What are antibiotics?

Antibiotics are medicines that fight infections caused by bacteria in humans and animals either by killing the bacteria or by making it difficult for them to grow and multiply.

History

In 1928, the British doctor and scientist Alexander Fleming found that the substance produced by certain fungi, scientifically named Penicilliumnotatum, had the effect of destroying microbial cultures. This is how penicillin arose: the first antibiotic obtained from a natural source.

Overuse of antibiotics

Antibiotics are one of the great advances in medicine. But, the abuse of antibiotics has led to the development of resistant bacteria (which are more difficult to treat). Some germs that once responded well to antibiotics have become more and more resistant to this type of medication.

What is a descriptive adjective?

duranxavy — 2023-09-25 22:06:16 UTC

A descriptive adjective is an adjective that modifies a noun or pronoun by describing it or expressing its quality.

Example

I don’t like cold weather. (The adjective cold modifies the noun weather. Cold is a descriptive adjective that qualifies the weather by saying it has a low temperature.)
