Given the question: Information: - Anthrax is an infection caused by the bacterium "Bacillus anthracis". It can occur in four forms: skin, inhalation, intestinal, and injection. Symptoms begin between one day and two months after the infection is contracted. The skin form presents with a small blister with surrounding swelling that often turns into a painless ulcer with a black center. The inhalation form presents with fever, chest pain, and shortness of breath. The intestinal form presents with nausea, vomiting, diarrhea, or abdominal pain. The injection form presents with fever and an abscess at the site of drug injection. Anthrax is spread by contact with the spores of the bacteria, which are often from infectious animal products. Contact is by breathing, eating, or through an area of broken skin. It does not typically spread directly between people. Risk factors include people who work with animals or animal products, travelers, postal workers, and military personnel. Diagnosis can be confirmed based on finding antibodies or the toxin in the blood or by culture of a sample from the infected site. Anthrax vaccination is recommended for people who are at high risk. Immunizing animals against anthrax is recommended in areas where previous infections have occurred. Two months of antibiotics, such as doxycycline or ciprofloxacin, after exposure can also prevent infection. If infection occurs treatment is with antibiotics and possibly antitoxin. The type and number of antibiotics used depends on the type of infection. Antitoxin is recommended for those with widespread infection. Anthrax among humans is most common in Africa and central and Southern Asia. It also occurs fairly regularly in Southern Europe, but is uncommon in Northern Europe and North America. Globally, at least 2,000 cases occur a year, with about two cases a year in the United States. Skin infections represent more than 95% of cases. Without treatment the risk of death from skin anthrax is 24%. For intestinal infection the risk of death is 25% to 75% while in inhaled anthrax... - Anthrax is a disease with rapid onset caused by the bacterium Bacillus anthracis . Most forms of the disease are lethal , and it affects most animals . It can be transmitted through contact with infected meat . Effective vaccines against anthrax are available , and some forms of the disease respond well to antibiotic treatment . Like many other members of the genus Bacillus , B. anthracis can form dormant spores that are able to survive in harsh conditions for decades or even centuries . Such spores can be found on all continents , including Antarctica . When inhaled , eaten , or come into contact with an area of broken skin , they may become reactivated and multiply rapidly . Usually infection develops in plant eating mammals that eat or breathe in the spores while grazing . Eating is thought to be the most common route by which herbivores contract anthrax . Carnivores living in the same environment may become infected by eating infected animals . Diseased animals can spread anthrax to humans , either through direct contact or by eating raw or undercooked meat from infected animals . B. anthracis bacterial spores are soil - borne . Disturbed grave sites of infected animals have caused reinfection over 70 years after the animal 's death . Until the 20th century , anthrax infections killed hundreds of thousands of people and other animals each year . The disease is more common in countries without good public health programs and it continues to be a problem in less developed countries . French scientist Louis Pasteur developed the first effective vaccine in 1881 . Anthrax has been developed as a weapon in the past by at least five state bioweapons programs -- those of the United Kingdom , Japan , the United States , Russia , and Iraq -- and has been attempted by several others . - Bacillus anthracis is the etiologic agent of anthraxa common disease of livestock and, occasionally, of humansand the only obligate pathogen within the genus "Bacillus". "B. anthracis" is a Gram-positive, endospore-forming, rod-shaped bacterium, with a width of 1.01.2 m and a length of 35m. It can be grown in an ordinary nutrient medium under aerobic or anaerobic conditions. It is one of few bacteria known to synthesize a protein capsule (poly-D-gamma-glutamic acid). Like "Bordetella pertussis", it forms a calmodulin-dependent adenylate cyclase exotoxin known as Anthrax edema factor, along with anthrax lethal factor. It bears close genotypical and phenotypical resemblance to "Bacillus cereus" and "Bacillus thuringiensis". All three species share cellular dimensions and morphology. All form oval spores located centrally in an unswollen sporangium. "B. anthracis" endospores, in particular, are highly resilient, surviving extremes of temperature, low-nutrient environments, and harsh chemical treatment over decades or centuries. After reading the paragraphs above, we are interested in knowing the entity with which 'anthrax' exhibits the relationship of 'drug used for treatment'. Find the answer from the choices below. Choices: - ciprofloxacin - doxycycline
The answer is:
ciprofloxacin
