Antibiotics are medications which assist in fighting bacterial infections by killing or halting the bacterial development and for this reason these medicines are also concern to as anti - bacterials.(1 , 2)Antibiotics lie in of miscellany of potent drugs for treatment of diseases or illnesses triggered by bacteria . The authoritative matter to know is that antibiotics can not be used for care for viral infection , such as flu , cold and legal age of coughs .
In this article , we will discuss what exactly are antibiotics ; who key out the first antibiotic ; the mechanism of antibiotic drug ; their side effects ; and all about antibiotic electric resistance .
Important Facts About Antibiotics(1, 2, 4)
What are Antibiotics?(1, 2)
antibiotic drug are one of the uncouth medicament prescribed by the doctor for treatment of diseases triggered by bacterium . Antibiotics are one of the powerful drugs that can fight bacterial infections and save many life when used at the proper time and in the right manner .

The white blood cells are responsible for for attacking the disease stimulate bacteria in showcase of symptom and the immune system often can ward off the infection . In guinea pig where there is presence of surplusage of the disease causing bacterium and when resistant system can not fight the contagion or demolish the bacterium , this is where antibiotics enter to fight the infection .
Penicillin: The First Antibiotic Ever!(3, 4)

Modern Antibiotics
There are dissimilar type of modern antibiotics available too and can be normally bought with prescription in many countries . Another fluctuation of antibiotics is topical antibiotics , which are available as over - the - counter ( OTC ) emollient and creams .
Antibiotic Resistance(1)
There are lots of worry about the overuse of antibiotics which is also conceive to give in the increasing bacterial transmission , which are develop a electric resistance to antibiotic drug .
The Centers for Disease Control ( CDC ) also says that there has been an increase in the antibiotic overuse . The use of antibiotic seems to be more in certain areas , such as the Southeast region.(5 )
The exercise of a major course of instruction of last - line antibiotics , which is carbapenems , has significantly increased from 2007 to 2010 .

Antibiotics are completely and perfectly ineffective against virus or viral infection.(1)Most of the upper respiratory tract contagion are triggered by virus , such as the flu and unwashed cold . antibiotic drug are incapacitated when it comes to struggle these viral infections.(1 )
Development of Antibiotic Resistance
If the antibiotics are used wrong or are overdrive then the causative bacterium can become insubordinate to an antibiotic , meaning that the antibiotic drug lose its potency against that particular form of bacteria , because the bacterium has become used to the antibiotic and has been able-bodied to meliorate its defenses .
A broad - spectrum antibiotic can be used to handle broad range of contagion ; whereas a narrow - spectrum antibiotic drug is used for treat only certain infection as it is only effectual against some physical body of bacteria .
There are some antibiotic drug which fight aerophilous bacteria and some which fight anaerobiotic bacterium . aerophilic bacterium command oxygen ; whereas anaerobiotic bacteria do not have such requirement .
Prophylactic Use of Antibiotics
In certain cases , the doctor will prescribe antibiotic drug to prevent rather of treating bacterial transmission , such as is the case before perform any operating theater . This is consult to as preventative use of antibiotic drug .
