exam 3 viruses Flashcards
calf 10 days old with diarrhea
bovine coronavirus
bovine rotovirus
no viremia and only isolation from lymph nodes
rotovirus
rotovirus causes
secretory diarrhea from toxin secretion
most severe coronavirus form what has the highest mortality
TGE (alpha)
what do we see with cats with coronavirus
little to no signs unless mutates to FIP
general signs from coronavirus
blunting and necrosis of villi causing malabsorptive diarrhea
what is the necropsy finding of parvoviruses
necrotizing enteritis, necrosis of crypt epithelium, fetal abnormalities, villi blunting
what are the fetal abnormalities caused in dogs and cats by parvovirus
hypoplasia in cats
myocardial necrosis in dogs
what does parvovirus target
nuclei in mitotically active cells BLIST
bovine GI virus that can cause PI animals
BVDV
necropsy finding of BVDV
esophageal ulceration
peyer patch necrosis
fetal abnormalities
necrotic stomatitis in a sheep
small ruminant renderpest (morbillivirus)
what is our hepatitis virus in dogs
canine adenovirus 1
what is the primary target of canine adenovirus 1
vascular and corneal endothelium
petechial hemorrhage in multiple organs and hepatic necrosis in dogs
canine adenovirus 1
syncytial cell formation and peyers patch necrosis in cattle
rinderpest. hopefully you never see this
what strain is BVDV
non-cytopathic strain
age range to cause a PI animal in BVDV
25-150 days gestation
what porcine coronavirus has a vaccine
TGE has a vaccine
PEDV does not
see through intestines, severe blunting and necrosis of villi in a piglet
PEDV
where does FIP infect
macrophages
pyogranulomatous vasculitis in a cat
FIP (alpha covid)
calf diarrhea, no gross histo lesions. virus
rotovirus
where does coronavirus replicate
cytoplasm
where does canine parvovirus replicate
oropharynx and peyers patches
where does feline panleuk replicate
oropharynx and lymphnode
when do we see mucosal disease in BVDV
PI animal infected or mutated to cytopathic form
what are our DNA viruses
parvovirus, canine adenovirus 1
equine coronavirus
self limiting minor diarrhea for a couple days
where does rotovirus replicate
in entrocytes
peyers patch necrosis of a bovine
BVDV
target sites in parvoviruses
Bone marrow
Lymph nodes
Intestinal crypts
Spleen
Thymus
