Most effective treatment for leptospira infection in growing pigs
Long term use of tetracyclines. Vaccinations are usually only used in the breeding herd where bacterins, containing the appropriate serovar, can reduce the prevalence of infection and leptospirosis-induced abortions. Depopulation or euthanasia is not necessary as in growing pigs the clinical signs are not life threatening (leptospirosis-induced abortions is not a concern). Fluoroquinolone antibiotics are not useful against leptospirosis. Besides tetracycline antibiotics, other effective antibiotics include tylosin, erythromycin, and penicillins.

3 most common causes of colic
- Intussusception
- Cecal dilation (+/- torsion)
- Abomasal volvulus
Synovial gout or articular gout cause and treatment
The disease occurs when uric acid crystallizes in the synovium and causes lameness. Allopurinol is used to decrease uric acid formation. The underlying pathophysiology is not completely understood, but renal disease is found in many affected birds; treatment generally consists of a low-protein diet, allopurinol, and addressing underlying renal disease.
3 MC abx for rodents:
- Enrofloxacin

Carcinoma
These tumors come from epithelial cells including cells of glandular tissues such as salivary glands, mammary glands, and cells lining most tissues including squamous cells or transitional cells. The cytologic appearance is that of COHESIVE CLUSTERS of cells. Here, you can see some of the tight cellular junctions in the cluster which is typical. Cells are often polygonal in shape.
Which organisms is a normal inhabitant of the guttural pouch of a healthy horse?
Streptococcus equi ssp zooepidemicus
** Streptococcus equi ssp. equi can be present when there is guttural pouch empyema. Aspergillus nidulans can be present in cases of guttural pouch mycosis. Salmonella should not be present in the guttural pouch.**

Mast cell tumors in horse: benign or malignant?
Benign.

Round cell tumors
There are 5 round cell tumors and most but not all come from blood cells. They are lymphoma, mast cell tumors, plasma cell tumors, histiocytic tumors, and transmissible venereal tumors. Remember, these are also sometimes also referred to as sarcomas (i.e. lymphosarcoma or histiocytic sarcoma). Cytologically, they appear usually as large populations of cells that are not in defined clusters. The cells have a round shape, often with unique identifiable features such as the purple granules in mast cell tumors.
