Brucella neotomae

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.

Pathogenesis & Disease[edit]

The bacterium causes severe inflammation of the epididymis, causing formation of spermatocoeles and fibrinous adhesions. This disease is known as ovine brucellosis. It can also cause epididymitis in cattle. Ovine brucellosis is a reportable disease in USA.[1] A cure for it was discovered by Sir Temi Żammit in the early 1900s.

It is also reported to cause reproductive disease such as orchitis, mastitis, and abortions.
