Diabetes mellitus
- The two common causes of infection in dogs with diabetes are urinary tract infections and dental disease.
- Urinary tract infections are common in dogs with diabetes for several reasons.
- First, diabetic animals have more dilute urine than healthy animals. This allows for bacterial growth since the chemicals present in concentrated urine, which normally kill bacteria, are diluted.
- Second, the urine of diabetic animals contains sugar, which attracts bacteria and helps facilitate bacterial growth.
- Finally, dogs with diabetes will often have distended bladders because they drink more, and this allows bacteria to be in contact with the bladder for longer than it should

- To differentiate pituitary dependent hyperadrenocorticism from adrenal tumor, what test should you use?
- ACTH stim (measure cortisol)
- Urine creatinine:cortisol ratio
- Low dose Dex suppression
- High dose Dex suppression
High Dose Dex Suppression
- With pituitary origin Cushing’s disease, we normally see a markedly increased cortisol level following the synthetic ACTH injection. This exaggerated response occurs because the adrenal glands have been over-stimulated with naturally occurring ACTH secreted by the diseased pituitary (pituitary origin Cushing’s disease).
- These adrenal glands are therefore highly responsive to stimulation by the synthetic ACTH. With adrenal origin Cushing’s disease, an exaggerated cortisol level after the synthetic ACTH injection may also be seen.
- In rare instances with pituitary origin Cushing’s disease, the negative feedback loop is more resistant to the effects of dexamethasone. A higher dosage of this synthetic cortisol may be required to overcome this resistance and demonstrate the negative feedback mechanism. If there is a reduction in cortisol levels at either 4 and/or 8 hours after the higher dose of dexamethasone, then we have diagnosed pituitary origin Cushing’s disease. If the levels do not budge from the high values of the pre-injection sample, then the diagnosis is adrenal origin Cushing’s disease.
- A woman brings a litter of Dalmatian puppies to your clinic. How do you check for deafness?
BAER test
- Brainstem auditory evoked response (BAER) testing is an electro-diagnostic test used to evaluate the hearing of dogs, cats, and other domestic animals
1. Early diagnosis of hearing loss secondary to cochlear agenesis/degeneration.
2. Assessment of brainstem (caudal part of the brain) function.

- Feed more beet pulp
- Decrease alfalfa, increase timothy hay, put out to pasture
Decrease alfalfa, increase timothy hay, put out to pasture
- In general, alfalfa and brome hays typically contain higher levels of potassium than what an HYPP-affected horse would be able to handle and should be fed sparingly, if at all.
- Horses with HYPP (Hyperkalemic periodic paralysis) should be allowed consistent access to hay that has low or moderate potassium levels such as Timothy or Bermuda grass hays

Euthanize immediately (fatal white foal syndrome)
- Lethal white overo (LWO) syndrome, also known as ileocolonic aganglionosis or aganglionic megacolon, is an autosomal recessive inherited disease primarily reported in Paint horses.
- Horses with a particular white spotting pattern known as frame overo can produce affected offspring
- Affected foals are all white and are born with an underdeveloped intestinal tract. They cannot move food through their intestinal tract properly and cannot defecate, leading to colic.
- In a horse with exercise intolerance, which of the following is associated with increasing age?
- Allergic bronchitis
- Bacterial pneumonia
- Selenium/vitamin E deficiency
- VSD
Allergic bronchitis
- Allergic bronchitis in horses, also known as heaves or recurrent airway obstruction, is a chronic, non-infectious airway condition that is caused following exposure to allergens such as pollen, dust or fungal spores.
- Common causes of exposure are hay and straw.
- This condition causes the airways to become obstructed, leading to difficulty breathing. This increased respiratory effort may lead to the development of a heave line due to enlargement of the abdominal muscles.

- What would help to treat a cow with fusobacterium necro foot rot?
- Bandage
- Wire affected claw to unaffected claw
- Systemic antibiotics
- Topical anesthetics/never block
Systemic antibiotics
- Footrot is caused a combination of the bacteria Fusobacterium necrophorum and Dichelobacter (formally Bacteroides) nodosus (more common in sheep), and Bacteroides melaninogenicus (more common in cattle).
- Fusobacterium necrophorum is a normal inhabitant of the ruminant digestive tract and may survive in soil for up to ten months. It produces a leukocidal exotoxin that reduces the protective white blood cells from ingesting bacteria (phagocytosis) and causes suppurative necrosis.
- Penicillin and oxytetracycline are effective antibiotics if started early in the disease process and given at the recommended dosage
- What one finds on necropsy with Bacillary hemoglobinuria (redwater disease)?
- Hepatic infarct
- Renal infarct
- Splenic infarct
Hepatic infarct
- Bacillary hemoglobinuria is an acute, infectious, toxemic disease caused by Clostridium haemolyticum. It affects primarily cattle but has also been found in sheep and rarely in dogs
- C haemolyticum is a soilborne organism naturally found in the GI tract of some cattle.
- It can survive for long periods in contaminated soil or in bones from carcasses of infected animals. After ingestion, latent spores ultimately become lodged in the liver. The incubation period is extremely variable, and onset depends on the presence of a locus of anaerobiosis in the liver.
- Such a nidus for germination is most often caused by liver fluke (Fasciola hepatica) infection, rarely by high nitrate content of the diet, accidental liver puncture, liver biopsy, or any other cause of localized necrosis. When conditions for anaerobiosis are favorable, the spores germinate, and the resulting vegetative cells multiply and produce β toxin (phospholipase C).
- This causes intravascular hemolysis, resulting in hemolytic anemia and hemoglobinuria.
- Antibiotic for 2 day old septicemic calf?
- Ceftiofur
- Gentamicin
- Pen G

- Bluetongue is an insect-borne, viral disease affecting sheep, cattle, deer, goats and camelids (camels, llamas, alpacas, guanaco and vicuña).
- Although sheep are most severely affected, cattle are the main mammal reservoir of the virus and are critical in the disease epidemiology.
- he disease is non-contagious and is only transmitted by insect vectors (midges of the Culicoides species).
- The disease is caused by a virus belonging to the family Reoviridae
- Goats, cattle, and wild ruminants such as deer can appear healthy when infected. This can lead to silent spread by midges feeding on the infected animals.

Gossypol (cardiotoxic)
- Gossypol poisoning, usually chronic, cumulative, and sometimes insidious, follows consumption of cottonseed or cottonseed products that contain excess free gossypol
- Prolonged exposure can cause acute heart failure resulting from cardiac necrosis
- Pulmonary effects, labored breathing, and chronic dyspnea are most likely secondary to cardiotoxicity from congestive heart failure.
- Hepatotoxicity can be a primary effect from direct damage to hepatocytes or metabolism of phenolic compounds to reactive intermediates, or liver necrosis may be secondary to congestive heart failure.

Ixodes
- Lyme disease, also known as Lyme borreliosis, is a bacterial illness that can be transmitted to humans, dogs, and other animals by certain species of ticks.
- it only causes symptoms in 5-10% of affected dogs. So some dogs may have it, but never show symptoms.
- When infection leads to Lyme disease in dogs, the dominant symptoms are:
Recurrent lameness due to inflammation of the joints
Fever1
General feeling of malaise
Many dogs who develop Lyme disease have periodic lameness because their joints are inflamed. Sometimes the lameness lasts for only 3-4 days but recurs days to weeks later, either in the same leg or other legs.
This is known as “shifting-leg lameness.” One or more joints may be swollen, warm, and painful.
- What is the best way to control Strongylus vulgaris in a horse ranch with high stocking of 0.25 acres/horse?

- Habronemiasis
Habronemiasis (stomach worm)
- The larvae emerge from flies that feed on wounds or secretions from around the eyes or genital region.
- When the larvae emerge from flies feeding on preexisting wounds or on moisture of the genitalia or eyes, they migrate into and irritate the tissue, which causes a granulomatous reaction.
- The lesion becomes chronic, and healing is protracted. Diagnosis is based on finding nonhealing, reddish brown, greasy skin granulomas that contain yellow, calcified material the size of rice grains.
- What can you give to a mare to decrease OCD in her foal?
- Supplement calcium
- Supplement phosphorous
- Supplement copper
Supplement copper

What is Epizootic Bovine Abortion?
(EBA)
- Foothill abortion in cattle, also known as epizootic bovine abortion (EBA), is a tick-borne disease caused by the bacteria Pajaroellobacter abortibovis.
- It is a significant problem for beef producers in foothill and mountainous regions of California, Northern Nevada and Southern Oregon
- Epizootic bovine abortion usually causes a protracted abortion storm affecting primarily heifers or cows recently introduced to the geographic region; however, abortion can occur 3–5 months after leaving the endemic area.
- Abortion is usually in the last trimester, and rates may be as high as 60%. The animals abort without illness, and the fetus is seldom autolyzed.
- Appearance of Fetus:
- hepatomegaly, splenomegaly, and generalized lymphomegaly (Merck)
- A)hemorrhagic thymus, enlarged spleen B) gunmetal or whatever blue colored organ
- Microscopically, there is marked lymphoid hyperplasia in the spleen and lymph nodes and granulomatous inflammation in most organs.
- Fetal IgG is increased.
- Cows seldom abort in subsequent pregnancies, and heifers are often exposed to endemic areas before breeding age in an effort to prevent abortions.
What are oats high in?
Phosphorus
(therefore may need to supplement Ca in oat heavy diets)
Clinical Signs of BSE
- BSE (bovine spongiform encephalopathy) is a progressive neurological disorder of cattle that results from infection by an unusual transmissible agent called a prion –> Prion Disease
- Initial clinical signs are subtle and behavioral in nature. The spectrum increases and progresses over weeks to months, with most animals reaching a terminal state by 3 mo after clinical onset.
- Commonly observed clinical signs include hyperesthesia, nervousness, difficulty negotiating obstacles, reluctance to be milked, aggression toward either farm personnel or other animals, low head carriage, hypermetria, ataxia, and tremors.
- Weight loss and decreased milk production are common. Yet, in a large portion of affected animals, clinical signs may be nonspecific, and involvement of the nervous system is not obvious in every case.
What Mastitis pathogen can be eradicated?
Streptococcus agalactiae
Intra-mammary infusion of antimicrobials following the last milking of the lactation (dry cow therapy) can greatly reduce the cases of Streptococcus agalactiae mastitis by eliminating existing infections and controlling new infections early in the dry period.
Treatment for Anaplasma marginale in cows?
Oxytetracycline
- Up to 17 different tick vector species (including Dermacentor, Rhipicephalus, Ixodes, Hyalomma, and Argas) have been reported to transmit Anaplasma spp. Not all of these are likely significant vectors in the field, and it has been shown that strains of A marginale also coevolve with particular tick strains
- There is a strong correlation between age of cattle and severity of disease. Calves are much more resistant to disease (although not infection) than older cattle. This resistance is not due to colostral antibody from immune dams. In endemic areas where cattle first become infected with A marginale early in life, losses due to anaplasmosis are minimal.
Treatment for Salmon Poisoning
Doxycycline and fenbendazole or Praziquantel
- Salmon Poisoning Disease is a potentially fatal condition seen in dogs that eat certain types of raw fish. Salmon (salmonid fish) and other anadromous fish (fish that swim upstream to breed) can be infected with a parasite called Nanophyetus salmincola.
- Overall, the parasite is relatively harmless. The danger occurs when the parasite itself is infected with a rickettsial organism called Neorickettsia helminthoeca. It’s this microorganism that causes salmon poisoning.
- Salmon poisoning occurs most commonly west of the Cascade mountain range
Possible complication of giving a horse steroids?
Laminitis
Is Acetominophen an NSAID?
NO.
- Acetominophen is not an anti-inflammatory or NSAID.
- It relieves minor aches and pains, but doesn’t reduce swelling or inflammation
What is a CVI?
(Certificate of Veterinary Inspection)
- It is good for up to 30 days after a veterinarian perfoms a physical examination
Urinary crystals seen with ethylene glycol intoxication?
(antifreeze)
Calcium Oxalate
- calcium oxalate monohydrate crystals are transported intracellularly by kidney cells, the renal toxicity of ethylene glycol may result from inhibition of mitochondrial respiratory function in proximal tubular cells by calcium oxalate monohydrate crystals
- The best way to confirm ethylene glycol poisoning is by measuring the blood concentration of ethylene glycol.
- A urinalysis may also confirm ethylene glycol poisoning and underlying kidney damage by the presence of dilute urine containing blood, protein, cellular casts (plugs of cells which have taken the shape of dying tubules in the kidneys), and calcium oxalate crystals (which are seen with ethylene glycol poisoning). Lastly, a special black-light lamp (Wood’s lamp) can sometimes be used to examine the urine, muzzle, and paws of the patient to look for the presence of the warning dye which is added to automotive antifreeze.
Placing an esophagostomy tube in cat
(positioning?)
- Place the patient in right lateral recumbency with the left side uppermost.
- The tube can be placed on either the right or left side of the midcervical region; however, the esophagus lies slightly left of midline making left-sided placement more desirable
Where do we see enteroliths in the horse?
Right Dorsal Colon and Transverse Colon
- Enteroliths are mineral accumulations of magnesium-ammonium-phosphate (struvite) around a foreign object (a piece of metal, pebble, bailing twine, hair, rubber) that form round, triangular, or flat stones inside the bowel usually over the course of multiple years.
- They form in the large colon of horses where they can remain for some time until they move and cause an obstruction in the large or small colon, resulting in colic
What does a positive membrane slip in the cow confirm?
That they are approximately 55 days in pregnancy
- The examiner can detect the chorioallantois within the lumen of the pregnant uterus by compressing the uterine horn between the thumb and forefingers, lifting the uterus, and then allowing the horn to slowly “slip” from the grasp.
- If the cow is pregnant, the chorioallantois can be felt to slip through the fingers just in front of the uterine wall. This membrane slip can be felt in the pregnant uterine horn as early as 30 days of pregnancy and can be reliably detected by day 35.
- The fetal membrane slip can be detected in the nongravid horn by approximately day 70 of pregnancy. During early pregnancy, the fetal membranes are thin, and a delicate touch and some experience are required to recognize this sign of pregnancy.
What caused this wound?
Cuterebra larvae
- The adult botfly deposits its eggs in or near the openings of rodent and rabbit burrows.
- After hatching, the botfly larvae, which typically infect rodents and rabbits, enter the host’s body through an opening such as the nose, mouth, or a skin wound.
- After several days, the botfly larvae migrate to the tissues beneath the skin, where they encyst and continue their development.
- Dogs and cats are accidental hosts of Cuterebra larvae. They are most commonly infected when they are hunting rodents or rabbits and encounter the botfly larvae near the entryway to a rodent’s burrow.
- Most cases of warbles in dogs occur around the head and neck.
what is porcine parvovirus?
- Porcine parvovirus (PPV) is a virus disease of pigs caused by a Parvovirus from the Parvoviridae family.
- It is associated with reproductive problems, including abortion, small litters, still births, neonatal deaths and weak piglets.
- There is no clinically apparent disease in non-pregnant pigs. Disease occurs when sero-negative dams are infected in the first half of gestation and the virus crosses the placenta.
- Infection of post-natal pigs occurs without detectable clinical signs. In pigs the clinical picture is variable depending on the stage of when infection occurs. There may be:
- Increased returns to service,
Abortion,
Small litters,
Mummified foetuses,
Neonatal death and weak piglets.
In boars, PPV can temporarily disturb spermatogenesis.
- REPORTABLE TO THE CDFA - California Department of Food and Agriculture
What vaccine must be given in killed form?
Leptospirosis
What happens if a bird ingests avocado?
- The adverse effects in birds have been as quickly as 15-30 minutes after ingestion.
- The first signs that owners usually see are weakness and depression, with fluffed plumage and a reluctance to perch.
- Once respiratory signs start death usually follows quickly
How do we diagnose Toxoplasmosis?
- Toxoplasmosis is usually diagnosed based on a cat’s history, signs of illness, and laboratory test results.
- Measurement of two types of antibodies to T. gondii in the blood, IgG and IgM, can help diagnose toxoplasmosis.
- High levels of IgG antibodies to T. gondii in a healthy cat suggest that the cat has been previously infected and is most likely immune to the organism and not excreting oocysts. These cats are no longer sources of infection for other hosts.
- High IgM antibody levels, in contrast, suggest an active infection. The absence of any T. gondii antibodies in a healthy cat suggests that the cat is susceptible to infection and would shed oocysts for up to two weeks following infection.
Proparicaine in Dogs and Cats
- Proparacaine HCl is a local anesthetic used primarily by ophthalmologists during examinations or diagnostic tests for dogs and cats. Proparacaine basically numbs the eye.
- When applied topically, proparacaine has a rapid onset of action and its effects last for at least 15 minutes. It does not penetrate the eye well, but is absorbed across mucous membranes such as the conjunctiva.
- Although it is related chemically to other anesthetic agents, such as lidocaine, bupivacaine, novocaine and cocaine, it is considered too toxic to be produced in injectable form.
- Prolonged use of this local anesthetic is not recommended because it becomes less effective with multiple applications, is toxic to corneal epithelium, delays healing of corneal defects, and may result in corneal cloudiness. These side effects prohibit the use of proparacaine as a therapeutic agent.
- Excessive amounts of anesthetics applied to mucosal surfaces may cause cardiac or respiratory abnormalities.
What is Chinchilla fur slip?
- Fur slip can occur if your chinchilla is being held tightly and trying to escape, if he is stressed out or if he gets his fur caught on something.
- Typically fur slip is done to “escape” the situation your chinchilla is in
- often related to the stress of handling
- If this happens, use minimal restraint in the future
What is a myringotomy?
- surgical incision into the eardrum, to relieve pressure or drain fluid.
- Can use to assess for otitis media
What is papillomatous digital dermatitis?
- Papillomatous digital dermatitis (PDD) is a polymicrobial infection in soft tissue adjacent to the hoof and is the leading cause of lameness in dairy cattle.
- Treponema phagedenis-like (TPL) spirochetes are a constant feature of PDD lesions and are localized deep in infected tissue
When looking at a canine vaginal cytology, what would indicate the likelihood of high breeding success?
- cornified epithelium
- Rising levels of estrogen cause the vaginal epithelium to become “cornified” - the surface cells become large and flattened, with small or absent nuclei. In essence, vaginal cytology is a type of endocrine assay.
- During estrus the vaginal epithelium is very thick. You will see almost 100% cornification.
Treatment for Chlamydia conjuncitivitis in cats?
doxycycline
Acute death and splenomegaly in a cow?
Anthrax
Mycoplasma mastitis in a cow?
CULL
- Mycoplasma is a contagious pathogen, and thus is transmitted cow-to-cow through infected milk on milking equipment or milker’s hands.
- There is no treatment for Mycoplasma mastitis and once infected, cows should be considered infected for life. The only means of control is identification, segregation and culling
What anaesthetic agent should be avoided in a dog with glaucoma?
Atropine
- Atropine sulfate causes a significant increase in IOP when given both topically and by intramuscular injection. It should be used with caution, or indeed avoided entirely, in dogs with glaucoma or in those with a predisposition to the condition.
What horse breed is predisposed to laryngeal hemiplegia?
Thoroughbreds
- Horses with laryngeal hemiplegia have paralysis of the arytenoid cartilage, which prevents them from abducting or opening their throat during inspiration.
- This leads to decreased airflow into the lungs due to obstruction from the paralyzed cartilage resulting in respiratory noise and exercise intolerance
- Roaring (laryngeal hemiplegia) is a condition in horses that greatly reduces their airflow during exercise. Affected horses make a “roar” sound under work
How to diagnose coccidiomycosis
(Valley Fever)
While coccidioidomycosis can be definitively diagnosed via biopsy, the most common way it is diagnosed is by testing for antibodies to the organism (complement fixation (AGID) = IgG, tube precipiten test = IgM)
- low false positives –> good specificity
- This is a fungal disease caused by the soil fungus Coccidioides immitis
- The early signs of coccidioidomycosis include fever, lethargy, lack of appetite, coughing, and joint pain.
- The dog may develop lameness and/or weakness, as well as back and neck pain. In severe cases, if the organism spreads throughout the body, becoming systemic, the dog may develop seizures or blindness due to the central nervous systems becoming involved.
Toxoplasmosis is associated with what presentations?
anterior uveitis, fever
- Toxoplasmosis is a common infection from the microscopic parasite Toxoplasma gondii. It appears in many species of animals, but cats are the most common that transmit the parasite to humans
Drug used for parasite control in reptiles
- Fenbendazole
- Ivermectin (not in turtles/tortoises!)
Time it takes for a mare to develop antibodies to local pathogens?
4-6 weeks
How often should horses be vaccinated for tetanus?
annually
Diagnostic to run for nutritional myodegeneration?
- Whole blood selenium or liver selenium
- Plasma Vitamin E
HYPP horse diet changes?
need to aim to reduce Potassium content!
- decrease alfalfa
- increase timothy hay/grass
- put out to pasture
- feed several times a day, exercise regularly
Two pathogens involved in footrot?
Dichelobacter nodosus and Fusobacterium necrophorum
- It is caused by Dichelobacter nodosus, a pathogen apparently highly specialised for feet, while Fusobacterium necrophorum, a secondary pathogen in footrot is reportedly ubiquitous on pasture
- Have to treat fusobacterium necrophorum footrot with systemic antibiotics and local wound therapy
Strongylus vulgaris infects which animal?
control measures?
Horse
- blood worm of the horse (nematode)
- Strongylus vulgaris has at times been a very common parasite in horses; it was estimated that it was present in 90% to 100% of horses in the U.S.
- The inflammation caused by the strongyle travelling throughout the arteries and intestines can cause blood clots to form.
- The clots can block oxygen passage to the intestines, causing parts of them to die.
- Ultimately, besides causing abdominal pain (colic) in equines, the complications from S. vulgaris infestation can lead to death
- Control measures: clean up and compost manure biweekly
4 types of predisposition to urolithiasis in horses?
- Urine constituents
- Nutrition
- Gender
- Bacterial
Surgical correction for an LDA?
- left sided paralumbar fossa abomasopexy
- right sided paralumbar fossa omentopexy
HOWEVER
- Right paramedian abomasopexy and right paralumbar fossa omentopexy appear to be the most widely used means of correcting left displacement of the abomasum in dairy cattle
- LDA can be corrected surgically using right flank pyloric omentopexy, right paramedian abomasopexy, left paralumbar abomasopexy, combined left flank and right paramedian laparoscopy (two-step procedure), or left flank laparoscopy (one-step procedure)
Status of TB and Brucella in California?
- TB = was “Accredited free” for TB, but United States Department of Agriculture (USDA) downgraded California’s TB status to “Modified Accredited Advanced” in September 2008.
- Brucella = Brucella free
- California has been brucellosis free since 1997. The disease may be avoided by employing effective sanitation and management practices
BRSV clinical signs in calves?
- BRSV has a predilection for the lower respiratory tract, where it can cause varying degrees of pneumonia by itself.
- Secondary bacterial infections, frequently involving Mannheimia (Pasteurella) haemolytica, causes disease of greater severity or death. Transmission is via respiratory aerosols or from direct contact with infected cattle.
- Clinical disease from uncomplicated BRSV tends to favor young, previously unexposed cattle, although mature animals can be clinically or subclinically infected.
- Clinical infection produces high fever, increased respiratory rate, spontaneous coughing, and nasal discharge.
- Diffuse interstitial pneumonia and emphysema
