Pathology of Disease Flashcards
The study of the course and development of structural and functional changes in the body caused by disease
Pathology
Abnormality of structure or function with recognizable clinical signs
Disease
Evaluation of blood, urine, fluids, and feces
Lab tests, hematology, and serology
Clinical Pathology
Study of changes in tissues that are visible with the unaided eye
(PE/necropsy)
Gross pathology
Study of changes in tissues that are microscopic
Biopsy - impression smear, FNA, punch biopsy
Histopathology
The science of dealing with various factors that determine the frequencies and distribution of an infectious disease
Epidemiology
Refers to a disease that occurs naturally but in small numbers within a local area
Endemic, Enzootic
An unusually high prevalence of a disease present in a region, which may be rapidly spreading
Epidemic, epizootic
The ratio of the number of sick animals to the total number of animals involved
Morbidity
The ratio of the number of dead animals to the total number of animals involved
Mortality
An infection acquired during hospitalization
Nosocomial
A characteristic of a disease that distinguishes it from other disease
pathognomonic
The study/detection of antibodies or antigen in the blood/stream
Serology
The disease producing power of a microorganism
virulence
Incomplete, imperfect, or lack of development
Agenesis, aplasia
Underdevelopment of a tissue, organ, or limb
hypoplasia
An abnormal development of a tissue or organ
dysplasia
Reduction in size of a previously normal sized organ
atrophy
A moderate area of blood accumulation (bleeding) usually seen under the skin (a bruise)
Ecchymotic hemorrhage
Tiny pin-point hemorrhages
Petechia
Inflammation of blood or lymph vessels
vasculitis
A foreign body within the blood stream
emboli
A region of dead tissue due to a complete interference with blood flow
infarct
Invasion and multiplication of organisms in the body
infection
Period when disease develops by multiplication of an infectious agent within a host
incubation
When a disease is present without clinical signs
sub-clinical
Time of mild symptoms
Prodromal period
Signs of disease are present
clinical
partial or complete loss of hair
alopecia
An abnormal accumulation of serous (watery) fluid in the abdominal cavity
ascites
Cheese-like exudates
caseous
Pertaining to an accumulation of air within tissues
emphysematous
Loss of surface tissue due to inflammation or trauma
erosion, ulceration
A discharge from the body
exudate
Having a foul odor
fetid
Excessive collection of serous fluid in the thoracic cavity
hydrothorax
Fatty accumulation within a tissue or organ resulting in interference of function
lipidosis
An alternation from normal in structure or function resulting from injury or disease
lesion
An enlargement of the lymph nodes
Lymphadenopathy
Having a smaller than normal brain
Microencephaly
Creamy exudates consisting of mucus and cells
mucopurulent
Refers to dead cells or tissue in contact with living cells
necrotic
Affecting many joints
polyarticular
Pus
purulent
Completes systemic involvement of an infectious disease, when microorganism and its products are throughout the bloodstream
septicemic
enlargement of the spleen
splenomegaly
a superficial cavity filled with fluid elevated above the surface of the tissue or organ (blister)
vesicle
the internal organs of the trunk of the body
viscera
