Edmond Nocard

Edmond Nocard ( born January 29, 1850 in Provins, † August 2, 1903 in Saint -Maurice, Val -de- Marne département ), was a French veterinarian and pioneer of microbiology and infectious diseases. The bacterial genus Nocardia is named after him.


Edmond Nocard studied at the Veterinary School in Maisons -Alfort 1868-1871 veterinary medicine. In 1871 he was called up for military service due to the German - Prussian War, but could be studied thereafter continue and received in 1873 his diploma as a veterinary surgeon. From 1873 to 1878 he worked at the clinic of the school.

In 1878 he was appointed professor of clinical and surgical veterinary medicine in Alfort. Among his students were many prominent researchers, among them Camille Guérin and Henri Carré.

1880 moved Nocard as an assistant in the laboratory of Louis Pasteur in Paris where he. Together with Pasteur and Emile Roux worked on the development of invented by Henry Toussaint vaccine against anthrax In 1883, he went along with Roux to Egypt, where he investigated a cholera epidemic, but could not isolate the pathogen. Later that year he returned to Alfort back, where he established a microbiological research laboratory with the support of Pasteur, was later to emerge from the Laboratoire National de Recherches. In the following three years he developed several new bacteriological techniques, including new culture media for Mycobacterium tuberculosis, the causative agent of tuberculosis. In his clinical work, he led the intravenous anesthesia with chloral hydrate at a livestock and dealt with the tetanus prevention.

In 1887 he was promoted to principal of the School of Veterinary Medicine and Chairman of the range of infectious diseases.

In this time, the publication of his book La Bovine tuberculosis falls: ses Dangers, ses rapports avec la tuberculosis humaine classique.

Another contribution Nocards for veterinary medicine was the discovery of later named after him bacterial genus Nocardia, whose first known organism he described in 1888 as Streptothrix farcinica. The bacteria of this genus cause disease nocardiosis. He also discovered an important causative agent of mastitis in cows, Streptococcus agalactiae, the causative agent of pseudotuberculosis as well as the causative agent of contagious bovine pleuropneumonia the first excitation of the group of mycoplasmas.
