Antibiotic and Penicillin



Antibiotics are chemical substances that are secreted by living things. Doctors prescribed these medicines to cure many diseases. During World War II, it treated one of the biggest killers during wartime - infected wounds.
It was the beginning of the antibiotic era. But just when antibiotics were
being mass produced, bacteria started to evolve and became resistant to these
medicines.
There are people who believe that when they get sick, antibiotics are the answer. The more times you use a drug, the more it will decrease the effect it has on you. There is tow reason, one of them is the bacteria has found a way to avoid the effects of that antibiotic. Another cause of resistance is the improper use of drugs. When patients feel that the symptoms
of their disease have improved, they often stop taking the drug. Just because
the symptoms have disappeared it does not mean the disease has gone away.
Prescribed drugs should be taken until all the medicine is gone so the disease
is completely finished. If it is not, then this will just give the bacteria
some time to find a way to avoid the effects of the drug.





















Penicilin is one type of antibiotic that have a long lasting effect in history.
The difference between penicillin and antibiotic is, antibiotics kill disease-causing bacteria by interfering with their processes, but penicillin kills bacteria by attaching to their cell walls became the most powerful germ-killer known at that time.
