Brucella melitensis

Brucella melitensis is a gram negative coccobacillus bacteria from the Brucellaceae family. The bacterium causes Ovine Brucellosis, along with Brucella ovis. It can infect sheep, cattle, and sometimes humans and it can be transmitted by the stable fly. It is zoonotic, unlike Brucella ovis, causing Malta fever or localized brucellosis in humans.
