Anthrax bacteria. Coloured transmission electron micrograph (TEM) of the highly pathogenic anthrax bacteria (Bacillus anthracis) and spores. Anthrax commonly infects livestock and is transmitted to humans by contact with infected animal hair,hides or excrement. There are three main forms of the disease. Cutaneous (skin) anthrax causes a raised,itchy lesion at the site of entry of the bacteria. It may be fatal if left untreated. Gastrointestinal anthrax is more serious,causing vomiting of blood and severe diarrhoea. Pulmonary (lung) anthrax,known as woolsorter's disease,is caused by inhaling the bacteria and is fatal in most cases unless treated soon after exposure | |
