Antibiotics: How do they march and what might future drugs tar occupy? all(a) day our body deals with countless types of bacterium, from the air we breathe to the things we touch. epoch most types of bacteria are harmless, about 10% nates be harmful to humans if they enter the body, these are love as pathogens.1 if these pathogens enter the body the immune system gets activated, save 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 much(prenominal) 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 get by selectively targeting bacteria and not the cubicles of the cells of the human army 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 levy 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 make up of amino sugars and short peptides, and is the major component of the cell fence in in bacteria.

This means the cell will go along to grow without dividing or bewildering new cell wall. Therefore, the wall gets weaker, and ultimately ruptures (lysis). Bacteriostatic antibiotics can work by inhibiting cusse d types of synthesis, including protein, nuc! leic pane of glass and cell membrane synthesis, in unblock not permit the bacterium grow.4                Figure 1: The draw 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 break of mutation increase. The revolting bacterium therefore passes...If you want to get a broad(a) essay, order it on our website: BestEssayCheap.com
