A small gram-negative non-spore forming and non-motile pathogenic bacteria involved in zoonotic disease that cause systemic symptoms in various organs and tissues known as Brucellosis.


Brucella melitensis has two circular chromosomes encoded for DNA replication, core metabolism, protein synthesis and cell wall biosynthesis. It contains O-polysaccharides on the outer membrane of the bacterium that designates whether it look smooth or rough.

Brucella melitensis is an aerobic organisms yet it may require an atmosphere containing carbon dioxide which mainly interacts with animals like goat and sheep that in turns serves as a vector in human infections due to contaminated or poorly pasteurized milk and cheese products. These bacteria flourish in phagocytic cells of its host and it has a unique factor in scheming the presence or absence of the disease.

Brucella melitensis is implicated in Brucellosis, a fatal zoonotic disease that affects multiple organ systems particularly the immune response induced by infections that occurs when the bacteria able to transfer from farm animals to humans that localized intracellularly once inside the host and persist for several weeks in the blood.
