Anthrax is a highly contagious and infectious soil-borne disease caused by Bacillus anthracis, a relatively large spore-forming bacteria that can infect mammals. Anthrax is primarily a disease of herbivores, particularly bison and beef cattle. Anthrax infections are rare in humans. Beef cattle and bison are most likely to contract the disease because they graze lower to the ground than many other herbivores, often due to drought or management practices. It is also believed that the abrasive forages they consume can injure the mouth and allow the bacteria quick access to the bloodstream.

These buffaloes are used for heavy draught purpose and farmers prefer this breed due to its low maintenance cost, efficiency of feed conversion, moderate production and better adaptation to local climatic conditions. Therefore it serves dual purpose of milkers and draught cattle.

Are healthier due to a good diet
-
Catch infections easily
-
May suffer vitamin K deficiency and prolonged bleeding

Vitamin K is essential for liver function, necessary to prevent the seepage of blood from the circulatory system and to establish blood clotting. Without vitamin K, the blood will not clot properly after an injury, and this is why sweet clover poisoning is also called sweet clover bleeding disease.

Who is the pioneer of 'White revolution' in India?
-
Swaminathan
-
Verghese Kurien

Dhiru Bhai Ambani
-
S.K. Birla
Verghese Kurien known as the 'Father of the White Revolution' in India,[2] was a social entrepreneur whose "billion-litre idea", Operation Flood, the world's largest agricultural dairy development programme, made dairy farming India's largest self-sustaining industry and the largest rural employment provider, being a third of all rural income, with benefits of raising incomes and credit, riddance of debt dependence, nutrition, education, health, gender parity and empowerment, breakdown of caste barriers and grassroots democracy and leadership. It made India the world's largest milk producer from a milk-deficient nation, which doubled milk available per person and increased milk output four-fold, in 30 years. A key invention at Amul, the world's first, was the production of milk powder from the abundant buffalo-milk, instead of from the conventional cow-milk, short in supply in India. Keen on a strong linkage between town and country, he surmounted skepticism and adversity with his indefatigable fighting spirit and outmaneuvering skills to capture a commanding share of the market of the city of Bombay (now, Mumbai), which got him wide attention.
Mark the incorrect statement:

b) It destroys some organisms
c) Makes the milk tasty

a, b
-
b, c
-
a, c
-
All
Pasteurized milk can be consumed without boiling as it is free from harmful microbes. The milk is heated to about $700^{\circ}C$ for $15$ to $30$ seconds and then suddenly chilled and stored. By doing so, it prevents the growth of microbes. This process was discovered by Louis Pasteur. It is called pasteurization.

Alexander Fleming
Waksman is credited with coining the term antibiotics, to describe compounds derived from other living organisms such as penicillin, though the term was first used by the French dermatologist François Henri Hallopeau, in 1871, to describe a substance opposed to the development of life
Pasteur effect is due to
-
Change from aerobic to anaerobic
-
Providing oxygen to anaerobically respiring structures
-
Rapid utilisation of ATP
-
Nonsynthesis of ATP
Most microorganisms such as fungi and bacteria can grow and flourish in the complete absence of oxygen and is known as fermentation. Pasteur described that fermentation is directly associated with the growth of metabolism of living matter. He observed that the rate of fermentation was considerably higher under anaerobic conditions as compared to aerobic conditions. The inhibition of anaerobic breakdown of sugars into carbon dioxide and ethyl alcohol due to the presence of oxygen under aerobic conditions is known as Pasteur effect.
The method of growing micro-organisms as a thin layer on a nutrient medium is known as
-
Thin layer growth system
-
Support growth system
-
Suspended growth
-
None of these
Support growth system refers to a process in which the microorganisms are grown on a thin layer of nutrient medium. A nutrient medium provides various nutrients required for the growth of microorganism to carry out their metabolic activities. The nutrient media supports the growth of a wide range of microorganisms. So, the correct answer is 'Support growth system'.
Exceptions to Koch's postulates are
-
Viruses
-
Fungi
-
Protozoans
-
Spirochaetes
Koch's postulate designed the causative relationship between a microbe and a disease. Viruses are obligate intracellular parasites so they cannot be grown on artificial media.
The first person to propose that disease is due to a natural cause was
-
Aristotle
-
Hippocrates
-
Vesalius
-
Pasteur
Hippocrates believed that disease caused inside the body is due to a natural cause not by gods and superstition. He gave humor theory based on the black bile produced, which was later rejected.
Who saved the silk industry of Germany?
-
Pasteur
-
Spallanzani
-
Robert Koch
-
Leeuwenhoek
Koch's postulates are about
-
Nutrition related diseases
-
Pathogen related diseases
-
Genetic disorders
-
Degeneration diseases
Koch's postulates are used to trace back the causal organism of a particular disease in the host organism. It designed the causative relationship between a microbe and a disease.
The process of pasteurization was invented in
-
1864
-
1964
-
1867
-
1854
Micro-organisms having optimum temperature for growth below $15^0$ C which cannot grow above $20^0$ C are called
-
Mesophiles
-
Thermophiles
-
Psychrophiles
-
None of the above
(A)Mesophile is an organism that grows in a moderate temperature from 20-45 degree Celcius.
With which of the following is the name of Louis Pasteur associated?
-
Explanation of the formation of simple organic molecules in the early atmosphere of earth
-
The proposition of the composition of gases in the early atmosphere of earth
-
Disproving the theory of spontaneous generation of organisms
-
Proposition that the first photosynthetic organisms were cyanobacteria
Distribution of clean and quality milk throughout the world has been made possible through work of
-
Leeuwenhoek
-
Koch
-
Pasteur
-

Which of the following statements holds good with pasteurization?
-
Pasteurization removes all the bacteria from milk.
-
Pasteurization is a synonym for sterilization.
-
Milk needs to be refrigerated even after pasteurization.
-
Pasteurized milk causes lactose intolerance.
a) Pasteurization does not remove all bacteria from milk. It reduces the harmful active bacteria from the milk but it is unable to kill their spores which might erupt again under favourable conditions.
The technique of developing pure culture of bacteria was developed by
-
J. Lister
-
L. Pasteur
-
R. Koch
-
A. V. Leeuwenhoek
A pure culture is a laboratory culture containing a single species of microorganisms. A pure culture was usually derived from a mixed culture (culture containing many species of organisms) by transferring a small sample into a new, sterile growth medium. Robert Koch developed solid culture media and the methods for obtaining pure cultures of bacteria.
Which famous biologist propounded the 'germ theory of disease'?
-
Joseph Lister
-
Thomas Syndenham
-
Robert Koch
-
Louis Pasteur
The more formal experiments on the relationship between germ and disease were conducted by Louis Pasteur between the year 1860 and 1864. He discovered the pathology of the puerperal fever and the pyrogenic vibrio in the blood, and suggested using boric acid to kill these microorganisms before and after confinement.
Which of the following processes are used for increasing the shelf life of milk?
-
Boiling
-
Refrigerating
-
Pasteurizing
-
All of the above
- Boiling increases the temperature of milk and kills many bacteria and thus increases the shelf life of milk when compared to raw milk.
- Refrigeration lowers the temperatures of the growth medium ( milk) making it not suitable for bacterial growth and keeps milk fresh for a particular period of time.
- Pasteurization is heating milk to high temperatures and cooling down quickly. This process kills many possible pathogens and increases the shelf life of milk to a better extent. (1 day to 2 days)
- So the correct answer is 'Boiling, Refrigerating, and Pasteurizing'.
