• Infectious pustular vulvovaginitis (IPV)
• Infectious pustular Balanoposthitis (IPB)
• Abortion

Often part of shipping fever complex

• makes Dx difficult

Question 4

EHV-1 vs EHV-4

Answer 4

• EHV-1 (nasty guy does a lot)
  
  • abortion
  • paralysis
  • respiratory dz
• EHV-4
  
  • respiratory dz

Question 5

EHV-3

Answer 5

• Equine coital exanthema

Question 6

Malignant Catarrhal fever

Answer 6

• high mortality out west
• Sheep can give cows malignant catarrhal fever (mucupurulent d/c nose)
• WIldebeest can give cows
• No treatment, high mortality death sentence for ze cow
• Virus shed during birthing process
• dz not seen in indemic hosts

Question 7

Poxviruses

Answer 7

• Viriolation from scabs (Mary chick)
• SKIN
• Giants: brick shaped except parapoxes => helical
• use EM only really in pox viruses from scab
• enveloped
• zoonotic
  
  • orthos
  • paras
• Less host specific
  
  • orthos low host spec

Question 8

Answer 8

Poxvirus virion architecture

Question 9

Foreign animal dz

Answer 9

Cowpox

Capripoxviruses

Question 10

Pseudocowpox virus

Answer 10

• horseshoe shaped lesions on teat
• Milker’s nodule

Question 11

Capripoxviruses

Answer 11

• difference in strain and host
• Lumpy skin dz => high morbidity, low mortality
• Sheep and goats => systemic, high mortality

Question 12

Lumpy Skin dz of cattle (pox virus)

Answer 12

• Distinguish from pseudo-lumpy skin dz (BoVH-2)

Question 13

Avipoxviruses

Answer 13

• Fowlpox common
  
  • lesions on face and wattle, etc

Question 14

Parvovirus hallmarks

Answer 14

• No envelope (longest persisting)
• infect rapidly dividing cells
• SMEDI
• Intracytoplasmic and nuclear inclusions

Question 15

SMEDI syndrome

Answer 15

• Parvovirus dz in pigs
• mostly infertility

Question 16

Canine Parvo - 2 vs feline panleuk

Answer 16

• Canine parvo
  
  • cardiomyopathy (in utero/ at birth infection)
• Feline panleuk
  
  • cerebellar hypoplasia

*Know pathology, DX, TX

• CBC: low albumen, VERY red WBCs
• Enrofloxacin (fluoroquinalone), fluids w/ hetestarch
• Smells baaaad
• Snap test (can use it for both)

Question 17

Circovirus

Answer 17

• small
• naked
• likes WBCs
• BOTRYOID intracytosplasmic inclusions

Question 18

Psittacine Beak and Feather

Answer 18

• infects rapidly dividing cells
• basal epithelial cells
• when exp at early age, malformed feathers (club shaped)
  
  • worse with every molt => crazy viral shedding
