The first recorded use of the word "anthrax" in English is in a 1398 translation of Bartholomaeus Anglicus's work De proprietatibus rerum (On the Properties of Things, 1240). [18] Anthrax was historically known by a wide variety of names, indicating its symptoms, location, and groups considered most vulnerable to infection.
It was discovered by a German physician Robert Koch in 1876, and became the first bacterium to be experimentally shown as a pathogen. The discovery was also the first scientific evidence for the germ theory of diseases. [2] B. anthracis measures about 3 to 5 μm long and 1 to 1.2 μm wide.
His publication in 1877 on the structure of anthrax bacterium [22] marked the first photography of a bacterium. [13] He discovered the formation of spores in anthrax bacteria, which could remain dormant under specific conditions. [16] However, under optimal conditions, the spores were activated and caused disease. [16]
In September 2001, letters containing anthrax spores were mailed to several news media offices and two U.S. Senators, killing five people and infecting 17 others. Of those infected, 11 developed cutaneous anthrax, while 11 developed inhalation anthrax. 20 of the 22 infected worked at a site where contaminated mail was handled or received. [7]
Anthrax vaccines are vaccines to prevent the livestock and human disease anthrax, caused by the bacterium Bacillus anthracis. [1]They have had a prominent place in the history of medicine, from Pasteur's pioneering 19th-century work with cattle (the first effective bacterial vaccine and the second effective vaccine ever) to the controversial late 20th century use of a modern product to protect ...
In a separate announcement, the Wyoming Livestock Board said that these cases of anthrax — which were found in beef herds near Wyoming’s Elk Mountain — are the first since the 1970s. The ...
In 1876, German biologist Robert Koch discovered that a bacterium (Bacillus anthracis) was the causative pathogen of anthrax, which became the first demonstration that a specific bacterium caused a specific disease and the first direct evidence of germ theory of diseases.
The new fossil is the first to be discovered so far north in South America, and was found after over 100 years of research at the La Venta badlands, a fossil site in Colombia, the researchers said
