Essay on Bacteria

Phones hold an alarming amount of bacteria on them, being that every 8 in 10 phones hold pathogenic bacteria. A pathogenic bacteria is a type of bacteria that will get a person sick and can be potentially life threatening. A common type of pathogenic bacteria found on phones is e.coli. E.coli is a bacteria that can be obtained from uncooked meats, unsanitized water, and anything fecal contaminated. Although e.coli can be a dangerous bacteria outside of the body, it plays an essential role in the

Antibiotic Resistance in Bacteria For about 50 years, antibiotics have been the answer to many bacterial infections. Antibiotics are chemical substances that are secreted by living things. Doctors prescribed these medicines to cure many diseases. During World War II, it treated one of the biggest killers during wartime - infected wounds. It was the beginning of the antibiotic era. But just when antibiotics were being mass produced, bacteria started to evolve and became resistant to these medicines

Clostridium botulinum Clostridium botulinum: A group of gram-positive, rod-shaped bacteria commonly found in nature. The bacteria form heat-resistant spores which allow them to survive in a dormant state until exposed to favorable conditions that support their growth. As C. botulinum grows best in anaerobic conditions, the bacteria and its spores occur in soil, bottom sediments of streams, lakes, and coastal waters, as well as in the intestinal tracts of fish and mammals, and in the gills and viscera

“Drug Resistant Bacteria According to Cable News Network, reported that, “the Center for Disease Control is categorizing antibiotic-resistant organisms by threat level. That’s because, they have estimated, more than 2 million people get antibiotic- resistant infections each year, and at least 23,000 died because current drugs no longer stop their infections” (Falco,1). Antibiotic-resistance is becoming a growing issue in society today. “A 59-year-old man was hospitalized with Klebsiella pneumonia

ability to kill or hinder the growth of bacteria. Antibiotics contain compounds that are naturally produced by organisms to combat diseases caused by microbes. Discovery of penicillin by Sir Alexander Fleming became the first stepping stone of many new antibiotics of today’s modern medicine. Antibiotics typically invade the very components that make up bacteria, such as cell walls and metabolic pathways (Sato et al., 2014). However, frequent mutations of bacteria cause today’s strains to become more

of garlic when exposed to two different strains of bacteria. Garlic has been used throughout many centuries to treat common ailments from seasickness to intestinal parasites (Ankri and Mirelman, 1999). With the information gathered from this lab, we can conclude whether or not our predecessors were on the right track with this natural remedy. Another reason for doing this experiment is to observe how natural antibiotics affect modern bacteria. With our modern medicine, people are diagnosed with

Gut Bacteria Can Be Important with Diabetes Though the term gut bacteria might sound yucky, this bacteria that lives naturally in your bowels is beneficial. International research has revealed gut bacteria could help in the prevention and treatment of health problems such as diabetes and obesity. Discover how gut bacteria, also known as “good bugs.” can be important for people with diabetes. Major issues for people with diabetes include inflammation, insulin resistance and weight gain. A recent

Abstract Some bacteria are able to go through transformation making new combinations of genes. Transformation is a way of gene variability in bacteria. This experiment is based on the transformation mechanism of bacteria and gene regulation. The bacteria used for the experiment was Escherichia coli and the genes introduces for the transformation were: gfp and bla by a pGLO™ plasmid. After the insertion of the target genes and growing the bacteria on specialized LB media, it could be seen that the

Bacteria possess various mechanisms that allow them to sense and migrate towards prey and food sources. These mechanisms include use of flagellar motility, using chemokinesis and spirochaetes. Predatory bacteria have been known to have many biotechnological applications including antibacterial resistance alternatives. Using the example of Bdellovibrio bacteriovorus this is a suitable example of predatory bacteria and has been suggested to have biotechnological applications. Bacteria’s movement

After gaining some knowledge about bacteria, we were giving an investigating bacteria growth lab to do. Our objective was to observe the conditions required for bacteria to grow and to test the effectiveness of substances that may be antibacterial, disinfecting, and or sanitizing. My group and I began our procedure by gathering all the bacteria by swabbing our necks and mouths. After this, we inoculated the culture by rubbing the bacteria on the agar, a nutrient rich gel made from sea kelp, on the
