  1. Lazaro Spailanzani

  2. Louis Pasteur

  3. Joseph Lister

  4. Francesco Redi

Show answer
Correct Option: B
Explanation:

Pasteur discovered that growing anthrax bacilli at about 42 °C made them unable to produce spores.  . His laboratory notebooks, now  show that he actually used heat and potassium dichromate similar to Toussaint's method, followed by inoculation of the tested animals with the weakened innoculum. The experiment, conducted  by him at Pouilly-le-Fort on sheep, goats and cows, was successful.

So, the correct answer is B. (Louis pasteur )

'Black death' is related with

animal diseases economic importance of bacteria and fungi bacteria keeping diseases away biology

  1. Plague

  2. Cancer

  3. Tuberculosis

  4. Measles

Show answer
Correct Option: A
Explanation:

The plague disease is caused by Yersinia pestis (commonly present) in populations of fleas carried by ground rodents, including marmots, in various areas including Central Asia, Kurdistan, Western Asia, Northern India and Uganda. The 'Black Death' was one of the most devastating pandemics in human history, resulting in the deaths of an estimated 75 to 200 million people and peaking in Europe in the years 134653. Although there were several competing theories as to the etiology of the Black Death, analysis of DNA from victims in northern and southern Europe published in 2010 and 2011 indicates that the pathogen responsible was the Yersinia pestis bacterium, probably causing several forms of plague.
