Question

Which of the following is/are bacterial disease?
(A) Whooping cough
(B) Cholera
(C) Tuberculosis
(D) All of the above

Answer 1

These diseases occur due to eating contaminated food or drinking contaminated water, inhaling contaminated air-borne droplets into the lungs and nose.

Complete answer: Bacterial diseases are caused by pathogenic bacteria. Bacterial diseases take place when pathogenic bacteria get into the body through contaminated food, water or air.
When bacteria enter the body, a healthy immune system may identify the bacteria as foreign invaders and attempt to destroy or avoid the replication of the bacteria. However, the body isn't always able to stop the bacteria from growing and spreading even in a healthy person. They will crowd out healthy bacteria and microorganisms as the harmful bacteria multiply and release toxins that kill the body's cells.

Now lets us find the solution from the given options-
1. Whooping cough is the bacterial disease which is caused by bacterium Bordetella pertussis. It is a contagious respiratory disease.
2. Cholera is the bacterial disease that is caused by the bacterium Vibrio cholerae. It spread through contaminated water. It causes diarrhea and dehydration.
3. Tuberculosis is the bacterial disease that is caused by the bacterium Mycobacterium tuberculosis. It is a potentially severe infectious disease that affects primarily the lungs.

Thus, the right answer is option D i.e., All of the above

Note: Bacterial diseases are the direct transmission diseases because here the pathogens are directly carried to the human body without intermediate agents. This can occur either by contacting an infected person, from the bite of an animal such as rabies, or through placenta from mother to foetus.
