Brucellosis

 

Brucellosis is a zoonosis(1), an infectious disease due to bacteria of the Brucella genus, which can affect most animals - domestic and wild species. This disease is thought to have existed since ancient times. « Malta fever»,« Undulant fever», «Mediterranean fever», «Melitococcosis» «Epizootic Abortion», different names given to the same disease, according to the place, the time and even the species that are concerned.

In animals, the infection may cause abortions in females, epididymo-orchitis in males and, less frequently, arthritis or bursitis in both.  Economic loss may be direct (abortion) or indirect (milk loss and sterility). However, the major economic issue is that French, European or International regulations state that only animals that come from officially free herds may be used for trade and even for the import of semen, ova and embryos.

Humans generally acquire the disease through direct contact with infected animals, by eating or drinking contaminated animal products. The signs and symptoms of brucellosis are extensive and they can be similar to many other febrile illnesses. Some individuals may develop long-term chronic symptoms, and may evolve to a chronic illness that may induce serious  complications, particularly at osteo-articular level.
