MLT 1 Dr. Kim Shahi and Dr. Heidi Atkinson September 3‚2013 Experiment 11: Fomite Transmission Elements Necessary to Spread Infection There are three elements necessary for the spread of infection. First there has to be a source of an infective organism. This source can be endogenous or exogenous. Endogenous sources of infection reside on or in the host’s body. In contrast exogenous sources arise from outside. Second there has to be a mode of transmission. Described in

Microbiologist Microbiologists are scientists that focus on organisms that can sometimes cause infection. They study bacteria‚ fungi and viruses. They try and diagnose infections so that they can identify and characterise organisms. They have a big effect on the world as without them‚ we would have no cure for illnesses. A skill that a microbiologist requires is to be able to create a sample using one hand as this is more efficient and also vastly more productive than performing the procedure without
