Anthrax

1). Anthrax is an acute disease caused by the bacteria Bacillus anthracis gram-positive, spore-forming bacillus.

2). Most forms of the disease are lethal, and it affects both humans and other animals.

3). Cutaneous Anthrax is known as Malignant pustule.

Clinical Features

1). Malignant pustule: a form of anthrax infection that begins as papulethat becomes a vesicle and breaks with a discharge of toxins; symptoms of septicemiaare severe with vomiting and high fever and profuse sweating; the infection is often fatal.

2). In more than 95% of cases of endemic disease, spores are transmitted from infected animals or their products by means of skin abrasions

3). A pruritic macule or papule appears at the site of inoculation.

4). The primary lesion progresses to a vesicle or a bulla after 24-48 hours.

5). The bulla enlarges to 1-2 cm, spontaneously ruptures, and forms an ulcer.

6). A hemorrhagic crust develops and is often accompanied by striking edema

Treatment

1). Anthrax cannot be spread directly from person to person, but a patient's clothing and body may be contaminated with anthrax spores.

2). Effective decontamination of people can be accomplished by a thorough wash down with antimicrobial effective soap and water.

3). Treatment for anthrax infection includes ciprofloxacin, doxycycline, erythromycin, vancomycin or penicillin.

4). In possible cases of inhalation anthrax, early antibiotic prophylaxistreatment is crucial to prevent possible death.
