Introduction
Brucella melitensis is one of the bacterial organism responsible for Ovine Epididymitis, along with Brucella ovis.
Brucella melitensis however can also infect cattle, unlike Brucella ovis.
It is one of the Brucella genus of bacteria. There are three known biovars.
It is a gram negative coccobacillus that sometimes forms small groups in tissues.
Lifecycle
Brucella melitensis can be transmitted by the stable fly.
Pathogenesis
Severe inflammation of the epididymis particularly the tail cause formation of spermatocoeles and fibrinous adhesions.
Diseases
B. melitensis causes Ovine Brucellosis (Epididymitis). It can also cause epididymitis in cattle.
The disease is notifiable to the World Organisation for Animal Health (OIE).
