A 12 week old chicken from a young backyard flock is presented for evaluation because of weight loss, decreased appetite, and diarrhea.
The irises in the affected bird are lighter than normal with irregular pupillary margins, and the hen does not have a normal pupillary light reflex (bottom chicken in image). Several other young birds appear to be growing poorly compared to the rest of the flock.
Based on the presumptive diagnosis, how can this problem be prevented going forward?
A - Buy only vaccinated chicks
B - Cull birds from the same genetic line
C - Collect pharyngeal swabs from affected birds; Antibiotic Tx for entire flock based on culture and sensitivity
D - Isolate unaffected animals; Breed from survivors of disease
E - Use only mycoplasma-resistant bloodlines for new additions to flock
A - Buy only vaccinated chicks
A two-year-old, male neutered, sick, indoor/outdoor cat is presented with free fluid in the abdomen.
A sample of fluid is obtained and based on the high viscosity of the peritoneal fluid, feline infectious peritonitis is suspected.
What is a reliable and quick diagnostic test that can be performed on this fluid to differentiate it from effusions caused by other diseases?
A - Rivalta test
B - Coomb’s test
C - Wright’s stain
D - Nissl stain
E - Specific gravity
A - Rivalta test
A 12-year-old Thoroughbred mare just moved to a barn with a stallion. The owner has noted new behavior (see image) and is concerned.
What do these signs demonstrate?
A - Urinary tract infection
B - Pyometra
