Hello friends,
We will discuss about Brucellosis in cattle
Etiology/Cause:-
:- Main Etiological agent that cause Brucellosis - Bacteria Brucella There are 5 Brucella bacteria each causing a different form of disease
(a)Brucella abortus - Affect Cattle, causing bovine brucellosis (Contagious abortion)
(b)Brucella ovis - Affect sheep ,causing Ovine brucellosis
(c)Brucella melintensis- Mainly affect Female goats, causing Caprine brucellosis
(d)Brucella suis - Affect pigs causing Swine brucellosis.
(e)Brucella canis- Affect Dogs,causing Canine brucellosis.
Brucellosis in Cattle :-
(1) Brucella abortus is highly contagious , spreading very easily between cattle as the calf .
(2) Zoonotic disease means it transmitted animals to humans.
Symptoms in Animals:-
Diagnosis can be done by laboratory testing of blood or milk samples or by laboratory culture of brucella abortus from the placenta, vaginal discharge or the milk of infected cows.

Brucellosis in Cattle :-
(1) Brucella abortus is highly contagious , spreading very easily between cattle as the calf .
(2) Zoonotic disease means it transmitted animals to humans.
Symptoms in Animals:-
- Abortion
- Stillborn
- Weak calf born
- Retention of fetal membranes;
- Signs of infection in the membranes;
- Swollen testicles in bulls
- Knee Hygroma
Symptoms in Humans :-
(1) Intermittent Fever ( Undulating Fever)
(2) Flu like symptoms
(3) Orchitis in Male (inflammation in testicles)

Diagnosis:-
Diagnosis can be done by laboratory testing of blood or milk samples or by laboratory culture of brucella abortus from the placenta, vaginal discharge or the milk of infected cows.
Treatment:-
(1) No treatment is available, which makes detection and prevention essential.
.Calfhood Vaccination:-
At the age of 4-8 months calf we should vaccinate by Live strainof Brucella abortus S-19 ( Bruvax) dose rate - 2ml s/c once in life .
.Another Vaccine RB-51
Prevention:-(for Animal)
(1) Testing herds regularly and culling has been an effective way of eradicating the disease in individual herds before.
(2) Quarantines are placed on infected herds and good sanitation and biosecurity will protect uninfected herds.
(3)In endemic areas vaccination is available. In some areas wild populations of buffalo, bison or cattle can carry the disease and infect domestic animals if they come into contact. Vaccination is not a guarantee but can increase resistance to infection.
Precaution:-(for Humans)
(1) Always use /drink Boil milk instead of Raw milk .
(2) Always use gloves during removing fetal membrane
Thank you
