Brucellamelitensis is the main causative agent of caprine and ovine brucellosis. Sporadic cases caused by B. abortus have been observed, but cases of natural infection are rare in sheep and goats. Brucellosis is an infectious disease of many domestic and wild animals. Brucellosis is a major cause of direct economic losses resulting from clinical disease, abortion, neonatal losses, reduced fertility, decreased milk production, emergency slaughtering of the infected animals and treatment costs. It also plays a significant role as a barrier for international trade of live animals by being used as an impediment to free animal movement and export. Economic losses in small ruminants stem from breeding inefficiency, loss of lambs and kids, reduced wool, meat and milk production. Clinically, the disease is characterized by one or more of the following signs: abortion, retained placenta, orchitis, epididymitis and, rarely, arthritis, with excretion of the organisms in uterine discharges and in milk. Diagnosis depends on the isolation of Brucella from abortion material, udder secretions or from tissues removed at post-mortem. Presumptive diagnosis of Brucella infection can be made by assessing specific cell-mediated or serological responses to Brucella antigens. Brucellamelitensis is highly pathogenic for humans, causing Malta fever, one of the most serious zoonoses in the world. Identification of the agent Presumptive evidence of Brucella is provided by the demonstration, by modified acid-fast staining of organisms typical of Brucella in abortion material or vaginal discharge, especially if supported by serological tests. The polymerase chain reaction (PCR) methods provide additional means of detection.
