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

called the Sarcodines and the Flagellates called the Mastigotes are sometimes linked into one group called the Sarcomastigotes because of similar features. The Ciliates are about as complicated as single cells can be. The Sporozoans tend to be tiny parasites‚ often living inside other cells‚ but are also pretty complicated.

Unit 20 – Causes and Spread of Infection 1.1 Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria‚ fungi and parasites are all considered as ‘living’ things‚. Bacteria are single celled microorganisms that can only been seen through a microscope‚ they collect their nutrition from their surrounding and unlike viruses‚ they do not need a living host to reproduce. Viruses are difficult to destroy because they are enclosed in a protein coating. Viruses are disease-producing

erythrocytes are being destroyed by a parasite that infects them. What is the process of blood cell formation that replenishes lost cells? Erythropoesis is the process of blood cell formation. Case Story‚ Question 4 Why would Ed’s RBCs be a good host for a parasitic protozoan? RBC’s are a good host because they allow the protozoan to grow and multiply. When the RBC’s are unable to withhold all of the parasites‚ they lyse and explode‚ releasing the parasites and infecting more and more RBC’s..
