Question

Which one of the following is not a bacterial disease?
A. Cholera
B. Tuberculosis
C. Anthrax
D. Influenza

Answer 1

Hint: A bacterial infection is referred to as proliferation of a harmful strain of bacteria inside or on the body. Bacteria can infect any portion of the body. Pneumonia, meningitis, and food poisoning are just a few infections/illnesses that may be caused by harmful bacteria.

Complete answer:
You should know, Bacteria are single-cell organisms and are microscopic which live almost everywhere because they live in every climate and every location on earth. Some of them are airborne while others mostly live in water or soil. They live on or inside plants, animals, and people. The term "bacteria" has a negative connotation, but they actually perform many vital functions for organisms and the environment. Take an example of plants that require bacteria in the soil in order to grow.
Remember, the majority of bacteria are believed harmless to people and some strains are even beneficial. In the human gastrointestinal tract (GIT), good bacteria promote digestion and secrete many vitamins. These bacteria also aid in immunity, making the body less hospitable towards bad bacteria and other harmful pathogens that cause infections. When we consider all the strains of bacteria that exist, relatively only few mostly make people sick.
Vibrio cholerae is a bacterium that is a Causative agent of cholera.
Whereas, Tuberculosis disease is caused by bacterium- Mycobacterium tuberculosis.
Causative agent for Anthrax is - bacteria Bacillus anthracis.
influenza virus cause – Influenza, that means it is a viral disease

Therefore, our correct answer is option D – influenza.

Additional information:
Keep in head, that Bacteria come basically in three shapes namely, -rod-shaped (bacilli), spherical (cocci), or helical (spirilla). It's important to know, Bacteria and viruses are different pathogens or organisms that can cause disease. Bacteria are larger than viruses, and bacteria are capable of reproducing on their own. Viruses are very small than bacteria and they don’t reproduce on their own.

Note: Remember, Bacteria may also be differentiated as gram-positive or gram-negative. Gram-positive bacteria consist of a thick cell wall, whereas the gram-negative bacteria do not have. Gram staining, bacterial culture along with antibiotic sensitivity determination, and other tests as genetic analysis are used to identify bacterial strains and help in determining the appropriate course of treatment.
