The creation of antibiotics has benefited the medical field in unimaginable ways. This resourceful medication has eradicated infectious such as AIDS virus, tuberculosis, malaria, and other infectious diseases for several decades. They had once pose great threats to the human existence but now have been put under control because of antibiotics. However, recent studies have shown that the diseases though to have been eliminated are beginning to resurge along with the appearance of new unknown ones.
The only possible explanation for this phenomenon is the growing resistance and evolution of the microorganisms to the antibiotics. Each time an antibiotic is taken to fight bacteria, there are always some left to survive the drug (Evolution). This is because it is inevitable that random mutations will occur, eventually protecting the microorganisms against the drug. The more an antibiotic is used, the more resistant the mutations of the disease will become. When patients cut short the full course of drugs, the resistant strains have a chance to multiply and spread (Evolution).
Streptococcus pneumoniae, commonly known as Pneumonia, is a perfect example of a virus that has genetically mutated over time to become immune to certain antibiotics. To start off, pneumonia is an infection of one or both lungs which is usually caused by bacteria, viruses, or fungi (Schiffman). Prior to the discovery of antibiotics, one-third of all people who developed pneumonia subsequently died from the infection. Most of the time, pneumonia is contracted by breathing in droplets of any substance that carry the organisms responsible for pneumonia (Schiffman). Once the bacteria enter the lungs, they reside in the air sacs of the lungs and rapidly multiply. Over time, the lungs till be filled with fluids and pus because the body is trying to fight off the infection (Schiffman).
The streptococcus pneumonia organism has drastically evolved over the past few decades. It was once a virus that was...
