activity of silver in general‚ and of silver nanoparticles in particular‚ is of significant interest because it appears to be independent of the strain of bacteria. Crucially‚ antibiotic resistant strains‚ MRSA (methicillin‚ or multiple-resistant Staphylococcus aureus)‚ E. coli O157‚ and others are affected by silver [6]. The reasons for this are not fully clear as yet‚ but could be related to mechanisms of silver ion action on bacteria [110]‚ trypanosomes and yeasts‚ all of which can take up and concentrate

Communicable Disease Paper Kayla Lysak HCS 457 July 7‚ 2014 Lindsay Cogan Communicable Disease Paper This paper will be discussing what MRSA is and the efforts that are being made to control it. It will also be discussing the environmental factors that are related to this disease. Other factors that will be discussed will be to explain the influence that lifestyles‚ socioeconomic status and disease management play and what the public health department is doing to reduce the threat this disease poses

Biology 1003 - Cells: Size‚ Structure and Microscopy Introduction What is life? What are the key factors that biologists have defined that apply to every single organism on the planet? In the 17th century‚ due to the amazing advancement of the microscope‚ biologists created a theory to differentiate the living from the non-living called the cell theory. One concept from the theory is that all living organisms are composed of one or more cells. The importance of studying cells is akin to the

Biological Evolution is the process of change and modification through a species of organisms. Evolution accounts for a species progression in developing and advancing through each generation better suited for the surrounding environment. The process of evolution will never end until the environment in which the species is contained in stops changing for millions of years. Though evolution is a proven fact many people still don’t accept it due to religious views and beliefs conflicting with the theory

I also sterilized the top of the test tube just for contamination purposes. Next I dipped my inoculation loop into the test tube to gather a sample of Staphylococcus aureus. Once I had my sample‚ I then began using the strike method to inoculate my TSA plate. I made sure to flame sterilize my loop between each strikes. I continued on using this same process to inoculate the three remaining TSA plates with

staining is the Gram Staining‚ as it is highly dependent (McCarthy‚ 25). In the specific experiment that was done‚ Gram Staining was used and the bacteria that was found was purple and round (cocci) shaped. Through this the bacteria was identified as Staphylococcus epidermis. Material and Methods: The first step to identifying the bacteria was to heat fix it to the slide. The materials used were a slide‚ water‚ a Bunsen Burner‚ bibulous paper and clothes pin. The unknown bacteria was in a vial in solid

Different bacterial genera including Alcaligenes spp.‚ Bacillus spp.‚ Corynebacterium spp.‚ Escherichia spp.‚ Micrococcus spp.‚ Pseudomonas spp.‚ Shigella spp.‚ Staphylococcus spp. and Streptococcus spp. were isolated from the collected samples. The bacterial community was found to be diversified where the concentration of tannery waste was less; thereby it was assumed that the tannery waste might affect the aquatic
