A bacillus is a rod-shaped bacterium. Bacillus bacteria What is a bacillus

Bacteria bacilli exhibit pronounced antagonistic activity. Therefore, bacilli are often used against bacteria that disrupt microflora, to treat dysbiosis or infections in both medicine and veterinary medicine.Unfortunately, the bacilli cannot take root in the human body and die a few days after stopping the drug.

Medicines containing antibacterial bacilli can be taken orally. This method of administration is used not only for diseases of the gastrointestinal tract. With the help of translocation, which I have already written about before, bacilli are able to penetrate through the intestinal wall into the blood, and from there into the wound.

Therefore, in order to prevent postoperative complications, drugs with bacilli are taken orally. In some cases, it is easier not to rely on it and use the drugs topically, for example, for vaginal irrigation.

The use of drugs containing bacilli

Sporobacterin dried bacilli

Contains live freeze-dried bacilli "Bacillus subtilis", which produce a broad-spectrum antibacterial substance. It suppresses the development of many pathogenic bacteria. Moreover, normal microflora is resistant to the action of this substance. The bacilli also produce many enzymes that break down proteins, fats, carbohydrates, and fiber, which helps cleanse wounds and inflammatory foci of dead tissue, as well as improve the digestion and absorption of food.

Dried spobacterin bacilli are a drug with a wide range of applications. It can be used to treat acute intestinal infections and dysbiotic conditions of the large intestine. During treatment, it is necessary to monitor the state of the intestinal microflora using bacteriological studies. It is impossible to combine the use of sporobacterin with the use of antibiotics and antibacterial chemotherapy drugs.

For the treatment of wound infections and osteomyelitis spobacterin bacilli also taken by mouth. It itself penetrates wounds from the intestines through the blood. At the same time, it is recommended to use hypertonic solutions of sodium chloride (10%), glucose (40%), and urea (10-30%) for washing wounds and dressings.

Contraindications for use bacilli spobacterina are absent, but it should be used with caution in case of microbial allergies. In rare cases, after taking Sporobacterin, it is possible side effects: chills, fever, nausea, vomiting, loss of appetite, rash. They disappear within 24 hours after reducing the dosage or stopping treatment.

Bactisporin complex drug

It differs from sporobacterin only in the variety of bacilli.
Biosporin contains two types of live bacilli (B. subtilis and B. licheniformis), characterized by the ability to suppress the development of pathogenic and opportunistic microorganisms without affecting the normal microflora.

The presence of two types of bacilli in the preparation is of fundamental importance, since they successfully complement each other in terms of the spectrum of antimicrobial activity. The drug inhibits the development of staphylococci and many types of bacteria that cause acute intestinal diseases.

Biosporin immune stimulant

Not only suppresses the development of harmful microorganisms, but also stimulates the immune system. The drug is used to treat acute intestinal infections and correct intestinal dysbiosis in children over one year of age and adults.

Regarding dosages, you should definitely consult your doctor. During treatment with Biosporin, the use of antibiotics and chemotherapy is not advisable. There are no contraindications to the use of biosporin. The drug does not cause adverse reactions.

Bactisubtil protector of intestinal microflora

Designed specifically for the treatment of intestinal dysbiosis. He contains special variety bacilli 1P 5832 (ATCC 14839), which were obtained by employees of the Pasteur Institute and have pronounced antagonistic activity against Escherichia coli, Proteus, and staphylococci.

Each capsule of the drug contains 1 billion bacilli, as well as excipients: calcium carbonate, white clay, gelatin, titanium oxide. The capsule protects spores from the harmful effects of gastric juice.

Baktisubtil helps restore the biological balance of the intestinal environment during diarrhea (diarrhea) and dysbiosis, suppressing the development of pathogenic bacteria and simultaneously stimulating natural lacto- and bifid flora. Bactisubtil bacilli help improve the breakdown and absorption of food, restore the balance of vitamins, maintain optimal acidity of the contents, reduce gas formation, and have a proven immunocorrective effect.

The drug is used primarily in the treatment of diarrhea and intestinal dysbiosis, as well as for prophylactic purposes. Bactisubtil can be prescribed to children of any age and adults. If there is difficulty swallowing the capsules, they are opened and the contents are mixed with water or food, depending on the age. Bactisubtil bacilli do not persist in the body and completely disappear from the intestines 48 hours after administration.

Flonivin-BS

The drug, containing in one capsule at least 1 billion bacilli of strain IP 5832, which have high antagonistic activity, was obtained artificially. They do not take root in the human intestine and disappear within 48 hours after stopping oral administration. Distinctive feature The drug is resistant to most of the most widely used modern antibacterial drugs.

This makes it possible to combine treatment with flonivinom bacilli with other antimicrobial drugs. Used for diarrhea in infants and intestinal diseases in adults to normalize the composition of the intestinal microflora, for example, after taking broad-spectrum antibiotics.

Flonivin is prescribed to adults and children from 3 to 12 years old, 4-6 capsules per day between meals. Children under 3 years old - 3-4 drops per day, the contents of the capsule should be added to sweetened water, juice or milk.

Dairy starters

And also to create a protective microflora, live bifidobacteria bacilli are required, which are present in, from which very tasty and medicinal yoghurts, kefir and fermented baked milk can be prepared at home. They are used to create protective intestinal microflora for both adults and children.

In unfavorable living conditions, bacilli form spores that can remain viable for hundreds of years. When exposed to favorable conditions, the spores germinate and the bacteria begin to multiply again.[...]

Some bacteria (bacilli) in unfavorable living conditions are characterized by sporulation - the appearance of a round or elliptical body inside the cell. Almost the entire content of the protoplasm is spent on the formation of a spore. Spores are able to withstand temperatures up to 100° C for several hours; they do not die when dried, frozen, exposed to direct sunlight and even strong chemical poisons; Spores die only when sterilized in autoclaves. When exposed to favorable conditions, the spores develop into normal cells; some bacilli restore the cell within 40-50 minutes[...]

Under the conditions of series 2, the activated sludge was colonized by bacilli; The duration of the oxidation process is 180 days. The biomass concentration at the beginning of the experiment was 0.02 g/l, at the end of the experiment 0.3 g/l; economic coefficient 30%. The amount of contaminants oxidized by extracellular enzymes was 0.25% of the dry matter of activated sludge.[...]

Currently, cultures of these types of spore-bearing bacteria are widely used in many countries for the industrial production of amylase and various proteases.[...]

Bacteria of the hay and potato bacillus group are causative agents of diseases of baked bread and pasta.[...]

Some rod-shaped bacteria (bacillus, clostridia) produce spores that are highly resistant to environmental factors. Sporulation inside a bacterial cell is accompanied by the appearance of an area with cytoplasm of a more viscous consistency, which is surrounded by a dense, waterproof membrane. Water in spores is in a bound state. This explains the resistance of spores to high temperatures. They are less susceptible to the action of substances toxic to bacteria. With the onset of favorable conditions, the spore germinates, giving rise to a bacterial cell.[...]

If the spore is in the middle of the cell, the bacillus swells, taking on the shape of a spindle - a clostridial shape. In cases where the spore is located at one end of the cell, the resulting drumstick shape is called plectridial (Fig.[...]

According to modern concepts, aerobic spore-forming bacteria, or bacilli, are combined into a separate genus Bacillus of the Bacillaceae family. This genus, which contains many diverse species, has a number of characteristic features and differs from other bacterial organisms by a complex of morphological and physiological characteristics, the most important of which are the rod-shaped shape of cells, the ability to form endospores, and the need for free oxygen for growth. [...]

Pollution of the environment with bacilli (spores) poses a particular danger to animals (and people). anthrax. Spores of the causative agent of anthrax are resistant to exposure to factors natural environment. They persist in the soil for decades and pose a potential threat of infection to animals and people. During flood and storm water spills that erode soils, reclamation work, and road construction, spores of the anthrax pathogen from deep layers of soil can be carried to the surface of the earth. The bio-geochemical food chain soil -> plants -> animals -> humans is polluted, and the risk of outbreaks of epizootics and anthrax epidemics increases sharply. The protection of pasture biogeocenoses and their environment from bacterial contamination is an acute environmental, veterinary, medical, sanitary and hygienic problem.[...]

Anaerobic decomposition of cellulose is carried out only by bacteria (for example, Bacillus Omelyansky), and aerobic decomposition is carried out by many types of bacteria, fungi, and actinomycetes. [...]

The bacteria contain 1-4% fat, 8-14% protein and 80-85% water. Micro quantities contain phosphorus, potassium, calcium, magnesium, iron and other elements. Viruses do not have a cellular structure and have a size of 10-100 nm.[...]

However, different types of spore-forming bacteria have different attitudes towards sources of nitrogen nutrition. For example, cultures of the hay and potato bacillus group ferment carbohydrates more vigorously with the formation of various intermediate compounds. For the most common types of spore-forming bacteria, the best sources of nitrogen nutrition were peptone, casein hydrolysate, yeast autolysate and urea.[...]

Currently, ways to rationally produce and use cultures of virulent bacteria and entomopathogenic fungi to exterminate harmful insects are being studied. Of the mushrooms, one can name as an example the white muskardine (Beauveria bassiana Bals, and other species of this genus), the crops of which destroy many insects.[...]

Characteristic feature adhesion of microorganisms is selectivity and specificity. Representatives of the genera Micrococcus, Pseudomonas, Frivioc have the greatest tendency to adhesion; bacilli and streptomycetes have the least tendency. Requirements for carriers for the immobilization of microorganisms include their mechanical strength during prolonged use. Below are examples of the use of carriers of various natures for the immobilization of microorganisms.[...]

The essence of the disinfecting effect of chlorine is the chlorination and oxidation of substances included in the protoplasm of bacterial cells, which leads to their death. The most sensitive to chlorine are typhoid bacilli, dysentery and vibrio cholera.[...]

The pronounced enzymatic properties of some types of spore-forming bacteria cause the development of rot and browning of fruits, fruits and other plant products. Under favorable conditions for the reproduction of certain types of bacilli - producers of phospholipases and other enzymes - food spoilage is caused, which can cause gastroenteritis and other food poisoning. [...]

The released oxygen atom oxidizes the substances that make up the protoplasm of bacterial cells, as a result of which the microbes die. Chlorine also acts directly on bacteria in the same way. The most sensitive to chlorine are the typhoid, dysentery and cholera bacilli. However, chlorination does not completely sterilize water. There remain single, viable chlorine-resistant individuals.[...]

Bacteria are single-celled organisms several micrometers in size1. Based on their shape, they are classified into spherical (cocci), cylindrical and convoluted, as well as transitional ones between them. Cylindrical bacteria that form spores inside the cell are called bacilli; not forming spores - actually bacteria. Among the convoluted bacteria, vibrios, spirillum and spirochetes are distinguished (Fig. 9). There are more complex shapes bacteria - filamentous, myxobacteria.[...]

Of the 78 species that made up the activated sludge biocenosis at the beginning of the experiment, only 27 species adapted to halophilic conditions, the rest died. They were replaced by 12 new species.[...]

Ozone as a disinfectant is 15-20 times faster than chlorine. It has been established that the causative agent of infantile paralysis, the polio virus, dies under the influence of 0.45 mg/l of ozone after 2 minutes, while chlorine has the same effect only after 3 hours at a dose of 1 mg/l. When treating water with ozone, spores and bacilli of purulent inflammation die after 10 minutes, typhus and cholera pathogens die after 2 minutes.[...]

Representatives of the genus Bacillus showed significant differences in the action of proteases. Some of them achieved Pseudo-monas activity, as for you. methanicus, then its activity was significantly lower. The activity of the culture fluid changed accordingly. Under halophilic conditions, the protease activity of bacilli cells decreased slightly.[...]

Wastewater rich in salts of a certain composition destroys concrete and other Construction Materials, especially iron. In the case of the presence of sulfates, the concentration of which exceeds 300 mg/l SO3, sulfites and sulfides, the destructive effect can be attributed to the so-called. gypsum formation and the appearance of “cement bacillus” (calcium sulfoaluminate). As a result of hydrolytic cleavage, iron sulfate forms free sulfuric acid, which destroys concrete structures. Chlorides alkali metals and calcium are harmless if their concentration does not exceed 5000 mg/l. On the contrary, magnesium chloride in concentrations above 300 mg/l MO (and other magnesium salts), as well as ferric chloride, dissolve the lime of concrete. Nitrates are harmful only if they are present together with large quantities of ammonium salts. Therefore, when discharging such wastewater into sewers, it is necessary to pay special attention to the ratio of the quantities of industrial and urban waters, as well as the total concentration of dissolved substances. If the concentration of sulfates exceeds 500 mg/l, then the total gas yield during sludge decay decreases, and the hydrogen sulfide content increases.[...]

Some results of experiments on long-term stored water with natural contamination and additionally infected with cultures of Escherichia coli and staphylococcus, presented in Table. 5.7, indicate the high efficiency of inactivation of vegetative forms of microorganisms. When the bacterial contamination of long-term stored water with spores of anthracoid bacilli was 3.3 105 H - 6.2-106, the disinfection efficiency was 98.07 - 99.98%. A low-power electric discharge followed by filtration provides not only high efficiency of disinfection of long-term stored water, but also improvement of its organoleptic and chemical quality indicators to the requirements of GOST 2874-82. Thus, when processing model long-term stored water in an ERMM unit with a capacity of 6 l/h, turbidity decreases from 3.5-15.0 to 0.24-1.3 mg/l, color - from 404-70 to 5h-6 deg ., iron content - from 1.04-3.5 to 0.1 0.15 mg/l.[...]

The formation of the microflora of the digester occurs due to microorganisms that come with wastewater or sediment. In terms of species composition, the biocenosis of digesters is much poorer than aerobic biocenoses; only about 50 species of bacteria have been isolated from them that are capable of carrying out the first stage of the breakdown of contaminants - the stage of acid formation. Along with obligate anaerobes, facultative anaerobes can also be found in the digester. The total number of bacteria in the sediment ranges from 1 to 15 mg/ml. The final product of the fermentation process of this group of microorganisms is lower fatty acids, carbon dioxide, ammonium ions, hydrogen sulfide.[...]

Heat deficiency, more pronounced in the active soil layer of the WPO, affects both the nature of the biological treatment process and the formation of microbial cenoses. The natural change in microbial associations established by E. N. Mishustin for the soil also manifests itself in irrigated agricultural fields. During the first phases of decomposition organic matter fungi and non-spore-forming bacteria develop on them. Later, the number of bacilli and actinomycetes increases. There is also a change in the types of mushrooms. In activated sludge and biofilm, this pattern is not so pronounced. Here the nature of the microflora is more strongly affected by the specific transformation of various organic compounds.[ ...]

Thiamine (vitamin B1) is an important growth factor for staphylococci, streptococci, and leptospira. Thiamine is added to media for growing those microorganisms that are not able to synthesize it independently or only partially have this ability, for example, lactic acid microorganisms (M. Stephenson, 1951) or some pathogenic ones. Riboflavin (vitamin B2) is necessary for the normal biochemical activity of hemolytic streptococci, tetanus bacilli, lactic acid and propionic acid bacteria. Pantothenic acid (vitamin B3) and its derivatives are growth factors for pathogenic and non-pathogenic microorganisms. Most microorganisms do not need choline (vitamin B4), since in the process of evolution they have adapted to its synthesis.[...]

To decide which intestinal bacteria to give preference to as a sanitary indicator, it is important to compare their survival time in water with the survival time of pathogenic bacteria. You. re g ePV persists in the form of intestinal spores for a very long time; this period is much longer than the possible survival time of pathogenic microbes. Therefore, although the presence of you. regGppdepz indicates that fecal contamination of the substrate occurred at some point; it does not allow one to judge its freshness. Enterococcus, in contrast to the spore bacilli of the intestine, is not very stable in the external environment, and some pathogens of intestinal infections can survive it in water. As a result, although enterococcus is a reliable indicator of fresh fecal contamination, its absence in the test water does not guarantee complete epidemiological well-being.[...]

Paraffin (alkanes) and naphthenic hydrocarbons (cycloalkanes) make up from 56 to 92% of the petroleum products that pollute the effluents of the first and second sewerage systems. The main pollutants are oil distillation, cracking, hydrogenation purification, and reforming installations. The composition of paraffin and naphthenic hydrocarbons is very diverse and depends on the field of oil being processed. Oils from the eastern regions of the USSR contain more paraffinic hydrocarbons, while oil from Baku contains more naphthenic hydrocarbons. The composition of biological oxidants populating activated sludge is equally diverse. The biocenoses are dominated by bacteria and pseudomonads, corynebacteria, mycobacteria, actinomycetes and bacilli.

BACILLES

Rod-shaped bacteria. They live in water, soil, and the digestive tract of animals and humans. Many (E. coli, etc.) are involved in digestion, some (pathogens) are causative agents of infectious diseases. With sufficiently high immunity, the latter do not cause signs of illness in a person, but he secretes bacilli during external environment(bacillus carriage). Under unfavorable conditions, bacilli form spores that retain pathogenic properties for decades. Non-spore-forming gram-positive rods (lactobacillus), which cause lactic acid fermentation, are used for the production of fermented milk products.
