At what stage do larvae become arrested in the host

L4

At what age are larvae infective to the host

L3

What is the approximate pre-patent period of most GI strongyles when the weather conditions are optimal?

2-4 weeks

Where in the GI tract are trichostonglyes found

Abomasum and SI

Which anthelmintic groups are commonly called white drenches

Benzimizaoles

Which anthelmintic groups are commonly called yellow drenches

Imidazothiazoles (levamisole)

Which anthelmintic groups are commonly called clear drenches

Macrocyclic lactones

What parasite do you associate with tenesmus

Coccidia

What will you see on chem with trichuris suis

Hypoalbuminemia (PLE)

What triggers the hatching of nematodirus

Increase in temp more than 10 degrees celcius in spring

What should you FERT be if your drench was effective

At least 95%

In a goat with persistent worm infestation what trace element def is most likely to be the underlying problem? What about cattle?

Cobalt

Copper

How does ostertagia ostertagia lead to elevated pepsinogen

Because the damaged gastric glands leak pepsinogen backwards into the bloodstream rather than secreting it forward blood serum pepsinogen levels spike dramatically as a diagnostic marker

What marcocyclic lactone do you need for ostertagia ostertagia

Effective against inhibited fourth stage ostertagia ostertagia larvae

Ivermectin, doramectin, moxidectin, eprinomectin

Which factors contribute to luminal distention in complete intestinal obstruction?

Gas accumulation

Fluid accumulation related to hypersecretion in the gastrointestinal tract

Fluid accumulation related to reduced absorption in the gastrointestinal tract

Experimental studies of dogs with intestinal obstruction showed selective intestinal mucosal ischemia when intraluminal pressure was

Higher than 40 mm Hg.

Fluid and electrolyte losses in intestinal obstruction may be the result of

Vomiting.

Diarrhea.

Fuid sequestration in the intestinal lumen.

Vomiting in a dog with distal intestinal obstruction may result in

Metabolic acidosis.

Which antibiotic is recommended for prophylactic use in surgery on the large intestine?

Cefoxitin

Which characteristic is not used for assessment of intestinal viability?

Wall thickness

_______ may increase the possibility of dehiscence after enterotomy closure.

Excessive mucosal eversion

Cats with linear FB ingestion may be managed conservatively if they

Present soon after ingestion and have no signs of peritonitis.

In patients with linear FBs, intestinal resection and anastomosis are recommended for treatment of

Multiple perforations and subsequent peritonitis.

Intestinal fibrosis and permanent plication.

Extensive intestinal wall compromise.

What is enteroplication and what is a complication that can be seen with it

Tacking of the intestine to itself to prevent intussuception

Can cause an obstruction if there are tight turns in the intestine

What can be said about the cleanliness for GI surgeyr

Clean contaminated or contaminated depending on the amount of spillage
