Cellular pathology
Pathology based on microscopic changes in body cells produced by disease. Termed as cytopathology, this division of cytology focuses on how diseases impact cells.
-
Anatomic pathology
The field of pathology that deals with structural changes in disease.
-
Pathognomy
Diagnosing the cause of an illness after careful study of the signs and symptoms of a disease.
-
Pathogen reduced plasma
Plasma that has been treated with detergents, methylene blue, or ultraviolet energy in order to reduce the likelihood that it will transmit infection during transfusion.
-
Bacterial pathogenesis
The development of a bacterial disease. There are three stages: entry and colonization in the host, bacterial invasion and reproduction with the production of toxic substances, and the response of the host. The mere presence of an organism in the body does not necessarily mean that disease will follow. This progression of the infection will…
-
Pathogen-associated molecular patterns
Any of several molecular sequences associated with or found in many different disease-causing microorganisms to which the innate immune system reacts without initiating an antigen-antibody response.
-
Opportunistic pathogen
A microorganism that is usually harmless but may become pathogenic in certain circumstances, e.g., when it is introduced into a part of the body where it normally does not reside or when it infects an immunocompromised host.
-
Bloodborne pathogen
A pathogen present in blood that can be transmitted to an individual who is exposed to the blood or body fluids of an infected individual. Three common bloodborne pathogens are hepatitis C, hepatitis B, and human immunodeficiency virus 1 (HIV-1). Disease-causing microorganisms carried in the body by blood or body fluids, such as hepatitis and…
