  1. Lazaro Spailanzani

  2. Louis Pasteur

  3. Joseph Lister

  4. Francesco Redi
Reveal answer Fill a bubble to check yourself
B Correct answer
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

  1. Plague

  2. Cancer

  3. Tuberculosis

  4. Measles
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

Which one of the following causes plague?

  1. Salmonella typhimurim

  2. Trichinella spiralis

  3. Yersinia pestis

  4. Leishmania donovani
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Plague is a deadly infectious disease that is caused by the enterobacteria, Yersinia pestis. Contrary to popular belief, rats did not directly start the spread of the bubonic plague. It is mainly a disease in the fleas (Xenopsylla cheopis), that infested the rats, making the rats themselves the first victims of the plague. Infection in a human occurs, when a person is bitten by a flea that has been infected by biting a rodent that itself has been infected by the bite of a flea carrying the disease. The bacteria multiply inside the flea, sticking together to form a plug that blocks its stomach and causes it to starve. The flea then bites a host and continues to feed, even though it cannot quell its hunger, and consequently the flea vomits blood tainted with the bacteria back into the bite wound.
