Brucellosis, also known as Bang's disease, is a contagious disease in animals caused by the bacterium Brucella abortus. It is transmitted between animals through ingestion or inhalation of contaminated materials from aborted fetuses or birthing discharges. Symptoms include abortion in late pregnancy as well as retained placentas and weak newborn calves. Diagnosis involves isolating the bacterium from aborted fetal tissues or testing milk and blood samples. While antibiotics can treat infected animals, vaccination of young cattle is the most effective control method for preventing transmission and economic losses to livestock operations.

2. Define:-
• It is an acute or choronic contagious disease animal.
• In India, disease causes an annual economic loss of
Rs 240 million due to abortion, infertility and reduced
milk yield.
• It is comman in sexually mature animal.It is major
zoonatic disease in India.

3. Brucellosis in Cattle

4. Etiology:-
• It is caused by Brucella abortus.
Transmission:-
The disease spreads through-
 Ingestion of feed & water contaminated with discharge of
abortion foetuses.
 Inhalation
 Vagina during coitus
 Abraded skin or conjnctiva

5. Brucellosis in cattle
(Contagius abortion )
Transmission of others
animals Brucellosis in
cattle (Contagius
abortion )

6. Symptoms:-
 Abortion mainly during advance or late pregnancy.
 Retention of placenta
 Opaque vagina discharge
 Infetility i.e. swelling of scrotum in bull
 Orchitis i.e. swelling of scrotum in bull
 Weak calves are born fromaffected cows

7. Aborted cow fetus due
to brucellosis with
edema opaque and
bleeding

8. Diagnosis:-
 History of strom of abortion in herd
 Isolation of the orgeanism from aborted foetuses, placenta etc
 Milk ring test (M.R.T.)
 Plate or tube agglutination test
Treatment:-
 There is no known treatment which can ccure brucellosis in domestic
animal
 Oxytetracycline ,Sterptomycin in may , however, be tried

9. Control:-
 Test entire herd for brucellosis atleast once in a year.
 Slaughter of infected or carrier animal.
 Adopt AI practice as far as possible.
 Proper disposal of aborted foetuses, placenta and uterine
discharge.
 Disinfection of infected premises.
 Newly purshased animal should be tested for brucellosis twice at
an interval of 30 days before introduction in a herd.
 Pregnant animal should not be purchased.
 General measures:-

10.  Vaccination:-
 If incidence of disease in herd is more ,then calves between 4-8
month of age should be vaccinated byb using Brucella Cotton -19
stain vaccine @5ml S/C called as calfhood vacccination.
