The isolation of Brucella melitensis biovar 3 from a testicular hygroma of a ram in a nomadic flock of sheep and goats in western Sudan.

Brucella melitensis biovar 3 was isolated from a testicular hygroma in a ram from a nomadic flock of sheep and goats serologically positive for brucellosis and with a history of occasional abortions. The affected testis was enlarged, extensively damaged and contained fluid. The isolation of this biovar identifies the need for further investigations into the prevalence of brucellosis and the particular biovars involved in nomadic animals.
