(Corynebacterium Pseudotuberculosis)

  1. Disease
  2. Host
  3. Transmission
  4. Clinical Signs
  5. Path
  6. Diagnosis
  7. Treatment
  8. Immunity
  9. simllar to what?
A
  1. Caseous lymphadenitis in sheep/goats

ulcerative lymphaginitis in cattle/horse

  1. sheep, goats, cattle, horses
  2. through skin from contaminated soil
  3. (cattle/goat/sheep)

skin –> LN of neck/lungs –> abcesses in head/neck region

(horses)

same thing but in lower pectoral limb

  1. Cx, smear
  2. lance LN, topical Abx
  3. no vx
  4. mycoplasma, cell wall has high content (resistant to phag killing)

  9. why worse in old?
A
  1. Bovine Anaplasmosis
  2. cattle, deer, bison, ruminants
  3. tick/flies (mechanical too)
  4. acute = fever, death

chronic = emaciation/anemia

  1. invaginate RBC (inclusion bodies contain parasites)
  2. culture, smear
  3. aureomycin in beef feed, oxytetracyline
  4. none (mess up surveillance)
  5. greater immune response

  4. acute/sub/chronic

genx

  1. C’s infect monocytes

Q

(Neorickettsia Risticii)

  1. Disease
  2. Host
  3. Transmission
  4. Clinical Signs
  5. Path
  6. Diagnosis
  7. Treatment
  8. Immunity
  9. How different from other Rickettsiales
A
  1. Potomac Horse Fever (equine monocytic ehrlichiosis)
  2. horses & ponies
  3. ingestion of infected freshwater snail
  4. high fever, bloody diarrhea, abort in mid trimester
  5. rep in intestinal tract
  6. serology

support

  1. vx (doesn’t guarantee protection)
  2. unlike other Rickettsiales - high strain variation (affects severity)
