false
severe
This degree of inflammation is characterized by Hyperemia – Slight edema – Hemorrhage, Few leucocytes, and present with shock or sudden death as clinical signs
peracute
This degree of inflammation starts within 4-6 hrs, Active hyperemia • Edema (due to endothelial damage‐lymphatics and small blood vessels) • Occasional fibrin thrombi within vessels, eucocyte infiltration is variable (dependent upon TIME), in general neutrophils usually predominate, but sometimes mononuclear cells (lymphocytes and plasma cells) can also be present
acute inflamation
reactive inflammation of lymph node(s) occurs in acute, subacute and chronic inflammation
lymphadenitis
inflammation of lymphatic vessel(s)
lymphangitis
Fibrosis and neovascularization are not features of this degree of inflammation
subacute
Origin of this degree of inflammation It may follow an acute inflammatory phase. – It may develop as an insidious, low‐grade, subclinical process without history of a prior acute episode.
chronic
Give the Mdx of this chronic inflammatory process
Multifocal ulcerative colitis
The lymph vessels of this goat are chronically inflammed (____) in what dz?
lymphangitis
John’s dz
This is what type of distribution of the yellow (interpreted as pus) esion in the deer brain
focal
this focal keratitis is inflammation of the
cornea
Intersititial pneumonia is an example of what type of distrubution of inflammation
diffuse
Cranioventral aspects of the lungs are involved (dark red) while the dorsal portions are spared
locally extensive
What type of exudate is found in this bronchopneumonia in a dog
suppurative
True or false
severe suppurative pyelonephritis in a dog
true
true or false
Pyometras are a serous exudate inflammation
false
suppurative
an abscess is a localized form of
suppurative inflammation
this chronic osteomylitis is a ___ inflammation
suppurative
This ____ is degranulating enxt to a helminth in TEM
eosinophil
severe injury to endothelium and basement membranes results in leakage of plasma proteins including fibrinogen, which polymerizes perivascularly as fibrin.
fibrinous exudate
This is what type of exudate
fibrinous
fibronous enteritis
Yellow friable and easy to peel off
fibrinous exudate
This term is used to classify an inflammatory process in which neutrophils and fibrin are abundant
Fibrinopurulent exudate
Fibrinopurulent exudate
true or false
Presence of a fibrinous exudate involves an chronic process. In contrast, fibrosis is a acute process.
false
Presence of a fibrinous exudate involves an acute process. In contrast, fibrosis is a chronic process.
acute process surface covered by friable material and highly homeogenous eosinophillic material (arrows pointing to basophillic bateria)
Fibrinous pleuritis in a horse
Which is fribrinous and which is fibrous?
L) fibrinous
R) fibrous
true or false
Fibrous inflammation
false
fibrous CT adhesions
true or false
fibrinous inflammation
true
Equine heart. Epicardial surface covered by fibrin
fibrinous inflammation
Bovine liver Cut surface demonstrating thickenning of bile ducts Chronic ___
chronic fibrosing cholangitis
this exudate is Yellow, straw‐like colour, fluid commonly seen in very early stages of many kinds of inflammatory responses • Ulceration will follow the rupture of a vesicle.
serous
What type of inflammatory response is this?
granulomatous
Macrophages are clustered in a characteristic elliptical formation around the causative etiologic agent, or around a central necrotic area, or simply as organized nodules. • Large cells with abundant cytoplasm, referred to as “epithelioid cells, and “multinucleated giant cells” are also commonly present in this type of inflammatory response
granuloma
Diffuse granulomatous inflammation seen in what dz?
john’s dz
what type of exudate is here
hemorrhagic
What type of inflammation is this?
becrotizing inflammation
SEGMENTAL HEMORRHAGIC ENTERITIS is an ___ process
acute
Diffuse severe ____ _____ affects the mucosal and serosal layers of the bladder
hemorrhagic cystitis
?
Mucoid enteritis.
inflammatory exudate is composed of mucus and pus (neutrophils and cell debris)
MUCOPURULENT
MUCOPURULENT is also called
catarrhal
Etiology: Turkey pox virus Severe ___ dermatitis.
multifocal to coalescent
Pig ileum
Fibrino‐necrotizing enteritis
Resolution: involves neutralization of the chemical mediators, with subsequent return of normal vascular permeability, cessation of leucocytic infiltration and finally removal of edema fluid, leucocytes, foreign agents and necrotic debris. This picture resolved by forming a ___
scar
This is an ____
abscess
This is a slide of an ___
abscess
This is an example of a chronic process ___
hepatic granuloma
What is the distribution of these granulomas?
multifocal
example of ___ inflammation
Fibrinous pneumonia
Fibrous= fibrosis= fibrous connective tissue= formed by fibroblasts and collagen= chronic
What is the arrow pointing to?
Multinucleated Giant Cells are formed by coalescence and fusion of epithelioid cells. This fusion is induced by cytokines.
True or false
this is a picture of multiple cells lined up next to each other
false
one giant cell
Is this acute or chronic?
chronic
what type of inflammation
granulomatous
What is secondary to granulomatous inflammation
fibrosis
