Bacteria Essay

pollution, specifically waterborne diseases. Waterborne diseases such as polio, cholera, hepatitis, and dysentery are awful diseases and considerably debilitating and in some cases fatal. These diseases are caused by highly pathogenic waterborne bacteria such as Clostridium botulinum, Vibrio cholerae, Shigella dysenteriae, and Salmonella typhi. The World Health Organization attributes the mortality of water associated diseases to over 5 million people a year, with 1.5 million of those deaths…

When trying to figure out the cellular morphology and arrangement the T-streak method is used to get isolated colonies from a sample of a bacteria. To begin the process a petri plate which has a layer of agar is divided into three sections in a T form. When preforming an experiment aseptic techniques are used between each step, therefore you flame the loop before and after every step. A sample is taken from a culture with an inoculated loop, then is spread in the top section of the plate in…

or plants as a spore. Attachment Uses the TCP acquired from V. Cholerae to attach to intestinal mucosal cells. Invasion Forms a biofilm along the intestinal wall, clearing nearby cilia and producing antibiotics that will kill nearby competing bacteria. Evasion The polysaccharide capsule obtained from B. Anthracis prevents engulfment by macrophages as well as preventing opsonization of the bacterium. Toxin…

1a.) The bacteria levels in the Boston Harbor were higher 25 years ago. "Historically, poorly treated wastewater and discharge of sewage solids, or sludge, were significant sources of bacteria to the harbor, documented as far back as the 1930s." (The State of Boston Harbor: Mapping the Harbor's Recovery, 8) Now, the water quality is being measured by the MWRA to meet the health standards of making the water 1b.)With the respect of my parameter, bacteria pollution, I could attend the Boston…

Overview Methicillin-Resistant Staphylococcus aureus is a pathogen that can cause a wide range of diseases in humans. It is a type of staph bacteria that’s immune to most antibiotics. MRSA is unique form of staph because certain antibiotics can’t treat it. MRSA becomes resistant to antibiotics if given enough time. MRSA bacteria is likely to grow when antibiotics are used too much or not properly. History MRSA was first identified in 1961 by British scientists. By the 1970s, MRSA had spread all…

you choose to accept it, is to fully characterize the molecule. If you are successful, you will definitely finish graduate school and move forward in your career as a scientist. (30 pts) a. Design an experiment to determine if “TLR23” recognizes a bacteria or a virus. What results do you anticipate and what experimental difficulties will you potentially encounter? TLR’s are toll-like receptors that are associated with resistance to viral, bacterial, parasitic and fungal infections. Flow…

what is needed for bacteria to be cultured in or on certain media. Culture media can either be liquid or solid, and they can be used to identify certain characteristics of different bacterial species. This is indicated by the growth or lack of growth in or on certain media. Solid media can also be used to isolate organisms and provide a means to observe their morphology (Wiley 55). The purpose of using enzymes to test bacteria is to differentiate and characterize them. Bacteria secrete certain…

Microbiology is the study of small organisms and or non living particles that are unseen to the naked eye. The microbes range from bacteria, to protozoa, parasites to virus. After studying them, scientists are able to identify various illnesses that are associated with microbes. These microbes are either directly or indirectly involved in most diseases. These in retrospect to their names cause bacterial infections, parasitical infections, fungal infections and viral infections. However, although…

after year with multiple reports. This bacteria has multiple strains and is known widely throughout America. Most strains of this bacteria aren’t normally fatal, but just like any other bacteria, under the right circumstances, anything can happen. Salmonella outbreaks continuously occur, its causation is known but sometimes not the easiest to prevent, the signs and symptoms can be easily read and a cure is known. Salmonella is a gram negative bacilli bacteria that commonly effects multiple…

Everyone carries harmless bacteria on their skin. These bacteria reside as normal flora on our skin and play a significant role in preventing harmful bacteria from invading our body. One form of bacteria that you may have already heard of is found in 1/3 of the human population and is causing quite a stir in the medical community because of it's growing resistance to many forms of antibiotics (CDC, 2016). This bacteria, nick-named a super bug, is known as Methicillin-resistant Staphylococcus…
