of a Gram positive coccus genus of bacteria. Several biochemical tests will be performed to aid in the identification of this unknown bacterium. Biochemical tests are a series of tests used to identify certain bacterium The various tests that are used in this lab are the catalase test‚ oxidase test‚ blood hemolytic test‚ MSA‚ blood agar‚ and PEA/ab sens test. A known Gram positive coccus bacteria will be used alongside an isolated Gram positive unknown bacteria for comparison to aid in the ability

on why bacterium evolves. Bacteria are single celled (eukaryotic) organisms. Bacteria is present in almost every environment‚ including the human body. They can absorb nutrients from various ways‚ some bacteria are photosynthetic meaning they absorb their nutrition from sunlight through a process known as photosynthesis‚ while other bacteria absorbs nutrients from the organism they live on or in. There is good bacteria and more dangerous “bad” bacteria. Bad bacteria can be dangerous to other species

French Fries vs Bacteria Introduction After the Chipotle scandal of having E. Coli‚ I wondered what other bacteria can possibly be on foods that we consume. In addition‚ eating my french fries the day after I bought it‚ I wondered how long it could be until there was bacteria growing on the french fries. These two experiences in the last few months triggered me to become interested in what bacteria is and how harmful it can be. In order to do this investigation‚ one must study various types of french

MICROBIOLOGY 3444-007 Gram Negative Unknown Unknown Bacteria #14 LeNaiya Kydd 4/2/2014 Abstract In order to be able to identify the unknown organism that was given to us‚ we had to conduct a number of different tests. These biological tests are used because they help us be able to identify the properties of the unknown we have and be able to compare our observed results with actual results of all the potential organisms. When all of the data of the test are put together it is easy to

Antibiotic Resistant Bacteria in Hospitals. Introduction Antibiotic resistant bacteria are bacteria who can survive after exposure to one or more antibiotics. Some bacteria present today can even be resistant to multiple antibiotics and these are sometimes referred to by the name Multidrug resistant (MDR). Today many clinically important bacteria are MDR’s and this is a direct result of past decades of antimicrobial use and misuse. If an infection results from this sort of resistant bacteria a stronger antibiotic

Similarities and Differences Bacteria and archaea both share the fact that they are single-celled prokaryotic microorganisms that lack membrane enclosed nuclei. It has been discovered that the two typically can be found to have the same size and shape as one another. “They are both found occurring as rods‚ cocci‚ spirals‚ plates‚ coiled etc.” ("Archaea vs. Bacteria‚" n.d.). Both organisms use the flagella to swim and also reproduce by means of binary fission. On the surface these similarities can

BETWEEN PLASMID AND CHROMOSOMAL DNA IN BACTERIA. Eukaryotes have two or more chromosomes‚ prokaryotes such as bacteria possess a single chromosome composed of double-stranded DNA in a loop. DNA is located in the nucleoid of the cell and is not associated with protein A plasmid is an extra-chromosomal DNA molecule separate from the chromosomal DNA which is capable of replicating independently of the chromosomal DNA. Plasmids usually occur naturally in bacteria. A chromosome is an organized

"The Equal Pay Act of 1963 was passed to prohibit wage discrimination on the basis of sex and sought to ensure that women earn equal pay for equal work. Its purpose was clear: Eliminate the gender wage gap‚ which hurts women and families. But 50 years later‚ pay discrimination is alive and well. Gag rules that require employees to keep their pay secret perpetuate this inequity." (www.cnn.com) I as a women have personally experienced this in the workforce; where male workers are paid a higher salary

within 24 hours by diarrhea. As the disease progresses‚ the diarrhea becomes watery and then may become bloody. E-Coli symptoms sometimes include vomiting and fever. The incubation period for E-Coli infection (i.e.‚ the period from ingestion of the bacteria to the start of symptoms) is typically 3 to 9 days‚ although shorter and longer periods are not that unusual. An incubation period of less than 24 hours would be unusual. In most infected individuals‚ the E-Coli symptoms last about a week and resolve
