What is pathogenicity?

Pathology is the study of tissue, cells and organs in the body as a result of the disease. Pathogenicity is a term applied to a pathogen that is able to cause infectious diseases inside the body. The health problems caused by these microorganisms include both protozoa and bacterial infections and infectious diseases. The pathogenic of the body is often referred to as its virulence. Homeostasis is a process in which the body is able to regulate temperature, metabolism and blood pressure despite the conditions in its external environment. However, if the systems in the body change, the disease may occur. Pathologists study the disease to understand how they work and provide them with treatment. When a pathologist studies a pathogen, he or onasters, he studies cellular and physiological activities that participate in the development of the disease. The process of pathogenesis involves determining what caused the disease, the damage caused and the changes that have occurred since its presence. Some microorganisms are often pathogenic or producing diseases,While others rarely cause the disease. For example, the pathogenicity of opportunistic pathogens is not recurring in people with good health, but can cause infections in people with a low immune system.

diseases such as infections are caused by microorganisms. These microorganisms are pathogens and include bacteria and protozoa. Damage to the body as a result of such pathogens can be straight from the destroyed tissue or may be indirect due to the toxin it produces. Pathogenicity or virulence of pathogens, such as bacteria and protozoa, is measured pathologists and determined by the number of organisms that are needed to appear.

bacteria are involved in many human diseases. Such infections may be smaller, such as an infected eye or ear. They may also be potentially deadly such as tuberculosis, condition that normally affects the lungto the weight. This type of pathogen can enter the body through the skin or holes such as the mouth and nose. The disease is caused by infectious bacteria produces endotoxins and exotoxins that are poisonous, resulting in tissue inflammation.

Another pathogen is a protozoa, a primitive animal that consists of one cell. They are larger than bacteria, but are still microscopic. Most live alone and are able to exclude, absorb food and breathe; However, there are some protozoa that are parasitic and cause disease in humans. Giardiasis is a disease caused by a proto -field infection causing diarrhea.
