Bacteriophage Key words: bacteriophage, antibiotics, therapy, antibacterial-phage therapy,

Bacteriophage Bacteriophage, dysenteri, polyvalente 1,2,3,4,6 serotypes. Bacteriophage for therapy and prevention of dysentery. Shigellosis, also known as bacillary dysentery or Marlow syndrome, in its most severe manifestation, is

a foodborne illness caused by infection by bacteria of the genus Shigella. Shigellosis rarely occurs in animals other than humans Shigella sonnae, flexneri Shigella species are classified by four serogroups: Serogroup A: S. dysenteriae (15 serotypes) Serogroup B: S. flexneri (six serotypes) Serogroup C: S. boydii (19 serotypes) Serogroup D: S. sonnei (one serotype)

Bacteriophage therapy. Groups A–C are physiologically similar; S. sonnei (group D) can be differentiated on the basis of biochemical metabolism assays.

Three Shigella groups are the major disease-causing species: S. flexneri is the most frequently isolated species worldwide, and accounts for 60% of cases in the developing world; S. sonnei causes 77% of cases in the developed world, compared to only 15% of cases in the developing world; and S. dysenteriae is usually the cause of epidemics of dysentery, particularly in confined populations such as refugee camps.

Each of the Shigella genomes includes a virulence plasmid that encodes conserved primary virulence determinants. The Shigella chromosomes share most of their genes with those of E. coli K12 strain MG1655.

  

Bacteriophage Bacteriphage to salmonella group ABCDE Salmonella Serogroups A,В,С,D,E. Salmonellosis is an infection caused by Salmonella bacteria. Most people infected with Salmonella develop diarrhea, fever, vomiting, and abdominal cramps 12 to 72 hours after infection. In most cases, the illness lasts four to seven days, and most people recover without treatment. In some cases, the diarrhea may be so severe that the patient becomes dangerously dehydrated and must be hospitalized.

Salmonellosis is a major cause of bacterial enteric illness in both humans and animals. Each year an estimated 1.4 million cases of salmonellosis occur among humans in the United States.

Bacteriophage Bacteriophage to Salmonella enterica typhi. Therapy and prophylaxis.Worldwide, typhoid fever affects roughly 17 million people annually, causing nearly 600,000 deaths. The causative agent, Salmonella enterica typhi (referred to as Salmonella typhi. Infection of S. typhi leads to the development of typhoid, or enteric fever. This disease is characterized by the sudden onset of a sustained and systemic fever, severe headache, nausea.

Other symptoms include constipation or diarrhea, enlargement of the spleen, possible development of meningitis, and/or general malaise.

Untreated typhoid fever cases result in mortality rates ranging from 12-30% while treated cases allow for 99% survival.

Bacteriophage Bacteriophage to Stapyilococcus aureus. Staphylococcus aureus is a gram-positive coccal bacterium that is a member of the Firmicutes, and is frequently found in the nose,respiratory tract, and on the skin. It is often positive for catalase and nitrate reduction. Although S. aureus is not always pathogenic, it is a common cause of skin infections such as abscesses, respiratory infections such as sinusitis, and food poisoning. Pathogenic strains often promote infections by producing potent protein toxins, and expressing cell-surface proteins that bind and inactivate antibodies. The emergence of antibiotic-resistant strains of S. aureus such as methicillin-resistant S. aureus (MRSA) is a worldwide problem in clinical medicine.

Bacteriophage to staphylococcus.

Bacteriophage to staphylococcus. Staphylococcus can cause a wide variety of diseases in humans and animals through either toxin production or penetration. Staphylococcal toxins are a common cause of food poisoning, for they can be produced by bacteria growing in improperly stored food items. The most common sialadenitis is caused by staphylococci, as bacterial infections.

Bacteriophage to staph infections Treatment and prevention of purulent infections of the skin , mucous membranes, coagulase-negative staphylococci caused by staphylococci , as well as dysbacteriosis.

Bacteriophage is used to treat cystitis , cholecystitis , acute tonsillitis , enterocolitis , and others .

Bacteriophage Bacteriophage to Echerechia coli. Бактериофаг коли, Энтеропатогенная Echerichia coli. Escherichia coli (/ˌɛʃəˈrɪkiə ˈkoʊlɪ/ Anglicized to /ˌɛʃəˈrɪkiə ˈkoʊlaɪ/; commonly abbreviated E. coli) is a gram-negative, rod-shapedbacterium that is commonly found in the lower intestine of warm-blooded organisms (endotherms).

Most E. coli strains are harmless, but some serotypes are pathogenic and can cause serious infections or  food poisoning in humans, and are occasionally responsible for product recalls

Bacteriophage. Phage therapy—viruses that specifically target pathogenic bacteria—has been developed over the last 80 years, primarily in the former Soviet Union, where it was used to prevent diarrhea caused by E. coli.

 Presently, phage therapy for humans is available only at the Phage Therapy Center in the Republic of Georgia and in Poland.

 However, on January 2, 2007, the United States FDA gave Omnilytics approval to apply its E. coli O157:H7 killing phage in a mist, spray or wash on live animals that will be slaughtered for human consumption.

 The enterobacteria phage T4, a highly studied phage, targets E. coli for infection.

Bacteriophage. E.coli infections: Pathogenic E.coli strains can be categorized based on elements that can elicit an immune response in animals, namely:

O antigen: part of lipopolysaccharide layer K antigen: capsule H antigen: flagellin For example, E.coli strain EDL933 is of the O157:H7 group

Bacteriophage therapy. Enterotoxigenic E. coli (ETEC) causative agent of diarrhea (without fever) in humans, pigs, sheep, goats, cattle, dogs, and horses.

ETEC uses fimbrial adhesins (projections from the bacterial cell surface) to bind enterocyte cells in the small intestine. ETEC can produce two proteinaceous enterotoxins: The larger of the two proteins, LT enterotoxin, is similar to cholera toxin in structure and function.

The smaller protein, ST enterotoxin causes cGMP accumulation in the target cells and a subsequent secretion of fluid and electrolytes into the intestinal lumen.

ETEC strains are non-invasive, and they do not leave the intestinal lumen. ETEC is the leading bacterial cause of diarrhea in children in the developing world, as well as the most common cause of traveler's diarrhea. Each year, ETEC causes more than 200 million cases of diarrhea and 380,000 deaths, mostly in children in developing countries. https://en.wikipedia.org/wiki/Pathogenic_Escherichia_coli#Serotypes

Bacteriophage therapy. Enteropathogenic E. coli (EPEC) , causative agent of diarrhea in humans, rabbits, dogs, cats and horses.

Like ETEC, EPEC also causes diarrhea, but the molecular mechanisms of colonization and aetiology are different. EPEC lack ST and LT toxins, but they use an adhesin known as intimin to bind host intestinal cells. This virotype has an array of virulence factors that are similar to those found in Shigella, and may possess a shiga toxin. Adherence to the intestinal mucosa causes a rearrangement ofactin in the host cell, causing significant deformation. EPEC cells are moderately invasive (i.e. they enter host cells) and elicit an inflammatory response. Changes in intestinal cell ultrastructure due to "attachment and effacement" is likely the prime cause of diarrhea in those afflicted with EPEC. https://en.wikipedia.org/wiki/Pathogenic_Escherichia_coli#Serotypes

Bacteriophage therapy. Enteroinvasive E. coli (EIEC) . EIEC infection causes a syndrome that is identical to shigellosis, with profuse diarrhea and high fever.

The most infamous member of this virotype is strain O157:H7, which causes bloody diarrhea and no fever. EHEC can cause hemolytic-uremic syndrome and sudden kidney failure. It uses bacterial fimbriae for attachment (E. coli common pilus, ECP), is moderately invasive and possesses a phage-encoded shiga toxin that can elicit an intense inflammatory response.

https://en.wikipedia.org/wiki/Pathogenic_Escherichia_coli#Serotypes

Bacteriophage therapy. Enteroaggregative E. coli (EAEC) so named because they have fimbriae which aggregate tissue culture cells, EAEC bind to the intestinal mucosa to cause watery diarrhea without fever. EAEC are non-invasive. They produce a hemolysin and an ST enterotoxin similar to that of ETEC.

Bacteriophage therapy Adherent-Invasive E. coli (AIEC) AIEC are able to invade intestinal epithelial cells and replicate intracellularly. It is likely that AIEC are able to proliferate more effectively in hosts with defective innate immunity. They are associated with the ileal mucosa in Crohn's disease.

Bacteriophage therapy. Enterohemorrhagic E. coli (EHEC) . The most infamous member of this virotype is strain O157:H7, which causes bloody diarrhea and no fever. EHEC can cause hemolytic-uremic syndrome and sudden kidney failure. It uses bacterial fimbriae for attachment (E. coli common pilus, ECP),[19] is moderately invasive and possesses a phage-encoded shiga toxin that can elicit an intense inflammatory response.

Bacteriophage Bacteriophage to Pseudomonas aeruginosa. Pseudomonas aeruginosa is a common Gram-negative, rod-shaped bacterium that can cause disease in plants and animals, including humans.

A species of considerable medical importance, P. aeruginosa is a prototypical "multidrug resistant (MDR) pathogen" recognised for its ubiquity, its intrinsically advanced antibiotic resistance mechanisms, and its association with serious illnesses – especially nosocomial infections such as ventilator-associated pneumonia and various sepsis syndromes.

BacteriophageBacteriophage to Klebsiella pneumoniae. Klebsiella pneumoniae is a Gram-negative, nonmotile, encapsulated, lactose-fermenting, facultative anaerobic, rod- shapedbacterium.

Klebsiella appears as a mucoid lactose fermenter on MacConkey agar. Although found in the normal flora of the mouth, skin, and intestines, it can cause destructive changes to human and animal lungs if aspirated (inhaled), specifically to the alveoli (in the lungs) resulting in bloody sputum. In the clinical setting, it is the most significant member of the Klebsiella genus of Enterobacteriaceae. K. oxytoca and K. rhinoscleromatis have also been demonstrated in human clinical specimens. In recent years, Klebsiella species have become important pathogens in nosocomial infections.
