    Over the past century, the development of antibiotics has saved several lives and has drastically decreased the death rate due to bacterial infections.

    Explanation:

    Antibiotics are made from bacteria and are used to kill other disease causing bacteria. The development of antibiotics was the most important achievements in 20th century. But now the problem as raised because of antibiotic resistance. Bacteria are developing resistance against antibiotic drugs such penicillin, tetracycline, etc. Due to the bacterial resistance the need to develop new antibiotics has become more important concern today. The rate at which bacteria are developing resistance is way too faster than the discovery of new antibiotic drugs.

    The discovery of antibiotics greatly improved the quality of human life in the twentieth century. Antibiotics are drugs such as penicillin (pronounced pen-ih-SILL-in) and streptomycin (pronounced strep-toe-MY-sin) used to fight infections and infectious diseases caused by bacteria. Antibiotic drugs are made from living organisms such as fungi, molds, and certain soil bacteria that are harmful to disease-causing bacteria. Antibiotics can also be produced synthetically (artificially) or combined with natural substances to form semisynthetic antibiotics. These compounds work against strains of bacteria that are resistant to other antibiotics.
