T
Brucella abortus can colonise the udder and shed with the milk of cows.
T
Brucella abortus can colonise the testicles, epididymis and accessory genital glands and shed with the semen.
T
epididymis, testicles, accessory genital glands
Cattle can be asymptomatic carriers of brucellae
T
Infected cattle carry brucellae lifelong
T
Lifelong carriers and shedding!
Calves can be infected with brucellae during pregnancy if the cow is infected.
F
Bovine brucellosis is caused by Brucella bovis
F
Brucella abortus
Brucella melitensis can cause abortion in cattle

NO TREATMENT
Brucella abortus can colonise only pregnant cows or heifers
F
Brucella abortus can cause abortion of cattle
T
Brucella abortus and brucella melitensis can cause bovine brucellosis.
T
both can cause abortion
Bovine brucellosis has to be treated 4-6 weeks long with penicillins
