Question

Which microorganism is responsible for cholera, typhoid and dysentery?
A. Bacteria
B. Virus
C. Fungi
D. Protozoa

Answer 1

Hint: The bacterium ‘Vibrio cholerae' causes cholera, which is a bacterial disease. This bacteria is commonly found in contaminated foods. It's also found where there aren't enough sanitation facilities.
Typhoid is a bacterial infection that is spread primarily through contaminated food or water. It can also spread as a result of a lack of hygienic conditions. High fever, loss of appetite, and diarrhea are the most common symptoms of this illness.
Dysentery is a gastrointestinal infection that results in bloody diarrhea. A parasite or bacteria can cause it.

Complete answer:
Option A: Cholera is a severe diarrheal illness caused by the Vibrio cholerae bacteria infecting the bowel. Typhoid fever is a potentially fatal infection caused by the Salmonella typhi bacteria. Entamoeba histolytica is the parasite that causes amoebic dysentery.
So, option A is correct.
Option B: cholera, typhoid and dysentery are caused by bacteria.
So, option B is not correct.
Option C: The Vibrio cholerae bacteria invading the gut causes cholera, a severe diarrheal sickness. The Salmonella typhi bacteria causes typhoid fever, a potentially lethal infection. Entamoeba histolytica is the parasite that causes amoebic dysentery.
So, option C is not correct.
Option D: Salmonella typhi causes TF, whereas Vibrio cholerae causes cholera by infecting the intestine with the toxin-producing bacterium Vibrio cholerae.
So, option D is not correct.

Therefore, Option A is the correct answer.

Note:
Bacterial diseases are illnesses that are brought on by bacteria. The human body is home to a variety of bacteria. Some of these are characterised as "healthy bacteria" since they do not cause infections. Bacteria that cause sickness in humans are referred to as "harmful bacteria".
Causes -
Having sexual contact with someone who is diseased.
Sharing infected needles or tattoo needles is not a good idea.
By ingesting infectious faeces or bodily fluids.
