CU254 Aims Causes and Spread of Infection This unit is to enable the learner to understand the causes of infection and common illnesses that may result as a consequence. To understand the difference between both infection and colonisation and pathogenic and non pathogenic organisms‚ the areas of infection and the types caused by different organisms. In addition‚ the learner will understand the methods of transmission‚ the conditions needed for organisms to grow‚ the ways infection enter the

1/03/13 Introduction to Pharmacology II Targets of Drug Action March 5 How do drugs work? | Nearly all drugs act by interfering or inhibiting natural processes which are required for normal physiological function but which may have been disrupted by disease. | Paul Ehrlich 1845-1915 | Observed that certain chemicals or drugs bound in a selective manner to some but not all cells. He recognised that the cells must have chemical recognition sites for these drugs. The concept of a “receptor”

What are bacteria? Bacteria are very different from viruses. First of all‚ bacteria are much larger in size. The largest virus is only as big as the very smallest bacterium (singular for bacteria). But bacteria are still microscopic and cannot be seen with the naked eye. They are so small that the sizes of bacteria are measured in micrometers (10‚000 micrometers = 1 centimeter). By comparison‚ the head of a pin is about 1000 micrometers wide. Though more complex than a virus‚ the structure of a
