INTRODUCTION Antibiotics The word antibiotic comes from the Greek anti meaning ‘against’ and bios meaning ‘life’ (a bacterium is a life form).’ Antibiotics are also known as antibacterials, and they are drugs used to treat infections caused by bacteria. Bacteria are tiny organisms that can sometimes cause illness to humans and animals. The singular word…
The Effect of Different Antibiotics on Bacteria
Antibiotics are medicines that kill bacteria. Bacteria can cause infections such as strep throat, ear infections, urinary tract infections, and sinus infections (sinusitis). There are many types of antibiotics. Each works a little differently and acts on different types of bacteria. Don’t antibiotics cure everything? Antibiotics are powerful medicines, but they cannot cure everything. Antibiotics…
Effect of Hormones and Pesticides on Environment and Humans
To what extent is the use of hormones, pesticides and antibiotics a threat to the environment and human’s health? INTRODUCTION: Hormone, pesticides and antibiotics are being used extensively in food production so as to be able to cater for an increasing global population. Though these have been used for decades but with the upcoming of…
The Effectiveness Of Methods To Control Microorganisms Health Essay
In the following assignment I will discuss the effectiveness of methods to control microorganisms in particular I will highlight the methods such as temperature, Immunisations and antibodies. Temperature is a huge factor in the growth of microorganisms along with food supply, pH levels and time. Refrigeration and freezing play a role together in the growth…
Antibiotic Resistance: Genetics and Mechanisms
Antimicrobial resistance occurs when a microorganism such as bacteria, viruses or parasites acquire the ability to disable the effects of a drug designed to kill them or stop their growth (CDC, 2018). As a consequence the treatments to get rid of infections failed and the risk to spread to others increased (WHO, 2018). Antibiotic Resistance…
Carbapenem-resistant Enterobacteria (CRE) Treatments
Current effective antibiotics for the treatment of infections caused by carbapenem-resistant enterobacteria (CRE) and the likelihood that these antibiotics will still be effective 10 years from now. Treatment options for CRE infections are very limited and resistance to antibiotics currently in use is rising. Polymyxins such as colistin and polymyxin B have been widely used…
The Rise of Antibiotic Resistance
Abstract The discovery of antibiotics was one of the most groundbreaking innovations of medicine. This healthcare staple, responsible for treating diseases that once were incurable, is now becoming less and less effective due to antibiotic resistance. The bacteria responsible can become resistant to this medicine by genetic mutation through reproduction or from other bacteria via…

Effects of Different Antibiotics on E.coli Growth
The effects of antibiotics on the growth of Escherichia coli have been found in several studies and some recent studies have also focused on the tolerance and reduced growth levels in bacteria to examine the molecular changes that allow such as change. E. Coli and anti-microbial agents: In a study by Dixon et al (2004),…
