2. Enanthemas; different basic forms of stomatitis. Bovine papular stomatitis

Question 1

enanthema

Answer 1

local alteration on the mucous membrane (eruption on mucosal surface)

Question 2

classification of enanthema

Answer 2

Erythema, Papula, Vesicle, Pustule, Erosion, Ulcer, Necrosis

Question 3

result of enanthema

Answer 3

anorexia due to painful mastication, common with hypersalivation

Question 4

Roseola, erythema result in

Answer 4

– local hyperemia, slight inflammation, intense red color of mm, extended blood vessels

Question 5

Papula results in

Answer 5

proliferation of cells (str. germinativum), not moveable
o Bovine Papular Stomatitis (Pox, Parapox)

Question 6

Aphta results in

Answer 6

pseudomembrane formation

Question 7

causes of vessicles

Answer 7

FMD (Picorna, Aptho) – zoonosis.
Vesicular stomatitis (Rhabdo, Vesiculo) – zoonosis.
Swine vesicular disease (SVD) (Picorna, Entero).
Vesicular exanthema swine (Calici, Vesi)

Question 8

consequences of vessicles

Answer 8

Ballooning (hydropic degeneration): water accumulation around nuclei, apoptosis, spongiosis =
intercellular edema, reticulating degeneration. Cellular necrosis.

Question 9

Causes of erosion

Answer 9

mechanical trauma, epithelial degeneration, necrosis, vesicle rupture (serous or purulent),
papula, aphta

Question 10

causes of ulceration

Answer 10

Stachybotriotoxicosis, BVD

Question 11

Stomatitis

Answer 11

Inflammatory process of mm of the oral cavity

Question 12

Bacterial stomatitis

Answer 12

Fusobacterium necrophorum
Actinobacillus lignieresi
Actinomyces bovis

Question 13

Viral stomatitis

Answer 13

FMD (Picorna, Aptho),
Vesicular stomatitis (Rhabdo, Vesiculo), Papular stomatitis (Pox, Parapox),
Swine vesicular disease, SVD (Picorna, Entero),
Vesicular exanthema of swine (Calici, Vesi).

Question 14

causative agent of bovine papular stomatitis

Answer 14

Poxviridae →Parapoxvirus

Question 15

Milder symptoms of bovine papular stomatitis

Answer 15

papule formation/raised papules (on hard palate, lips, muzzle + tongue), salivation, fever

Question 16

Histopath of bovine papular stomatitis

Answer 16

o Ballooning degeneration in the lower layer of the squamous epithelium.
o Hyperaemia, oedema, cellular infiltration
o Proliferation of the epithelial cell, cytoplasmic inclusion bodies.
o Cytoplasmic inclustion bodies can be observed
o Superficial necrosis, desquamation, erosion
o Healing

Question 17

lesions of bovine papular stomatitis

Answer 17

Hyperemia
edema
cellular infiltration
papules on nares, muzzle, gingiva, palate & tongue
superficial necrosis, desquamation, erosion.

Question 18

consequence of bovine papular stomatitis-

Answer 18

might lead to spontaneous healing

Question 19

Differential diagnosis of bovine papular stomatitis

Answer 19

FMD: vesicular + erosive lesions, high fever, high morbidity + mortality among young stock.
o VS (Vesicular Stomatitis): Macules, vesicles, erosions appear in the mm of the mouth, skin of teats,
feet.
o BVD: Shallow erosions on the entrance of the nostrils, mouth, pharynx, larynx,esophagus, rumen,
omasum, abomasum, caecum and less frequently in Peyer’s patches in the small intestine
o Rinderpest
