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. A BACTERIAL CELL Illustration courtesy of Wikipedia. A Virus (from the Latin noun virus‚ meaning toxic or poison) is a sub-microscopic

random mutations that are beneficial are conserved in the species‚ previous exposure to antibiotics‚ and some bacteria are naturally transformable; meaning they can absorb the genomic material of other bacteria into their own. 4. What is a fomite? A fomite is an inanimate object (as a dish‚ toy‚ book‚ doorknob‚ or clothing) that may be contaminated with infectious organisms and serve in their

There are 2 ways that the fomites can be transmitted. These include direct and indirect transmission. Direct transmission occurs when there is physical contact between an infected person and a susceptible person. Indirect contact transmission occurs when there is no direct human-to-human contact. Contact occurs from a reservoir to contaminated surfaces or objects‚ or to vectors such as insects or animals. Direct contact infections spread when microorganisms pass from the infected person to the healthy

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

Data transmission‚ digital transmission‚ or digital communications is the physical transfer of data (a digital bit stream) over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires‚ optical fibres‚ wireless communication channels‚ and storage media. The data are represented as an electromagnetic signal‚ such as an electrical voltage‚ radiowave‚ microwave‚ or infrared signal. Data representation can be divided into two categories: Digital
