Animal testing remains a controversial practice, even in cases where it is used to research treatment for human disease. [34] As in human medical pathology, the practice of veterinary pathology is customarily divided into the two main fields of anatomical and clinical pathology. A tobacco plant infected with the tobacco mosaic virus
Human ewingii ehrlichiosis: The diagnosis can be confirmed by using PCR. A peripheral blood smear can also be examined for intracytoplasmic inclusions called morulae. Doxycycline: No Anaplasma phagocytophilum: Human granulocytic anaplasmosis (HGA) PCR: Doxycycline: No Human metapneumovirus (hMPV) Human metapneumovirus infection No Ehrlichia ...
Diseases in humans that are caused by infectious agents are known as pathogenic diseases. Not all diseases are caused by pathogens, such as black lung from exposure to the pollutant coal dust , genetic disorders like sickle cell disease , and autoimmune diseases like lupus .
Airborne disease, a disease that spreads through the air. Contagious disease, a subset of infectious diseases. Cryptogenic disease, a disease whose cause is currently unknown. Disseminated disease, a disease that is spread throughout the body. Environmental disease; Lifestyle disease, a disease caused largely by lifestyle choices.
Pathogenic bacteria are bacteria that can cause disease. [1] This article focuses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and are often beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. [2]
A human pathogen is a pathogen (microbe or microorganism such as a virus, bacterium, prion, or fungus) that causes disease in humans. The human physiological defense against common pathogens (such as Pneumocystis ) is mainly the responsibility of the immune system with help by some of the body's normal microbiota .
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
Viral pathogenesis is the study of the process and mechanisms by which viruses cause diseases in their target hosts, often at the cellular or molecular level. It is a specialized field of study in virology. [1] Pathogenesis is a qualitative description of the process by which an initial infection causes disease. [2]
