MICROBIOLOGY What is the purpose of general growth media‚ selective media‚ and differential media? Give examples of each. General Purpose Media General Purpose media is designed to grow most organisms and do not contain growth inhibitors. Standard Methods Agar and Blood Agar Bases are examples of general purpose media. Differential Media Differential media contain a component that allow an observable change when a specific chemical reaction takes place. Simmons Citrate Agar is an example

Microorganisms are classified according to their structure. By means of flow charts‚ diagrams and tables explain the differences between Viruses‚ Bacteria‚ Cyanobacteria‚ Achaea and Fungi. Bacteria or bacterium are unicellular microorganisms. They are essentially only a few micrometres long and form of various shapes including the spheres‚ rods and spirals.

H1N1: The Sneaky Killer I chose to write my topic paper on the H1N1 virus. This virus has interested me since its reemergence in 2009. Its ability to change and adapt each time it shows up again attracted my attention. I hope to inform people about the virus along with the symptoms and how to go about avoiding it if you can‚ or treating it if you have it. This pandemic is avoidable through a simple vaccine that can be taken as a shot or as a nasal spray. Overall I find the H1N1 virus to be interesting
