Question

Diphtheria is caused by
a. Poisons released by living bacteria cells
b. Poisons released by virus
c. Poisons released by dead bacterial cells
d. Excessive immune response by host’s body

Answer 1

The infection which is caused by the Corynebacterium diphtheriae is called Diphtheria. The symptoms can vary from mild to severe. After the exposure of the infection, it usually starts within two to five days. The symptoms can be sneezing, cough, fever, or blowing their nose. The infection can spread through person-to-person contact.

Complete answer:
The poisons released by the living bacterial cells named Corynebacterium diphtheriae caused the infection of Diphtheria. The lymph nodes get swollen, nerves, and kidney inflammation takes place. There can be mild illness in some people whereas severe in others. There are some risk factors of diphtheria which are as follows:
- People who do not vaccinate themselves timely.
- People in crowded and unhygienic conditions.
- People who travel in places where diphtheria infection is already spread.
- The poison released by the virus caused any viral infection or disease.
- One of the types of toxin named endotoxin is present in the bacterial outer membrane and until the bacterium is killed or dies in the immune system, the poison is not released.
- The immune system of the host will respond excessively and react rapidly against the infection.

Hence, the correct answer is option (A).

Additional information:
There are so many complications that can occur due to diphtheria are:

Breathing problems – The toxin produced by diphtheria mainly causes the nose and throat and damages the tissues. The breathing area gets stuck and it will create problems in normal breathing.
Heart damage – The spread of diphtheria toxin takes place via the bloodstream which will directly damage the body tissues like heart muscles.
Nerve damage – The main targets of diphtheria are nerves that cause the throat directly. This will swallow the nerves very badly.

Note: Diphtheria is a living bacterial cell infection which can infect the breathing area of the body. It can be caused by contaminated objects. People should vaccinate themselves on time against the diphtheria disorder so that if they come in exposure the infection will not occur in them. The complications can be mild which can be a cure but they may become very severe which can also cause death.
