It has zoonotic
importance. Brucella abortis (in bovine and babeline), Brucella malletanis can
also cause abortion in bovine and babeline.

Diagnosis
Isolation:
For this purpose freshly aborted fetus is best one with placenta. If
placenta is not shed yet, then fetus sample. Preferably fresh fetus
should be sent. Whole fetus is kept in plastic bag and sent to lab
as early as possible preferably within 24 hours. It depends upon the
season also. Suppose extreme summer season, it is better to add bag
with ice cubes. If there is need to preserve, go for refrigeration.
Serological Test:
MRT
(milk ring test), RBPT (rose bangal plate test), ELISA (enzyme
linked immunosorbent essay), SAT (serum agglutination test). First
two are for screening, ELISA and CFT are for confirmation. Suppose
10% aborted; first go for confirmation, remaining for screening.
There are some
non infectious causes. Additionally sampling of fetus and placenta,
also send the sample of food and water. 5g of fodder cover in
plastic bag and send to lab for examination of mycotoxin, aflatoxin
and even for the nutritive value.
In males Brucella
is isolated from primary and accessory sex glands. Semen sample
could be used for this purpose. Treatment of bull is required. In
male there will be undulant fever and orchitis. If there is orchitis,
it will affect the spermeogram.
Control and Eradication
-
Problem come
when outbreak.
-
First
separate aborted animal from the normal.
-
Then go for
treatment.
-
Then you have
to care for vaginal discharge.
-
Then secure
the boundaries of the farm.
-
Then observe
strictly the hygienic measurement at entry.
-
There should
be proper disposal of aborted material.
