Microbes and disease

A few harmful microbes, for example less than 1% of bacteria, can invade our body (the host) and make us ill. Microbes cause infectious diseases such as flu and measles.

There is also strong evidence that microbes may contribute to many non–infectious chronic diseases such as some forms of cancer and coronary heart disease. Different diseases are caused by different types of micro-organisms. Microbes that cause disease are called pathogens.

It is important to remember that:

A pathogen is a micro-organism that has the potential to cause disease.An infection is the invasion and multiplication of pathogenic microbes in an individual or population.Disease is when the infection causes damage to the individual’s vital functions or systems.An infection does not always result in disease!

To cause an infection, microbes must enter our bodies. The site at which they enter is known as the portal of entry.

Microbes can enter the body through the four sites listed below:

Respiratory tract (mouth and nose) e.g. influenza virus which causes the fluGastrointestinal tract (mouth oral cavity) e.g. Vibrio cholerae which causes choleraUrogenital tract e.g. Escherichia coli which causes cystitisBreaks in the skin surface e.g. Clostridium tetaniwhich causes tetanus

To make us ill microbes have to:

reach their target site in the bodyattach to the target site they are trying to infect so that they are not dislodgedmultiply rapidlyobtain their nutrients from the hostavoid and survive attack by the host’s immune system
