Antibiotic Resistance:
It has been called the miracle drug, and saviour. It is used on a daily basis to treat a plethora of infections, and to prevent others from occurring. This miracle is antibiotics. A chemical synthesized by or extracted from micro-organisms that eradicate other micro-organisms. Antibiotics kill bacteria in a variety of different ways, from inhibiting cell wall synthesis to inhibiting specific bacterial metabolic pathways. The phenomenon of antibiotic resistance, only now in the world spotlight, has been present since the beginning of time. The increase in antibiotic resistance can be attributed to sociological, ecological, and genetic factors. These include overuse, random mutation, horizontal gene transfer, and selective pressure. In light of these new discoveries the world has come to realise the seriousness of this event. If the rate of antibiotic resistance is not slowed or reversed, the world could face epidemics of infectious diseases, and may be forced into a situation where antibiotics would be futile in the war against harmful flora. To facilitate the search for a cure for antibiotic resistance, one must first understand the characteristics of antibiotics and then analyze the methods that bacteria use to attain resist
The continuous overuse of antibiotics by humans will lead to resistances that could cause catastrophic damage to our lives, and economy. Numerous studies have been done on prevention and regression of antibiotic resistance. The main focus of these studies has been on finding an “optimal” rate at which an antibiotic should be used: minimizing resistance, and maximizing efficiency. This number is difficult to attain due to the numerous ways in which antibiotics are misused. Antibiotics are over consumed in communities and are prescribed by doctors unnecessarily. They are also extensively used in growing crops, and raising livestock. In developed countries, approximately 50% of all antibiotic consumption is used for animal therapy (used as growth promoters). Besides aiding antibiotic resistance, the use of antibiotics in agriculture, also helps spread resistance. Resistance is passed from one organism to another or even from animals to humans through the food chain. Antibiotic residue left in the environment is yet another problem that is generated. The full impact of antibiotics excreted in the feces of animals and humans is yet to be realised. After observing the various ways of acquiring and spreading resistance it is not difficult to understand that once curable infections such as gonorrhoea, tuberculosis, and malaria have become almost untreatable. While researchers search for a “cure” to antibiotic resistance, it is common belief that the complete reversal of resistance is at best a distant scenario. To fight antibiotic resistance, each individual must put forth a full effort. Studies show that simply reducing antibiotic usage will not reverse resistance. But it is encouraging to find that cases of resistance can be dramatically reduced (from 10-80%), by using various methods of prevention. Scientists believe minimizing quantity, duration of therapy, and spread of resistance are vit
