Brucellosis of cattle, also known as "contagious abortion" and "Bangs
disease", is caused by infection with the bacterium Brucella
abortus, which can also cause a disease of humans known as "undulant
fever". Brucellosis infection of cattle causes abortion or
premature calving of recently infected animals, most often between the
fifth and eight month of pregancy. Although federal and state regulations
have helped to control this disease, there is still a threat. Infected
cows frequently suffer from retained afterbirth, are difficult to get
rebred and sometimes become sterile.
Brucellosis is spread from the female animals genitals discharge of an infected cow
or from an aborted fetus. The organism has an affinity for the
reproductive tract and abortions, retained placenta, weak calves and
infertility frequently occur. Breeding bulls which are infected,
can transmit the disease to cows at the time of service by infected semen. Milk
produced front an infected cow may also harbor the organism. The
infected milk creates a public health hazard as this is the organism
that causes undulant fever in humans.
There is no treatment for Brucellosis. Prevention of Brucellosis is
accomplished by official calfhood vaccination of heifer calves. Vaccination
must be done by an accredited veterinarian at calf ages that vary from
two to four months using standard dosage vaccine, or from 4 to 12 months
using reduced dosage vaccine. Each calf must be identified as officially
vaccinated in compliance with state and federal regulations. Quarantines
are imposed on infected herds by state and federal authorities until
the herd has been proven free of the disease.
