Brucellosis is an infectious disease caused by a bacteria named Brucellawhich spreads from animals to humans ( zoonotic). Different strains of this bacteria are found in cows, dogs, sheep, camels, pigs, goats and marine animals like seal. Some of these strains include, B. melitensis, B. suis, B. canis and B. abortus. It has become a quite serious problem in certain parts of the world, affecting more than half a million of people in about100 countries in an year. A person can get infected by the disease during contact with an infected animal or animal product. Bacteria can enter the body through skin bruises, inhalation of contaminated air and by consuming undercooked meat or unpasteurized milk contaminated with Brucella bacteria. B. canis which is the strain found in dogs can easily infect pet owners incase of contamination with blood or other animal fluids.

These symptoms may appear within 5- 30 days after a contact with an infected animal. However, the symptoms will depend on the strain of bacteria the patient has been affected by. B. abortus will mainly cause mild-moderate symptoms although it can lead a chronic infection. B.suis may cause abcesses in various organs in the body while B. melitensis will cause sudden, severe symptoms which can even lead to disability.
