Good empirical antibiotics used for periodontal pathogens?
Metronidazole, clavamox, clindamycin
Normal lymph nodes should still be aspirated in cases of oral melanoma or squamous cell carcinoma. T/F?
True - tumors have very high metastatic rate
Difference in muscle layering of esophagus in dogs and cats?

Breeds predisposed to cricopharyngeal dysphagia?
Springer and Cocker Spaniels
Levels of CK with focal or chronic myopathies?
Can range from normal to high
Benefits of swallow study in sternal vs lateral?
cervical esophageal transit is significantly delayed when dogs are in lateral recumbency. Swallow studies on dogs in sternal recumbency are significantly more likely to result in generation of primary peristaltic waves for both liquid and kibble boluses.
Most common cause of high grade esophagitis and stricture formation in dogs?

Which short chain fatty acid is major source of energy for colonocytes?

What contributes to gastric acid secretion?
Binding of histamine, gastrin, acetylcholine to parietal cells
Causes for elevated gastrin other than gastrinoma?
Using PPIs, liver or renal dysfunction
An upper GI obstruction will cause what pH change in the urine?
