Should antibiotics be more strictly regulated to prevent the rise of superbugs?

In today’s modern society, the use of antibiotics is becoming increasingly prevalent. Due to the global population’s increased usage of medicines, certain types of bacteria have developed antibiotic resistance, creating superbugs. Superbugs are bacteria resistant to multiple types of antibiotics, and have the ability to survive and even multiply despite antibiotic presence. This causes great danger to society, as individuals infected with these bugs cannot be treated because the antibiotics are made redundant. (State Government of Victoria, 2015) The looming threat of widespread antibiotic resistant bacteria raises the question, ‘Should …show more content…

Bactericidal antibiotics kill bacteria by interfering with the cell wall or organelle formation. (News Medical, 2004) Bacteriostatic antibiotics interfere with the cell’s metabolic processes, such as DNA replication and protein synthesis. (News Medical, 2004) Both actions inhibit the cells vital processes, causing cell death. (Crierie & Grieg, 2010) However, superbugs, such as strains of Staphylococcus aureus, and Mycobacterium tuberculosis are deadly as they are very difficult to treat due to their resistance to multiple antibiotics. (NPS MedicineWise, 2012) Previously, Staphylococcus aureus was treated with benzyl penicillin. Currently, however, the bacteria cannot be controlled through this method, as they have developed resistance, which occurs because bacteria have the ability to mutate. After antibiotic contact, bacteria can alter their DNA in a way that enables them to resist the antibiotics. Bacteria are prokaryotic organisms and produce asexually by binary fission, thus their offspring have no genetic diversity. The only source of genetic variation in bacteria is through mutation. (Crierie & Grieg, 2010) Mutation refers to changes in gene sequences, resulting in variation in subsequent generations. This process occurs in every millionth to ten-millionth cell. (Alliance for the Prudent Use of Antibiotics, 2014) Certain types of mutations cause different types of resistance. They may enable …show more content…

A huge advancement was made in the world of medicine when antibiotics were first invented. Suddenly, deadly diseases such as Staphylococcus could be cured. (Tan, 2014) Before antibiotic discovery in 1928, and their prescription in the late 1930’s, Streptococcus pyogenes caused 50% of post-birth deaths, and was a major cause of death in burn victims. Staphylococcus aureus killed 80% of people with infected wounds, and tuberculosis and pneumonia ran rampant within the population. Through the use of antibiotics, these diseases could be easily treated. Between 1944 and 1972, human life expectancy leaped by eight years, primarily accredited to antibiotics; and the number of people dying due to bacterial infection dramatically fell. (Australian Broadcasting Corporation, 1999) Therefore, antibiotics are beneficial as they are able to save lives, and treat various types of bacterial diseases. In addition they are easily administered - they may simply be taken orally, or injected. They are also cost-effective, and have few side effects. Moreover, the cost of antibiotic regulation, public ignorance of the threat, and adherence to routine are major factors preventing regulation laws to be put in place. (Krans,
