[Anthrax: a malady of animals and of man which hides in the earth].

Anthrax is an infectious disease of herbivores, especially sheep and cattle, but also of horses, of pigs, of dogs, of wild animals and of humans. Bacillus anthracis causes the disease. This bacterium needs plenty of oxygen to procreate and to produce resistant spores, which remains viable in the soil during 3.5 years, at times during 15-20 years. The author tries to follow step by step the evolution of the ideas concerning the origin and the pathology as well as of the veterinarians measures against this disease during the 19th and 20th centuries. Many studies of the endemic anthrax were made from the beginning of the second half of the 19th century. Thanks to Louis Pasteur (1822-1895) in France and Robert Koch (1843-1910) in Germany, the anthrax could be identified with a soil-disease between 1870 and 1880. The statistics concerning the anthrax in the Grand-Duchy of Luxembourg compared to the geological and pedological structures of the soil, have fully confirmed the scientific findings at the end of the 19th century. Nowadays the anthrax has disappeared from our landscape thanks to the preventive inoculation and to the industrial use of the animal cadavers.
