Oral/Esophageal Disease in Ruminants Flashcards
smooth mouth
ruminants >10 years with no incisors present, increased risk of maintaining weight
if lesions of bovine papular stomatitis virus are advanced, what do you need to rule out
BVDV
calf diphtheria/necrobacillosis/necrotic stomatitis
swelling of larynx and dyspnea/barker calves caused by Fusobacterium necrophoroum
vesicular stomatitis virus
- rhabdoviridae
- indistinguishable from FMD = REPORT CASES TO STATE VET
- cattle, horses, pigs
- summer, fall
- midge vector
- ptalysim from oral ulceration, inappetance, weight loss
sore mouth/orf/contagious ecthyma
- crusting at mucocutaneous jucntion of nose and mouth
- ZOONOTIC
- poxvirus
- sheep and goats, self limitingw ith supportive care
wooden tongue
actinobacillus lignieresii
- gram neg aerobe
- normal oral commensal, injury to mucosa
- pyogranulomatous
- sulfur granules develop within pus
- soft tissue granulomas
- inability to prehend food, esophageal obstruction
txt: sodium iodide, debridement/debulking
lumpy jaw
- actinomyces bovis
- gram + anaerobe
- normal commensal
- infects bones and teeth following injury
- sulfur granules
- firm, painful bony swelling, pyogranulomatous osteomyelitis
- iodine, abx, surgery?
pharyngitis
- trauma, forceful use of balling gun or syringe
- dysphagia, hypersalivation, neuro signs
- aspiration pneumonia as sequelae
esophageal disease
- trauma
- infectious (BVDV, IBR)
- motility dysfunction
salivation, regurg, bloat, rupture, nasal discharge with choke
what isi the most common underlying cause of choke?
megaesophagus
often idiopathic, trauma/tumors, young adults, older adults
salivation, regurg, cervical swelling, weight loss
what causes choke in cattle and camelids?
cattle: indiscriminate grazing
camelids: neuromuscular dysfunction/megaesophagus
calves with megaesophagus often present with
chronic bloat +/- regurgitation
