Pathology
The structural and functional manifestations of disease
General Pathology
The study of the underlying nature of disease processes
Systematic Pathology
The study of the peculiarities of disease affecting each body system
Pathogenesis
The development of disease
Pathophysiology
The physiology of disordered function, or functional sequelae of the morphologic changes
What are the four basic groups of pathogens?
- Physical agents
- Genetic factors
- Chemical agents
- Infectious agents
Aetiology
The science dealing with the causes of disease
Aetiological agent
Pathogen/causative agent involved in a specific disease event
Microbiology
The study of the infectious agents/pathogens
Mycology
The study of the fungal infectious agents
Parasitology
The study of the protozoan and metazoan infectious agnts
Pathogen
Aetiological agent/agent of disease
Pathogenicity
The ability of a pathogenic agent to produce disease in a host
Clinical sign
Objective physical manifestation of a disease detected at clinical examination of an animal
Gross pathology
Changes causing or caused by the disease which are visible to the naked eye
Histopathology
Study of the disease at the microscopic level
Lesion
A structural or functional alteration in a tissue or organ. Can be the result of direct effects of the agent, the host response, or a combination of the two
Manifestations of disease or ‘pathological processes’
- Inflammation and repair
- Circulatory disturbances
- Disorders of growth
- Degeneration
- Accumulation of Pigment and Tissue Deposits
