Unit 20 – Causes and Spread of Infection 1.1 Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria are microbes with a single cell. There is no nucleus or membrane within bacteria‚ making its structure simpler than that of other organisms. Instead‚ the genetic information is contained in a single loop of DNA. Viruses are microscopic organisms consisting of genetic material surrounded by proteins‚ lipids‚ or glycoprotein coats. Fungi can be multicellular or single celled

and airborne viruses can also spread through close contact with the infected individual or contaminated items. According to the CDC‚ the best way to prevent exposure to is avoid close contact with sick people. If you are sick‚ stay home from work to prevent the disease from spreading.

Unit 265 – Causes and Spread of Infection 1. Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria is something that we need some of‚ it needs a warmth‚ moisture‚ time and food in order to multiply‚ which in the right conditions they multiply quickly. Viruses need a living host in order to survive‚ they don’t respond to antibiotics and new strains of virus are developing all the time. Fungi are moulds and yeasts‚ they need a warm and damp environment to survive‚ much

smaller than bacteria. They are enclosed in a protein coating which makes them more difficult to destroy. The basic unit of Fungi is a hypha which is a hollow tube. The hypha threads spread out over and into the food material making a visible mesh or mycelium. Some fungi form together to create toadstools. They spread by releasing spores into the environment. Fungi can cause diseases in humans in the form of yeasts such as ringworm‚ athlete’s foot and other diseases. A parasite is an organism that
