food/fiber URT virus and bacti Flashcards
atrophic rhinitis cause and treatment
b. bronchiseptica then secondary p. multocida D
tetracylines and vaccinate with combo vax
pig URI signs stress, dry cough, fever, seasonal
orthopmyxo swine flu.
chronic dry cough, not growing, bronchopneumonia, last batch of pigs also had
Mycoplasma hyopneumoniae
treatment and prevention of mycoplasma pneumonia
tetracyclines and vaccinations
fibrinous pneumonia, congestion, infarcts in pigs that just had stress
actinobacillus pleuropneumoniae
treatment for a. pleuropneumoniae
ceftiofur in feed
treated multiple times and they relapse, severe pleuritis, chronic damage to lung in pigs
p. multocida A (pasteurellosis)
prevention of pasteurellosis (p. multocida A) in pigs
control primary infections
abortions and nursery piglets have respiratory dz.
PRRSV
what does PRRSV affect
PAMs and PIMs (macrophages) swollen ln
T/F you can vaccinate for PRRSV
false you can only vaccinate for PRRSV if it is already in your herd because it is a live vaccine
Porcine circovirus. affects who and what does it look like?
7-16wk old piglets,
wasting, pale, anemic, lymphoid depletion, intracytoplasmic inclusion bodies
what predisposes sheep the most to pneumonia
not getting colostrum
what predisposes calves to diarrheal dz
not getting colostrum
when is oestrus ovis commonly seen
late summer early fall
pneumonia virus in lambs
PI3
what are common secondary invaders for lambs with PI3
pasteurella and mannheimia
what do we commonly vaccinate for prior to parturition but there really isn’t any evidence that it helps
PI3 vaccine
treat a sheep for long time and different drugs, doesnt get any better. interstitial pneumonia. likely cause?
OPP for life and develops in adults
what in sheep cause thickening of the alveolar septa and lymphocytic hyperplasia. lungs are grey brown color and firm
OPP
what type of virus are CAE and OPP
non oncogenic retroviruses
what causes pasteruellosis in sheep? in goats?
sheep; mannheimia hemolytica
goats: m. haemolytica and p. multocida
what are common clinical signs in small ruminants with pasterurellosis
hemorrhagic septicemia, pneumonia, otitis media, discharge
what can we use to treat pasteurellosis in small ruminants
sulfas
high fever, pneumonia, arthritis/joint swelling, meningitis in kids, peribronchiolar lymphocytic infultrates
mycoplasma pneumonia (ovipneumoniae/ capricolim, bovis)
treatment for mycoplasma pneumonia
tylosin (no cell wall)
nonresponsive pneumonia, occurs in cooler seasons
verminous pneumonia
causes diptheria in cattle
fusobacterium necrophorum
specifically in bovines, this will relapse, hackling cough, and lower temps than other causes
mycoplasma bovis
when is metaphalaxis usually recommended
if you expect 1/3 to get sick, youve treated 15% of calves in one day
what drugs do you never use to treat BRDV bacti
penicillin, sulfa pills, gentocin
what vaccines should preconditioned calves get
IBR-BVD I and II
7 way
mannheimia with leukotoxin
how to prevent mannheimia infections in cattle?
prevent stressor that allow invasion from the tonsils
what causes cranioventral macroabscesses
teritary mycoplasma infection on top of preexisting bacterial infection
after the initial stressor, when does viral invaders happen and when does the secondary bacti move in
virus: 3 days after
bacti: 3-5 after virus, 1 week after stress
who are the most susceptible beef cattle and diary cattle to BRDC
early feedlot phase,
post weaned calves
