Adult Bovine Diarrhea Flashcards
(29 cards)
what is winter dysentery
v contagious, acute/peracute diarrheal disease, unknown cause
signs of winter dysentery
sudden explosive diarrhea, etc, runs course in 3-5 days
how winter dysentery is spread
fecal oral contamination
Paratuberculosis is also called
Johne’s Disease
what is paratuberculosis and what causes it
chronic diarrheal disease in ruminants, caused by Mycobacterium avium ss Paratuberculosis (MAP)
signs of Paratuberculosis
slow onset of chronic, watery manure and illness
how paratuberculosis is spread
fecal oral contamination, young can acquire from older but don’t show signs until older (long incubation period)
This viral form of diarrhea is subclinical 70-90% of the time
Bovine Virus Diarrhea (BVD)
even if an animal affected by BVD is subclinical they still experience
production loss and act as carriers
when animals do show clinical BVD signs they are
poor reproductive performance (poor fertility/ low conception/ abortions/still births)
BVD most heavily affects
calves born via dam infected during pregnancy. may be born dead, w/ congenital malformations, carriers, PI calves
what are persistently infected or PI calves
calves infected (BVD) appear normal but shed massive amounts of the virus and never become immune
in what case would a pregnant dam contracting BVD be beneficial to the calf
some calves may be born w ability to produce antibodies against BVD
how to treat BVD
supportive care, PI calves never cleared (euthanized)
there are two kinds of BVD vaccines
modified-live and killed, which is given to who
mod live= non-pregnant
killed= pregnant (must have killed or could infect fetus)
what is Listeriosis, what causes it
ruminant neurological disease caused by Listeria monocytogens (found in environment and enters thro break in skin/ MM and travels to brain)
signs of Listeriosis
nerve damage, unilateral (circling to one side, unilateral face paralysis), ataxia
how to treat Listeriosis
Antibiotics
slow growing tumor unlikely to spread
benign
fast growing tumor likely to spread
malignant
-oma usually refers to
benign tumor
-carcinoma usually refers to
malignant tumor
-sarcoma usually refers to
malignant tumor originating from connective tissue
viral-induced neoplasia of cattle, slow onset, fatal
B Leukosis Virus (BLV)/ Bovine Leukemia
