It is said that fungi, bacteria, animals and plants make poisons that we might be able to use
as cures. Alexander Fleming was a Scottish biologist and pharmacologist. He observed
how different organisms produce toxic chemicals that incapacitate bacterial species in
complex microscopic ecosystems. In 1928 Fleming observed a Petri dish was
contaminated by mold and as result to this it killed a bacterial culture. This accidental led
him with the discovery of penicillin which it was the first antibiotic drug.
“Most new antibiotic drugs are derived from natural sources. These compounds disrupt
critical functions in bacterial cells without harming human cells. Yet, bacteria eventually
evolve to become resistant to these medications. Today, new strains of bacteria, including
those that cause tuberculosis can resist most, and in some cases, all available antibiotics.
Widespread use of antibiotics is accelerating the process.”
The first resistant strains were reported in 1947. Between the years of 1992 to 2000 the
methicillin-resistant increased approximately by 25%. Staphylococcus aureus as also
knows as “Staph” and “MRSA” is a bacterium found in the human respiratory tract and
also on the skin. “Staph bacteria occur when the bacteria penetrate the surface of the skin
though cuts or scrapes and grow within deeper tissues or enter the blood.” MRSA was first
found in prisons and hospitals. MRSA is really a nerve-racking because it can cause
