Antibiotics work by targeting certain components or processes in bacterial cells. This can include disrupting the cell wall, inhibiting enzyme activity, or preventing the bacteria from replicating or synthesizing essential molecules. By targeting these specific processes, antibiotics can kill the bacteria or prevent them from spreading and causing harm.
Antibiotics are medications used to treat bacterial infections. They work by targeting and killing bacteria or inhibiting their growth. The specific mechanism of action can vary depending on the type of antibiotic, but here are some common ways in which antibiotics work:
1. Disruption of Cell Wall: Some antibiotics, such as penicillins and cephalosporins, interfere with the formation of bacterial cell walls. Bacterial cells need a strong and intact cell wall to survive, so disrupting its synthesis weakens and eventually kills the bacteria.
2. Inhibition of Protein Synthesis: Certain antibiotics, like macrolides and tetracyclines, target bacterial ribosomes, which are responsible for protein synthesis. By binding to the ribosomes, these antibiotics prevent bacteria from producing essential proteins, ultimately leading to their demise.
3. Inhibition of DNA/RNA Replication: Antibiotics like fluoroquinolones and sulfonamides hinder the replication and synthesis of bacterial DNA or RNA. By interfering with these vital processes, they impede the bacteria's ability to multiply and survive.
4. Disruption of Metabolic Pathways: Some antibiotics, such as trimethoprim and sulfonamides, disrupt specific metabolic pathways required for bacterial growth. By blocking these pathways, the antibiotics deprive bacteria of essential nutrients and energy sources, leading to their death.
It's worth noting that antibiotics are ineffective against viral infections since viruses have different structures and mechanisms compared to bacteria. Moreover, the misuse or overuse of antibiotics can contribute to antibiotic resistance, which is a significant concern in healthcare. Therefore, it's crucial to use antibiotics responsibly, strictly following healthcare professionals' instructions and using them only when necessary for bacterial infections.

Antibiotics work by targeting and killing bacteria or inhibiting their growth. They do this by disrupting bacterial cell walls, interfering with bacterial protein synthesis, or blocking bacterial DNA replication. Antibiotics are selective for bacteria and do not affect viruses. The choice of antibiotic depends on the type of bacteria causing the infection and its susceptibility to the drug.
Antibiotics work by disrupting essential processes or structures in bacterial cells. This can either kill the bacterium or slow down its growth. Depending on the antibiotic, it may target the bacteria's cell wall, its DNA, or its ability to make proteins. Once the antibiotic has disrupted the bacterium's ability to function, the body's immune system can then clear the infection.
There are different types of antibiotics, which work in their unique way. However, the two main they work include:
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.
