IMMUNOLOGY

Detailed explanation-1: -Antibiotics work by blocking vital processes in bacteria. They kill the bacteria or stop it from spreading. This helps the body’s natural immune system to fight the infection.

Detailed explanation-2: -Some, such as penicillin, kill bacteria by destroying the bacterial cell wall. Others, such as tetracycline, interfere with the ability of bacteria cells to reproduce or make proteins or nutrients they need to survive.

Detailed explanation-3: -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-4: -Each time you take an antibiotic, bacteria are killed. Sometimes, bacteria causing infections are already resistant to prescribed antibiotics. Bacteria may also become resistant during treatment of an infection.

Detailed explanation-5: -The cell wall or membranes that surrounds the bacterial cell. The machineries that make the nucleic acids DNA and RNA. The machinery that produce proteins (the ribosome and associated proteins)
