Coliform bacteria

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…

population dynamics of natural bacteria (Deresinski 2008). Bacteriophages attach to their host cell by specialized structures called tail fibers, inject their nucleic acid into the bacterium and hijack the host cell machinery. Exploiting the host cells replication, translation, and transcription machinery, the phage produces many copies of its nucleic acid and capsid proteins. The escape of mature viruses takes…

coli, in a water source is an indication of the presence human or animal waste matter in the water. These bacteria are a type of fecal coliform bacteria found in the intestines of humans and animals. Drinking water that contains E. coli bacteria may cause diarrhea, abdominal cramps, headaches and nausea. Young children and elderly people may be more susceptible to the adverse effects of E. coli because their immune systems…

Escherichia Coli, or E. Coli, are a large and diverse colony of bacteria within the fecal coliforms group – a group of closely related bacterial genera that share the ability to metabolize sugar lactose, producing acids and gas as byproducts – found living harmlessly in warm-blooded organisms’ intestines, the environment, or in various foods (2006). Unfortunately, some forms of E. Coli bacteria are pathogenic, in which the bacteria has developed the ability to cause the disease of the urinary,…

Resistance of Ordinary Bacteria to Penicillin Russell, Bradley BSC111L 4 Nov. 2016 Introduction Antibiotic resistance is a problem that is occurring more and more rapidly across the world. Antibiotic resistance is when antibiotics have lost the ability to control or kill bacteria. The bacteria become resistant to antibiotics and continue to multiply. This is causing medical and science communities to grow more and more uneasy as therapeutic levels of antibiotics are becoming less and…

With the rate at which our planets population is growing, what are we going to eat when we run out of room to plant crops, raise animals? There is always the option of genetically modified organisms or GMO’s, meats that are grown in labratories, algae, or even insects, but all of these are “temporary fixes” to the real problem. How can we sustainably survive on this planet at all if we continue down this path of over consumption? According to the Non GMO Project, GMO’s are defined as living…

This colonisation begins at birth with pioneer species, depending on physiochemical factors. The normal flora inhibits the skin, oral cavity, upper respiratory tract, gastrointestinal tract, urogenital and conjunctival membranes. They are commensal bacteria; getting shelter and nourishment from the host without causing harm (Gould, 2012). To a healthy individual, most normal flora is harmless, however some have pathogenic potential and to a compromised individual can cause infection and…

journey to the microscopic world of bacteria can be likened to a child exploring the world for the first time. As the child discovers the world, she also learns several survival skills along the way. In the same manner, all the knowledge I learned from Microbiology class and laboratory sessions regarding microbial world equipped me to identify bacterial unknowns from a clinical sample. The task was to successfully separate and accurately identify two bacteria of a specimen taken from an…

Identifying a bacteria based off of physical characteristics is almost impossible due to the commonality of shapes and physical features. Because of this, a wide range of biochemical tests were preformed in order to better identify the bacteria. Being able to identify an unknown was the most interesting part of the microbiology lab this semester, as well as, being able to preform the various tests. Proper aseptic technique was used throughout the semester and followed during all biochemical…

antibiotics. However, some bacteria are known for causing diseases such as the common cold, AIDS, Herpes, and Chicken Pox. Knowing the identity of microbes is essential for knowing the causative agent of a disease in order to provide patient’s effective treatment. The purpose of this lab is to identify the unknown bacteria that was given. Applying all of the techniques that have been learned in the lab will help identify and distinguish the unknown bacterium. While identifying the bacteria, it…
