As a child I remember two instances, one was the story my father used to tell me about the Cuyahoga River catching fire in Cleveland Ohio. The other was my personal brush with hot tub folliculitis as a teenager. The Cuyahoga River was known as one of the most polluted rivers in the nation. This river had caught on fire at least 13 times between 1868 and 1969. These fires causing millions of dollars of damage every time taking out boats, bridges and buildings near by. The fire of 1952 was the

A. Describe the difference between an obligate and facultative aerobe. Obligate aerobes are bacteria that require oxygen for growth. They will only grow at the top portion of the culture media where it meets the air and has a lot of oxygen. Facultative aerobes grow based on what is available to it. They prefer oxygen but oxygen is not necessary for growth. These aerobes mainly cluster at the top of the culture media where they have a high concentration of oxygen but will dispersed throughout

(a) sensitivity to antimicrobial agents, (b) resistance to phagocytosis, (c) chemical composition, and (d) decolorization by alcohol. Gram-positive bacteria differ from gram-negative bacteria in the structure of their cell walls. The cell walls of gram-positive bacteria are made up of twenty times as much murein or peptidoglycan than gram-negative bacteria. These complex polymers of sugars and amino acids cross-link and layer the cell wall. The thick outer matrix of peptidoglycan, teichoic acid, polysaccharides

which classifies them as an acid fast bacterium. Mycobacterium are the rod shaped aerobic bacteria. 2. Pseudomonas may be resistant to disinfectants dependent on which surfaces may be disinfected with which product. 3. Bacillus are often resistant to disinfectants as these gram-positive rods have the ability to form an endospore. Endospores can survive environmental changes and usually kill the bacteria. When extreme cases of high temperature, high UV irradiation, desiccation, chemical damage

up with many different types of microorganisms and one of them is called bacteria. There are good bacteria and bad bacteria. When the bad bacterium multiplies with in the human body it causes what is known as bacterial infections. Although a bacterium is a microorganism it also has several cellular structures. The structures with in bacteria that cause us to become ill are Fimbriae, Plasmid, and the Capsule. Only the bacteria that contain these three structures can cause disease in a human body.

What can we do about Antibiotic-Resistance Bacteria? After completing the assigned activity I learned that there were a few points of evidence that demonstrated the problem of antibiotic resistance. I also found recorded data of methods that have been successful in decreasing the number of antibiotic-resistant bacterial strains and some methods that were not so successful. Since the 1930’s antibiotics have been administered to treat several types of infectious diseases. The unearthing discovery
