DL Flashcards
what does a reduced urea, creatinine and cholesterol indicate
hepatic disease
Test for portosystemic shunt
bile acid stimulation test
Ultrasound: small liver, large kidney and bladder crystals
cause of cerebellar hyperplasia in calves and lambs
Calves: BVDV (in utero infection <180days)
Lambs: Blue tongue virus or boarder disease virus
causes of cerebellar hypoplasia in kittens and V/D + reduced white cell counts in adult cats
Feline Parvovirus
cause of ataxia, paralysis and recumbency. Lesions in spinal cord in a horse. How is it diagnosed
Equine Herpesvirus 1
PCR to detect virus in blood sample
which pathogen causes feline infectious peritonitis
Feline Coronavirus: causes immune mediated complexes that get trapped in small blood vessels and cause vasculitis(WET FORM) or cell mediated against infected macrophages causing granulomatious DRY form in organs
Cause of yellow exudation and hemorrhage on pigs brain, common clinical signs
Bacterial meningitis causes by Streptococcus Suis
Paddling, nystagmus, and seizuring before sudden death
Cow with Behavioral changes, muzzle tremours, abnormal posture, tenesmus and excess salivation
Rabies : Nergi bodies
tenesmus
straining to defecate but cannot
Anisocoria
unequal pupil size
Proptosis of the globe
eye moved forwards and trapped there by the eyelids
blepharospasm
abnormal twitch of the eyelid
appropritae treatment of a prolasped 3rd eyelid
surgical reposition with topical antibiotics and steroid to go home
known causes of kertatoconjunctivitis sicca
Drug Toxcity, Trauma to lacrimal gland, removal of the 3rd eyelid, radiation therapy, immune-mediated
tarsorrhaphy
eyelids sown together
aqueous flare, miosis, conjunctival congestion, colour change to eye/iris are all suggestive of intraocular inflammation specifically anterior uveitis/iridocyclitis
are all suggestive of intraocular inflammation specifically anterior uveitis/iridocyclitis
evidence of orbotal cellulitis
exophthalmos, strabismus, protrusion of the 3rd eyelid, mucopurulent ocular discharge
main cause of red eye in a horse
corneal ulcers causing secondary anterior uvitits
main causes of recurrent uveitis in a horse
immune-mediated: Leptosprosis or trauma (sparp=corneal ulcer or blunt= no corneal ulcer)
RARE: neoplasia and lens luxation
leading cause of blindness in horses
equine recurrent Uvieitis causing secondary cataracts, glycoma, lens luxation or retinal detachment.
possible causes of cataracts in a dog
Age, trauma, retinal detachment, anterior uveitis, heritable and diabetes mellitus
alopecia, papules, erythema, and crust on dogs abdomen DDX?
Parasites: chytella, scabies, thrombicular, demodex
Microbial skin disease: staph or malassezia
hypersensitivity: FAD (usually dorsal) Atopic dermatitis
top 6 causes of skin disease
Scabies, Staph, Malassezia, FAD, food hypersensitivity and atopic dermatitis
common lesions sites for atopic dermatitis
Feet pads, ventrum, bum, ears, mouth,
cause of erosions on the lips of a cat
Rodent ulcers (indolent ulcers): Allergic disease treatment: allergen avoidence (flea/food), steroid or antibiotics
DDX for pruritic skin disease in a horse
Paracites:lice, chorioptes(distal limbs), scabes, psoroptes(tail+head), harvest mites
Microbial: dermatophilosis, pyoderma, dermatophytosis
Hypersensitivity: culicoides, food, atopic dermatitis
approach to pruritis
always rule out parasitic cause then microbial then move onto hypersensitivity
main lesions of feline allergic skin disease
Miliary dermitits: focal crusts on dorsum
Indolent Ulcer: Lip
Eosinophilic Plaque: alopecia+ erosive ulcer on trunk/inguanal/thigh
Linear granuloma: same as plaque but linear
main DDx for allergic skin disease in a cat
Flea, food atopic, cheyletiella, harvest mite, FB, dermatophytosis, neoplasia
test for allergic skin disease
History, Parasites[Skin scrape, hair pluck, coat brush]
Cytology, culture(fungal/bacterial), Allergy[skin test food trial]
most likly cause of severe head and neck puritis in a cat
Food Allergy!
cause of coat discoloration in a calf
Copper deficiency
cause of wool break (weak wool)
Stress, ruminal acidosis or disease
most common cause of equine uticaria
drug or vaccine reaction
parallel rows of cocci on histology
‘railroad’ dermatophilosis
