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.
Infectious disease Microbe that causes the disease Type of microbe
Cold Rhinovirus Virus
Chickenpox Varicella zoster Virus
German measles Rubella Virus
Whooping cough Bordatella pertussis Bacterium
Bubonic plague Yersinia pestis Bacterium
TB (Tuberculosis) Mycobacterium tuberculosis Bacterium
Malaria Plasmodium falciparum Protozoan
Ringworm Trichophyton rubrum Fungus
Athletes’ foot Trichophyton mentagrophytes Fungus
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 flu
Gastrointestinal tract (mouth oral cavity) e.g. Vibrio cholerae which causes cholera
Urogenital tract e.g. Escherichia coli which causes cystitis

>>>Harmful effects of microorganisms: Bacteria: Causes various diseases such as typhoid, diarrhea, and cholera.
>>> Fungi: Causes a large number of diseases in plants and in animals such as rust diseases in plants, fruit rot in apple, red rot in sugar cane and ring worm disease in human beings.
>>>> Algae:Blue-green algae and red tides (produce toxins)
>>> Protozoa: Plasmodium (malaria fever)
>>Protozoa: Causes Amoebic dysentery, pyorrhoea and sleeping sickness etc
>>>>> Algae: Algal boom in water (rapid growth of algae) causes poisonous effect after they die, which in turn results in the death of aquatic organisms.
>>>>Virus: Cause small fox, common cold, influenza, herpes, hepatitis, polio and rabies
>>>Fungi: Causes a large number of diseases in plants and in animals such as rust diseases in plants, fruit rot in apple,
