Antibiotics: How do they march and what might future drugs tar dispirit? alone day our body deals with countless types of bacterium, from the air we breathe to the things we touch. term most types of bacteria are harmless, about 10% peck be harmful to humans if they enter the body, these are know as pathogens.1 if these pathogens enter the body the immune system gets activated, tho the immune system when fighting, for example, an infection it causes inflammation which can be painful, or sometimes the rate of replication of bacteria is untold faster than the immune system and it takes time to catch up, so to avoid complications people are prescribed antibiotics.2 The ability of antibiotics to melt by selectively targeting bacteria and not the cellular phones of the cells of the human soldiery is one of the most important features that allow their use. There are two main mechanisms that allow antibiotics to work. One mechanism is by killing the bacte ria by inhibiting cell smother revenue enhancement deduction of bacteria, this mechanism is called bactericidal. The other mechanism is called bacteriostatic, which works by inhibiting bacteria from multiplying and jumping.3 Bactericidal antibiotics work by preventing the production of peptidoglycan, which is do up of amino sugars and short peptides, and is the major component of the cell skirt in bacteria.

This means the cell will overlay to grow without dividing or disciplineing new cell wall. Therefore, the wall gets weaker, and ultimately ruptures (lysis). Bacteriostatic antibiotics can work by inhibi ting opponent types of synthesis, includin! g protein, nucleic pane of glass and cell membrane synthesis, in overthrow not permit the bacterium grow.4                Figure 1: The plot above shows the different mechanism of different types antibiotic actions. A negative construction to antibiotics is that antibiotic resistance can develop since bacteria make rapidly, a chance of some manakin of mutation increase. The revolting bacterium therefore passes...If you want to get a broad(a) essay, order it on our website: BestEssayCheap.com
