An agent's capacity to produce disease depends upon:
An agent's capacity to produce disease depends upon the dose and the virulence of the agent.
Bear in mind that several agents may be involved - often one agent debilitates, allowing others to exert a greater effect that normal within the body. The presence of an agent does not necessarily mean it is the cause of the disease! On occasions, a pathogenic agent may be absent from the tissues, due to either clinical therapy or the action of the host defence systems
