Caprine and ovine brucellosis:
- Caused by B. melitensis
- Goats more susceptible
- Abortion, orchitis in males, arthritis, hygromas
- May not have protective immunity following abortion
- Rose Bengal agglutination test and complement fixation test
- Test and slaughter where exotic
Ovine epididymitis
- Caused by B. ovis
- Epididymitis in rams and placentitis in ewes
- Reduced fertility in rams, sporadic abortion and peinatal mortality
- Venereal transmission
- Long latent period in rams following infection (present in semen 5 weeks after infection)
- Premating checks on rams - serological tests and scrotal palpation
- Testicular atrophy and swollen epididymis in chronically-infected rams
- Agar gel immunodiffusion test, complement fixation test and indirect ELISA
- Vaccination of young rams with B. melitensis vaccine or B. ovis bacterin

+**Venereal transmission
-''Brucella melitensis'' is one of the '''[[Bacteria |bacterial organism]]''' responsible for [[Ovine Brucellosis | '''Ovine Epididymitis''']], along with ''[[Brucella ovis]]''.

+**Premating checks on rams - serological tests and scrotal palpation
+**Testicular atrophy and swollen epididymis in chronically-infected rams
+**Agar gel immunodiffusion test, complement fixation test and indirect ELISA

-''Brucella melitensis'' however can also infect cattle, unlike ''[[Brucella ovis]]''.

-It is one of the [[Brucella species |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 '''[[Stomoxys calcitrans | 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 [http://www.oie.int/ (OIE)].
