Pathogencity and Immuneology; Host resistence and the immune response - Essay Example The virulence, resistance and the antigenicity of the microorganism are the most important in my view to determine the spread and severity of the disease that it may cause Virulence of an agent is very important when determining the infection that a certain microorganism is able to cause. Certain agents are highly virulent whereas some of them not virulent because of which they do not cause diseases that can be life threatening. In a community it is necessary that measures are taken by the authorities to ensure that the highly virulent strains do not harm the people in anyway. The resistance of an agent which causes disease is also important in determining its effect on the human beings. If an agent is resistant to environmental conditions then it is possible that it can survive the latest of the antibiotics and this would cause havoc in the human society. Diseases can get severe and life threatening if the resistance of a strain is high. Some of the strains of agents get resistant to antibiotics and adverse environmental conditions because of the continuous exposure to them and hence the authorities should ensure that this practice does not prevail in the community. Lastly the antigenicity of an agent is a factor which helps to determine whether an agent would be able to cause the same disease in the community or not. Some strains have a high antigenicity because of which they can be destroyed immediately while some of the strains have low antigenicity. It is important to determine the antigenicity of an agent so that it can be confirmed that the disease may or may not be caused again. If the antigenicity of an agent is low then the authorities should enhance the passive immunity of the people so that their immune system can fight off the agent. Infectivity is a measure of the ability of an agent to multiply and cause a disease. It is not considered to be important
