IMMUNOLOGY

Detailed explanation-1: -Antibiotics are critical tools for preventing and treating infections caused by specific bacteria in people, animals, and crops. In health care, antibiotics are one of our most powerful drugs for fighting life-threatening bacterial infections.

Detailed explanation-2: -A bactericidal antibiotic, such as penicillin, kills the bacteria. These drugs usually interfere with either the formation of the bacterial cell wall or its cell contents. A bacteriostatic stops bacteria from multiplying.

Detailed explanation-3: -Most of the currently available antibiotics are produced by prokaryotes mainly by bacteria from the genus Streptomyces.

Detailed explanation-4: -Antibiotics are a group of medicines that are used to treat infections caused by some germs (bacteria and certain parasites). A parasite is a type of germ that needs to live on or in another living being (host). Antibiotics do not work against infections that are caused by viruses-for example, the common cold or flu.

Detailed explanation-5: -Antibiotics are used in food animals to treat clinical disease, to prevent and control common disease events, and to enhance animal growth. The different applications of antibiotics in food animals have been described as therapeutic use, prophylactic use, and subtherapeutic use.
