointestinal diseases resistance, improves the quality of their lives, and they do not lose weight. (Table 6) 
     As shown in the Table 6, in the control group that was not given the preparation 15 calves of 20 got ill, that is 75% of the number of animals in the group, but in the first test group (1 dose of Irilis 1 time a day), 11 calves of 40 (27.5%) got ill and in the second test group (2 doses of Irilis 2 times a days) 7 calves of 40 (17.5%) got ill. Prophylactic efficiency of the probiotic Irilis is 72.5% and 82.5% correspondingly. 
     The calves of the control group get ill at the 2 nd  and 9 th  day, and the disease is of serious form. As a result the death animals are 30% and the alive animals are 70%. The application of the preparation Irilis in the amount not less than 2 doses is not worthwhile. That is confirmed by the high percents of the alive animals and average daily weight increment of 95% and 9% correspondingly. 
     Example 8 
     Application efficiency of the preparation Irilis for prophylactic of gastrointestinal diseases with symptom complex of diarreas is determined on the farm, having long-term unfavorable results of these diseases, in comparison with the preparations pectosorbin and immunoglobulin. 105 new born calves are divided into three groups of 35 animals each. All animals are healthy, normally developed and the difference among the groups of the average live weight does not exceed 2%. 
     The calves of the first group are given the preparation Irilis (2 doses) 20 to 30 minutes before the colostrums. The calves of the second group are given pectosorbin according to the recommendations of its application. The calves of the third group are given unspecific immunoglobulin intramuscularly according to the recommendations of its application. 
     Prophylactic course of groups is: for the first group—10 days, for the second group—10 days, for the third group—50 days. Observation period is 60 days. Calves are weighed at birth, one month later and at the end of the observation period. Every day a clinical condition is observed, taking attention to the number of ill animals, clinical course and clinical outcome. The results of study are shown in the Table 7. 
     As shown in the Table 7, the efficiency of the probiotic Irilis in comparison with well-known preparations pectosorbin and immunoglobulin is much higher, that is confirmed by the rates of alive animals and average daily growth of body weight. 
     Example 9 
     The tests of introducing the probiotic preparation Irilis into the traditional scheme of feeding in the poultry farming while breeding the broiler chickens are carried out. The chickens are divided into 4 groups, that are given are: 
     1 g. Of the preparation πpeπapaτ &lt;&lt;Vetom&gt;&gt; manufactured by NPF-IZ &lt;&lt;Koltsovo&gt;&gt;, 
     2 g. Of the preparation Irilis 
     3 g. Of the preparation STF, manufactured by &lt;&lt;Bioavtomatika&gt;&gt; Company Limited, 
     4 g. Of the preparation &lt;&lt;Enterosporin&gt;&gt; 
     Experimental prophylactic scheme of day breeding is the following: 
     1 st  day—probiotics with feeding 
     1-3 days—fluoroquinolones 
     4-13 days—probiotics with feeding. 
     Further, the prophylactic scheme used on the farms is applied. 
     Results are registered according to the main technological factors: weight of chickens at 1st, 7th, 14th, 28th, 35th and 42nd days and when taking to slaughtering; calculations of loss of cattle every week and total when taking to slaughtering. The results of study are shown in the Table 8. 
     Data provided in the Table 8 show that the usage of the preparation Irilis during the process of breeding the chickens provides the high results of livestock survivability. The preparation Irilis influences positively the organism of chickens, providing the big increase of live weight in comparison with the control. 
     Consequently, the tests carried out of the preparation Irilis have revealed the possibility and high efficiency of its application while growing the livestock and poultry. It provides the inhibition of the pathogenic  Escherihia , maintenance of the optimal microbial balance in digestive tract, increase of non-specific animal resistance, their safety and growth of body weight, has prophylactic medical effect against the diseases that are followed by the diarrhea and it also a prophylactic remedy from the dysbacteriosis. The advantage of the preparation Irilis is the chromosomal resistance to antibiotics contained in its strains. This makes it possible to apply this preparation in the complex of antimicrobial therapy.
