General - Etiology Flashcards
1
Q
285
Dystrophic calcification (Infracus renis anemicus)
Etiology
A
- Infract is a circulatory disturbance caused by obstruction of tissue’s blood supply
2
Q
225
Hemosiderosis of spleen (Liesegang)
Etiology
A
- Diffuse hemosiderosis occurs during excess intravascular destruction of erythrocytes
- Example: haemolytic infection, parasitic diseases and blood poisoing
3
Q
33
Necrosis hepatis centrolobularis
Etiology
A
- Most common form of zonal necrosis in domestic animals
- Hepatocytes in this area are vulnerable to necrosis due to being farthest away from incoming arterial and portal venous blood (oxygen, essential vitamins)
- Viral infections, tissue hypoxia, passive venous congestion can all lead to centrolobular necrosis of liver
4
Q
180
Necrosis hepatis focalis
Etiology
A
- Caused by bacteria, infectious processs, vascular ischaemia, toxicities, metabolic disorders or neoplastic causes
5
Q
187
Infractus renis anemicus
Etiology
A
- Infract is a circulatory disturbance caused by obstruction of tissue’s blood supply
- Microthrombus leading to widespread ischaemia, necrosis and haemorrhage
6
Q
223
Chronic passive hyperemia of liver
Etiology
A
- Occurs with prolonged impairment of blood outflow from the liver
- Common causes are right-sided heart failure and cirrhosis
7
Q
25
Pleuritis fibrinosa (repair by organisation)
Etiology
A
- Often part of pleural changes in response to various insults, and presentation can vary based on the underlying cause
- Example: infections, pulmonary embolism, trauma, neoplasia etc.
8
Q
148
Fibrosis myocardii
Etiology
A
- This is a substitution of damaged myocardium caused by infract, necrosis, inflammaton etc.
9
Q
255
Bronchopneumonia purulenta
Etiology
A
- Occurs when damage is more severe and large number of neutrophils are present
10
Q
253
Pericarditis fibrinosa
Etiology
A
- Seen most often in in ruminants and swine
- Caused by infections, uremia, trauma, neoplasia, …
- Often part of the broader spectrum of pericardial diseases
11
Q
166
Cirrhosis hepatis
Etiology
A
- Represents the final stage of severe hepatocyte damage after chronic disease processes of liver
12
Q
201
Actinomycosis
Etiology
A
- Causative agent in bovine is Actinomyces bovis
13
Q
263
Pneumonia TBC miliaris - poultry
Etiology
A
- Caused by Mycobacterium avium subsp. avium
14
Q
264
Pneumonia TBC miliaris - poultry with Ziehl-Nielson
Etiology
A
- Caused by Mycobacterium avium subsp. avium
15
Q
219
Adenoma and adenocarcinoma sabaceum
Etiology
A
- Arise from glandular tissues
- Causes are multifactorial (genetics, environment, inflammation, viruses…)
