Question

Robert Koch's postulates to establish a micro-organism as a pathogen can be obtained, after his work on?
A) Hydrophobia
B) Anthrax
C) Smallpox
D) Diphtheria

Answer 1

Hint: Robert Koch’s full name is Heinrich Hermann Robert Koch. He was a microbiologist and German physician. He discovered causative agents of deadly infectious diseases like cholera, anthrax, and tuberculosis. And is also one of the main founders of modern bacteriology.

Complete step-by-step answer:
Anthrax was common among the farm animals in the Wollstein district and Koch. Previously anthrax bacillus was discovered by Pollender, Rayer, and Davaine, and Koch wanted to prove that this bacillus is the cause of the disease. He inoculated mice, by use of slivers of wood, and anthrax bacilli taken from spleens of healthy animals who did not suffer from the disease. This also proved and confirmed the work of others who said that the disease can be transmitted through the blood of animals that had anthrax.
Anthrax is caused by bacillus anthracis. It is marked by the appearance of skin papules on the body. It is transmitted through human infections that usually occur through a cut or abrasion of the skin. It can be cured by ciprofloxacin or doxycycline.
Therefore the correct answer is option B i.e., anthrax .

Note: Robert Koch was awarded a Nobel prize for physiology or medicine in 1905. Based on his knowledge of biology and the mode of distribution of cholera vibrio, Koch made rules for the control of epidemics which were approved by the Great Powers in Dresden in 1893.
