GI 1 part 2 Flashcards
Vesicular stomatides - name them
foot & mouth disease
vesicular stomatitis
vesicular exanthema of swine
swine vesicular disease
why are they called the big 4?
-all are viruses
-can look identical grossly & histologically
-all have high morbidity but low mortality
-ALMOST ALL ARE REPORTABLE (vesicular exanthema of swine is the exception)
-trade implications and production limiting
what is a vesicle?
accumulation of serous fluid usually between epithelium and lamina propria
vesicles are usually ____-lived and rupture to form __________
short, ulcers
vesicles in cats & dogs - think
immune mediated disease - calicivirus the exception
vesicles in food animals - rule out
important viral causes
foot and mouth disease caused by
foot and mouth disease virus
foot and mouth disease (FMD) affects
all cloven hooved animals (sheep, goats, cattle)
which common domestic species is not affected by FMD
horses
which unusual wildlife species is affected by FMD
asiatic black bears
FMD clinical signs
high morbidity, low mortality
mortality only in neonates
myocarditis
production losses
vesicle formation in and around the mouth, on the feet, mammary glands
where do vesicles appear FMD
vesicle formation in and around the mouth, on the feet, mammary glands
areas prone to trauma
can get hoof sloughing
Vesicular stomatitis caused by
vesicular stomatitis virus
vesicular stomatitis prevalence in NA
sporadic in NA, enzootic in central & SA
Vesicular stomatitis - who is affected
horses, cattle, and pigs (plus wildlife including white tailed deer, raccoons, feral swine, rodents, humans)
zoonotic
which food animal species are not affected by vesicular stomatitis
sheep & goats
vesicular stomatitis clinical signs
vesicles in oral cavity > feet, mammary glands & animals may froth at the mouth
vesicular exanthema of swine is caused by
vesicular exanthema of swine virus
vesicular exanthema of swine occurs in
pigs (duh)
vesicular exanthema of swine - what other species does it still exist in
California sea lions - potential for transmission to pigs if fed uncooked ocean origin fish
swine vesicular disease caused by
swine vesicular disease virus
swine vesicular disease affects
pigs
swine vesicular disease clinical signs
vesicles on the coronary bands and heels > oral cavity and mammary glands
can cause nonsuppurative meningioencephalomyelitis
FMD family of virus
picornavirus
Vesicular stomatitis virus family
rhabdovirus
vesicular exanthema of swine virus family
calicivirus
swine vesicular disease virus family
enterovirus
FMD distribution
enzootic in africa, asia, Europe, South America
vesicular stomatitis distribution
endemic in south and Central America, sporadic in USA
vesicular exanthema of swine distribution
sea lions from CA to Alaska
swine vesicular disease distribution
italy, hong king, UK, Europe, Asia
what is an important mimic of the big 4
Seneca valley virus
vesicular stomatitides small animals causal agent
feline calicivirus
bovine papular stomatitis caused by
bovine papular stomatitis virus
paradox virus similar to papular viruses - also causes proliferation
bovine papular stomatitis affects
calves
bovine papular stomatitis gross lesions
targets hard and soft palate and around the teeth - scalloping around teeth
centre becomes elevated over time and tan with a red rim (targetoid)
bovine papular stomatitis histologic lesions
epidermal hyperplasia with ballooning degeneration
is bovine papular stomatitis zoonotic
yes
orf is also called
contagious ecthyma, contagious pustular dermatitis
orf caused by
a parapox virus
which species does orf affect
sheep and goats & muskox
is orf zoonotic
yeah boiiiii
gross lesions orf
proliferative scabby lesions on the lips, face, udder, and feet which can extend into the oral cavity
other causes of ulcerative stomatitis in bovines
bovine viral diarrhea virus
malignant catarrhal fever
rinderpest - eradicated in 2011
ulcerative stomatitis can be associated with
uremia
ulcerative stomatitis in cats lesion appearance
dirty grey brown ulcers on the gums, lateral tongue, inner lips, and cheeks
salivary glands - what kind of problems do they normally have
functional problems NOT infectious
inflammation of salivary gland
sialadenitis
ranula
partial or complete obstruction of salivary duct leading to duct dilation and results in a smooth round fluctuant mass on floor of mouth
sialocele
accumulation of salivary secretions in soft tissue of the mouth or neck
result of trauma and rupture of a duct
not lined by duct epithelium
sialolith
concretions within the salivary gland
reactive and hyperplastic lesions are familial in
boxers
benign tumours - name one
oral papillomatosis aka warts
oral papillomatosis more common in
young animals & usually spontaneously regress
fibromatous epulis of periodontal ligament origin (FEPLO) is also called
POF (peripheral odontogenic fibroma) or epulis
FEPLO or POF is most common in
dogs
Canine acanthomatous ameloblastoma (CAA) is unique to
dogs - is common odontogenic tumour of dogs, coming from ameloblasts
is canine acanthomatous ameloblastoma metastatic
it does not metastasize but is locally aggressive and invades bone
non-odontogenic tumours of the oral cavity - 3 most common in dogs
- melanoma
- squamous cell carcinoma
- fibrosarcoma (FSC)
non-odontogenic tumours of the oral cavity - 4 most common in cats
- SCC (60-70% of all oral tumours
- FSC (20%)
- Lymphoma
- Melanoma
are oral cancers a big deal in cats?
yes, very poor prognosis
SCC is the _____ common oral malignancy of cats, _______ common oral tumour in dogs
most, second most
are SCC locally invasive?
yes - invasive into bone
gross appearance of SCC
irregular, nodular, frequently ulcerated
malignant melanoma histology
variable pigmentation - extremely variable appearance (histo + grossly), risk of misdiagnosis
fibrosarcomas (FSC) are most common in who
young, large breed dogs, especially golden retrievers
FSC are frequently referred to as
high-low fibrosarcoma
