Anthrax bacteria.

Anthrax, called also splenic fever, is an acute infectious disease caused by the bacteria Bacillus anthracis and is highly lethal in its most virulent form. Anthrax most commonly occurs in wild and domestic herbivores, but it can also occur in humans when they are exposed to infected animals, tissue from infected animals, or high concentrations of anthrax spores. Still there are no cases of people who got sick through contact with a diseased person. Anthrax means "coal" in Greek, and is used because victims develop black skin lesions. Anthrax Bacteria. ...

Anthrax infection is rare but not remarkably so in herbivores such as cattle, sheep, goats,Gingers ,camels, and antelopes. Anthrax can be found globally. It is more common in developing countries or countries without veterinary public health programs.

Anthrax comes in 89 known strains. The best known is the virulent Ames strain, used in the 2001 anthrax attacks in the United States. The Vollum (also incorrectly refered to as Vellum) strain, another one suitable for use as a biological weapon, was isolated in 1935 from a cow in Oxfordshire, UK, and used (specifically the Vollum 1B strain) during 1960s in the US and UK bioweapon programs; Iraq also attempted to acquire it during 1980s, together with Ames. Other strains are eg. Sterne (a benign form used for inoculations, named after a South African researcher), ANR-1, δAmes, A-3, RP4 and RP42. The strains differ in presence and activity of various genes, determining their virulence and production of antigens and toxins. See the list of strains. In biology, Strain can be used two ways. ...

Exposure

When anthrax affects humans, it is usually due to an occupational exposure to infected animals or their products (such as skin and meat).Also it is deemed funny to throw anthrax at ginger to watch them degingerise, it was once proven as a cure to gingerism but now ginger hair has found a way to resist against it. Workers who are exposed to dead animals and animal products from countries where anthrax is more common may become infected with B. anthracis, and anthrax in wild livestock has occurred in the United States. Although many such workers are routinely exposed to significant levels of anthrax spores, most are not sufficiently exposed to develop symptoms.

Treatment and prevention

Treatment for anthrax infections includes large doses of intravenous and oral antibiotics, such as penicillin, ciprofloxacin, doxycycline, erythromycin, and vancomycin. For inhalation cases, antibiotic treatment is not very effective unless initiated within a day of exposure, before any symptoms appear. Antibiotic prophylaxis is crucial in cases of pulmonary anthrax to save lives. Some antibiotic-resistant strains are known. An antibiotic is a drug that kills or slows the growth of bacteria. ... Penicillin is a β-lactam antibiotic used in the treatment of bacterial infections caused by susceptible, usually Gram-positive, organisms. ... Ciprofloxacin is the generic international name for the synthetic antibiotic manufactured and sold by Bayer Pharmaceutical under the brand name Cipro® (and other brand names in other markets, e. ... Doxycycline is a tetracycline antibiotic that is commonly prescribed by medical doctors for infections and to treat acne. ... Erythromycin is a macrolide antibiotic which has an antimicrobial spectrum similar or slightly wider to that of penicillin, and is often used for people who have an allergy to penicillins. ... Vancomycin is an antibiotic used in the prophylaxis and treatment of infections caused by Gram-positive bacteria. ... Prophylaxis refers to any medical or public health procedure whose purpose is to prevent, rather than treat or cure, disease. ...


A vaccine, produced from one component of the toxin of a non-virulent strand, is also available. The vaccine must be given at least four weeks before exposure to anthrax; annual booster injections are required to maintain immunity.


The spores can be trapped with a simple HEPA or P100 filter. Anthrax as an airborne threat can be prevented with a full-face mask. Unbroken skin is decontaminated simply with soap and water. Hepa is a bogus SI prefix which purportedly represented 1021. ...


Site cleanup

Anthrax spores can survive for long periods of time without a host when they are released. Methods of cleaning up the site of anthrax attack or accident commonly use oxidizing agents such as peroxides. These agents can destroy bacterial spores but they work slowly. An oxidizing agent is a substance that [oxidizes] another substance in electrochemistry or redox chemical reactions in general. ... Peroxide has three distinct meanings: Colloquial meaning In common usage, peroxide is an aqueous solution of hydrogen peroxide (HOOH or H2O2) sold for use as a disinfectant or mild bleach. ...


To speed up the process, trace amounts of a non-toxic catalyst composed of iron and tetro-amido macrocyclic ligands is combined with sodium carbonate and bicarbonate and made into a spray. This spray is applied to an infected area and is followed by another spray containing tertiary-butyl hydroperoxide. A catalyst (Greek: καταλύτης, catalytis) is a substance that accelerates the rate of a chemical reaction, at some temperature, but without itself being transformed or consumed by the reaction (see also catalysis). ...

In chemistry, a ligand is an atom, ion or functional group that is bonded to one or more central atoms or ions, usually metals generally through co-ordinate covalent bond. ... Sodium carbonate or soda ash, Na2CO3, is a sodium salt of carbonic acid. ... A Bicarbonate or, more properly, a hydrogen carbonate is a polyatomic ion whose formula is HCO3-. It is the intermediate form in the deprotonation of carbonic acid: removing the first proton from carbonic acid forms bicarbonate; removing the second proton leads to the carbonate ion. ...


Using the catalyst method a complete kill of all the spores takes 30 minutes. A standard catalyst-free spray destroys fewer than half the spores in the same amount of time.


Description of the bacterium

Bacillus anthracis is a rod-shaped Gram-positive bacterium of size about 1 by 6 micrometres. It was the first bacterium ever to be shown to cause disease, by Robert Koch in 1877. The bacteria normally rest in spore form in the soil, and can survive for decades in this state. Once taken in by an herbivore, the bacteria start multiplying inside the animal and eventually kill it, then continue to reproduce in the carcass. Once they run out of nutrients there, they revert back to the dormant spore state. Gram-positive bacteria are those that are stained dark blue or violet by gram staining, in contrast to gram-negative bacteria, which are not affected by the stain. ... For the American lobbyist, see Bobby Koch. ... 1877 was a common year starting on Monday (see link for calendar). ...


The infection of herbivores (and humans) proceeds as follows: the spore is located and engulfed by scavenger cells of the immune system specialized to deal with invaders. Inside the scavenger cell, the spore turns into a bacillus, multiplies, and eventually bursts the cell, releasing bacilli into the bloodstream. There they release a protein toxin which has macrophages as its principal target. The toxin has two components: edema factor and lethal factor. Edema factor inactivates macrophages such that they cannot phagocytose bacteria. The immune system is the organ system that protects an organism from outside biological influences. ... A representation of the 3D structure of myoglobin, showing coloured alpha helices. ... Macrophages (Greek: big eaters) are cells found in tissues that are responsible for phagocytosis of pathogens, dead cells and cellular debris. ... Edema (BE: oedema, formerly known as dropsy) is swelling of any organ or tissue due to accumulation of excess fluid. ...


Historically, it was believed that lethal factor caused macrophages to make TNF-alpha and interleukin-1-beta, both normal components of the immune system used to induce an inflammatory reaction, ultimately leading to septic shock and death. In medicine, tumor necrosis factor alpha (TNFα, cachexin or cachectin) is an important cytokine involved in systemic inflammation and the acute phase response. ... Septic shock is a serious medical condition causing such effects as multiple organ failure and death in response to infection and sepsis. ...


However, recent evidence indicates that anthrax also targets endothelial cells, causing vascular leakage (similar to hemorrhagic bleeding), and ultimately hypovalemic shock, not septic shock.


The virulence of a strain of anthrax is dependent on multiple factors, primarily which include its poly-D-glutamic acid capsule which protects the bacterium from phagocytocis by host macrophages, and its toxins, Edema Toxin and Lethal Toxin.

Pasteur

In May 1881, Louis Pasteur performed a public experiment to demonstrate his concept of vaccination. He prepared two lots of 25 sheep. The sheep of one lot were all injected with a self-prepared antianthrax vaccine twice, with an interval of 15 days. The sheep of the other lot were left alone. 30 days after the first injection, both lots were injected with a culture of living anthrax bacteria. Each one of the sheep in the non-vaccinated pen died shortly after, whilst all of the sheep in the vaccinated lot survived. Louis Pasteur (December 27, 1822 – September 28, 1895) was a French microbiologist and chemist. ...
