Midwest, GI and respiratory, radiographs w/ Diffuse or linear, nodular interstitial pattern, hilar lymphadenopathy,
pleural effusion
Histoplasmosis
treat w/ Itraconazole
Hunting dogs, Ohio & Mississippi River, respiratory signs, thick walled budding yeast

itraconazole otherwise
cats, Pacific NW, roman nose & respiratory signs, round thick capsuled fungi on cytology
Cryptococcus

front feet lameness, lameness switches to other foot after palmer digital nerve block, positive heel pain on hoof tester, “reverse oreo” on sole radiographs; dz, treatment
navicular syndrome
treat by improving breakover, wedge or heel pad
lameness worsens after flexion of joint, can have joint effusion
osteoarthritis
○ “Bone spavin” = hock (especially intertarsal) joint OA
○ “High ringbone” = pastern joint OA (proximal interphalangeal)
○ “Low ringbone” = coffin joint OA (distal interphalangeal)
○ Lameness, often acutely nearly not-weight bearing
○ Increased digital pulse, heat in hoof
○ Positive to hoof testers throughout foot
○ coronet band may become soft and sensitive to palpation focally
dzand treat?
hoof abscess
- drain & poultice
