Bacteria Essay

barriers had been breached. The infection caused by this bacteria can be spread in different modes such as direct contact from an infected wound, contact with the hyaluronidase, an enzyme produced by the bacteria that destroys tissues or even skin to skin contact with an infected person. There are some difference in characteristics between Gram-positive and Gram negative bacteria, where one of most distinctive differences is that Gram-positive bacteria composes of a thick layer of…

infected by foreign bacteria, the infectious agents travel through the body via the bloodstream and the lymph nodes. After this infection occurs these bacteria now, in the body are planktonic. This means they are individual, free swimming, and virtually functioning as single celled organisms. When these bacteria are threatened by the host’s immune system or antibiotics they form biofilms. A biofilm is a thin coating of organic as well as inorganic matter that contains bacteria that have fused…

Bacteria is a broad domain of the prokaryotic cells in which are very small containing of no nucleus, a small amount of organelles and a single chromosome loop. Bacteria reproduces asexually through binary fission meaning it duplicates its genetic material and then divides into two parts. Bacteria can also exchange genetic material through conjugation, when DNA is directly transferred from one bacterial cell to another, the two bacteria then merge and share the genetic material. There are two…

What are disease-causing bacteria and how harmful could they be? By their name, disease-causing bacteria are bacteria that cause disease. The effects that they have on the human body, or any living organism, can range from mild to severe. Fortunately, we have antibiotics to help prevent the spread of infection and protect our bodies against infectious bacterial diseases. Antibiotics, also called antimicrobial drugs, are drugs that fight off infectious disease caused by bacteria. With the…

would divide prokaryotes into the following two groups: archaea and bacteria. Thus, the development of the three domains was created to include archaea, bacteria, and eukaryotic domains. During the course of this Session Long Project I will define the general characteristics which determine whether a prokaryote belongs to the Archaea or Bacteria domain. I will define and discuss the role in which DNA and…

E coli Name: Course: Lecturer: Date: E coli Introduction Escherichia coli are bacteria although this is a large group of a scientific classification. It includes a diverse classification of these types of bacteria. E. coli occurs in different forms or strains with most of these strains being very harmless. However, there are other strains that are very harmful and can cause one to be sick. Some of these strains can cause diarrhea and in most cases urinary tract infections…

common infection are shown in their patients, as there is no accurate diagnostic testing for bacterial infections. Bacteria become resistant to antibiotics through overexposure. On the other hand many people believe that the prescribing of antibiotics is important. It keeps the disease at bay and ensures a healthy population. (Anon, 2016) Antibiotics are substances that kill bacteria or stop their growth. They don’t work against viruses, as viruses live and reproduce inside cells. Penicillin…

main topics could be the drug resistance mechanisms of bacteria. 2. First, spontaneous mutation which changes the drug target or upregulate drug efflux. Second, Horizontal gene transfer (HGT) that the genes in bacteria acquire to become resistant. HGT can cause multidrug resistance in a genetic event which make the bacteria become resistance. Third, the ability of bacteria that they can form biofilm while they are being infected. The bacteria provide themselves protection to against the drug…

infection commonly called strep throat is caused from streptococcus pyogenes. Group A streptococcus or GAS is a bacteria commonly found in the throat (strep throat) and on the skin (scarlet fever). This bacteria can cause severe infections and mild infections such as strep throat. GAS was identified around 1879 when Louis Pasteur isolated a strand of the bacteria. Later, the bacteria was given the name streptococcus pyogenes. However, historians studied medical records and it seems to be that…

After completing several thorough procedures to discover my unknown bacteria, bacteria #304, it was discovered to be Escherichia coli or for short E.coli. I can conclude that my answer is correct because several tests were conducted leading me to the specific bacteria. The first step taken to discover the unknown bacteria was a gram stain. A section of the unknown bacteria was taken and stained with crystal violet and safrinin so that the bacterium was visible under a microscope. The gram stain…
