Diseases can cause a number of symptoms to any part of the body. Communicable diseases are ones that are spread by an infection when you come in contact with someone who has it. Noninfectious diseases do not spread and they are generally caused from genetics, environmental factors or deficiencies in nutrition.
Asthma, diabetes, stroke, cancer, chronic obstructed pulmonary disease and cystic fibrosis are examples of non-infectious diseases, which are commonly known as non-communicable diseases or NCDs.
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.

Types of Microbes. The microorganisms, or microbes, that can cause disease come in different forms. Viruses and bacteria are probably the most familiar because we hear so much about them. But fungi, protozoa, and helminths are also big players in the story of infectious disease.
Asthma is a non-infectious disease also known as a lung disease. It inflames the airways and the air passages to the lungs become narrowed. As a result of the airways becoming narrowed there is not enough room for the the air to pass through therefore the victim has difficulty breathing.
Not all diseases can be spread from one person to another. In this lesson, we'll learn about non-infectious diseases: what they are, some examples of them, and how they are treated.
Types of Microbial Diseases. Microbial diseases may be caused by: Bacteria; There are millions of different bacteria that exist for many different reasons, some good and some bad. For instance, there are good bacteria inside of your body that helps your immune system to function properly, such as by helping you to digest your food.
Harmful bacteria can affect almost any area of the body. Other types of bacterial infections include: Bacterial meningitis is a severe infection of the meninges, the lining of the brain. Otitis media is the official name for an infection or inflammation of the middle ear.
