How Stuff Works

How Antibiotics Work

Antibiotics mean ‘against life’. These are chemical substances produced by some bacteria to stop the growth of other bacteria in their surroundings. Antibiotics differ from antiviral drugs.

How Convalescent Plasma Therapy Works

Convalescent plasma therapy involves transfusing certain components from the blood of people who have had the virus and recovered, into people who are very sick with the virus, or people who are at high risk of getting the virus.

What Is Test Pooling

Test pooling is nothing but combining 2 or more samples, to be tested at once. This reduces the cost required for testing each sample and also of the required number of test kits to test a segment of the population.

Difference Between Sterilization And Disinfectant

Both sterilization and disinfection eliminate, remove, kill, or deactivate microorganisms like viruses, bacteria, fungi, etc. But bacteria have this innate ability to form spores when the environment becomes unsuitable for their survival.

How PCR Test Works

The PCR test is a method to find a particular segment of a gene and helps in identifying disease causing micro-organism. The samples for this test can be taken from the affected area.

How Do Vaccines Work

A vaccine works by training the immune system to recognize and fight the pathogens (viruses or bacteria) in case if an infection occurs later on. 

Can Flu and Pneumonia vaccines protect against SARS-CoV2

While both Flu and Pneumonia are respiratory tract infections, they differ from SARS (Severe Acute Respiratory Syndrome) with respect to their causative agents. SARS is caused by a family of viruses known as Coronaviridae (Coronaviruses).

How Antibodies Work

Our immune system has B-Cells that are responsible for the production of specific class of proteins called antibodies. They bind to the antigens and helps our immune system to fight off the invaders.

How Vaccines Are Made

Pathogens are disease-causing agents that reproduce inside our bodies, produce toxins, and disturb our normal human physiology. Vaccines can be produced in different ways.
