Bacteria Essay

Bacteria are a fundamental part of life on our planet, but they can also cause disease in our species. People have been using antibiotics for many years, but for the first time they are causing problems. Several years ago, it was discovered that some antibiotics has created strains of bacteria that are resistant to that antibiotic. One example of this is MRSA, or methicillin-resistant Staphylococcus aureus. This means that sick patients must find a different antibiotic or have no way to cure the…

Bacteria: Staphylococcus aureus Bacteria is a funny thing in the world of the living organisms. We, as humans, often look at bacteria as a germ or something that causes harm to our body but that is not the case. The Earth happens to widely depend on bacteria. We often forget that 99% of bacteria is good for us. We need these bacteria’s so they can occupy spaces in our body where else that 1% of bad ones will invade and make us sick. The bacteria, Staphylococcus aureus, happens to be one of…

The Extraordinary Science of Microbiology There are a wide variety of microorganisms in this world. The major groups of microorganisms include bacteria and fungi. These microorganisms are found all over the earth. The study of microorganisms started in the mid-1600’s. Most people believed that microorganisms only spread deadly diseases, but scientists proved that microorganisms can also be beneficial to human life. The wide variety of microorganisms that are found everywhere are most well…

It often used as a cryoprotectant. Glycerol can defend against cold temperatures by depressing the freezing point of the bacteria cells, enhancing supercooling. With bacteria, adding glycerol to final concentration of 15% will help protect from damage of freezing and thawing. When the freezing point of bacterial cells lowered by the use of glycerol, its prevent the formation of ice crystal which…

In everyday life, people use disinfectants, substances used to destroy viruses and microbes such as bacteria and fungi1, to clean their bathrooms. If not properly sterilized and cleaned, the bathroom can be a domain for numerous bacteria including ubiquitous Serratia Marcescens, a short, rod shaped, facultative anaerobic, opportunistic pathogen that can cause nosocomial infections such as urinary tract infections, bacteraemia, meningitis, sepsis and cerebral abscesses2. Facultative anaerobic…

Bonnie Bassler, an American molecular biologist, once stated, “When antibiotics became industrially produced following World War II, our quality of life and our longevity improved enormously. No one thought bacteria were going to become resistant” (Bassler, 2002). Bassler suggests how antibiotics can improve our livelihoods by treating health issues. However, there may be a long-term problem associated with increased usage of antibiotics, as there can be additional disease risks with the rise of…

growth in them. The agar plate that had the antibiotics, but not the plasmid had no growth because the bacteria was not introduced to the plasmid that had the antibiotic resistant gene.The LB/amp had growth to it because it was not introduced to any new molecules or chemicals. The po The other plates had growth because they was introduced to the antibiotic resistant gene that made the bacteria able to grow. The positive control of the experiment was the LB plate, because the environment was not…

lanthionine and didehydroalanine. It is a substance produced by both gram positive and gram negative bacteria to control the growth of other bacteria species to reduce competition for substrate and space. Nisin has received attention from researchers making it the most exploited bacteriosin (Shetty, Pometto and Levin, 2006). The attention from bacteriologist is due to its effects against gram positive bacteria that are usually common food spoilers and pathogenic. Industrial microbiologists have;…

drug is bacterial diseases. Penicillin is thought to be the first antibiotic ever founded. The discovery of penicillin was on accident though. The man who discovered the lifesaving drug was Alexander Fleming, a Scottish scientist who was researching bacteria at the time of the discovery. His complete lack of organization…

several online sources that contain materials on the impact of Legionaries’ Disease to public health and its association with the role of a Public Health Inspector/Environmental Health Officer. Legionaries’ Disease is caused by roughly 35 Legionella bacteria species, with symptoms of severe pneumonia and psychological changes. (Canadian Centre for Occupational Health and Safety, 2015) With an increase of the elderly population in North America and the use of statistical data, the predicted trend…
