Cutaneous anthrax is a zoonotic disease caused by the spore-forming bacterium Bacillus anthracis, which typically presents with ulcers after contact with animals or animal products, and is rarely seen in high-income countries but is common in those with low- and middle-incomes. Objective. The aim of this study is to show the main clinical characteristics of cutaneous anthrax in endemic areas.

With the anthrax threat becoming a reality, it is very important to have an effective way to sterilize areas contaminated by anthrax. Anthrax spores are the dormant form of the anthrax bacteria. They can germinate in tissues, producing new bacteria that release lethal toxins. Neutrons can be a powerful tool in our defense against anthrax contamination. Neutrons are elementary particles that have no charge, which allows them to be very penetrating, killing the anthrax spores on the surface and inside the containers. So neutrons have an advantage over other forms of radiation if deep penetration is required to kill biological organisms. A Cf neutron source allows for a low cost method of decontamination. It emits most neutrons in the 100 keV to 2 MeV energy regions, and a neutron in this energy region is 20 times more deadly than electrons or gamma rays in killing anthrax spores. If we just consider the first neutron collision with anthrax spores and that all the anthrax spores will not survive at the

The index case of inhalational anthrax in October 2001 was in a man who lived and worked in Florida. However, during the 3 days before illness onset, the patient had traveled through North Carolina, raising the possibility that exposure to Bacillus anthracis spores could have occurred there. The rapid response in North Carolina included surveillance among hospital intensive-care units, microbiology laboratories, medical examiners, and veterinarians, and site investigations at locations visited by the index patient to identify the naturally occurring or bioterrorism-related source of his exposure.

The U.S. Food and Drug Administration today approved a new indication for BioThrax (Anthrax Vaccine Adsorbed) to prevent disease following suspected or confirmed exposure to Bacillus anthracis, the bacterium that causes anthrax disease. The vaccines new use is approved for people 18 through 65 years of age in conjunction with recommended antibiotic treatment. BioThrax was initially approved by the FDA in 1970 for the prevention of anthrax disease in persons at high risk of exposure.. Anthrax disease, especially the inhalation form, is often fatal if not promptly treated. Anthrax is considered one of the more likely agents to be used in a biological attack, primarily because its spores are very stable and easy to disperse. Although it is rare, people may contract anthrax disease through natural exposures, such as contact with infected animals or contaminated animal products.. With todays approval of BioThrax, we now have a vaccine that can be used, together with antibiotic treatment, to ...

In October 2001, four cases of inhalational anthrax occurred in workers in a Washington, D.C., mail facility that processed envelopes containing Bacillus anthracis spores. We reviewed the envelopes paths and obtained exposure histories and nasal swab cultures from postal workers. Environmental sampling was performed. A sample of employees was assessed for antibody concentrations to B. anthracis protective antigen. Case-patients worked on nonoverlapping shifts throughout the facility, suggesting multiple aerosolization events. Environmental sampling showed diffuse contamination of the facility. Potential workplace exposures were similar for the case-patients and the sample of workers. All nasal swab cultures and serum antibody tests were negative. Available tools could not identify subgroups of employees at higher risk for exposure or disease. Prophylaxis was necessary for all employees. To protect postal workers against bioterrorism, measures to reduce the risk of occupational exposure are ...

Anthrax bacteria. Coloured transmission electron micrograph (TEM) of anthrax (Bacillus anthracis) bacteria (yellow) cultured from a blood sample. Seen here are endospores (pink ovals within bacterial cells) and free spores (pink ovals). The spores are reproductive cells that are able to survive dormant in unfavourable conditions for long periods of time. B. anthracis is the cause of anthrax. It can infect the skin (cutaneous anthrax), causing raised itchy lesions, the lungs (pulmonary anthrax), which is fatal unless treated quickly, and the digestive system (gastrointestinal anthrax), causing vomiting of blood and severe diarrhoea. All forms can be fatal if left untreated. Treatment is with antibiotics. Magnification: x9300, when printed 10 centimetres tall. - Stock Image C020/8537

TREATMENT - ANTHRAX from emedicine.com A number of possible therapeutic strategies have yet to be fully explored experimentally or submitted for approval to the Food and Drug Administration (FDA). The recommendations provided do not represent uses currently approved by the FDA but are a consensus based on best available information of recent studies. Given the fulminant course of inhalation anthrax, early antibiotic administration is essential to maximize patient survival. Given the difficulty in achieving timely microbiologic diagnosis of anthrax, all persons with fever or evidence of systemic disease in an area where anthrax cases are occurring should be treated empirically for anthrax until the disease is excluded. No clinical studies exist of the treatment of inhalation anthrax in humans. Most naturally occurring strains of anthrax are sensitive to penicillin, and penicillin historically has been the preferred therapy for the treatment of anthrax. Penicillin and doxycycline are FDA-approved ...

Inhalational anthrax is the most serious form of anthrax infection, seen in the cases in Florida and Washington DC. The disease begins when aerosolized anthrax spores are inhaled. Once in the lungs, immune systems cells called macrophages, whose normal function is to ingest, kill, and degrade invading pathogens and activate other immune system cells. However, instead of being killed, the spores reactivate and grow into live bacterial cells. The macrophages transport the bacteria to the lymph nodes, where they proliferate and spread, eventually breaking out of the lymph system into the bloodstream. During this period of lymphatic replication, the patient only displays non-specific symptoms much like the flu. Once in the bloodstream, the bacteria proliferate further and begin producing anthrax toxin. Eventually the bacteria spread through the entire circulatory system at high concentrations. Death from inhalational anthrax is associated with shock and multiple organ failure. When untreated, ...

Bacillus anthracis (anthrax) infection is rarely diagnosed in Romania, cases being sporadic, coming especially from the agrarian environment. Anthrax is a zoonotic infection, and humans are incidental hosts. Early nonspecific symptomatology makes detection of anthrax cases difficult, but compete anamnesis related to patient activity or exposure to animal products can raise suspicion of anthrax. A patient with a clinical suspicion of bacillus anthracis infection should receive an effective treatment very quickly to avoid neurological complications that have a high death rate.

It was reported that the people had anthrax-like small blisters or bumps on their hands and arms after eating the meat.. It was reported that 30 villagers had consumed the meat in question, but most of them had already taken medicine and they could not be successfully tested for anthrax. Instead, the hospital team collected samples from animal carcasses for lab tests with the results expected soon.. The country has been free of livestock anthrax since 2000 and the last anthrax outbreak in Thailand was 17 years ago.. According to the Merck Veterinary Manual, Anthrax is a zoonotic disease caused by the spore-forming bacterium Bacillus anthracis. Anthrax is most common in wild and domestic animals but can also be seen in humans exposed to tissue from infected animals, contaminated animal products or directly to B anthracis spores under certain conditions..

In February 2002, scientist Bruce Ivins submitted a sample of the anthrax he has been using to FBI investigators, but it was destroyed because it was not submitted according to strict protocols. As a result, he is asked to submit a second sample in April 2002, and does. Ivins works at USAMRIID, the US Armys top bioweapons laboratory, and is helping with the anthrax investigation even as the FBI has reason to believe the anthrax could have come from USAMRIID (see Mid-October 2001 and Winter 2001). Ivins is using a variety of the Ames anthrax strain known as RMR-1029. Around early 2004, scientists will discover some unique genetic markers to the anthrax used in the 2001 attacks and will start comparing that anthrax to other anthrax. No match will be found between Ivinss April 2002 sample and the anthrax used in the attacks. As a result of this discrepancy, the FBI will raid Ivinss lab in July 2004 and seize more samples of RMR-1029 (see July 16, 2004). Additionally, Paul Keim, a biologist at ...

Anthrax is a bacterial disease of man and animals caused by the bacteria Bacillus anthracis. Anthrax bacteria form spores, which are extremely stable in the environment. There are three clinical presentations of the disease: 1) Cutaneous infections, the mildest form, occur when bacterial spores become embedded in the skin. 2) The gastrointestinal form, which is extremely rare, occurs when animals ill with anthrax are consumed as food. 3) Inhalation anthrax occurs when the spores are inhaled. Both the inhalation and gastrointestinal forms have high mortality rates. The reservoir of the bacteria is soil, where the spores can remain viable for years. The spores can be found worldwide and are found naturally in some western states in the U.S. and Canada. Animals, including livestock, can acquire the bacteria from contaminated soil. However, there have been no reported cases of anthrax in Indiana livestock since before 1960.. Anthrax is a disease of interest because of its high mortality rate, severe ...

Their findings, which appeared online today in Nature, are based on testing in mice. However, the results may contribute to the development of anthrax treatments for humans, the researchers say.. Anthrax disease is caused by the bacterium Bacillus anthracis, which produces two deadly toxins: lethal toxin and edema toxin. When B. anthracis infects a human or animal, both toxins seek out and bind to receptors on the surfaces of human and animal cells. Using two types of laboratory mice-those missing the anthrax toxin receptor on a single type of cell or those having the receptor present on a single type of cell-the scientists compared disease progression among the rodents. They concluded that anthrax-induced death is caused primarily by lethal toxin targeting heart cells and muscle cells surrounding blood vessels, and edema toxin targeting liver cells.. These results may help scientists studying anthrax disease in humans. For example, the study authors suggest, knowing the types of cells that ...

Until 2001, Bacillus anthracis, the bacterium that causes anthrax, was an obscure agricultural pathogen, but that fall someone sent letters stuffed with anthrax spores to several politicians and journalists. Nearly half (5/11) of those infected by breathing in the spores died from the disease. The anthrax mailings triggered a run on antibiotics, but these drugs only work in the early stages of anthrax infection, before the bacteria have had time to spread and secrete toxins. These attacks called attention to the need for better therapies for anthrax infection, said Tang ...

Since the last report (1), six new anthrax cases have been reported. Three of these cases have occupational exposures similar to previously reported cases (1). A fourth case occurred in a mail handler at a facility not previously linked to cases but that receives mail from a facility at which cases have occurred previously. Two new cases have no discernable epidemiologic link with anthrax cases previously reported or sites that are associated with known cases. These new cases suggest that anthrax exposure has occurred or is continuing to occur through means that cannot be ascribed to known contaminated letters or the paths these letters took through the mail service. The public health response to these new anthrax cases will evolve based on ongoing epidemiologic and criminal investigations. Because exposures are being intentionally perpetrated, public health authorities must be vigilant for the appearance of new cases in previously unaffected populations. Prompt data sharing between law ...

TY - JOUR. T1 - Molecular determinants for a cardiovascular collapse in anthrax. AU - Brojatsch, Jurgen. AU - Casadevall, Arturo. AU - Goldman, David L.. PY - 2014/1/1. Y1 - 2014/1/1. N2 - Bacillus anthracis releases two bipartite proteins, lethal toxin and edema factor, that contribute significantly to the progression of anthrax-associated shock. As blocking the anthrax toxins prevents disease, the toxins are considered the main virulence factors of the bacterium. The anthrax bacterium and the anthrax toxins trigger multiorgan failure associated with enhanced vascular permeability, hemorrhage and cardiac dysfunction in animal challenge models. A recent study using mice that either lacked the anthrax toxin receptor in specific cells and corresponding mice expressing the receptor in specific cell types demonstrated that cardiovascular cells are critical for disease mediated by anthrax lethal toxin. These studies are consistent with involvement of the cardiovascular system, and with an increase of ...

A new anthrax antibody engineered by scientists at The University of Texas at Austin protects and defends against inhalation anthrax without the use of antibiotics and other more expensive antibodies. The high-affinity antibody, an anthrax antitoxin, successfully eliminated both anthrax bacteria and its deadly toxins in animal tests. If future tests concur, this could be the first successful treatment for late-stage anthrax infection, even for an anthrax strain that has been designed to resist antibiotics.

Anthrax is an acute infectious disease caused by the spore-forming bacterium Bacillus anthracis (B. anthracis). B. anthracis spores are highly infective and can cause inhalation, cutaneous, or gastrointestinal anthrax. Inhalation anthrax results from breathing in spores and is of great concern due to its high fatality rate.

Anti-angiogenic therapies are effective for the treatment of cancer, a variety of ocular diseases, and have potential benefits in cardiovascular disease, arthritis, and psoriasis. We have previously shown that anthrax protective antigen (PA), a non-pathogenic component of anthrax toxin, is an inhibitor of angiogenesis, apparently as a result of interaction with the cell surface receptors capillary morphogenesis gene 2 (CMG2) protein and tumor endothelial marker 8 (TEM8). Hence, molecules that bind the anthrax toxin receptors may be effective to slow or halt pathological vascular growth. Here we describe development and testing of an effective homogeneous steady-state fluorescence resonance energy transfer (FRET) high throughput screening assay designed to identify molecules that inhibit binding of PA to CMG2. Molecules identified in the screen can serve as potential lead compounds for the development of anti-angiogenic and anti-anthrax therapies. The assay to screen for inhibitors of this protein

In the United States, incidence of naturally-acquired anthrax is extremely rare (about 1-2 cases of cutaneous disease per year). Gastrointestinal anthrax is rare, but may occur as explosive outbreaks associated with ingestion of infected animals. Worldwide, the incidence is unknown, though B. anthracis is present in most of the world. Unreliable reporting makes it difficult to estimate the true incidence of human anthrax worldwide. However, in fall 2001, 22 cases of anthrax (11 inhalation, 11 cutaneous) were identified in the United States following intentional contamination of the mail. In the United States, the annual occurrences of naturally-occurring human anthrax declined from estimated 130 cases annually in the early 1900s to 2 cases each in 2000, 2001, and 2002 ...

Spores of Bacillus anthracis have for long been regarded as one of the most powerful bioterrorism threats due to their stability and high lethality [1]. The spores can be easily produced and stockpiled in large quantities, using simple microbial techniques by people having access to a virulent strain and incentive to be exposed to the risk connected with its propagation and handling. Previous deliberate spread of anthrax spores as agent of biowarfare has been as aerosol. However, they could also be disseminated through the food or water supply for targeting of the gastrointestinal tract.. Anthrax infections fall into three different categories, reflecting the route of entry; inhalational, gastrointestinal or cutaneous in order of severity of the infection. With regard to bioterrorism, the most realistic mode of mass exposure includes inhalational or gastrointestinal infections. Conceptually, the idea of targeting the food supply is not new [2] and a few records of planned use of anthrax spores ...

Anthrax toxin is a three-protein exotoxin secreted by virulent strains of the bacterium, Bacillus anthracis-the causative agent of anthrax. The toxin was first discovered by Harry Smith in 1954. Anthrax toxin is composed of a cell-binding protein, known as protective antigen (PA), and two enzyme components, called edema factor (EF) and lethal factor (LF). These three protein components act together to impart their physiological effects. Assembled complexes containing the toxin components are endocytosed. In the endosome, the enzymatic components of the toxin translocate into the cytoplasm of a target cell. Once in the cytosol, the enzymatic components of the toxin disrupts various immune cell functions, namely cellular signaling and cell migration. The toxin may even induce cell lysis, as is observed for macrophage cells. Anthrax toxin allows the bacteria to evade the immune system, proliferate, and ultimately kill the host animal. Research on anthrax toxin also provides insight into the ...

Eleven known cases of bioterrorism-related inhalational anthrax (IA) were treated in the United States during 2001. We retrospectively compared 2 methods that have been proposed to screen for IA [1, 2]. The 2 screening protocols for IA were applied to the emergency department charts of patients who presented with possible signs or symptoms of IA at Inova Fairfax Hospital (Falls Church, Virginia) from 20 October 2001 through 3 November 2001. The Mayer criteria [1] would have screened 4 patients (0.4%; 95% CI, 0.1%-0.9%) and generated charges of $1900. If 29 patients (2.6%; 95% CI, 1.7%-3.7%) with ⩾5 symptoms (but without fever and tachycardia) were screened, charges were $13,325. The Hupert criteria [2] would have screened 273 patients (24%; 95% CI, 22%-27%) and generated charges of $126,025. In this outbreak of bioterrorism-related IA, applying the Mayer criteria would have identified both patients with IA and would have generated fewer charges than applying the Hupert criteria.. ...

In a newly published study, researchers from MIT show that a modified version of the anthrax toxin can be used to deliver antibody drugs to kill cancer cells.. Bacillus anthracis bacteria have very efficient machinery for injecting toxic proteins into cells, leading to the potentially deadly infection known as anthrax. A team of MIT researchers has now hijacked that delivery system for a different purpose: administering cancer drugs.. Anthrax toxin is a professional at delivering large enzymes into cells, says Bradley Pentelute, the Pfizer-Laubauch Career Development Assistant Professor of Chemistry at MIT. We wondered if we could render anthrax toxin nontoxic, and use it as a platform to deliver antibody drugs into cells.. In a paper appearing in the journal ChemBioChem, Pentelute and colleagues showed that they could use this disarmed version of the anthrax toxin to deliver two proteins known as antibody mimics, which can kill cancer cells by disrupting specific proteins inside the cells. ...

Washington Two Washington-area postal workers have been diagnosed with inhalation anthrax and two more employees at the same facility have died of symptoms consistent with the disease, officials said Monday as the nation grappled with an unprecedented bioterrorism threat.. Dr. Ivan Walks, the citys chief health official, also said authorities are investigating as many as nine more cases that have aroused concern. He said he did not know how many of the nine were postal workers or how many were hospitalized.. The disclosures came as postal workers by the dozens lined up for testing, and city authorities urged anyone connected with the affected Brentwood central mail facility to come forward immediately for screening.. This is a different day, the city health official said at a news conference.. He said the unidentified man diagnosed with the disease was hospitalized in suburban Virginia, at the same facility where another postal worker was diagnosed over the weekend.. He said authorities were ...

human) RATIONALE FOR SURVEILLANCE Anthrax is a widespread zoonosis transmitted from domestic animals (cattle, sheep, goats, buffaloes, pigs and other) to humans by direct contact or through animal products. Human anthrax is a serious problem in several countries and has potential for explosive outbreaks (especially the gastrointestinal form); while pulmonary (inhalation) anthrax is mainly occupational, the threat of biological warfare attacks should not be forgotten. Anthrax has a serious impact on the trade of animal products. The control of anthrax is based on its prevention in livestock: programmes based only on prevention in humans are costly and likely to be ineffective except for those industrially exposed. There is an effective vaccine for those occupationally exposed, and successful vaccines for livestock, particularly for herds with ongoing exposure to contaminated soil. In most countries anthrax is a notifiable disease. Surveillance is important to monitor the control programmes and to ...

MONDAY, March 21, 2016 (HealthDay News) -- Anthim (obiltoxaximab) has been approved by the U.S. Food and Drug Administration to treat inhalational anthrax, a rare disease stemming from infected animal products. Bacillus anthracis spores also pose a deadly bioterrorism threat if released intentionally.. Anthrax toxins can cause severe tissue damage and death, the FDA said Monday in a news release. Anthim, combined with certain antibacterial drugs, is designed to neutralize the toxins. The medications effectiveness was evaluated in studies conducted on animals, since it wasnt ethical or feasible to conduct such trials with human volunteers, the agency said.. The drugs safety was evaluated in 320 healthy human volunteers. The most common side effects included headache, itching, upper respiratory tract infection, cough, nasal congestion, hives and injection-site reactions including swelling, bruising and pain.. Anthims label includes a boxed warning of a potential severe and possibly fatal ...

Weve had anthrax down here for over a hundred years, and Ive been around it all my life, said Randy Hicks, a salesman at the Uvalde Farm and Ranch Supply Company. I can tell you this much, Im sure not scared of it.. State officials said more than 1,600 animals died of anthrax in Texas this summer, the most severe outbreak of the disease since 1987. But no people have died. One man in Del Rio contracted cutaneous anthrax while skinning a buffalo in June, the first confirmed case among humans here since 1988. Another Del Rio man is believed to have contracted the disease but recovered before he could be tested, said Dr. Terry Conger, the states epidemiologist at the Texas Animal Health Commission.. Among Texas ranchers, anthrax is just another occupational hazard among many, like drought, low beef prices or coyotes, that can be managed through care and caution.. There has been anthrax around for as long as there have been people and animals, all the way back to the Bible, Mr. Conger said. ...

Background Anthrax toxin is comprised of protective antigen (PA), lethal factor (LF), and edema factor (EF). These proteins are individually nontoxic; however, when PA assembles with LF and EF, it produces lethal toxin and edema toxin, respectively. Assembly occurs either on cell surfaces or in plasma. In each milieu, PA assembles into a mixture of heptameric and octameric complexes that bind LF and EF. While octameric PA is the predominant form identified in plasma under physiological conditions (pH 7.4, 37°C), heptameric PA is more prevalent on cell surfaces. The difference between these two environments is that the anthrax toxin receptor (ANTXR) binds to PA on cell surfaces. It is known that the extracellular ANTXR domain serves to stabilize toxin complexes containing the PA heptamer by preventing premature PA channel formation-a process that inactivates the toxin. The role of ANTXR in PA oligomerization and in the stabilization of toxin complexes containing octameric PA are not understood.

The Centers for Disease Control and Prevention (CDC) recommends 60 days of oral antibiotics along with a three-dose regimen of BioThraxT anthrax vaccine (zero, two weeks, four weeks) as an emergency public health intervention for people exposed to anthrax. Ciprofloxacin (Cipro ) and doxycycline are approved in adults and children for post exposure prophylaxis (preventing infection in people exposed to anthrax). Levofloxacin (Levaquin ) is approved for post exposure prophylaxis in adults 18 and older. Common side effects of Cipro include upset stomach, vomiting, diarrhea, fatigue, dizziness, or headache. Patients taking doxycycline should be aware of the following side effects: upset stomach, vomiting, and diarrhea. Additionally, doxycycline and ciprofloxacin should not be taken with antacids, calcium supplements, and dairy products. These may bind with the medications, decreasing their effectiveness. Common side effects of Levaquin include nausea, vomiting, diarrhea, stomach pain, headache, ...

Maj. Gen. John Parker. [Source: Public domain]On October 25, 2001, Homeland Security Director Tom Ridge tells reporters that the anthrax used in a letter sent to Sen. Tom Daschle (D-SD) was highly concentrated and pure and that a binding material was used, resulting in small spore clusters that are more easily spread. In contrast, the anthrax in a letter sent to the New York Post was coarser and less concentrated. Both letters used the same Ames strain of anthrax bacterium. (The Post letter was part of a less sophisticated first wave of letters (see September 17-18, 2001) and the Daschle letter was from the second wave (see October 6-9, 2001).) On October 29, Major General John Parker, commanding general of USAMRIID, the US Armys top bioweapons laboratory, makes similar comments at a White House briefing. He says silica was found in the Daschle letter anthrax and the anthrax spore concentration in the Daschle letter was ten times that of the New York Post letter. The presence of a binding ...

It has been a while since the 2001 anthrax attacks but anthrax remains a potent bio-weapon that is notoriously hard to clean up. Anthrax spores can survive

As Vera and I pointed out to the Commission, and confirmed by CDCs Advisory Committee on Immunization Practices, after the anthrax letters between 10 and 30 thousand people potentially exposed to anthrax spores took antibiotics. Not a single one developed anthrax. One hundred ninety-eight also took vaccine. They failed to get anthrax. Does vaccine improve the effect of antibiotics? It is impossible to improve on 100% protection, though the Commission would like us to forget this human efficacy experiment. If you give the vaccine with something that is highly (100%) protective, the vaccine will naturally appear to be most effective under those circumstances. ...

Source: Washington Post, July 28, 2003. OPINION. Unready for Anthrax By Lawrence M. Wein and Edward H. Kaplan. In any attempted terrorist attack against this country, smallpox and anthrax would be the only two biological agents capable of causing mass casualties. And while the government has invested considerable effort in planning for a potential smallpox attack, no equivalent plan exists for anthrax.. In a recently completed study, we looked into various emergency responses to an airborne anthrax attack and concluded that the United States is woefully unprepared. Two pounds of weapons-grade anthrax dropped on a large American city could result in more than 100,000 deaths, even if early cases were successfully diagnosed, antibiotics were distributed broadly and drug adherence was high. The reason for the catastrophic death toll: Not enough people would receive antibiotics quickly enough to prevent symptoms from developing, and those who developed symptoms would overwhelm the medical ...

The litany of mistakes that were made, detailed in the reports Findings, is breathtaking. Lack of understanding of anthrax. Lack of SOPs. Lack of appropriate experimental design. Failure to follow CDCs own protocols, where they existed. Lack of supervision. Lack of timely communication when the incident was discovered, including identifying employees who may have been exposed so they could receive prophylaxis. (See page 16 of the Report.) However, I disagree that it was highly unlikely that staff were exposed to anthrax: they were, more likely, simply not exposed to enough anthrax spores, along with receiving prophylactic antibiotics, to induce disease. ...

B. anthracis remains a bioterrorism threat, with the potential for thousands or tens of thousands to be exposed after spore release in a densely populated setting5,6,30,31. Such numbers of casualties would likely strain and possibly overwhelm the public health and medical care system and it is highly plausible that some patients may not receive immediate prophylaxis or treatment when symptoms are just beginning to manifest. With large numbers of patients presenting to emergency departments seeking care, it is crucial that emergency physicians, intensivists and other clinicians understand the importance of therapeutic options and timing available to them. For patients with inhalational anthrax who progress to severe disease, morbidity and mortality are largely due to the detrimental effects of toxemia, so the timing for effective treatment of toxin-mediated disease must be understood in order to effectively plan for and respond to such a public health emergency. The United States Strategic ...

Researchers at the US Department of Energys Brookhaven National Laboratory have developed a device, dubbed ThraxVac, that can collect and kill anthrax and other bacterial spores. The patent-pending device has been licensed to Circle Group Holdings, Inc, a public company based in Mundeen, Illinois.. ThraxVac vacuums up anthrax and other bacterial spores, then tricks the spores into germinating through heat and moisture, making them vulnerable to injury. The newly activated spores are then bombarded with alpha particles, which kill the spores, rendering them non-toxic.. Carl Czajkowski, a Brookhaven Lab scientist, and Barbara Panessa-Warren, a biology consultant for Brookhaven, thought of the idea for the invention together in 2001 shortly after several anthrax incidents in the US were widely reported.. We thought there must be a better way to clean up anthrax, other than using harsh chemicals that are dangerous to humans and to the environment. Also, chemicals often cant do the job ...

The findings came after Stanford University research into anthrax found susceptibility to the acute disease caused by the bacterium Bacillus anthracis varied from person to person.

With my admittedly limited resources (time/access to journals), I tried to do as extensive a search on safety studies of the anthrax vaccine as possible. Report after report stated that the most common reactions to the vaccine tended to be local and of mild to moderate severity, being limited mainly to erythema, edema and pruritis. Severe reactions of these types were rare, and none of the studies found any connection between the vaccine and long-term health issues, like autoimmune disorders or chronic fatigue. My best guess is that chronic issues are most likely unrelated to the vaccine and may be due to other factors (e.g., other environmental causes, stress and/or psychogenic illness, etc.). If they are connected to the vaccine, they seem to be so exceedingly rare that, for individuals at risk of anthrax exposure, the benefits of the vaccine outweigh the remote risks of a serious AE. Of course, research on the anthrax vaccine should continue. For one thing, we should have more than one ...

Anthrax is a zoonotic disease, occurring in wild and domestic mammals, caused by the spore-forming bacterium Bacillus anthracis (B. anthracis). Anthrax occurs in humans when they are exposed to infected animals, tissue from infected animals or when they are directly exposed to B. anthracis or its spores. Depending on the route of infection, anthrax disease can occur in three forms: cutaneous, gastrointestinal, and inhalation. In the United States of America (USA), the annual incidence of human anthrax has declined from approximately 130 cases annually in the early 1900s to no cases during 1999 to 2000. However, in the USA, shortly after September 11th, 2001, there were 22 cases (18 confirmed) of inhaled and cutaneous anthrax infection that were related to contaminated mail. The development of a new anthrax vaccine is necessary because the current AVA vaccine requires the growth of B. anthracis in its manufacturing process and has a complex administration regimen of six administrators of vaccine ...

The only known effective pre-exposure prevention against anthrax is the anthrax vaccine. The vaccine was developed from an attenuated strain of B. anthracis. The vaccine derives from the cell-free culture filtrate of this strain and, in its final formulation, is adsorbed onto an aluminum salt. A well controlled clinical trial using an anthrax vaccine similar to the licensed anthrax vaccine was conducted in U.S. mill workers processing imported animal hair. During the trial, 26 cases of anthrax were reported at the mills - five inhalation and 21 cutaneous cases. Of the five inhalation cases, two individuals had received the placebo, while three individuals were in the observational group. Four of the five people who developed inhalation anthrax died. No cases of inhalation anthrax occurred in anthrax vaccine recipients. Based upon a comparison between the anthrax vaccine and placebo recipients, the authors calculated a vaccine efficacy level of 92.5 percent ...

Jupiter Images / iStockphoto. The bacterium Bacillus anthracis occurs worldwide, its natural habitat is the soil. The pathogen causes the often fatal ending anthrax (Anthrax) in humans and in herbivorous animals such as cows or sheep. 95 percent by a Bacillus anthracis infection lead to all cutaneous anthrax, initially manifested by a painless, itchy papules on the hands, forearms or face, the black turns later from the center. but the bacterium can other forms of anthrax as Inhalation anthrax or Gastrointestinal anthrax trigger. All three forms can include one anthrax sepsis entail that ends in a few hours fatal. The bacteria form resistant survival structures (spores), which can remain viable for decades in nature. In the body, Bacillus anthracis is a special capsule of D-glutamic acid, which protects the pathogen from the scavenger cells of the immune system.. Especially in southern Europe and South America there are often anthrax disease caused by Bacillus anthracis in farm animals. The ...

In September 2011, a total of 511 human cases of anthrax (Bacillus anthracis) infection and 5 deaths were reported in a game management area in the district of Chama, Zambia, near where 85 hippopotamuses (Hippopotamus amphibious) had recently died of suspected anthrax. The human infections generally responded to antibiotics. To clarify transmission, we conducted a cross-sectional, interviewer-administered household survey in villages where human anthrax cases and hippopotamus deaths were reported. Among 284 respondents, 84% ate hippopotamus meat before the outbreak. Eating, carrying, and preparing meat were associated with anthrax infection. Despite the risk, 23% of respondents reported they would eat meat from hippopotamuses found dead again because of food shortage (73%), lack of meat (12%), hunger (7%), and protein shortage (5%). Chronic food insecurity can lead to consumption of unsafe foods, leaving communities susceptible to zoonotic infection. Interagency cooperation is necessary to prevent

Anthrax, the zoonotic disease caused by the gram-positive bacterium Bacillus anthracis, is nowadays rare in northern parts of Europe including Finland and Scandinavia. Only two minor outbreaks of anthrax in 1988 and in 2004 and one sporadic infection in 2008 have been detected in animals in Finland since the 1970s. Here, we report on two Finnish B. anthracis strains that were isolated from spleen and liver of a diseased calf related to the outbreak in 1988 (strain HKI4363/88) and from a local scrotum and testicle infection of a bull in 2008 (strain BA2968). These infections occurred in two rural Finnish regions, i.e., Ostrobothnia in western Finland and Päijänne Tavastia in southern Finland, respectively. The isolates were genetically characterized by PCR-based methods such as multilocus variable number of tandem repeat analysis (MLVA) and whole genome-sequence analysis (WGS). Phylogenetic comparison of the two strains HKI4363/88 and BA2968 by chromosomal single nucleotide polymorphism (SNP) analysis

The pathogen Bacillus anthracis secretes two potent toxins during anthrax infection, known as lethal factor (LF) and oedema factor (EF). Using transgenic Drosophila as a model system for the identification of pathways that might be involved in anthrax pathogenesis, Ethan Bier and colleagues show that these two toxins interact synergistically to block Rab11/Sec15 exocyst-dependent endocytic recycling, resulting in reduced Notch signalling and cadherin-dependent adhesion at the adherens junction. Tests in human endothelial cells indicate that the toxins have a similar effect on Rab11/Sec15 activity and Notch signalling. During infection, Bacillus anthracis secretes two potent toxins called lethal factor and oedema factor. Using Drosophila melanogaster as a model system, these authors show that these toxins interact with the Rab11/Sec15 exocyst, which is involved in endocytic recycling. This interaction may explain vascular leakage during infection. Bacillus anthracis is the causative agent of anthrax in

But as recently as this spring, the Government Accountability Office, the investigative arm of Congress, said questions remain about the vaccine. The long term safety of the licensed vaccine has not been studied, the agency said in a May 9 report. . . . Also, there is some evidence that the current anthrax vaccine may have diminished efficacy against certain virulent strains of anthrax. Barbara Loe Fisher, president of the National Vaccine Information Center, said her nonprofit advocacy group is adding more information to its Web site about the research and development of biological defense vaccines. The DOD has a moral duty to fully disclose anthrax vaccine risks, as well as benefits, to soldiers and allow them to make an informed, voluntary decision, she said in a statement - Christopher Lee, Washington Post, October 17, 2006 Mandatory Anthrax Shots to Return ...

PURPOSE: In the 1960s, the Centers for Disease Control and Prevention (CDC) held the investigational new drug (IND) application for the anthrax vaccine and collected short-term safety data from approximately 16,000 doses administered to almost 7000 individuals. While some recent anthrax vaccine safety studies have suggested that women experience more injection site reactions (ISRs), to our knowledge the IND safety data were not previously examined for a gender-specific difference. METHODS: We identified and analyzed a subset of the IND study data representing a total of 1749 persons who received 3592 doses from 1967 to 1972. Original data collection forms were located and information extracted, including: vaccine recipients name, age at vaccination, gender, dose number, date of vaccination, lot number, grading of ISR, presence and type of systemic reactions. Overall and gender-specific rates for adverse reactions to anthrax vaccine were calculated and we performed a multivariable analysis. ...

Anthrax was first tested as a biological warfare agent by Unit 731 of the Japanese Kwantung Army in Manchuria during the 1930s; some of this testing involved intentional infection of prisoners of war, thousands of whom died. Anthrax, designated at the time as Agent N, was also investigated by the allies in the 1940s. The British army tested experimental anthrax weapons on Gruinard Island, off the northwest coast of Scotland, in 1943. Gruinard was burned over at least once, yet as of the late 1980s, it was still too heavily contaminated with spores to allow unprotected human access, indicating the hardiness of anthrax spores. Weaponized anthrax was part of the U.S. stockpile prior to its destruction in 1972.. ...

In 1855, Aloys Pollender - a German Physician - published his findings on anthrax in which he described a group of stick-shaped bacteria that were present in the blood of infected animals. He is credited with recognizing the pathogen Bacillus anthracis. In 1864, Casimir Davaine - a French physician - studied the bacteria found in the blood of people infected with anthrax, and found that they physically resembled the bacteria described by Dr. Pellender, and thus concluded that the symptoms of anthrax occurred when these bacteria were present in the blood. Later in 1876, Robert Koch provided conclusive evidence that Bacillus anthracis was the cause of anthrax (Théodoridès 159 ...

Use of the Anthrax Vaccine Absorbed (AVA) expanded in 1991, when the U.S. military, concerned that Iraq possessed anthrax bioweapons, administered the vaccine. As more service members were vaccinated, however, some of them raised concerns about the safety and efficacy of AVA, and some also suggested a possible link between AVA vaccination and the illnesses experienced by some veterans. In October 2000, the IOM convened the Committee to Assess the Safety and Efficacy of the Anthrax Vaccine to evaluate these difficult issues.

Dr. Kwai Chan testified on 29 April 1999, Mr. Chairman and Members of the Subcommittee:. We are pleased to be here today to discuss the results of our ongoing examination of the safety and efficacy of the anthrax vaccine, which is being done at your request. My testimony presents preliminary findings on (1) the short- and long-term safety of the vaccine, (2) the efficacy of the vaccine, and (3) problems the Food and Drug Administration (FDA) found in the vaccine production facility in Michigan that could compromise the safety, efficacy, and quality of the vaccine. We plan to issue the final report on our review this fall.. As you know, concerns have been raised about the Department of Defense s (DOD) anthrax immunization program since the Department began vaccinating the first of 2.4 million active duty and reserve members. For example, some Gulf War veterans are suffering from unexplained illnesses that they believe might have been caused by anthrax vaccines that they received during the war. ...

Anthrax toxin. Anthrax is primarily a disease of herbivores caused by gram-positive, aerobic, spore-forming Bacillus anthracis. Humans are accidental hosts through the food of animal origin and animal products. Anthrax is prevelant in most parts of the globe, and cases of anthrax have been reported from almost every country. Three forms of the disease have been recognized: cutaneous (through skin), gastrointestinal (through alimentary tract), and pulmonary (by inhalation of spores). The major virulence factors of Bacillus anthracis are a poly-D glutamic acid capsule and a three-component protein exotoxin. The genes coding for the toxin and the enzymes responsible for capsule production are carried on plasmid pXO1 and pXO2, respectively. The three proteins of the exotoxin are protective antigen (PA, 83 kDa), lethal factor (LF, 90 kDa), and edema factor (EF, 89 kDa). The toxins follow the A-B model with PA being the B moeity and LF/EF, the alternative A moeities. LF and EF are individually ...

Whilst various remedial human monoclonal antibodies have been developed to treat the potentially life-threatening systemic complications associated with anthrax infection, an optimal and universally effective administration route has yet to be established. In the later stages of infection when antibody administration by injection is more likely to fail one possible route to improve outcome is via the use of an antibody-bound, adsorbent haemoperfusion device. We report here the development of an adsorbent macroporous polymer column containing immobilised B. anthracis exotoxin-specific antibodies, PANG (a non-glycosylated, version of a plant-produced human monoclonal antibody) and Valortim (a fully human monoclonal N-linked glycosylated antibody), for removal of anthrax protective antigen (PA) from freshly frozen human plasma and human whole blood. In addition, we have demonstrated that continuous extracorporeal blood recirculation through a Valortim-bound haemoperfusion column significantly ...

Host genetic variation, particularly within the human leukocyte antigen (HLA) loci, reportedly mediates heterogeneity in immune response to certain vaccines; however, no large study of genetic determinants of anthrax vaccine response has been described. We searched for associations between the immunoglobulin G antibody to protective antigen (AbPA) response to Anthrax Vaccine Adsorbed (AVA) in humans, and polymorphisms at HLA class I (HLA-A,-B, and-C) and class II (HLA-DRB1,-DQA1,-DQB1,-DPB1) loci. The study included 794 European-Americans and 200 African-Americans participating in a 43-month, double-blind and placebo-controlled clinical trial of AVA (clinicaltrials.gov identifier NCT00119067). Among European-Americans, genes from tightly linked HLA-DRB1,-DQA1,-DQB1 haplotypes displayed significant overall associations with longitudinal variation in AbPA levels at 4, 8, 26 and 30 weeks from baseline in response to vaccination with three or four doses of AVA (global P6.53 × 10 4). In particular, ...

Lack of available iron is one of many environmental challenges that a bacterium encounters during infection and adaptation to iron starvation is important for the pathogen to efficiently replicate within the host. Here we define the transcriptional response of B. anthracis Sterne (34F2) to iron depleted conditions. Genome-wide transcript analysis showed that B. anthracis undergoes considerable changes in gene expression during growth in iron-depleted media, including the regulation of known and candidate virulence factors. Two genes encoding putative internalin proteins were chosen for further study. Deletion of either gene (GBAA0552 or GBAA1340) resulted in attenuation in a murine model of infection. This attenuation was amplified in a double mutant strain. These data define the transcriptional changes induced during growth in low iron conditions and illustrate the potential of this dataset in the identification of putative virulence determinants for future study.

We recently found that a small population of these macrophages is spontaneously and temporally refractory to LeTx-induced cytotoxicity. Analysis of genome-wide transcripts of a resistant clone before and after regaining LeTx sensitivity revealed that a reduction of two closely related mitochondrial proteins, Bcl-2/adenovirus E1B 19-kDa interacting protein 3 (Bnip3) and Bnip3-like (Bnip3L), correlates with LeTx resistance. Down-regulation of Bnip3 and Bnip3L was also found in toxin-induced resistance whereby sublethal doses of LeTx induce resistance to subsequent exposure to cytolytic toxin doses. The role of Bnip3 and Bnip3L in LeTx-induced ...

AHRP) Whose children will be sacrificed in an illegal and unethical experiment in the name of Biodefense Preparedness? According to BioPrepWatch.com , the Obama administration is seeking to obtain a green light to conduct an anthrax vaccine safety experiment on US children. The stated rationale for such a trial, articulated by Dr. Nicole Lurie, US Dept. of Health and Human Services, is that there are no data about the safety of exposing children to the anthrax vaccine. And if an emergency arises, a trial would present an array of logistical, clinical and communication challenges during a public health crisis.. No child would benefit from exposure to a vaccine that has generated thousands of adverse event reports-including deaths-in adults..

The book describes weeks of anxious discussions about the possibility that Iraq would unleash its presumably limited inventory of anthrax spores and botulinum toxin against coalition forces. U.S. military planners guessed that the Iraqis would target frontline troops with botulinum and would direct anthrax against the rear. The logic arose from the fact that the toxin disables its victims in minutes or hours, whereas the incubation period for anthrax is a day or more. The planners figured that by the time untreated rear-guard troops were moved forward, anthrax infections would have incapacitated them. These presumptions appeared critical in the face of inadequate vaccine supplies. To the chagrin of the commanders, although a half-million American troops would be sent to the Gulf area, there was enough anthrax vaccine only for 150,000 and botulinum vaccine for 10,000. Layered onto the scarcity problem were uncertainties about the safety and effectiveness of the anthrax vaccine. The uncertainties ...

0109]An example of a positive control is one that contains an amount of lymphocyte-associated LT activity present (such as the functional activity, for example an amount of cell proliferation or amount of secreted MAPKK-dependent cytokine) when cells are infected with LT and contacted with an agent known to decrease anthrax pathogenicity (such as a neutralizing antibody to anthrax LT). For example, the control can include an amount of cell proliferation or an amount of MAPKK-dependent cytokine (such as an amount of IL-2, IL-4, IL-6, or IFN-γ). When comparing the lymphocyte-associated LT activity present in the experimental to the positive control, similar or even reduced lymphocyte-associated LT activity relative to the positive control indicates the test agent decreases pathogenicity of anthrax. For example, when comparing the lymphocyte-associated LT activity present in the experimental to the positive control, similar or increased cell proliferation or MAPKK-dependent cytokine activity (such ...

Excellent results in the treatment of infected livestock by penicillin therapy have been reported from different parts of the United States and France. In cattle, intramuscular administration of 1 to 3 million units or more of penicillin during the early stages of the disease resulted in marked improvement in 36 hours or less, with complete recovery in 1 to 5 days. Large doses of penicillin (9 to 12 million units) in combination with injections of anthrax antiserum have given good results in the treatment of animals affected with postvaccination anthrax. Postvaccination anthrax in cattle and horses showing advanced symptoms has been successfully treated with a combination of penicillin intramuscular and oxytetracycline intravenously, or oxytetracycline alone intravenously. The administration of anthrax antiserum or penicillin, singly or in combination, to infected swine also hastens recovery. In the past, veterinary officials in some States recommended prophylactic treatment of exposed cattle in ...

Research published by Army scientists indicates that a minor reduction in levels of one particular gene, known as CD45, can provide protection against two divergent microbes: the virus that causes Ebola hemorrhagic fever and the bacterium that causes anthrax. Taken together, the results suggest a common host restriction factor and a promising approach to drug development for treating two completely different infections.

We evaluated the abilities of pulsed-field gel electrophoresis (PFGE) and sequences of intergenic spacer regions (ISRs) between two highly conserved genes, 16S-23S rDNA and gyrB-gyrA ISRs, to detect variation in strains of Bacillus anthracis as well as two closely related species, B. cereus ATCC 14579 and B. mycoides ATCC 6462. For each restriction enzyme, (NotI, SfiI, and SmaI), the PFGE banding patterns for three B. anthracis strains (Ames, Vollum, and Sterne) were identical. However, closely related species could be differentiated from B. anthracis and from each other. PCR amplification of the 16S-23S rDNA ISR yielded a 143- to 144-bp fragment, showing identical sequences for B. anthracis strains, one nucleotide deletion between B. cerus and B. anthracis, and 13 nucleotide differences between B. mycoides and B. anthracis. The gyrase ISR sequences (121 bp) in B. anthracis strains were also identical, but those in B. cereus and B. mycoides differed from that in B. anthracis by 1 and 2 ...
