This study will examine pathophysiology and immune response of anthrax in infected or exposed individuals to learn more about the disease symptoms, prevention and response to treatment. In addition, it will evaluate immune response to the anthrax vaccine AVA (Anthrax Vaccine Adsorbed) in healthy, non-infected individuals. The following individuals may be eligible for this study: 1. People with confirmed or suspected anthrax (inhalational, cutaneous or gastrointestinal, either acute or recovering); 2. People exposed to anthrax who have no clinical symptoms. 3. Healthy people who have not been exposed to anthrax and have been vaccinated with AVA. Those enrolled in the study will undergo the following tests and procedures. Infected and exposed individuals: * Symptomatic participants will have the following clinical procedures if medically necessary: * a) blood tests for cell counts, chemistries and evidence of anthrax bacteria; * b) nasal swab to test for evidence of anthrax * c) chest X-ray; * d) computed tomography (CT) scan (special X-rays to examine the lungs or abdomen); * e) echocardiogram to examine the heart * f) magnetic resonance imaging (MRI), a special imaging test using a magnetic field and radio waves to examine the infected area of skin and soft tissue for patients with cutaneous anthrax. * All subjects (with or without symptoms) will have the following research procedures: * a) blood tests to examine immune response to anthrax; * b) throat swab to test for e…

* INCLUSION CRITERIA: Subjects at least 3 years old, including pregnant women, are eligible for inclusion if they meet one of the five criteria listed below, are hemodynamically and clinically stable, and agree to stored samples. Women of child-bearing age or potential will not be excluded from participation but pregnancy status will be determined by serum or urine pregnancy test at time of enrollment in order to optimize subsequent evaluation and care. Although the study is open to participants at least 3 years old, pediatric anthrax cases are historically rare and essentially of the cutaneous type. Therefore, few, if any pediatric subjects are expected. Decisionally impaired subjects will be included in this study only if a Legally Authorized Representative (LAR) understands and is willing to sign a written informed consent document. 1. Inhalation Anthrax (acute or recovering infection) CONFIRMED: --nonspecific febrile illness followed by sepsis and/or respiratory failure AND --B anthracis isolation (via culture) from any site OR 2 supportive lab tests OR SUSPECTED: --nonspecific febrile illness followed by sepsis and/or respiratory failure with no alternative diagnosis AND --one supportive lab test OR direct epidemiological link to a confirmed environmental exposure 2. Cutaneous Anthrax (acute or recovering infection) CONFIRMED: --characteristic lesion (papule-\>vesicular-\>depressed black eschar plus or minus edema, erythema, necrosis, or ulceration) AND --B anthracis isolation (culture) from any site OR 2 supportive lab tests SUSPECTED: --Characteristic lesion with no alternative diagnosis AND --one supportive lab test OR direct epidemiological link to a confirmed environmental exposure 3. Gastrointestinal Anthrax (acute or recovering infection) CONFIRMED: --Severe abdominal pain often associated with bloody vomiting/diarrhea followed by fever/septicemia AND --B anthracis isolation (culture) from any site OR 2 supportive lab tests SUSPECTED: --Severe abdominal pain often associated with bloody vomiting/diarrhea followed by fever/septicemia with no alternative diagnosis AND --1 supportive lab test OR direct epidemiological link to a confirmed environmental exposure These definitions were subsequently updated by the CDC in 2010 to accept clinically compatible symptoms plus one of the following: a positive culture, a positive immunohistochemical stain for antigen, a 4-fold increase in anti-PA IgG or a positive documented exposure with detection of DNA via PCR (26). 4. Exposed individuals who are clinically asymptomatic. 5. Past or imminent vaccination in healthy (non-anthrax exposed). 6. Hemodynamically and clinically stable at time of evaluation at NIH. * Hemodynamically: stable vital signs * Clinically: no obvious signs of disease progression (e.g. worsening pleural effusions or increasing cutaneous edema) * acute/newly recovered patients must be receiving standard antimicrobial therapy 7. Participant agrees to stored samples. EXCLUSION CRITERIA: Inability of subject or Legally Authorized Representative (LAR) to understand or subject not willing to sign a written informed consent document.
