Penicillin was discovered by

  1. Waksman

  2. Dubois

  3. Roberk koch

  4. A. Flemming
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Waksman is known for his discovery of streptomycin, the first antibiotic effective against tuberculosis.

Robert Koch is widely known for his work with anthrax, discovering the causative agent of the fatal disease to be Bacillus anthracis. Whereas Dubois was an American sociologist who raised his voice against color discrimination.
Sir Alexander Fleming was a biologist and pharmacologist most famous for his discovery of the antibiotic substance penicillin in 1928. It was first commercial antibiotic discovered from a fungus called Penicillium notatum. 
So, the correct answer is option D.

The human body is immune to which of the following diseases?

  1. Small pox

  2. Diabetes

  3. Tuberculosis

  4. Jaundice
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Smallpox is an ancient disease caused by the variola virus. Early symptoms include high fever and fatigue. The virus then produces a characteristic rash, particularly on the face, arms and legs. The resulting spots become filled with clear fluid and later, pus, and then form a crust, which eventually dries up and falls off. Smallpox was fatal in up to 30% of cases. There is a vaccine against smallpox that was a key tool in the eradication of the disease. This vaccine does not contain the variola virus which causes smallpox, but a closely related virus called vaccinia. When this vaccine is given to humans, it protects them against smallpox. 
So the correct option is 'small pox'.

Vaccines are

  1. Same as monoclonal antibodies

  2. Treated bacteria or viruses or one of their proteins

  3. MHC proteins

  4. Strands of nucleic acids
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Some vaccines contain live, attenuated (weak or inactivated) microorganisms. Although most attenuated vaccines are viral, some are bacterial in nature. Examples include the viral diseases yellow fever, measles, rubella, and mumps, and the bacterial disease typhoid. The live Mycobacterium tuberculosis vaccine contains a virulently modified strain called BCG used to elicit an immune response to the vaccine. The live attenuated vaccine-containing strain Yersinia pestis is used for plague immunization. Rather than introducing an inactivated or attenuated micro-organism to an immune system, a fragment of it (protein subunit) can create an immune response. Examples include the subunit vaccine against hepatitis B virus that is composed of only the surface proteins of the virus, the virus-like particle (VLP) vaccine against human papillomavirus (HPV) that is composed of the viral major capsid protein. 

Therefore, the correct answer is option B.

Vaccine is a 

  1. Collection of antibiotics

  2. Collection of life saving drugs

  3. Collection of heat killed disease causing bacteria and viruses

  4. Collection of lysins
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A vaccine is a biological preparation which provides active acquired immunity to a particular disease. A vaccine contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it and keep a record of it so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

Which people are at risk of getting a particular disease ?

  1. Who never had vaccine

  2. Who didn't receive all doses of vaccine

  3. Who travel to disease prevalent areas

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Many people could still be at risk of getting a particular disease example polio. This includes those people who have never had the vaccine, those who didn't receive all doses of the vaccine, or those traveling to areas of the world where polio is still prevalent. Therefore, (d) is the correct answer.

What is the main function of vaccine ?

  1. Kill the microbes

  2. Destroy the affected organ

  3. Suppress the microbes

  4. Stimulate the body's immune system
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Vaccines stimulate the body's own immune system to protect the person against subsequent infection or disease. As vaccines contains heat killed microbes which are able to stimulate immune system. Therefore, (d) is the correct answer.

B Correct answer
Explanation

Vaccines are suspensions of killed or weakened microbes or products or derivatives of micro organisms. A vaccine produces immunity to a disease by stimulating the production of antibodies. So, it is always useful.
