1) Griseofulvin
2) Veratrum californicum
Describe the pathogenesis of ingesting Veratrum californicum
plant contains steroidal alkaloids (jervine & cyclopamine) that inhibit hedgehog signaling pathway during development
Name the potential outcome if a sheep eats Veratrum californicum on:
1) Day 14 of gestation
2) Days 17-19 of gestation
3) Days 28-31 of gestation
1) congenital deformities of head
2) tracheal deformations
3) shortened metatarsal and metacarpal bones
Describe the difference between brachygnathia superior and inferior
Superior–short maxilla with normal mandible (bulldog)
Inferior–short mandible with normal maxilla (parrot mouth)
What term is use to describe:
1) elongated mandibles
2) absence of a lower jaw
1) prognathia
2) agnathia
Name the term that describes inflammation in the following areas:
1) lips
2) oral mucosa
3) tongue
4) gums
5) pharynx
6) tonsils
1) chelitis
2) stomatitis
3) glossitis
4) gingivitis
5) pharyngitis
6) tonsillitis
A parapox viral disease of cattle that causes papule formation in the oral cavity, nares, and muzzle; ZOONOTIC!
Bovine papular stomatitis
This is a zoonotic disease of sheep and goats where lesions appear on the corners of the mouth, udders, and around coronary bands
Contagious ecthyma (orf)
A vesicular disease not caused by a virus?
Pemphigus vulgaris
This is an oral disease of cats where proliferative lesions form on the glossopalatine arches
Feline plasma cell gingivitis (Feling lymphoplasmacytic stomatitis)
This disease, though more common in cats, can affect siberian huskies and cause ulcerative lesions to form at the mucocutaneous junctions
Oral eosinophilic granuloma complex
A dog with severe dental plaque may be at risk for this disease?
Chronic ulcerative paradental stomatitis
The causative agent of oral necrobacillosis (calf diphtheria)?
Fusobacterium necrophorum
also causes foot rot in ruminants
This bacteria can invade oral wounds and cause granulomatous inflammation and fibrosis in the deep tissues of the tongue
Actinobacillus lignieresii
wooden tongue
Name disease and causative agent:
chronic granulomatous inflammation of the mandible; can have draining tracts with “sulfur granules”
Lumpy Jaw
Actinomyces bovis
T/F: the causative agent of thrush is a common oral inhabitant
True (Candida albicans)
Name two drugs which are known to induce gingival hyperplasia. Tx?
Amlodipine & cyclosporine
No need to treat; will resolve when drugs are stopped
T/F: Thrush is NOT a primary disease
True! (secondary to debility or long-term antibiotic therapy)
Describe the differences in squamous cell carcinoma behavior in dogs vs. cats
Dogs–commonly affects the tonsils and metastasizes
Cats–usually on the tongue and metastasis is more rare
Which oral neoplasm appears aggressive from a histological standpoint but doesn’t behave aggressive and does not metastasize
Oral (extramedullary) plasmacytoma
Name the two subclassifications of epulides; Which is more locally invasive and can lead to bone destruction?
1) Fibromatous epulis
2) Acanthomatous epuli (locally invasive)
Define sialodenitis;
Name 4 things that can cause it
inflammation of salivary glands;
1) Rabies
2) distemper (dogs)
3) Strangles (horses)
4) Vitamin A deficiency
