what diagnostics do you do for T. equigenitalis
preventative care?
“test breeding” where you mate a stallion with 2 CEM free mares
3 sets of cultures to be deemed negative (highly fastidious)
charcoal-specific transport media
APHIS regulatory testings
T. equgenitalis transmission

virulence factors
pathogenesis
gram - curved rod
microaerophile
non-spore forming
darting motility in culture
LPS, capsule
zipper & trigger mechanism, T3SS in GI and also preputial crypts of carrier bulls
Campylobacter jejuni
species (reservoirs and vectors)
clinical signs
diagnostics
risk for ______
sheep, other ruminants, ferrets, dogs/cats, humans (reservoirs)
poultry most common vector
necrotizing hepatitis and abortions
fecal, post-mortem culture, PCR, NO cytology bc of CLOs
Guillain Barre Syndrome in humans
Campylobacter fetus venerealis
species

coital (sex)
Campylobacter fetus fetus
species
clinical signs
diagnostics
ruminants
abortion & abortion storms
Weybridge Medium or Clark’s Medium, PCR, Glycine Tolerance Test; need to distinguish C. fetus subspecies because venerealis is reportable; sample same time for Tritrichomonas
______ is the most important campylobacter spp. in sheep but ______ is more common
C. fetus fetus
C. jejuni
_____ Campylobacter spp. is reportable
C. fetus venerealis
