Detailed explanation-1: -Antibiotics are medicines that fight infections caused by bacteria in humans and animals by either killing the bacteria or making it difficult for the bacteria to grow and multiply. Bacteria are germs.

Detailed explanation-2: -Antibiotics are used to treat or prevent some types of bacterial infection. They kill bacteria or prevent them from reproducing and spreading.

Detailed explanation-3: -In order to avoid this scenario, a few scientists came up with a new approach. Their solution is a so-called ‘living antibiotic’ method: a treatment containing bacteria against the bacterial infection.

Detailed explanation-4: -Broad-spectrum antibiotics (e.g., penicillins, aminoglycosides, cephalosporins, sulfonamides) work against a wide range of bacterial infections. Narrow-spectrum antibiotics (e.g., macrolides, vancomycin, fidaxomicin) are only effective against a few types of pathogenic bacteria.

Detailed explanation-5: -They kill the bacteria or stop it from spreading. This helps the body’s natural immune system to fight the infection. There are many types of antibiotics.
